The Recipe for a Successful Research Submission

research submission

A successful research submission is like a well-made dish: There’s a handful of key ingredients that take it from mundane to noteworthy. While almost every researcher has scratched their head and wondered why they were rejected, very few stop to consider why an article was accepted. While every researcher’s recipe for success differs slightly, there are a few essentials that will help you hone your publishing expertise. Below, you’ll find a list of key ingredients to make sure your next research submission is seasoned to perfection. This list is compiled from articles within the Virtual Issue of Editor Tips for Authors Mastering the Art of Scientific Publication.

An Engaging Title

Pick an attractive title that fits your research and appeals to a broad audience. Use caution regarding words such as Highly Efficient, Novel, Significant Enhancement, etc., since they may overemphasize the importance of your research. Similarly, avoid words such as Study, Investigation, Demonstration, since they may undermine the uniqueness of your work.

Relevant, Well-Composed Research

Make sure your paper has a clear focus and addresses an important issue that falls within the journal’s scope. Significant findings should be identified in the abstract, the introduction should provide the motivation for the study, while the discussion is central to the paper’s theme, and results and cited references are all relevant to the journal’s field.

A Properly Formatted Manuscript

Different journals have different formatting guidelines. Always carefully review the journal’s “Instructions to Authors” before submitting your research.

Well-Drawn Figures and Schemes

All figures and schemes should be self-explanatory and use correct scientific notation.

Contributors and Funders are Properly Acknowledged

Would this paper be here without this contributor/funder’s assistance? If not, they should be acknowledged. 

Suggested Reviewers are Appropriate and Have No Conflict of Interest

While E=editors do not necessarily use your suggested reviewers, these recommendations greatly assist an editor in obtaining additional qualified reviewers based on the area of expertise. Authors should inform the editor if suggested reviewers are former students or current collaborators, or if another potential conflict of interest may be present.

All Coauthors are Onboard With the Final Manuscript

Before submission, make sure all coauthors have seen the final manuscript and had a chance to comment on it.

In the Lab with Timothy Lodge

Timothy LodgeAt the highest levels of research, it can be easy to become nearsighted, focusing only on your own narrow specialty. Thankfully, that’s not the case with Timothy Lodge. Lodge is a Regents Professor in the Department of Chemistry and Department of Chemical Engineering and Materials Science at the University of Minnesota. He’s the Editor-in-Chief of Macromolecules (a position he’s held since 2001) and the founding Editor-in-Chief of ACS Macro Letters.

Lodge prides himself on the collaborative, interdisciplinary nature of his lab. While most polymer chemistry labs focus on either synthesis or properties, Lodge and his colleagues tackle both. They combine synthesis of model polymers, especially block copolymers, with advanced physical characterization tools.

“Our set of experimental tools is almost unmatched in breadth,” Lodge says. “It routinely includes scattering tools like light, neutron, and x-rays; microscopy tools such as TEM, SEM, and cryoTEM; rheology; and NMR.”

The lab’s scope attracts students and collaborators from far and wide. Students come from Ph.D. programs in chemistry, chemical engineering, and materials science; many are co-advised by professors with other areas of expertise. Because the lab’s work is at the intersection of fundamental science and technological applications, research is funded both by government agencies such as NSF and companies.

This openness has led to interesting discoveries. For example, Lodge and his colleagues recently revealed a new understanding of methylcellulose (MC), a commercial product used in food, pharmaceutical products, and building materials. It has been used for more than 100 years, but its gelation and phase separation properties were never understood—until now. “Our team showed for the first time that MC actually self-assembles into 15 nanometer diameter fibers on heating, a completely unanticipated result,” Lodge says. “This discovery will enable a suite of new applications for MC and related sustainable polymers.”

Other accomplishments include the development of “ion gels,” soft solids with many of the properties of the constituent ionic liquid. Researchers have used these gels as the so-called gate dielectric in organic transistors and shown that they outperform all other candidate materials. They’ve also made luminescent gels for display applications, and thermoreversible and photoreversible gels that can be processed in the liquid state and solidified on demand.

Timothy Lodge’s interests outside work are similarly broad. You’re as likely to find him hiking outdoors as taking in a classical music performance. He’s an avid football fan—though not the kind you might think. Lodge was born in England, and follows Premier League teams Manchester City and Manchester United.

He’s well respected by his students. Cecilia Hall is a third-year graduate student in Lodge’s lab, studying block polymers in ionic liquid.

“Dr. Lodge doesn’t micromanage, but he’s accessible when I have questions,” she says. “He’s helping me develop into a scientist.”

Energy & Fuels: Past, Present & Future With Michael T. Klein

In celebration of Eath Day 2016, Energy & Fuels Editor-in-Chief Michael T. Klein discusses the state of energy research.

You’ve been the EIC of Energy & Fuels since 2002. How has the field of energy and fuels research changed in that time? 

The most significant change is that virtually all possible energy solutions are placed in and motivated by an environmental context.  This is a very healthy development in the field of energy and fuels. This is true for all energy solutions, ranging from the use of fossil fuels in a clean and sustainable manner to the development of carbon-free alternatives.

 You’ve recently published two paper on gasification of plastics and biomass. What are the major challenges in the waste-to-energy technology space? 

The major scientific challenge is to sort through the complexity of the gasification feed stocks and reaction networks to allow fundamental chemistry to help in the optimization of the problem.  The technological issues are similar to those found in other large-scale energy unit operations.

What do you think of media coverage of energy research? Are there areas you wish got more attention? Less? Are there misconceptions you wish you could clear up?

The media coverage is widespread and very useful.  The challenge is that the overall energy landscape is very diverse and challenging and difficult for one person to understand. Thus we rely on the media for information and analysis.  The balance of objective analysis and advocacy for any one position is important and should be a conscious part of media coverage.

What areas of energy research do you personally find most interesting? Are there topics you think all researchers in the field should monitor closely?  

The energy field contains a very diverse collection of potential solutions.  The underlying science can be very different.  I find those that involve chemistry to be most interesting because I have the best chance to follow the details.  I also find the science and technology of other potential solutions to be very exciting, both because of their impressive science and engineering content and the societal impact they represent.

Chemical Research in Toxicology: The Place for Chemists Curious about Contaminants

ACS-2833 Toxicology Axial 750x354

“‘Chemophobia’ is spreading,” says Janice E. Silverman, Acquisitions Editor of Chemical Research in Toxicology. “Everything is perceived as toxic.”

Many people may overestimate the dangers posed by “toxic” substances in their everyday lives, but toxicology research plays an undeniable role in our understanding of contaminants to the environment and living species.

“Toxicology tries to determine why a species suffers from exposure to a specific contaminant, looking at biological processes and pathways involved and the mechanism of actions,” Silverman explains. “Research and methods currently being developed in this field play an increasing role in the assessment of pollution, impact, and remediation.” 

Chemical Research in Toxicology is the prime source for scientists working on these problems. The journal publishes papers on the molecular mechanisms by which chemical and biological toxic agents interact with living systems to cause cellular damage. It also highlights studies on interactions of toxic agents with living systems. “It’s a venue for all aspects of the chemical basis of toxic responses,” Silverman says.

Changing Rates for Liver and Lung Cancers in Qidong, China

Chem. Res. Toxicol.201427 (1), pp 3–6
DOI: 10.1021/tx400313j

Residents of Qidong, China are undergoing rapid changes in the incidence rates of many types of cancer. This article examines the liver and lung cancer incidence rates tracked by the Qidong Cancer Registry for the past 40 years. Lung and liver cancer are the two leading cancer killers in Qidong, and both are influenced by environmental factors. The incidence rate for liver cancer has dropped significantly in the last 4 decades. On the other hand, lung cancer has increased among men in Qidong in the same time period, likely due to an increase in smoking. The rate of lung cancer was steady among women until the past decade, with the upturn possibly reflecting an increase in indoor and outdoor air pollution.
