Some properties on group-graded weakly regular rings(群分次弱正则环的若干性质)

Zhejiang Daxue xuebao. Lixue ban, 2006
首先引入群分次弱正则环的概念，在此基础上证明了 ：(1)设G是群，J是K的分次理想，Jσ=Kσ∩J，则K是群分次弱正则环当且仅当J和K/J是群分次弱正则环.(2)假设K是一个环，n是任一正整数，则K是群分次弱正剐的当且仅当Mn(K）是群分次弱正则的.如果K是群G分次环，则Ke是K的子环，且1∈Ke（其中e是群G的单位元）.得到了群G-分次环K与Ke的一些关系.再者，引进了分次半平坦模的概念，并有如下主要结果：环K是分次弱正则的当且仅当所有右K-模是分次半平坦的.群分次弱正则环推广了群分次正则环，从而得到群分次正则环的相应结果.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells

Advanced Functional Materials, EarlyView.
Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,

Nanoscale Mapping of Plasmonic Charge Transport in Nano‐Resonators Based on Resistive Switching Materials

Advanced Functional Materials, EarlyView.
In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.
