Nobel Prize in Chemistry 2014

The prestigious Nobel Prize in Chemistry 2014 was awarded jointly to Eric Betzig, Stefan W. Hell and William E. Moerner for their outstanding contributions to advancing single molecule spectroscopy. Many congratulations to all of them!

To mark this special occasion, we would like to remember Moerner’s latest publication in Chemical Science. Take another look at his exceptional minireview on single-molecule spectroscopy. To access the full article, download a copy for free* by clicking the link below:

Single-molecule spectroscopy of photosynthetic proteins in solution
Gabriela S. Schlau-Cohen, Samuel Bockenhauer, Quan Wangac and W. E. Moerner
DOI: 10.1039/C4SC00582A

The Chemical Science team would like to take this opportunity to congratulate Prof. Moerner on this fantastic achievement.

Single-molecule optical spectroscopy is the topic of one of our very successful Chem. Soc. Rev. themed issues, aimed to sample a number of recent conceptual and methodic inroads as well as applications in single-molecule science.

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
– Nonlinear optics and coherence in biophysics

It is our pleasure to announce that two of the Nobel laureates will be with us during the event. Prof. Moerner has agreed to be our opening lecturer and Prof. Hell will be responsible for the closing remarks of this exciting Faraday Discussion. Check the programme and the complete list of speakers here.

Through the looking glass with switchable mirrors

Scientists in South Korea have developed a reversible electrochemical mirror (REM) that can switch between a transparent and reflective state, and remain reflective for up to two hours without external electrical power. Such mirrors could be used in smart windows to control lighting and reduce cooling costs for buildings.

The REM, developed by the group of Eunkyoung Kim at Yonsei University, consists of a thin layer of silver-containing electrolyte sandwiched between two transparent electrode panes…

Dangling bonds induce ferromagnetism in graphitic carbon nitride

Researchers in China have achieved ferromagnetism in graphitic carbon nitride, g-C3N4, by introducing hydrogen dangling bonds into its two-dimensional structure, making the material suitable for spintronic devices.

Spintronics exploits the intrinsic spin of electrons and their associated magnetic moments and charges to make solid-state devices such as storage media and sensors. Generally, the materials used to make these devices are ferromagnetic, that is, they form permanent magnets. Ultrathin 2D nanosheets can be used to construct such devices because they exhibit spin ordering within their structures.

Mirror peptides hitch a lift into the cell

Scientists in the US have developed a method for successfully transporting chemotherapeutic d-peptides into the cell cytosol.

D-peptides – also known as mirror peptides, as their constituent amino acid building blocks are mirror images of the naturally occurring l-amino acids – have been an intriguing target in drug development for many years. Their unnatural stereochemistry results in high resistance to proteolytic degradation as intracellular enzymes are unable to act upon them – usually a major pathway for the destruction and removal of ‘foreign’ peptides, including those intended as therapeutic agents, in cells. However, transporting these molecules across cell membranes has been a significant barrier to their potential application.
