March’s LabTalks in JPCM

March was a busy time for LabTalks on JPCM with a total of 11 high quality papers being highlighted last month. LabTalks are accompanying news-style articles written by authors in an accessible way to help readers understand the results and conclusions of their work. To give you all a taste of the broad and diverse topics we cover, below are just some of the LabTalks published last month.

Why are transcription factors so large?
Transcription factors play a key role in the very important biological process of converting DNA to RNA. In this LabTalk, Maeshima et al explain their novel theory as to why transcription factors differ so much in size. Their paper forms part of a special issue on the physics of chromatin, covering both modelling and experimental work from the microscale up to macro-molecules. The issue was guest edited by Ralf Everaers and Helmut Schiessel.

Catalytic suboxide formation on a titanium dioxide surface
Migrating transition-metal atoms are decelerated on a reactive TiO2 surface to be stabilized by spontaneous oxidation. The authors of the LabTalk explain why their results affect the understanding of TiO2 during thin-film fabrication.
Based on: Shindo et al 2015 J. Phys.: Condens. Matter 27 122001

Magnetic properties and electronic structure of Mn-Ni-Ga magnetic shape memory alloys
The authors explain the effects of chemical disorder and anti-site defects on the magnetic and electronic properties of intermetallic shape memory alloys.
Based on: D’Souza et al 2014 J. Phys.: Condens. Matter 27 506001

Hydroxamate linker predicted to improve the efficiency of Fe(II)-polypyridine sensitized solar cells
Part of our special issue on the theory of solar energy materials, Bowman et al talk about their work on making the interfacial electron transfer process more efficient by altering the idenity of anchoring groups.
Based on: Bowman et al 2015 J. Phys.: Condens. Matter 27 134205

Unveiling surface modes of superconducting topological insulators
Hao et al uncover unexpected surface modes of superconducting topological insulators and discuss their new theory in this latest LabTalk. They also propose follow up work and how they continue to strive to understand the topological nature of surface bound states.
