Chemical Science Reviewer Spotlight – October 2022

To further thank and recognise the support from our excellent reviewer community, we are highlighting reviewers who have provided exceptional support to the journal over the past year.

This month, we’ll be highlighting Wade Petersen, Pachaiyappan Rajamalli, Shikha Dhiman and Daniel Gryko. We asked our reviewers a few questions about what they enjoy about reviewing, and their thoughts on how to provide a useful review.

Wade Petersen, University of Cape Town. Dr. Petersen’s work aims to develop low-cost chemical synthesis methods for accessing biologically important heterocycles.

 

Pachaiyappan Rajamalli, Indian Institute of Science, Bangalore. Pachaiyappan works on organic electronics, mainly focusing on the development of organic functional materials for organic light-emitting diodes.

 

Shikha Dhiman, Eindhoven University of Technology. Shikha investigates the structure-function-dynamics relationship of supramolecular polymers utilising advanced techniques such as super-resolution imaging to optimise their potential applications.

 

Daniel Gryko, Institute of Organic Chemistry – Polish Academy of Sciences. Professor Gryko is trying to discover novel functional dyes possessing better photophysical properties compared to existing ones. They could find applications in organic optoelectronics including organic light-emitting diodes.

 

 

What encouraged you to review for Chemical Science?

Shikha Dhiman: Chemical Science focuses on high-quality, multidisciplinary research, and reviewing is one component of my service to the scientific community in assessing and improving the quality of articles.

Daniel Gryko: The exceptionally high level of science which is published regularly in Chemical Science.

 

What do you enjoy most about reviewing?

Wade Petersen: I enjoy getting a ’sneak peak’ into the latest work by the scientific community as well as playing a small part in improving the manuscript (where possible) by offering some suggestions. It is also wonderful to see authors taking on this advice in the published version of the manuscript. It certainly makes your effort worthwhile and is energising to want to review again.

 

What advice would you give a first-time author looking to maximise their chances of successful peer review?

Pachaiyappan Rajamalli: Your work should be unique, and good clarity in your writing will enhance the success rate. 

Daniel Gryko: First of all make sure you Conclusions section contains real conclusions rather than another rephrased version of your abstract. Secondly, the manuscript has to contain comparisons with the state of the art. This is especially true for synthetic manuscripts and papers focused on functional dyes. Last, but definitely not least, see if you can summarize the novelty in two sentences only. That truly helps with self-evaluation of the manuscript.

 

Do you have any advice to our readers seeking publication in Chemical Science on what makes a good paper?

Shikha Dhiman: Readers are drawn in by a clear and intriguing abstract that highlights the substantial contribution made along with self-explanatory figures. Following that, the contribution, which is supported by properly conducted experiments, appropriately interpreted data, and an essential outlook for the reader, completes a good story.

 

What would you recommend to new reviewers to ensure their report is helpful?

Pachaiyappan Rajamalli: The report should clearly indicate your decision whether to accept or reject it. Check for the novelty of the work, if the work is novel, please give your input to improve the manuscript.

 

What has been your biggest learning point from reviewing?

Wade Petersen: The true value that you can add to authors in improving their work for publication. It is easy to simply say ’no’. But offering a detailed review on how the work can be improved for successful review really is a great service to the both the authors and to the community as a whole.

Highlighting our #MyFirstChemSci

Recently, Chemical Science author Professor E. W. Bert Meijer (Eindhoven University of Technology, The Netherlands) sent us a video which showcased his first paper published in Chemical Science ‘Macrocyclization of enzyme-based supramolecular polymers, Chem. Sci., 2010,1, 79-88’ (https://doi.org/10.1039/C0SC00108B).

His paper was also the first paper published online in Chemical Science when the journal launched in 2010.

 

Thanks to Professor Meijer for sharing the video with us!

Multifunctional materials from tuneable nanoparticles

Metal-organic framework (MOF) nanoparticles combine with carbon microfibres to make large-scale materials with many possible applications

Assembling very small-scale nanoparticles into larger structures, commonly known as macroarchitectures, offers opportunities to exploit the nanoparticles’ unique chemical and physical properties while they are embodied within much larger components. Researchers in China, Australia and Japan developed a method that readily combines nanoparticles called metal-organic frameworks (MOFs) and micron-sized carbon fibres into versatile macroarchitecture materials.

The team, at Nanjing University of Science and Technology, China, the University of Queensland, Australia and the JST-ERATO Yamauchi Materials Space Tectonics Project, Japan, report their innovation in an article in the open access journal Chemical Science.

“While retaining the characteristics of the nanomaterial they are built from, our macroarchitectures also add in many new kinds of features such as high surface areas, high mechanical strength and low density,” says Professor Yusuke Yamauchi of the University of Queensland group.

From nano to macro in a simpler process

The manufacturing procedure begins with the MOF nanoparticles, which consist of metal ions or metallic clusters connected by organic (carbon-based) linker groups. Varying the metallic and organic components can generate a wide variety of MOFs with different chemical and physical properties.

The MOFs are then combined with hollow carbon-based fibres to form much larger centimetre-scale aerogels, which are highly porous and have extremely low densities. These unique materials can be generated in a variety of desired shapes, and possess great elasticity and compressibility, combined with chemical stability and physical strength.

Existing methods for making similar materials are problematic as their assembly usually yields products with relatively poor mechanical properties, and requires the use of adhesives or templates which have to be removed in additional steps. In contrast, the new method causes ‘zeolitic imidazolate framework (ZIF-8)-polyacrylonitrile nanofibers’ to directly assemble into centimetre-sized aerogels with controllable shapes and tuneable properties.

“The materials integrate the properties of one-dimensional nanofibers and three-dimensional carbon aerogels,” says Yamauchi.

Many possible uses

The macroarchitectures composed of three-dimensional porous interconnected networks could have commercial applications in many fields. The initial key to unlocking a wide range of practical uses is to design MOF structures that will achieve specific functions in each resulting aerogel. These could involve adsorbing specific chemicals into the pores of the final structure, catalysing chemical processes, or converting and storing energy, including electrical energy within capacitors.

Laboratory-scale trials have already demonstrated that some of the porous structures – which the researchers describe as “somewhat resembling that of a loofah sponge” – have impressive oil-retaining properties when exposed to mixtures of oil and water. This effect could be exploited to clean oil from polluted water. One version of the materials also has catalytic properties that could be useful for chemically degrading a variety of other pollutants.

The aerogels also have an impressive ability to absorb light and convert it into heat at high efficiency, which could be used to prepare drinkable water by desalinating seawater. “We believe that in the future our materials could be used for several large-scale and cost-effective water purification applications,” says Yamauchi.

The researchers now aim to develop the potential for moving from laboratory scale proof-of-concept demonstrations to commercially useful applications.

Chemical Science is open and free for both readers and authors.
