The Acidity of Individual Atoms - Breakthrough at TU Wien
Researchers at the Institute of Applied Physics at TU Wien can now determine the proton affinity of different surface sites of indium oxide with atomic precision. In a recently published Nature paper, they probed the strength of the hydrogen bonds at the surface sites of indium oxide with the tip of a non-contact atomic force microscope and found quantitative agreement with density functional theory calculations.

Photodriven Transient Picosecond Top‐Layer Semiconductor to Metal Phase‐Transition in p‐Doped Molybdenum Disulfide
In this work, Nomi L A Sorgenfrei et al. establish how visible light itself can create a transient metallic top layer on bulk crystalline p‐doped 2H‐MoS2. Electron–hole pairs created by optical excitation separate in the surface band bending region of p‐doped semiconducting 2H‐MoS2. This causes a transient accumulation of electrons in the surface region, driving the top‐layer within several picoseconds from the p‐doped semiconducting 2H‐MoS2 into a sheet of metallic 1T‐MoS2 at a remarkably low optical fluence threshold. This mechanism has significant implications on how optically illuminated MoS2 surfaces behave.

Researcher Spotlight: Atsushi Ogura
High Energy X-rays a Vital Tool to Probe Within Materials
Interfaces between materials play a vital role in many areas, from electronics to artificial blood vessels. Professor Atsushi Ogura at Meiji University in Tokyo, Japan is at the cutting edge of the study of interfaces buried within materials. A better understanding of these buried interfaces may lead to more efficient solar cells and batteries, artificial bone, more efficient electronic devices, and many other applications.
