A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

Advanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.

Multicyclic D‐Stereospecific Hydrolase Dimer With High Sustained Activity

Angewandte Chemie, EarlyView.
Protein macrocyclization was applied to a thermally unstable D‐stereospecific hydrolase using in situ cyclization of proteins (INCYPRO). This site‐specific cross‐linking approach enhanced the resistance of the enzyme to heat and cosolvents.

Impact of Discharging Methods on Electrode Integrity in Recycling of Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Electrical and electrochemical discharge methods for end‐of‐life lithium‐ion batteries are compared. Electrochemical discharge better preserves the composition and layered structure of Ni‐rich cathode materials while minimizing residual lithium compounds.

Synthesis of Conjugated Linear and Cyclic Polyynes by Selective Alkyne Metathesis

Angewandte Chemie, EarlyView.
The formation of polyynes with an odd number of conjugated triple bonds is challenging, particularly for complex architectures since most established methods rely on irreversible C–C bond‐forming reactions. To address this, we have developed the synthesis of triynes via alkyne metathesis.

Light Stability of Laser‐Assisted Glass Encapsulated Perovskite Solar Cells under Different Atmospheres

Advanced Energy Materials, EarlyView.
This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Steering the Shape‐shifting of Bullvalene‐PdII Complexes Through Steric and Geometric Strain

Angewandte Chemie, EarlyView.
This study explores the use of bis‐pyridyl substituted bullvalenes as dynamic shape‐shifting ligands within cis‐capped PdII complexes. The ring position of the pyridyl nitrogen is critical, leading to a range of Pd2L2 metallacycles and simple PdL complexes, each with distinctive bullvalene isomer preferences (represented in the figure by A‐D isomer ...

Automatic Determination of Quasicrystalline Patterns from Microscopy Images

Advanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

Chaotic Crystallography: How the physics of information reveals structural order in materials

, 2014
We review recent progress in applying information- and computation-theoretic measures to describe material structure that transcends previous methods based on exact geometric symmetries.

opXRD: Open Experimental Powder X‐Ray Diffraction Database

Advanced Intelligent Discovery, EarlyView.
We introduce the Open Experimental Powder X‐ray Diffraction Database, the largest openly accessible collection of experimental powder diffractograms, comprising over 92,000 patterns collected across diverse material classes and experimental setups. Our ongoing effort aims to guide machine learning research toward fully automated analysis of pXRD data ...

Residue‐Specific Signatures of Structural Water Identified by Dissolution Dynamic Nuclear Polarization with UV‐Generated Radicals

Angewandte Chemie, EarlyView.
Structural water molecules in proteins are notoriously hard to detect in solution. Hyperpolarized water with UV radicals as polarizing agents provides the sensitivity and resolution to detect residue‐specific signatures of structural water with NMR spectroscopy.
