Insights into the Photocatalytic Arene Bromination Enabled by Cs2AgBiBr6 Microparticles

Chemistry – A European Journal, EarlyView.
A sustainable photocatalytic bromination of electron‐rich arenes is enabled by low‐toxicity Cs2AgBiBr6 double‐perovskite microparticles using HBr as an atom‐economical bromine source. Surface‐derived bromine radicals drive highly selective mono‐bromination under mild conditions.

UHV - Kupferfallen

, 1961
Einleitung: Im Jahre 1953 gab Alpert eine Kupferfolienfalle für Öldiffusionspumpsysteme an, mit der es möglich ist, das Endvakuum für eineige Wochen unter 10-9 Torr zu halten. Nach dieser stay-down-Zeit steigt der Druck ziemlich schnell auf einige 10-8 Torr, den "Dampfdruck" des Treibmittels, an.

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, EarlyView.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

Surface and Interface Analysis, EarlyView.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...
