X-ray Crystallography - Presentation

, 2016
The present presentation discusses the principles of X-ray crystallography, focusing on the necessity of crystals for amplifying diffraction signals from molecules and the significance of Bragg's Law in determining structural information. It explains the scattering process, the importance of estimating crystallographic phases, and various methods for ...

Hydrazine‐Mediated Thermally Assisted Photocatalytic Ammonia Decomposition Over Layered Protonated Perovskites

Advanced Science, EarlyView.
Herein, a new catalyst, protonated layered perovskite HPrNb2O7, is presented, which exhibits exceptional photocatalytic activity for solar‐driven ammonia decomposition. Its unique structure facilitates the generation of active sites while extending charge carrier lifetime with input thermal energy. Abstract Photocatalytic ammonia decomposition offers a

Dual‐Ligand Strategy in Rh‐Catalyzed Sequential Hydrofunctionalization of Valylene

Advanced Science, EarlyView.
A remarkable dual‐ligand strategy is employed in Rh‐catalyzed sequential coupling reaction of dinucleophiles and 1,3‐enynes with high regio‐ and chemo‐selectivity. Abstract Controlling regio‐ and chemo‐selectivity in transition‐metal‐catalyzed reactions involving coupling reagents with multiple reactive sites remains a significant challenge.

Configuration and Charge Dynamics of Defect‐Cluster‐Dipoles in CaTiO3 for Enhanced Permittivity

Advanced Electronic Materials, EarlyView.
In La‐doped CaTiO3, the clustering of La ion and Ca vacancies is clearly observed and the configuration of such defect‐cluster is validated. Combining photoelctronic and dielectric spectroscopy enables the dielectric relaxation process with the charge transfer routes.

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

Advanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion
