Lone‐Pair‐Induced Lattice Distortion in Lead‐Free Hybrid Perovskites for High‐Performance Nanogenerators

Advanced Functional Materials, EarlyView.
A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Thickness‐Programmable Opto‐Memristive Dynamics in 6‐In Wafer‐Scale Atomic‐Layer‐Controlled WS2 for Reservoir Computing

Advanced Functional Materials, EarlyView.
A 6‐in wafer‐scale atomic‐layer‐controlled tungsten disulfide (WS2) is achieved by combining plasma‐assisted synthesis with three‐gas reactive ion etching. Precise layer control enables tunable band‐gap evolution and pulse‐history‐dependent opto‐memristive dynamics.

Dynamic Multi-Symbol Flipping Decoding of Non-Binary LDPC Codes

IEEE Open Journal of the Communications Society, 2022
A dynamic multi-symbol (DM) flipping scheme is proposed for various symbol flipping decodings of non-binary low-density parity-check (NB-LDPC) codes. This new approach divides the whole decoding process into multiple stages according to the number of ...

MOBILE COMMUNICATIONS, MOBILE LANGUAGE

Information and Telecommunication Sciences, 2013
The present paper addresses essential discourse elements of the English language of science in light of the so-called Anglo-American intellectual style. Emphasised here are: various linguistic devices of compression (writing succinctly, avoidingverbosity and negation etc.), keeping subject and verb close together, and common revision patterns.
