Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Controllable Preparation and Microwave Absorption Properties of BaTiO3 Nanoparticles Based on Solvothermal Method [PDF]

, 2017
钛酸钡BaTiO3是一种很有发展前景的吸波材料，然而其高频波段吸波效率较低，阻碍了它在电磁波吸收领域的广泛应用。本文首先采用溶剂热法，以低成本的四氯化钛（TiCl4）和八水合氢氧化钡（Ba(OH)2•8H2O）作为原料，可控制备出一系列形貌不同的BaTiO3纳米颗粒，再将制备的BaTiO3纳米颗粒与介电常数较大的氧化石墨烯（GO）进行复合，经氩气保护煅烧得到钛酸钡/还原氧化石墨烯（BaTiO3/RGO）纳米复合物。并系统研究了实验参数对BaTiO3 ...

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

Advanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

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 ...
