Vote for Chemical Science in the ScholarOne Journal Triathlon!

Vote now for Chemical Science!

We’re very proud to announce that Chemical Science has been nominated as one of the journals competing in this year’s ScholarOne Journal Triathlon, for the category ‘Swimming/Agility.’ This first stage of the triathlon, according to ScholarOne, is all about “how quickly and easily a journal is able to validate that they are accepting the right papers for their journal.”

In her nomination piece, Senior Publishing Editor Philippa Ross justifies why we think Chemical Science particularly excels in this category:

  • The introduction of the Edge article, a new article type which allows authors to present a novel piece of scientific research in an exciting succinct format with no page restrictions.
  • 17 world-leading scientists recruited by the Editor-in-Chief as Associate Editors whose expertise covers the breadth of the chemical sciences, and who act as gatekeepers of the science, ensuring that only the very best articles are accepted after peer review. The Associate Editors also raise the visibility of the journal internationally, which is vital in generating high quality submissions.
  • Highly talented and experienced professional editors, all with a broad range of scientific and publishing expertise, who make an initial assessment of all submissions received and decide whether a manuscript should be rejected without peer review or forwarded to an Associate Editor for consideration.
  • For each submission, the professional editors followed by Associate Editors are required to ask themselves a series of challenging questions around the novelty, significance, impact and originality of the research article. This triple layer of peer review helps us achieve our goal of only publishing exceptional research.

As a result of this rigorous process, only 10% of submitted Edge articles meet the exceptionally high standards for acceptance and publication in Chemical Science.

With our 2012 impact factor having risen to an impressive 8.314 and having been awarded as the Best New Journal 2011 by the Association of Learned and Professional Society Publishers (ALPSP), we know that we truly are accepting only the best and most suitable papers for Chemical Science.

S1 Journal Triathlon

“This all-virtual tournament,” according to the ScholarOne Journal Triathlon webpage, “(which was) created to recognise the innovative work of scholarly journals, will allow a journal to compete with its peers in divisions of scholarly agility, efficiency, and endurance—the attributes of a true journal champion.”

We think we’ve got the agility to be the best, and we hope you do, too!

Vote now for Chemical Science!

Voting now underway– spread the word! Voting for this category is open to the general public till 7th October 2013.

Half-mustard gas blues

In the presence of half mustard, the dithiol does not react with the squaraine dye so the dye’s blue colour is visible

Scientists in the US are trying to develop a new detection system for the chemical warfare agent mustard gas

There is no antidote to mustard gas, which burns the skin, eyes and respiratory system. Victims not killed by an attack are left severely incapacitated. It is an environmentally persistent chemical and its cruel effects can take around 12 hours to take hold. A cheap and simple sensor to alert civilians and emergency responders to its presence is obviously desirable. 

Eric Anslyn and Vinod Kumar at the University of Texas at Austin are getting closer to such a system. With the knowledge that chlorine atoms in mustard gas will readily react with good nucleophiles like thiols, they have designed a dithiol and squaraine dye system to give a clear colour change in the presence of the mustard gas simulant 2-chloroethyl ethyl sulfide, also known as half mustard.

Crushing the insolubility of graphite with solid-state Diels-Alder reactions

Researchers from South Korea have reported the chemical modification of graphene nanoplatelets using a solid-state technique, which has led to a dramatic improvement in their solubility in a wide variety of solvents.

(a) Mechanochemically driven solid-state Diels–Alder reaction between active carbon species by ball-milling in the presence of maleic anhydride (MA) or maleimide (MI). SEM images: (b) pristine graphite, (c) MA-GnPs, (d) MI-GnPs.

Graphene, a single-layer two-dimensional sheet of aromatic carbon atoms, has attracted a lot of interest since the realization of its unique electric, optical, mechanical and thermal properties. These properties can be further exploited and improved upon the functionalization, either covalently or non-covalently, of the graphene surface. The catch-22 is that unfunctionalized graphene is inherently insoluble, making it difficult to modify chemically, but its properties can typically be improved solely through chemical modification. As a result, much work has been carried out to develop methods of facilitating the covalent modification of graphene – in higher yields and more easily than currently possible.

Jong-Beom Baek and his team at the Ulsan National Institute of Science and Technology (UNIST) have achieved such a feat by increasing the solubility of graphene nanoparticles using, for the first time, a dry ball-milling reaction. Using Diels-Alder [4+2] cycloaddition reactions between graphene nanoplatelets (derived from the ball-milling of graphite) and either maleic anhydride or maleimide, O and N atoms were selectively introduced to the edges of graphene nanoplatelets in reasonable yields. As a result, the nanoplatelets showed good dispersability in both protic and polar aprotic solvents, including in neutral water. This is a significant achievement, as the Diels-Alder reaction allows for a large range of functional groups to be attached to the graphene edges and offers a general method for the chemical modification of graphene.

Handcuff catenanes

Scientists in the US have successfully used a template directed protocol to synthesise two topological isomers of a handcuff catenane. Handcuff catenanes are mechanically interlocked molecules where two covalently bound rings, called the ditopic host, are interlocked by a third ring threaded through both rings of the ditopic host. Only three other mechanically interlocked molecules with the handcuff topology have been reported before – they are very difficult to synthesise.

Previous handcuff catenanes have all been achiral and have only demonstrated one way to thread the third ring through the diptopic host. The handcuff catenane made by Fraser Stoddart and colleagues at Northwestern University has two distinctive topologies – it is impossible for one to be converted into the other, unless covalent bonds are broken and then re-made. The stereochemistry demonstrated by Stoddart’s handcuff catenanes is interesting because as well as being topologically chiral they also display Euclidian chirality.

A template directed synthesis between the π-electron-rich bis-1,5-dioxynaphtho[50]crown-14 and the precursors of two fused π-electron-deficient cyclobis(paraquat-p-phenylene) cyclophanes was used to make the topologically complex molecules. The handcuff catenanes could have future applications in molecular switches.

5 minutes with Ben Davis, Chemical Science Associate Editor

Ben Davis is Professor of Chemistry at the University of Oxford, where he is a Fellow and Tutor in Organic Chemistry at Pembroke CollegeHis group’s research explores the exciting and rapidly expanding interface between chemistry and biology, with an emphasis on carbohydrates and proteins.

An Editorial Advisory Board member of Chemical Science since its launch in 2010, Davis now serves as one of the journal’s Associate Editors, handling submissions in chemical biology.

What excites you most about chemical biology?

I think it’s probably the unique position chemistry is now in, to be able to address the really fundamental questions about how biology works at a molecular level.  Not just static stuff or indirect, but a combination of strategies that will unpick what you might call mechanistic biology.  We’re at a real turning point in science, where biology now needs to be that detailed, and chemistry has now developed the tools to deliver that detail – the two fields are genuinely starting to shake hands properly.

If you could go back in time, which scientist would you most like to meet or work with?

They’re all so very different.  Probably Boyle.  Because he was mad, brilliantly mad, completely unfettered by convention.  Very creative.

What’s the best advice a mentor or supervisor has ever given you?

Probably the best advice I’ve ever had was from Brian Clough, who told me I should “smile more.”  But then I don’t think you can really count him as a mentor.  Probably the best mentorship advice I’ve ever had was that you need to pick interesting, big problems.  Life is short, so pick big stuff.  Pick things that matter and that excite you, and do it through passion, and don’t waste time worrying about what other people will do, and what other people might take from you.  If you don’t have enough ideas to keep moving forwards and testing fresh things, no matter what other people are doing, then you are probably in the wrong job.  It’s not about the individuals, it’s about the science.

What do you enjoy doing when you’re not in the lab, teaching, writing, or handling Chem Sci papers?

I row, basically.  Indoor/outdoor, whenever I can, however I can.  Pembroke College Boat Club (Head of the River) is a near utopian state.

If you were to be shipwrecked on a deserted island, which item currently in your pocket would be most useful to you?

I haven’t got anything in my pockets.  I have this habit of emptying my pockets when I go into a room – frees the soul.  I’m not really that dependent on the stuff in my pockets, to be honest (and I hate pod-zombies).  So, no, nothing really.

What makes a Chem Sci Edge article HOT?

Innovation.  Creativity.  Difference.

Describe Chemical Science in three words.

Challenging current chemistry.  I’d say, Chemical Science is making people think about the way chemistry is researched and published, putting out stuff that’s different and trying to break down the traditional routes of dissemination whilst maintaining the ethics of proper, rigorous peer review by experts.  Its freshness is powerful, and this is generating a powerful and unique group of authors, reviewers and readers, I think.

Your personal message to Chem Sci authors and readers?

What I’d love to be able to say to authors is that they should think really carefully about how they write papers and where they put those papers.  In an era when the value of publication is in danger of being eroded, it’s probably more important, rather than less important, to write quality papers and put them into a journal that’s going to mean something long-term, has a good audience, and has – impact is the wrong word – but has something that connects with people that matter (now and in the future).

There’s this increasing trend for not peer-reviewing, and not doing things with rigour, things just being posted up and being reviewed in real-time, and all of this stuff which is undermining the quality of science we publish.  We seem to have forgotten that over 350 years ago, we developed a sensible and intelligent mechanism of trying to ensure that quality wins out.  Expert peer review, in my experience, always improves the science if all involved are sufficiently open-minded and hungry to do better.  The idea of creating mounds of poorly evaluated data and analyses without any true advice or moderation is madness (and something we turned our back on as a community in the 17th century).  True scholars want to get better and do better by getting advice, not getting their stuff out at any cost (the latter are just blaggers or advertisers).

This quality is what will really matter in 50 years’ time, when we’re all probably dead and buried (at least some of us) – then the legacy will be the paper, and only the paper, and the science that’s in it.

And so it needs to be somewhere that’s going to have longevity and impact.  It’s even more important to put it somewhere that is rigorous in its process, that makes you do better, that tests you and pushes you to create better work.  Then you create something that you’re proud of, and then the paper will speak for itself; whereas if you go to journals that will just let you get stuff in (slop buckets), then it’s almost pointless.

Which means– publish less, but publish better.

Ben Davis and our dynamic international team of Associate Editors make direct decisions on the content of Chemical Science and actively drive its scientific development – submit your best and most innovative work to any of their Editorial Offices.
