Happy Chinese New Year!

Happy Chinese New Year to all our authors, reviewers and readers from all of us at Chemical Science!

To celebrate the year of the tiger we have put together a collection highlighting our most popular articles from the past year from our Chinese authors, as well as a selection of infographics accompanying some of these papers, which you can find below.

Chemical Science Reviewer Spotlight – January

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 Nan-Nan Deng, Ashraf Brik, Goran Angelovski and Jiang Weng. We asked our reviewers a few questions about what they enjoy about reviewing, and their thoughts on how to provide a useful review.

Nan-Nan Deng, Shanghai Jiao Tong University. Nannan’s research focuses on bottom-up construction of artificial cells and their behaviors using microfluidics.

Ashraf Brik, Technion – Israel Institute of Technology. My research focuses on using chemical approaches to shed light on the function of proteins—the molecules that carry most cellular tasks, studying how malfunction in their role can lead to disease development and find solutions to such defects for drug development.

Goran Angelovski, Chinese Academy of Science. My research is focused on the design, preparation, and validation of bioresponsive MRI probes that are sensitive to calcium ions or neurotransmitters. These are intended to serve as markers for the functional molecular imaging applications, particularly the neuroimaging.

Jiang Weng, Sun Yat-sen University. Jiang’s research focuses on developing efficient methods for the synthesis of functional small molecules. Currently, we are involved in the areas of asymmetric catalysis and SuFEx click chemistry, and their further application in medicinal chemistry.

 

What do you enjoy most about reviewing?

Ashraf Brik: Being able to review for excellent journals is a privilege! This is because you not only being among the first people to see the emergence of great science but also being part in shaping it. With this also comes the responsibility of being very rigorous and updated of your particular research area and in science general.   

Goran Angelovski: I like observing the evolution of the manuscript from its initial version, to being published in the final form. I enjoy the exchange of arguments and a constructive communication between the reviewers and authors, even if strong criticism has been expressed.

What are you looking for in a paper that you can recommend for acceptance in Chemical Science?

Jiang Weng: I think sufficient novelty and/or significance is the most essential element for the acceptance of a manuscript. In addition, telling a science story clearly and concisely is also very important.

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

Goran Angelovski: Be critical but fair. Do not focus on the final recommendation to accept or reject the manuscript, but how you can help identifying its shortcomings, eventual flaws, or parts where it may become even better. Focus on your role as the evaluator and how/if you can help the work submitted for publication become even better, in the submitted journal or elsewhere. Always have in mind that your role is the assessment of the work under the review, not the decision making. Leave the latter part to the editor.

What encouraged you to review for Chemical Science?

Nan-Nan Deng: Chemical Science is a journal that I usually glance over on-line for finding good papers in my fields.  I have read many great papers from the journal, and am glad to be a reviewer of it.

 

Tune in next month to meet our next group of #ChemSciReviewers!

How can cooling rate define the nature of nano-structures formed using block copolymers?

Block copolymers (BCPs) consist of amphiphilic molecules that can self-assemble in selective solvents and generate various types of nano- and micro-dimensional structures. The unique self-assembly process is low-cost and relatively straight forward in solution phase.  The final structures have morphological diversity and complexity.  These self-assembled structures have been widely used in various applications such as drug delivery, catalysis, and water purification. The self-assembly process follows a heating step for dissolution of all the components and a subsequent cooling step. Both the steps and the parameters are vital for final structural characteristics of the assembled structures. A group of scientists from two esteemed universities in Canada recently studied the effects of rate of cooling in the self-assembly process.

Schematic representation of how cooling rate can change the morphology of formed micellar structures using PFS BCP and homopolymers

The authors used a systematic approach to explain the influence of cooling rate on micelle morphologies for a series of PFS based BCPs. The cooling rate greatly influences the size and the shape of colloidal structures. Rapid cooling increases branching and opens a new avenue to manipulate micelle morphologies. The study finds that rapid cooling reduces crystallinity, as polymer chains do not have enough time to pack in ordered structures.

The authors standardized sample preparation protocol and then varied the cooling times, with quick cooling of 2.5 min producing flower like structures and median cooling time of 50 mins leading to the same structural features with larger size. Co-self-assembly of homopolymer BCP mixtures with variable cooling rate also shows that quick cooling generates uniform sized branched micellar structures with elongated central platelets whereas slow cooling led to a long single fiber with a dark circle platelet in the centre.

With several examples and optimization conditions, the effect of cooling in the formation of self-assembled micellar structures has been evaluated. The main outcome of this study is that the cooling rate is another parameter to manipulate crystallization-driven self-assembly and to control micelle morphologies. There exists a lot of possibilities to use the findings and apply them to generate BCPs with a crystallizable block with important optical or electronic properties.
