David N. Beratan Festschrift

David Beratan’s unique style of doing science has had a broad and deep impact on chemistry, biochemistry, and biophysics. He has developed theories with an eye toward influencing the design and interpretation of key experiments, and his impact has been tremendous. David’s insights and predictive models have opened up entirely new research directions to experimental inquiry: tunneling pathways, inverse molecular design, optimization of polarizability response through ground-state polarization, flickering resonance, and chiral imprinting are all examples of concepts that he has pioneered that have guided experimental designs and advances for decades.

First Accounts

Early-career scientists have some of the freshest ideas and are instrumental in pushing the frontiers of chemistry and related disciplines. Recognizing this, we have initiated the first in an annual series of virtual issues highlighting the publications in Accounts of Chemical Research over the past year that are authored by early-stage scientists: First Accounts. In addition to featuring early career researchers, each Account in this collection is the first article the corresponding author has published in Accounts of Chemical Research as a principal investigator.

First Accounts are also first-hand accounts—our junior faculty and newest researchers in industry and institutes are the most engaged in experimental design and execution in the laboratory, and we see this reflected in the writing from younger authors. In most cases, they have staked their careers on the success of the research program described in their Account, and justifiably, that passion for molecular design, mechanistic inquiry, and structural evidence comes through in their writing.

Complex Organic Molecules in Star-Forming Regions

This Virtual Special Issue is concerned mainly with a class of interstellar molecules that strongly resemble organic molecules present in the terrestrial organic laboratory. These molecules, known as “complex organic molecules”, a term abbreviated either as COMs or iCOMs, the “I” standing for “interstellar” since these molecules, containing from 6-13 atoms, are hardly complex when compared with the much larger molecules found on Earth. The COMs, which include simple alcohols, esters, nitriles, and ethers, have been observed extensively by radio astronomy. The wealth of material in this Virtual Special Issue concerning interstellar complex organic molecules should provide the reader with a comprehensive introduction to this burgeoning area of astrochemistry. If the 50-year history of astrochemistry is any guide, however, research in the future is likely to change some of the conclusions reached here. Nevertheless, the future work will be based on the solid foundation reported.

Area Selective Deposition: From Materials Chemistry to Nanofabrication

Right around 2014, as the minimum feature size of electronic devices approached 10 nm, nanofabrication needed a break-through technology to enable precise fabrication in 3D structures within the few nanometer scale. Area selective atomic layer deposition (AS-ALD) was recognized as having many advantages for this challenge because it is a bottom-up patterning approach with high conformality in 3D structures. The purpose of this virtual issue is to compile some of the recent, scientifically innovative papers in AS-ALD research published in Chemistry of Materials and other ACS journals for readers who are interested in this research field. Although the papers in this issue are focused on those published recently, we also include a few older published papers to provide some context about the main research history.

20th Anniversary of Aggregation-Induced Emission

2020 marks the 20th anniversary of the concept of aggregation-induced emission (AIE). Since the concept was first coined in 2001, it changes the way people think about chromophore aggregation and provides a broad platform for the design and development of new luminescent materials in practically useful solid state. AIE and the related interdisciplinary research have greatly promoted the continuous innovation and rapid development of chemistry, materials and medicine, which lay an important physical and theoretical foundation for related fields with substantial global impact. The collection of 30 recently published articles from these ACS journals highlights the dynamic and vibrant AIE research. This Virtual Issue will serve as valuable resources for both well-established and early career researchers to learn more about AIE.

Giants in Sensing: A Virtual Issue to Celebrate Five Years of ACS Sensors

As ACS Sensors celebrates its first five years of publication, we want to take this opportunity to honor people who have been central in shaping the field. To most scientists, chemical and biological sensing is a thoroughly modern discipline. It is unashamedly interdisciplinary, marrying fundamental insights and the foundations of analytical chemistry, state of the art materials science, bioengineering, electrochemistry, optics, biology, clinical and environmental chemistry. It addresses important measurement science challenges that face us today. This is what motivates many of us to contribute to this important field. Together with Analytical Chemistry and the Journal of the American Chemical Society, we present a virtual issue on Giants in Sensing featuring some fifty articles from influential sensing researchers who have contributed to any of these journals in the past five years. Please go through the list, read these excellent articles, and be sure to remember their names and those that came before when you write your next publication. It is humbling to know that we are all standing on the shoulders of giants.

Natural Products: Isolation, Total Synthesis, Structure-Activity Relationships, and More

Chemists are known for their ability to design and create molecules and materials—it is at the heart of what we do. Many of our ideas originate with the ultimate molecular designer and synthetic engineer, Nature, which has found an elegant way over time to create the necessary molecules of life or ones that participate in life cycles. Much of the new chemistry involving these natural products ends up on the pages of Organic Letters and The Journal of Organic Chemistry each year, pieced together through total synthesis to guide the way toward developing new and improved medicines, agricultural chemicals, biocatalysts, and more.

In this Virtual Issue, we feature 40 leading articles on natural products chemistry, selected by Organic Letters Editor-in-Chief Erick M. Carreira and The Journal of Organic Chemistry Editor-in-Chief Scott J. Miller from among the more than 250 articles on the topic published in the ACS core organic journals during 2019.

Quantum Dots and their Applications: What Lies Ahead?

It has been many years since the first works on the reduced dimensionality of semiconductors, which led to the concept of ‘artificial atoms’, or quantum dots (QDs). These semiconductor nanocrystals, with nanometer-sized diameters, exhibit quantum size effects in their optical and electronic properties. In particular, tunable and efficient photoluminescence (PL), with narrow emission and photochemical stability, as well as core-shell structures are commonly achieved today for many quantum dot materials systems. As a consequence, quantum dots have been incorporated as active elements in a wide variety of devices and applications, such as light-emitting diodes and display applications, photovoltaics, photoconductors and photodetectors, biomedical and environmental applications and catalysis applications. Many of these applications are now commercially-available and incorporated into our daily life, such as the case of quantum-dot-based displays. Despite being now part of mature technologies, quantum dot synthesis, characterization, and applications still constitute a highly active field of investigation. In light of various new development in applications of quantum dots, it is our pleasure to announce a “virtual issue” on quantum dots and their applications for ACS Applied Nano Materials.

International Symposium on Molecular Spectroscopy

The collection of papers in this virtual special issue of the Journal of Physical Chemistry A are representative of the work disseminated over the last decade at the International Symposium on Molecular Spectroscopy (ISMS), which is on the verge of its 75th anniversary. The ISMS was founded in 1946 and was held on campus at The Ohio State University for 68 consecutive years, where after it moved to the University of Illinois Urbana-Champaign. Historically, the emphasis of the ISMS has been the characterization of the structure, dynamics, and spectroscopy of molecular systems, including complexes and clusters. The fundamental spectroscopic techniques developed by the participants of ISMS have been applied over the years to an ever more precise understanding of the chemistry and physics of aqueous environments, combustion, the interstellar medium, and planetary atmospheres, to name a few of the more popular areas of discussion at the symposium. This research, in both the gas and condensed phases, spans the subject areas of JPC A.

3D Printing of Polymers

The distributive manufacturing enabled by 3D printing has been on display in the response to shortages in critical medical resources for the response to the COVID-19 epidemic. In almost all cases, these 3D printed parts have been polymers and have been instrumental in providing a stopgap to logistical challenges in obtaining critical components. These have included, amongst many other examples, engineered solutions to limited number of ventilators through 3D printing of valves for ventilators, parts to transform snorkeling masks into continuous positive airway pressure (CPAP) devices, and repurposing of existing medical equipment to meet demands for treating patients. The timely delivery of these 3D printed plastic components has been enabled by the advances in 3D printing over the past decades. In light of their acute significance in this global health crisis, it is our pleasure to announce a “virtual issue” on the 3D printing of polymers for ACS Applied Polymer Materials.
