As easy as TT

Scientists’ discovery that π electron repulsion is more important than previously thought might change our understanding of conjugation. The effect is behind peculiar irregularities in bond lengths and resonance energies of conjugated molecules that our textbooks cannot explain.

Conjugated molecules like 1,3-pentadiene have π electrons that are delocalised across several bonds. Conjugation lowers a molecule’s overall energy and makes it more stable. However, a few years ago, researchers from Long Island University, US, claimed that conjugation could actually destabilise some molecules. They calculated cyanogen (NC–CN) to be less stable than its non-conjugated analogue ethylenediamine (H2NCH2–CH2NH2). Many researchers have tried to disprove this, but so far, no one has been able to give a simple explanation for these apparently counterintuitive results.

Professor Shankar Balasubramanian gives the opening talk at ISACS 16

From 15-18th June, the lecture theatre at ETH Zurich was almost full as delegates from 26 different countries gathered to hear the latest research in the field of Chemical Biology as we continued our series of International Symposia on Advancing the Chemical Sciences.

Across the 4 days of the conference we were treated to a diverse range of topics, from the very beginnings of life as we know it with John Sutherland to the latest diagnostic markers in various stages of clinical trials with Annette Beck-Sickinger, Yasuteru Urano and others. We also enjoyed various contributions on the latest synthetic developments to smooth the process of discoveries and heard about the latest natural product being identified and their potential applications.

We were delighted to have an enthusiatic participation in our “flash” poster presentations (just three minutes each) and overall around 80 posters were displayed and discussed during the event.

The Chemical Science sponsored poster prize was won by Eugenio Indrigo (University of Edinburgh) for his poster on “Palladium mediated chemistry in living cells, while the Chemistry World poster prize (and associated mug!) was won by Oliver ThornSeshold (Ludwig-Maximilians-Universität, Munich). Congratulations to them both!

The final talk of the meeting was the 2014 Chem Soc Rev Emerging Investigator lecture, given by Prof. Peng Chen (Peking University) entitled “Exogenous chemistry for intracellular protein manipulations” and was an impressive overview of the exciting work being done in his lab.

We look forward to announcing the next installment of the ISACS conference series on the theme of Challenges in Chemical Biology in the near future…

Daniel Nocera – our new Chemical Science Editor-in-Chief

We are delighted to announce Professor Daniel Nocera as the new Editor-in-Chief of Chemical Science. Daniel Nocera, the Patterson Rockwood Professor of Energy at Harvard University, has a diverse research programme and is recognised, internationally, as a pioneer and leading expert in the field of solar energy conversion.

Professor Nocera’s group has recently accomplished a solar fuels process that captures many of the elements of photosynthesis – he has now translated this science to produce the artificial leaf. This exciting discovery sets the stage for a storage mechanism for the distributed deployment of solar energy.

As we thank Professor David MacMillan for his valuable contributions to Chemical Science since its launch in 2010, we extend a warm welcome to Professor Nocera as he leads the journal towards continued success and excellence.

Professor Nocera joins us in inviting you to read Chemical Science’s first Open Access articles in Issue 1 for 2015 – one hundred cutting-edge articles showcasing exceptional research across the chemical sciences. For a limited time, these have been gathered under broad subject areas to show significant breakthroughs in each field:

Analytical Chemistry

Chemical Biology and Medicinal Chemistry

Organic Chemistry

Catalysis

Energy and Physical Chemistry

Materials

Nanoscience

Inorganic Chemistry

Chemical Science is the Royal Society of Chemistry’s flagship journal, publishing research articles of exceptional significance and high-impact reviews from across the chemical sciences. The journal’s latest (2013) Impact Factor is 8.6. Research in Chemical Science is not only of the highest quality but also has excellent visibility; this is reflected in our latest citation profile.

This special issue, guest edited by Professor Michel Orrit, Professor Taekjip Ha and Professor Vahid Sandoghdar, combines tutorial reviews with review articles to illustrate the power and versatility of single-molecule optical techniques

Additionally, don’t miss out our upcoming Faraday Discussion on Single Molecule Microscopy and Spectroscopy during the 14-16 September 2015. We look forward to welcoming you to London for this Faraday Discussion.

Abstract submission is now open, so take advantage of this excellent opportunity to showcase your latest research alongside leading scientists from across the globe. Don’t leave it too late – the deadline for oral abstracts is 8 December 2014.

Themes will include:
– Quantum optics and plasmonics
– Probes and sensors for molecular biophysics
– Superresolution and imaging of soft and biological matter
