Machine Learning Accelerated Computational Design of Bio‐Inspired Catalysts in the Nitrogen Reduction Reaction

Advanced Materials, EarlyView.
We introduce a computational workflow that combines quantum chemical calculations and machine learning techniques to predict the catalytic performance of a wide range of catalysts in the nitrogen reduction reaction (NRR). The analysis of the trained models provides insights into the complex structure–activity relationship in experimental catalytic ...

CONTRIBUTIONS TO THE BIOCHEMISTRY OF BROMINE: II. THE BROMINE CONTENT OF HUMAN TISSUES

, 1937
A study of the bromine content in human tissues was made by the method outlined in Part I of this series. In many cases, total halogen determinations were made on the same material.

Steric Coordination Modulated Iodine Chemistry With Four‐Electron Conversion for Zinc‐Iodine Batteries

Advanced Materials, EarlyView.
A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

The contribution of anthropogenic bromine emissions to past stratospheric ozone trends: a modelling study [PDF]

Atmospheric Chemistry and Physics, 2009
Bromine compounds play an important role in the depletion of stratospheric ozone. We have calculated the changes in stratospheric ozone in response to changes in the halogen loading over the past decades, using a two-dimensional (latitude/height) model ...

Interfacial Electronic Restructuring in MAPbBr3/rGO Hybrids Enabling Improved Charge Extraction for Efficient Photodetection

Advanced Materials Interfaces, EarlyView.
MAPbBr3/rGO hybrids exhibit interfacial electronic restructuring that enhances charge extraction in photodetectors. The incorporation of rGO modifies the surface chemical environment, enhances electron‐dominated transport, and suppresses performance degradation, resulting in higher responsivity, detectivity, and photostability than in pristine MAPbBr3 ...
