Call for Papers: Lattice Dynamics

Crystal lattice dynamics impact a wide range of bulk physical properties, from thermal expansion to superconductivity. While the relationship between lattice structure and crystal properties is a well-established area of study, the role of specific vibrational motions on crucial condensed phase properties has only recently been uncovered. This discovery has opened up new and exciting areas of research, including phase transformations, mechanical and thermomechanical responses, charge carrier dynamics, and gas adsorption in porous crystals. The dynamic lattice plays a profound role in dictating both the equilibrium properties of materials as well as their response to external stimuli. 

Lattice dynamics occur across a large frequency range and involve a variety of vibrational modes that are often interconnected. This complexity requires new experimental tools to probe the lattice dynamics and, from a theoretical perspective, there exists significant opportunity to understand the properties of crystals through the lens of atomic and molecular dynamics.

Sodium: Leading the Charge Toward Better Batteries

Society is moving toward smart electronics that require flexibility, resilience, and safety—and most importantly, a sustainable and cost-effective way to keep them running. Several recent studies have demonstrated the potential for sodium-ion batteries to one day be a practical, cheaper replacement for current lithium-ion technology.

The Lithium Problem

Batteries are everywhere. From toothbrushes to cars, batteries are responsible for powering many of the devices that help us go about our daily lives without constantly needing to be plugged in to an electrical outlet. If you are currently using a laptop or portable device, there’s a likely chance you are reading this post thanks to battery power.

Over the past several decades, lithium-ion batteries (LIBs) have come to dominate the rechargeable battery industry and are now the go-to power source for the majority of portable electronic devices and gadgets. LIBs far outperform other rechargeable alternatives due to their high energy density, ability to hold a charge over long periods of time, and resilience to frequent charge cycles.1

As beneficial as they are, lithium-ion batteries also come with significant drawbacks that may hinder long-term production and applications. The limited availability of lithium, cobalt, and other raw materials cannot meet the growing global demand for lithium-ion technology—and the extraction process is costly, hazardous, and environmentally detrimental. Furthermore, despite LIBs being generally safe, they are still susceptible to overheating—or in some cases, exploding—if exposed to certain conditions.

But now, new studies aim to identify viable lithium-free battery alternatives in hopes of establishing cheaper, safer, and more environmentally sustainable options for powering our devices in the future—and a number of researchers have developed a particular interest in sodium-ion technology as a potential replacement.2

Advantages and Challenges of Sodium-Ion Technology

Sodium-ion batteries (SIBs) offer several key advantages compared to their lithium-ion counterparts. In terms of raw material availability, sodium is the clear winner. It is at least one thousand times more abundant in the earth’s crust than lithium and much cheaper to obtain. 3 It can also be extracted through more environmentally friendly processes such as seawater desalination.

Despite these advantages, there are still significant hurdles in the way of more widespread, practical SIB applications. One challenge involves the limitations of sodium-based layered transition metal oxides (TMOs) as cathode materials—notably, lower specific capacity and energy density resulting from a more convoluted charge-discharge cycle.4

One recent study explores anionic redox reaction (ARR) as a favorable method to boost capacity and improve the overall performance of SIB cathode materials. Although ARR-based cathode materials are encouraging for greater storage capacity, other challenges still remain, and more research is necessary to fully understand the fundamental chemistry of ARR before it can be successfully applied within SIB technology.4

In addition to lower specific capacity and energy density compared to LIBs, liquid SIBs are susceptible to an array of safety hazards that have severely hindered future developments and progress toward commercialization. Researchers have proposed solid-state sodium metal batteries (SSMBs) as suitable alternatives due to their improved energy density, lower cost, and high stability. However, their solid-state electrolyte (SSE) components often demonstrate low ionic conductivity and various interfacial compatibility challenges, which can ultimately impede electrochemical performance.5

With these challenges in mind, sodium- or zinc-based hybrid supercapacitators may become an appealing option for commercial applications by providing a mashup of two different energy storage technologies. By combining a capacitator-type cathode with a battery-type anode, these hybrid storage devices can achieve high energy density without compromising stability or power delivery—but challenges remain even here, and more research is crucial for making pragmatic hybrid supercapacitator applications a reality.6

A Better Way to Power Our Lives

Although sodium remains a top contender for next-generation batteries, the technology is not quite there yet. Identifying more effective cathode materials will help to build powerful, stable SIBs with greater specific capacities. Further research should also focus on advancing battery electrolyte technology so that SIBs can successfully perform over a wide temperature range while maintaining the long charge cycles and lifespans required for large-scale energy storage.3

As we continue progressing toward widespread sustainable energy sources such as wind or solar power—all of which depend on battery storage for uninterrupted performance—researchers are optimistic that sodium-ion technology will pave the way toward more cost-effective, sustainable, and powerful batteries.

Microplastics: A Macro Problem

Microplastics are becoming a ubiquitous ecological contaminant. Chemists in diverse fields are attempting to better understand the behavior of microplastics and develop novel solutions to limit their impact, both on human health and ecosystems. Below are some recent highlights within this field of research.

The Scale of the Problem

Microplastics are defined as small plastic pieces and fragments less than 5 mm in length. These present a problem for wildlife, plants, and humans—and it is a problem that keeps growing. It is estimated that more than 3 million metric tons of microplastics enter the environment each year. These come from a variety of sources, from vehicle tires and road markings to clothing and cosmetics.  As a result, the average person eats, drinks, or inhales up to 211,000 microplastic particles every year—or about 250 grams.1

Impact on Human Health

Several recent studies published in Environmental Science & Technology reveal various effects of microplastic pollution on the human body. One study analyzed phlegm samples from people with various lung diseases, and the researchers found microplastic accumulation in everyone tested. In total, 21 types of microplastics were identified; polyurethane was the dominant culprit, followed by polyester, chlorinated polyethylene, and alkyd varnish.2 Researchers in China have also revealed a positive correlation between the concentration of microplastics in fecal matter and severity of inflammatory bowel disease.3

Microplastic accumulation may also occur in our bodies before we are even aware of our own existence. A recent study has demonstrated the first evidence in humans of an association between microplastics and microbiota in placental and meconium samples—suggesting microplastics are altering human biology even before birth.

What’s the Bigger Picture?

These tiny particles are an environmental disaster in their own right, but it is also becoming increasingly clear that they can carry other pollutants and contaminants on their surfaces. In fact, microplastics seem to have an unexpectedly high affinity for heavy metals, a trend that has been found in environmental samples worldwide. For example, researchers have demonstrated that UV filters from sunscreens can make chromium metal take on a different, more toxic oxidation state when attached to microplastics.5

This study provides the first evidence into how microplastics can turn heavy metals and pollutants into more harmful versions of themselves. As microplastics continue to accumulate in our bodies and in the environment, more comprehensive assessments are necessary to better understand the extent to which these complexes are affecting our health.

Assessing the Risk

Understanding microplastics’ long-term degradation behavior and environmental presence is essential for risk assessment and reporting. Part of this includes being able to differentiate size classes and degradation states over time. One study sets out a protocol to better assess microplastic degradation rates and quantify the release of micro- and nanoplastic fragments down to 10 nm.6 The researchers created a simulated beach environment to observe the effects of UV aging, hydrolysis, and mechanical stress on environmental degradation and fragmentation.

The results show that previously formed fragments can further degrade into water-soluble organics with measurable rates, which is promising for enabling future modeling approaches. The researchers report that further identification and risk assessment of these dissolved species will be important for future work, as well as assessing scenarios and stresses beyond UV degradation.

The Secret of Spinning

For centuries, humans have used the fibers from silkworm cocoons for luxury fabric making; now, these humble caterpillars could be the inspiration for a whole new generation of biomedical applications.

Read the Original Article

Nanofibers are a promising candidate for making diverse functional materials from flexible electronics to wound dressings.  But human-made nanofiber spinning methods can be convoluted and inefficient, sometimes resulting in clumpy or inconsistent fiber output.

To improve upon this, scientists have looked to the natural world for tips and tricks on creating the perfect fibers. In nature, animals such as spiders and caterpillars have evolved unique spinning processes that can create high-performance natural fibers.

The silkworm (the caterpillar of the Bombyx mori moth) spins its fibers via an adhering–pulling–adhering process. To achieve this, the silkworm first spits out silk coated with sericin to adhere to the chosen surface for its cocoon, before swinging its head up to pull the silk out of the adhesion spot—and finally pulling the silk and sticking it to the next adhesion spot.

The silkworm does not appear to need any sophisticated structure to eject the fibers or provide significant external forces; rather, it appears to be the initial adhesion on an external spot that is the key enabler for continuous spinning. This is unlike the method used by spiders, who have nozzle-like spinnerets on their abdomens to enable them to spin their webs.  

Inspired by the simple approach of the silkworm, new research published in Nano Letters describes a micro-adhesion-guided (MAG) spinning technology for instant and on-demand fabrication of micro- and nanofibers.1 This uses microscale adhesion between the spinning fluid and its contact point. Fundamentally, the fiber formation is primarily a result of the liquid motion driven by surface tension, adhesion force, and capillary force.1

The researchers explored this using two key methods. First, they used a microneedle with spinning polymer fluids fed through a microfluidic array to produce oriented, cross-linked, and all-in-one fibers. The second simplified version harnessed the natural roughness of foam to act as the micro-adhesion points—simply pulling two polymer-soaked pieces apart to instantly spin threads in the gap between them.

These results present exciting opportunities for in situ fiber-fabrication technology without the need for any specialized equipment, which could prove especially valuable for biomedical engineering. For example, the strands created with MAG spinning could be placed directly on a person’s skin to create instant, flexible bandages—and including an antibiotic in the polymer solution for the bandage fibers could open further possibilities for biomedical applications.

The researchers believe this new method will help avoid the traditional issues with current spinning techniques, bypassing the need for significant external forces to either overcome surface tension or pass through a mold—all thanks to inspiration from the tiny silkworm.

Meet Jinlong Yang, the Editor-in-Chief of New ACS Partner Journal Precision Chemistry

Professor Jinlong Yang, Editor-in-Chief of Precision Chemistry

ACS Publications is excited to announce Professor Jinlong Yang as the inaugural Editor-in-Chief of Precision Chemistry, a new partner journal between the University of Science and Technology of China and the American Chemical Society. Professor Yang is a professor of chemistry at the University of Science and Technology of China (USTC), where he received his PhD in condensed matter physics in 1991 and has served as Vice President since 2018.

We connected with Professor Yang recently to learn more about him, his research, and his hopes for the future of Precision Chemistry. These are the highlights of our conversation.

What is precision chemistry and why is it so important to scientific research?

Precision chemistry as a concept mainly covers two aspects. First, chemical research generates a large number of data, which needs to be accurate and reliable to obtain precise physicochemical pictures. We increasingly need higher precision in computational simulation and experimental characterization.

Second, traditional chemical research relies heavily on the method of “trial and error.” As the discipline has developed, the precise control of chemical reaction paths and tuning the properties of molecular and material systems have become increasingly important. As a result, precision synthesis and manufacturing based on such abilities is another important and growing research goal.

To sum up, precision chemistry aims to use and develop theories and experimental methods to improve the precision of chemical research, so as to realize precise calculation, design, synthesis, characterization, manufacturing, etc., and improve the efficiency of chemical research.

So precision chemistry can provide improved efficiency, better performance, and increased environment friendliness—this is the dream for chemists. On the one hand, demand for precision in chemical research comes from the development of chemistry at the level above the molecular, and the exploration and understanding of the construction, properties, and the nature of intermolecular interactions of complex chemical systems such as macromolecules, supramolecules, molecular aggregates, and even living systems – focusing on multi-scale effects in chemical processes.

On the other hand, it comes from the requirements for the creation of new substances beyond the “trial-and-error” research paradigm to achieve sustainable development of human society and to fundamentally solve energy, environmental, and health problems. Precision chemistry will have a significant impact on many areas of scientific research.

Why is the new journal Precision Chemistry open access?

Precision chemistry is at the frontier of chemical research. Future developments cannot be achieved without interdisciplinary cooperation and the combined efforts of scientists from many fields relevant to chemistry. And further, to accelerate this cooperation, we need to increase the accessibility and usability of articles published in Precision Chemistry—which is the only journal focusing on precision in chemistry. Based on these considerations, we decided to adopt an open access publishing model for Precision Chemistry.

How important is it for you to be supported as Editor-in-Chief by your fellow Editors?

The success of any journal is dependent on editorial teamwork. The support of team members is very important for my work and the development of Precision Chemistry. We have established a prestigious and truly international editorial team, whose expertise covers many fields of chemistry for Precision Chemistry. I believe Precision Chemistry and the fields it serves will evolve quickly thanks to the collaboration within our team.

What excites you about your current research in the field?

The most exciting part of my own work in the field of precision chemistry is to make things possible that initially seemed impossible. Taking electronic structure calculation as an example, we can only deal with very small system containing a few atoms if we solve the Schrödinger equation directly without making any approximation. As a result, high precision calculations of the electronic structure of complex chemical systems containing tens of thousands of atoms were considered to be out of reach a few years ago. But recently, we developed algorithms to use a supercomputer with 40 million cores to perform the density functional theory calculation of a complex lithium-sodium alloy system containing 2.5 million atoms in parallel. This greatly expands the application scope of high-precision electronic structures.

And the gradual application of quantum computers promises to continue to expand this range significantly. In addition, the precise control of chemical synthesis is also greatly improved through the development of artificial intelligence algorithms to build a robot automation platform. With such precision synthesis technology, experiments that would previously have taken decades can be completed in a few days. These emerging new advances will drive the development of precision chemistry.

Why should people doing work in the field submit their next best manuscript to Precision Chemistry?

Although much of the previous work in chemical research fell into the realm of precision chemistry, it was published across different journals that focused on different fields of chemistry. Bringing this work together under the banner of precision chemistry will greatly enhance the overall impact of these many different but related topics. We hope that Precision Chemistry will clearly convey the significance of the goal of precision across many branches of chemistry and related disciplines and will enhance the influence and impact of precision chemistry in the scientific community.

Where do you see research in precision chemistry going in the field in the next 5-10 years?

In the next 5-10 years, we will see significant improvement in the precision of computational modeling and experimental characterization of complex chemical systems. A large number of precise chemical data will then be generated, enabling chemical intelligence to be established based on big data, which ultimately allows the precise tuning of the properties of chemical systems and chemical reaction paths.

Possible future advances include but are not limited to:

  • achieving precise detection, imaging and characterization of molecules and chemical reactions
  • conducting theoretical modeling of chemical, biological and material systems with high accuracy and computational efficiency
  • realizing precise and controllable chemical synthesis with high selectivity and efficiency
  • creating molecular machines and devices based on molecular engineering of complex and multi-functional molecular systems
  • achieving controllable self-assembly with precise designed structures, precise synthesis of macromolecular and supramolecular systems
  • realizing precise regulation of nanostructures
  • fabricating high-performance functional materials based on rational design
  • applying precision chemistry to complete gene editing, protein and enzyme engineering, molecular diagnosis, and targeted therapy
  • solving important issues in energy and environmental sciences including energy conversion, energy storage, water resources, environmental remediation, carbon neutrality, and so on.

What advice would you give to young scientists today?

I think it is very important for young researchers to think about the big questions and identify a research goal that has important scientific value. Young researchers are creative and should not blindly chase hot spots and just undertake research superficially. They can both greatly improve the overall research endeavour and create new opportunities for themselves.

Kelly Chibale Named Editor in Chief of ACS Medicinal Chemistry Letters

Kelly Chibale Headshot

ACS Publications announced the next editor in chief of ACS Medicinal Chemistry Letters will be Kelly Chibale, Neville Isdell chair in African-centric drug discovery and development, and professor of organic chemistry at the University of Cape Town (UCT). Chibale, now an associate editor with Journal of Medicinal Chemistry, will begin his term on January 1, 2023, replacing Dennis C. Liotta, the inaugural editor in chief of the journal that launched in 2010, who is stepping down at the end of 2022.

Chibale will be the first editor in chief of an ACS journal from Africa. He is also founder and director of the UCT Holistic Drug Discovery and Development Centre, the South Africa research chair in drug discovery at UCT and founding director of the South African Medical Research Council/Drug Discovery and Development Research Unit at UCT’s Institute of Infectious Disease and Molecular Medicine.

“Chibale is a pioneer and a leading synthetic organic chemist whose research has largely contributed to the global health drug discovery. We’re thrilled he chose ACS,” said James Milne, president of ACS Publications in a statement. “Aside from numerous awards and honors, including being named one of Fortune magazine’s 2018 world’s 50 greatest leaders, Chibale has been an active ACS member since 1994, underscoring his commitment to ACS and our shared mission.”

Meet Professor Chibale at the University of Bonn

One of Professor Chibale’s first events as ACS Medicinal Chemistry Letters editor in chief will be the ACS Publications Symposium on Biological and Medicinal Chemistry in Bonn, Germany, March 6-8, 2023. It’s free to register for the event hosted in partnership with the University of Bonn.

The Symposium will feature three days of in-person talks by leading researchers in biological and medicinal chemistry from EMEA institutions and industry—many of whom, like Chibale, are also editors of high-impact ACS journals. It will also include a poster session and networking sessions with speakers, attendees, and ACS Publications staff.

“Bridging the gap between fundamental basic science and clinical research to advance innovative medicines discovery requires, amongst other things, the integration of chemistry with biology and pharmacology, including drug metabolism and pharmacokinetics studies,” says Chibale. “In my talk I will be describing the establishment of chemistry, biology and pharmacology platforms at our University of Cape Town Holistic Drug Discovery and Development (H3D) Centre and how these platforms have been deployed in drug discovery projects underpinned by medicinal chemistry and chemical biology in mechanism of action deconvolution.

“I am excited about visiting Germany partly because Bonn, which is on the banks of the Rhine River, is a beautiful city and partly because Germany is a global scientific powerhouse with a rich chemistry history.  Not so long-ago German was the language of chemistry!”

An Interview with Professor Kelly Chibale

I connected with Professor Chibale recently to learn more about him, his research, and his hopes for the future of ACS Medicinal Chemistry Letters. These are the highlights of our conversation.

How would you describe your research to a non-scientist?

My research is two-fold: First is the discovery of future innovative, lifesaving medicines for infectious diseases with attendant studies to understand how the medicines work. Second, is scientifically addressing the issue of health equity from an African perspective.

In this context my research is focused on building (currently non-existent) Africa-specific preclinical discovery phase tools and models to contribute to improving treatment outcomes in people of African heritage. Regarding the latter research area, it is noteworthy that Africa is arguably the most genetically diverse continent.  The status quo is such that medicines are not optimized for the African patient population for two main reasons.

First, although Africa accounts for 15% of the global population and 25% of the global disease burden, there is an extremely low volume of clinical trials (2-3% of global total) that take place on the continent. The implications of this are that:

  1. African perspectives on intrinsic factors [such as physiology, genetics, etc.], and extrinsic factors [such as the practice of medicine, when during the stage of a disease (early vs late) that a patient presents for treatment, concomitant medication etc.] are not considered during the clinical drug development stages.
  2. Clinicians and patients in Africa only acquire experience and access to newer therapies much later in time than those who work and live in the more developed nations.

Second, there is absence of preclinical tools—such as hepatocytes and liver microsomes used for drug metabolism studies, which rarely have African populations.  Pharmacokinetic variation in African populations due to variable genetic expression and activity of drug metabolizing enzymes and transporters are not well accounted for.

This has implications on human dose prediction for clinical trials, in particular Phase 1 or First-In-Man, studies. Having the Africa-specific preclinical discovery tools will not only facilitate the prioritization of drug candidates during their (chemical) lead optimization phase based on their predicted pharmacological profile in African patients, but generated data will also be useful in stratifying patients for clinical trials.

What element has been most central to your scientific career, and why?

My answer can be summed up in what the French biologist, microbiologist, and chemist Louis Pasteur (1822-1895) had to say: “The more I study nature, the more I stand amazed at the work of the Creator.  Science brings me nearer to God.”

Pasteur also said, “little science takes you away from God but more of it takes you to Him.”

What is your vision for ACS Medicinal Chemistry Letters moving forward?

I must first hasten to acknowledge the foundational work done by my predecessor and founding editor in chief, Dennis C. Liotta. His vision, leadership, drive, and creativity have brought the journal to its current strong position of being the leading journal in its league, ahead of its direct competitors. So, I will be standing on the shoulders of this giant in Dennis.

My vision is to build on the excellent foundation laid by Dennis and the editorial board, past and present, to build a more globally diverse and inclusive community of the future in terms of geography, race, gender, age, and employment sector, and ensuring that ACS Medicinal Chemistry Letters effectively serves this community in the long term.

What types of advances in medicinal chemistry and drug discovery do you hope to see published in the journal over the next decade?

I would like to see increased publications in infectious and neglected tropical disease arenas, medicinal chemistry of vaccine adjuvants and RNA-based therapeutic strategies. I would also like to see medicinal chemistry embracing high molecular weight (non-Lipinski ‘rule of 5’) chemical space and large peptides, biologics and long acting injectables with associated drug metabolism and pharmacokinetics studies.  Finally, as precision medicine gains momentum, I would like to see medicinal chemistry integrated with preclinical tools aimed at prioritizing drug candidates based upon their predicted pharmacological profiles in specific patient populations.

When you’re not teaching and doing research—and working as a journal editor or reviewing papers—how do you spend your time? What are your passions outside of medicinal chemistry and your workday?

I spend most of my time outside work with my wife Bertha talking and laughing a lot. We have 3 grown-up sons: Kalaba, Suwilanji, and Sechelanji.

When at the local gym, I love hitting the punching bag with a variety of punches like a boxer in training to defend a world title. Outdoors, I love hiking in forests towards mountains. Being based in Cape Town, one of the most beautiful cities in the world, which is also known as the Mother City but which I like to call The Promised Land, I am surrounded by the incredible Table Mountain, one of the New Seven Wonders of the world. Bertha and I hike every week when we are both in town.

ChemRxiv: From a User’s Perspective

In August 2022, ChemRxiv organized a panel discussion at the ACS Fall Meeting in Chicago. We sat down with one of the panelists, Julia Kalow, Assistant Professor of Chemistry at Northwestern University, to find out more about how she utilizes ChemRxiv in her lab:

Can you tell us a bit about your research focus?

We are organic and polymer chemists interested in controlling the synthesis and properties of polymers with light. I’m interested in looking at materials that change over time, under stimuli or during reactions, through the lens of “reactivity-property relationships”, which we think of as a dynamic version of conventional structure-property relationships.

You’ve posted a number of preprints onto ChemRxiv. When did you first learn about preprints and ChemRxiv?

Several of my senior colleagues, such as Will Dichtel and Franz Geiger, were early adopters, and their enthusiasm convinced me to use it.

What do you see as the main benefit of posting a preprint?

As an early-career scientist, I need to be able to show the community what we’re working on, even as our manuscripts are making their way through the (often slow) peer-review and revision process. This is particularly true since I have switched fields, and for proposals, preprints can demonstrate our expertise in a new area while we are waiting for the final published version to come out.

What has the reception been like to your work on ChemRxiv?

Some of our preprints have been cited, and while it’s hard to know how “views” translates to actual reading or impact, it is interesting that some of our preprints have been viewed more times than the published version!

You mentioned at the event at the ACS National meeting that you also use preprints in your teaching, can you tell us more about how you do that?

In my Polymer Chemistry course, for the final project, the senior undergraduates in the class pick a preprint from ChemRxiv related to polymer chemistry and prepare a peer review for it. As preparation, they complete the ACS Reviewer Lab training and I do a lecture on peer review during class, and I also provide a template for their reviews. I think that preprints are the perfect context for this exercise because they are actually reviewing manuscripts that may not have been through the review process, and need to make a judgement call that is divorced from the perceived prestige or impact of a journal.
