Could you briefly explain the focus of your article to the non-specialist (in one or two sentences only) and why it is of current interest?

Electrochemical methods are well-suited to reduce toxic hexavalent chromium to purify drinking water, but the challenge is mitigating the energetic cost associated with the transfer of the large number of protons and electrons required all while using cheap carbon electrodes. Here we show how the choice of buffer, not simply the pH, influences the reaction and we also demonstrate a very simple way to recycle electrodes if they get fouled during use.

How big an impact could your results potentially have?

The work helps establish that in the conditions studied: 1) cheap carbon electrodes can be used instead of noble metals, 2) Cr(VI) reduction is gated by a similar proton-coupled electron transfer step in multiple buffers, 3) some buffers promote adsorption of the resulting Cr(III) on the electrode, and 4) it is possible to restore the electrode surface and regain activity with a simple rinse, without the need for re-polishing. Combined, these open the way to the development of water purification flow systems to reduce Cr(VI) in water.

Could you explain the motivation behind this study?

The motivation is to advance electrochemical water purification, specifically targeting toxic hexavalent chromium, by leveraging knowledge from the community working on Proton-Coupled Electron Transfers. At its core, the challenge of Cr(VI) reduction is the efficient transfer of multiple protons and electrons. This is thermodynamically easy but kinetically challenging. Before developing catalysts to mediate the transformation, it was important to identify the parameters influencing direct electroreduction of Cr(VI) at an electrode.

In your opinion, what are the key design considerations for your study?

Realizing that buffers are not inert innocent spectators! We are so used to thinking of buffers in water as a means to work at a fixed pH, without really considering the effect of the specific acid/bases added.

Which part of the work towards this paper proved to be most challenging?

Experimentally, the observation of Cr(III) plating on the electrode in certain conditions significantly increased the time required for data collection as freshly polished electrodes were required for every single scan. Scientifically, realizing that the buffer was the cause of these changes in behavior was the most challenging.

What aspect of your work are you most excited about at the moment?

I am excited about our progress on developing electrocatalysts to further mediate the Cr(VI) reduction transformation, as well as applying lessons learned to other problematic oxyanions contaminating water supplies.

How has your research evolved from your first article to this particular article?

Our fist paper on this project demonstrated that carbon electrodes are effective for the reduction of Cr(VI) in water across a wide range of pH. We were using a citrate buffer for that work as we were covering a large pH range. In this new paper we explore how that seemingly innocuous choice of buffer actually impacts many steps of the Cr(VI) reduction process.

What is the next step? What work is planned?

We would like to develop electrocatalysts to speed up the reaction and, critically, decrease the energy required (lowering the overpotential). We have made progress in that direction and hope to be able to share more soon.

Why did you want to publish in RSC Advances?

I value the RSC as a non-profit scientific society. I also love the ease of submitting papers to the RSC when using the template, with auto-populating fields which speeds up the submission process. I chose RSC Advances specifically as it is a general journal with a broad audience.

What are your thoughts on open access publishing?

It is fantastic to hear that the RSC, and others, are moving to open access. I just hope funding follows, since the current model is to let the researcher somehow cover the costs. This could create a model where only the top funded groups are even able to consider publishing in the top journals (given the large cost), and where decisions on which journal to consider to submit a paper are based on the cost first instead, of journal audience or fit.

Gelation phase diagrams of colloidal rod systems measured over a large composition space
Shiqin He, Marco Caggioni, Seth Lindberg and Kelly M. Schultz
RSC Adv., 2022,12, 12902-12912

Dr. Kelly M. Schultz is an Associate Professor in the Department of Chemical and Biomolecular Engineering at Lehigh University. She obtained her B.S. in Chemical Engineering from Northeastern University in 2006 and a Ph.D. in Chemical Engineering with Professor Eric Furst from the University of Delaware in 2011 as a National Science Foundation graduate research fellow. While at Delaware, she was invited to speak in the American Chemical Society Excellence in Graduate Polymers Research Symposium and was selected as the Fraser and Shirley Russell Teaching Fellow. Following her PhD, she was a Howard Hughes Medical Institute postdoctoral research associate at the University of Colorado at Boulder working in the laboratory of Professor Kristi Anseth. As a postdoc, she was invited to participate in the Distinguished Young Scholars Summer Seminar Series at the University of Washington. She began her position as Assistant Professor at Lehigh University in 2013, was named a P.C. Rossin Assistant Professor from 2016 – 2018 and was promoted to Associate Professor in 2019. Dr. Schultz was named one of TA Instruments Distinguished Young Rheologists (2014), awarded a NSF CAREER award (2018), the Lehigh University Libsch Early Career Research Award (2019), the P.C. Rossin College of Engineering and Applied Science Excellence in Research Scholarship & Leadership (2020), a National Institutes of Health – National Institute of General Medical Sciences Maximizing Investigators’ Research Award (MIRA R35, 2022) and named the Pirkey Centennial Lecturer by the McKetta Department of Chemical Engineering at the University of Texas at Austin (2022). Dr. Schultz and her research group study emerging gel materials developed for applications from consumer products to materials that can enhance and restart wound healing. Of particular interest is the development of bulk and microrheological techniques that measure how 3D encapsulated human mesenchymal stem cells degrade and remodel synthetic hydrogel scaffolds during motility.

Could you briefly explain the focus of your article to the non-specialist (in one or two sentences only) and why it is of current interest?

This work focuses on characterizing the material properties of different formulations of a colloidal fibrous gel. These materials are used in fabric and home care products and this work provides a table where the desired material properties can be looked up eliminating trial-and-error experiments during product development.

How big an impact could your results potentially have?

This work is in collaboration with engineers at Procter & Gamble. We are working with some of their materials but also exploring new materials with similar dimensions that they are interested in using in consumer products. So there is potential for our work to inform the design of new products. To the greater scientific community, this work provides a methodology for tackling material characterization over a large formulation space, which can also have an impact.

Could you explain the motivation behind this study?

As I mentioned in the previous question, this has been a long standing collaboration with Procter & Gamble. We started working with colloidal fibers that they currently use in their fabric and home care products. Since then we have expanded the work to investigate different Fibers to determine if they can also be used as rheological modifiers. Beyond enabling the use of these materials in new products, my group is interested in developing new characterization and analysis techniques. This work uses established characterization techniques to collect data but as you can see in the presentation of the data, we aim to maximize the information we can get from a measurement and that is always a motivation behind our work.

In your opinion, what are the key design considerations for your study?

The key design consideration for our study was to systematically traverse a large formulation space experimentally. Then we wanted to find a way to present this large set of data that would enable a researcher that is working in formulations to use this as a lookup table to inform the design of their product.

Which part of the work towards this paper proved to be most challenging?

The interpretation and presentation of the data was quite challenging. We had a large amount of data and at some point you realize that the more data you have the harder it is to interpret it. Being able to organize it in a way that we could show trends and draw conclusions was really a challenge.

What aspect of your work are you most excited about at the moment?

This work is evolving to use more sustainable colloidal fibers, something both my group and our collaborators are interested in. This is really exciting since it has the potential to use a waste product in new formulations.

How has your research evolved from your first article to this particular article?

Our first article on this work was developed analysis methods to interpret microrheological data to characterize a heterogeneous colloidal gel. All of the work since that time has built upon this to give us a toolbox of characterization and analysis techniques that allows us to effectively interpret our data, even in complex systems. We have also started characterizing new colloidal gel systems, which are very exciting. Using these techniques and previous knowledge to characterize the rheology of these materials, we hope to enable their use in products.

What is the next step? What work is planned?

As mentioned previously, we are moving on to a sustainable colloid, a waste product. We are characterizing this material to see if we can modify the colloid to enable it’s use as a rheological modifier in fabric and home care products. We are really excited about this work and the direction that the project is taking.

Why did you want to publish in RSC Advances?

We thought that this was not only an interesting study of these particular materials but also a really nice way to characterize, analyze and present this type of data. The reason we chose RSC Advances was because of the wide readership. We thought getting not only the results but the technique to a wider audience would have a bigger impact.

Continuous flow Meerwein–Ponndorf–Verley reduction of HMF and furfural using basic zirconium carbonate
Henrique Magri Marçon and Julio Cezar Pastre
RSC Adv., 2022,12, 7980-7989

Julio C. Pastre obtained his PhD in 2009 under the guidance of Professor Carlos Roque D. Correia at the University of Campinas – UNICAMP. He then worked as a research scientist at Rhodia-Solvay before moving back to UNICAMP for postdoctoral studies with Professor Ronaldo A. Pilli. In 2012, he joined the group of Professor Steven V. Ley at the University of Cambridge. Two years later, Julio established his independent research group at UNICAMP and recently became an Associate Professor. In 2019, he was recognized as an ‘Emerging Investigator’ by Reaction Chemistry & Engineering and as a ‘New Talent from the Americas’ by RSC Medicinal Chemistry. Julio was chosen by the editorial boards of Synthesis, Synlett, and Synfacts as one of their ‘Thieme Chemistry Journals Awardees’ for 2023. His research interest focuses on the development of new synthetic methods in batch under microwave irradiation and under continuous flow conditions for the synthesis of platform molecules, new chemicals and APIs.

Could you briefly explain the focus of your article to the non-specialist and why it is of current interest?

In this work, we explored the valorization of two biobased chemicals (HMF and furfural) that can, for example, be used in the synthesis of polymers and are important intermediates to reduce our fossil-dependency and mitigate environmental issues.

How big an impact could your results potentially have?

By designing new synthetic methods that take full advantage of the capabilities of new enabling technologies, one will inevitably end up with greener, cleaner processes.

Could you explain the motivation behind this study?

We are keen to develop new processes for the synthesis of high value-added compounds from biomass derivatives in continuous flow regime.

In your opinion, what are the key design considerations for your study?

Our group has already identified continuous flow processing as a fundamental technology for the valorization of biomass derivatives, so that any designed methods can be rapidly scaled to manufacture. Moreover, many of the principles of Green Chemistry can be met by embracing new technologies that are inherently cleaner when compared to the traditional approaches.

Which part of the work towards this paper proved to be most challenging?

Although the process concerns just a reduction of an aldehyde, the obtention of a selective process is quite challenging since several competitive reactions can take place leading, for example, to the formation of humins.

What aspect of your work are you most excited about at the moment?

We are excited about the impact that flow chemistry can have in the valorization of biomass considering its key advantages, such as better control of heat and mass transfer, improved mixing, and safety profile.

How has your research evolved from your first article to this particular article?

Most of our previous works were done under homogeneous conditions. The use of heterogeneous catalysts in a fixed-bed reactor represents a good evolution in view of catalyst recycling, product separation and throughput.

What is the next step? What work is planned?

We want to apply these findings to other biobased chemicals and develop an integrated approach for the valorization of these materials.

Why did you want to publish in RSC Advances?

I’m a reader of RSC Advances, which publishes high impact research. So, it is a great pleasure to have our work published in such a prestigious journal.

What are your thoughts on open access publishing?

I believe open access publishing is going to be dominant soon since it gives access to a broader community and “democratize” science.
