Exceptional poster prizes now available for ISACS11 (Challenges in Chemical Biology)

We are delighted to announce that the RSC and Roche have teamed up to offer two exceptional PhD poster prizes for the best contributions at Challenges in Chemical Biology (ISACS11).

The winners will be rewarded with an all-expenses paid trip to Shanghai, China later this year where they will attend a two-day RSC-Roche symposium and be given the unique opportunity to present their work to Roche staff along with other leading PhD students.

As this exciting news has only just been publicised we have decided to extend the poster abstract submission deadline to Wednesday 22 May 2013.

Be sure to take advantage of the excellent opportunity to showcase your work to a truly global audience at ISACS11 and have a chance to win a trip to China by submitting a poster abstract today.

Excellent visibility for your research

Chemical Science is dedicated to publishing findings of exceptional significance from across the chemical sciences. We want our authors’ research to get the visibility and recognition it deserves.   

The graph below shows the number of citations to articles published in 2012 in Chemical Science and other leading general chemistry journals.    

It’s clear to see from this data that articles in Chemical Science are less likely to receive no citations and after just a few months of publication articles will be highly cited – 30% of 2012 Chemical Science articles have already received 5 or more citations.  

Publishing your research in Chemical Science means your article will have excellent visibility and will be read and cited quickly by your colleagues.

Robotic ribosome-mimicking rotaxanes featured on Chemistry World

Congratulations to our Chemical Science Associate Editor, Professor David A Leigh, for recently being featured on Chemistry World for his latest work in using artificial molecular machines to mimic ribosomes in assembling peptides.  These exciting new ‘robot ribosomes’ designed and studied by Dave’s research group have been gaining more and more attention, also having been highlighted in Chemistry and Engineering News (C&EN).

You can also read Dave’s latest Chem Soc Rev Tutorial Review on template synthesis of molecular knots, and his 2012 Chem Comm paper on half-rotation in a kinetically locked [2]catenane.

Dave is an expert in supramolecular chemistry, focussing on the development of new methods for the synthesis of catenanes and rotaxanes, and on experimental synthetic molecular machine design.

Are you working in supramolecular chemistry, experimental molecular machines, or related fields?  Submit your top-notch, high-impact articles to Dave’s Chemical Science editorial office today!

Harnessing thermal fluctuations for purposeful activities: the manipulation of single micro-swimmers by adaptive photon nudging

US scientists have found a way to control the direction of microscopic swimming robots using lasers. This is the first time that anyone has used a method like this to control a microscale particle in solution, they say.

Haw Yang at Princeton University and his colleagues used a polystyrene particle, with one half of its sphere coated in gold, as the swimmer. This type of particle is known as a Janus particle as it has two ‘faces’ that show different physical properties. The team used these properties to manipulate its direction. The Janus particle moves randomly in a liquid via Brownian motion, and when the particle is facing the right direction, the team uses a laser to give it a nudge forward.

Microswimmer

The researchers found that the laser propels the Janus particle by heating up the gold half of the sphere, which propels it forward. The polystyrene half doesn’t react to the laser as the laser essentially passes through it. The team used short bursts of the laser, and if the particle went off target, they stopped nudging it until it came back round to the right position.

C-H activation: an article collection

C-H ActivationOne of the simplest and most utilised chemical reactions is the burning of hydrocarbons and while combustion is an excellent way to exploit the energy content of this naturally occurring resource, there is a lot more we can do with the ‘inert’ C-H bond.

C-H activation allows us to convert cheaper hydrocarbon starting materials into more valuable and versatile products; leading to the development of a wide range of reagents and catalysts that activate C-H bonds. To keep you up to date with the latest developments in the field we have created this article collection, where all articles are free to download until 15th December.

Fluorescence, camera, action

Fluorescence responses can be analysed using digital photography instead of spectroscopy, say scientists in Germany. The technology could eventually be integrated into smart phones.

Uwe Bunz and his colleagues from the University of Heidelberg used digital photography to study the optical changes occurring when different pyridine-substituted cruciform (cross-conjugated) fluorophores (XF) were subjected to protonation. They protonated the nitrogen on the pyridine and observed the colour changes of the XFs in the presence of carboxylic acids.

The team extracted data from the photographs by transforming the red, green and blue (RGB) values into numerical values, a process that helps define the colour and removes brightness information. ‘The method is quick and inexpensive, and large data quantities can be stored and acquired in seconds,’ says Bunz.
