Lattice Coherency‐Driven (111)‐Oriented Wide Bandgap Perovskite Films

Advanced Energy Materials, EarlyView.
Methylammonium lead chloride (MAPbCl3)‐derived seed templates regulate wide‐bandgap perovskite crystallization through coupled thermodynamic and kinetic effects. Lattice‐coherent templating lowers the energy cost for (111) epilayer growth, while growth retardation controls crystallization kinetics, ultimately producing highly crystalline face‐up (111 ...

Pricing Dynamics in the US Hemp Market: A Vertical Price Transmission Analysis of the Hemp Value Chain

Agribusiness, EarlyView.
ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...

CALIBRATION OF THE JOHNSON-COOK EQUATION FOR THE COMPONENTS OF THERMOBIMETAL BRASS/INVAR

IZVESTIA VOLGOGRAD STATE TECHNICAL UNIVERSITY
This study investigates the mechanical properties of the components of a brass/Invar thermobimetal produced by explosive welding. Based on the results of tensile tests at room temperature and a comprehensive analysis of literature data on material behavior under high strain rates and elevated temperatures, complete parameter sets for the Johnson-Cook ...

Deep Learning–Based Extraction of Promising Material Groups and Common Features from High‐Dimensional Data: A Case of Optical Spectra of Inorganic Crystals

Advanced Intelligent Discovery, EarlyView.
We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...
