Sodium-ion batteries (SIBs) are leading candidates to address the energy crisis and lithium depletion. Layered transition metal (TM) oxides regarded as some of most promising cathode materials for SIBs due their high capacities, rate capability, low cost. However, practical application layered TM oxide cathodes is significantly challenged by limitations in both density cycle life, specifically at extreme temperatures. Herein, we summarize fundamental issues newly proposed strategies on...
Abstract Li‐rich layered oxides (LRLO) exhibit significant potential for use in all‐solid‐state lithium batteries (ASSLBs) owing to their high capacities and wide range of operating voltages. However, the practical application LRLO ASSLBs is hindered by severe failure carrier transport at solid–solid interface, which subsequently limits electrochemical activity these batteries. Here, spatially asynchronous activation mechanism presented. A spectroscopic study extending from surface into bulk...
Colloidal semiconductor II-VI metal chalcogenide (ME) magic-size clusters (MSCs) exhibit either an optical absorption singlet or doublet. In the latter case, a sharp photoluminescence (PL) signal is observed. Whether PL-inactive MSCs transform to PL-active ones unknown. We show that CdS MSC-322 transforms MSC-328 and MSC-373 in presence of acetic acid (HOAc). displays at ≈322 nm, whereas both have broad absorptions respectively around 328 373 nm. reaction cadmium myristate S powder...
Abstract The high energy density, low cost, and toxicity of LiNi 0.8 Co 0.1 Mn O 2 (NCM811) cathodes has led to their large‐scale mass production. However, the poor interfacial stability between NCM811 organic electrolytes impairs long‐cycle performance lithium ions batteries. In this study, carbonized polymer dots (CPDs) are successfully introduced onto surface (NCM811@CPDs) via a simple physical mixing process. CPDs with rich oxygen functional groups form strong covalent bonds transition...
We report the spectroscopic properties and thermal stability of Tm3+-doped Ga2O3–GeO2–Bi2O3–PbO(PbF2) glasses for 1.47-μm optical amplifications. Effects PbF2 doping on gallate–germanium–bismuth–lead glass are investigated. The measured peak wavelength full width at half-maximum fluorescence 1465 nm ~120 nm, respectively. Significant enhancement emission lifetime a 3H4 level with increasing have been observed. presence GeO2 provides two potentials shortening ultraviolet cutoff band host glasses.
We investigate the spectroscopic properties of 1.53-μm emission from 4I13/2→4I15/2 transition Er3+ ions in Al(PO3)3-based fluorophosphate glass for applications broadband fibre amplifiers. The peak locates at ~1530 nm with a full width half-maximum ~65 nm. measured lifetime and calculated cross-section this are ~8.1 ms ~7.6×10−21 cm2, respectively. Frequency upconversion to 4F7/2 state occurs simultaneously upon excitation 977-nm laser diode. Three infrared-to-visible emissions centred...

Abstract The development of deep learning provides a new way for solving the colorization problem on grayscale image. Excellent coding‐based methods appear in automatic image task, avoiding unsaturated colour effect previous based L2 loss function. Traditional neural networks come with high computational costs and large number parameters. Considering limitation memory computing resources aiming at lightweight, novel grey network is proposed. basic idea used, regarding task as pixel‐level...

Abstract That magic‐size clusters (MSCs) have their counterpart precursor compounds (PCs) has not been generally accepted by expertise circles. Here, experimental evidence to support this new concept is presented. With aqueous‐phase CdSe MSCs as a model system, it shown that when the are dispersed in water containing certain amount of L‐cysteine (Cys), disappear slowly. Upon addition CdCl 2 , recover. It proposed after dispersing, transform quasi‐isomeric, non‐absorbing PCs upon Cys...
