Sodium-ion batteries offer an attractive option for potential low cost and large scale energy storage due to the earth abundance of sodium. Red phosphorus is considered as a high capacity anode sodium-ion with theoretical 2596 mAh/g. However, similar silicon in lithium-ion batteries, several limitations, such volume expansion upon sodiation/desodiation electronic conductance, have severely limited performance red anodes. In order address above challenges, we developed method deposit nanodots...
Two-dimensional (2D) semiconducting monolayer transition metal dichalcogenides (TMDCs) have stimulated lots of interest because they are direct bandgap materials that reasonably good mobility values. However, contact between most metals and TMDCs like 2H phase WSe2 highly resistive, thus degrading the performance field effect transistors (FETs) fabricated with as active channel materials. Recently, a engineering concept 2D MoS2 was developed, improved device performance. Here, we applied...
Monolayer WSe2 is a two-dimensional (2D) semiconductor with direct band gap, and it has been recently explored as promising material for electronics optoelectronics. Low field-effect mobility the main constraint preventing from becoming one of competing channel materials transistors (FETs). Recent results have demonstrated that chemical treatments can modify electrical properties transition metal dichalcogenides (TMDCs), including MoS2 WSe2. Here, we report controlled heating in air...
Lithium-ion batteries have been regarded as one of the most promising energy storage devices, and development low-cost with high density is highly desired so that cost per watt-hour ($/Wh) can be minimized. In this work, we report using ball-milled silicon (Si) starting material subsequent carbon coating to produce hierarchical carbon-coated (HCC) Si. The obtained particles prepared from different Si sources all show excellent cycling performance over 1000 mAh/g after cycles. Interestingly,...
Sodium-ion batteries offer an attractive option for grid-level energy storage due to the high natural abundance of sodium and low material cost compounds. Phosphorus (P) is a promising anode sodium-ion batteries, with theoretical capacity 2596 mAh/g. The red phosphorus (RP) form has worse electronic conductivity lower initial Coulombic efficiency than black (BP), but limited production have slowed development BP anodes. To address these challenges, we developed simple scalable method...
Nonvolatile, flexible artificial synapses that can be used for brain-inspired computing are highly desirable emerging applications such as human–machine interfaces, soft robotics, medical implants, and biological studies. Printed devices based on organic materials very promising these due to their sensitivity ion injection, intrinsic printability, biocompatibility, great potential flexible/stretchable electronics. Herein, we report the experimental realization of a nonvolatile synapse using...
Leisure activities are major components of modifiable and healthy lifestyles proposed to help prevent the development dementia. This study aimed assess effects different types leisure activities, including cognitive, physical, social on incidence all-cause dementia (ACD), Alzheimer disease (AD), vascular (VD).We performed a systematic review meta-analysis Cochrane, PubMed, Embase, Web Science databases identify longitudinal studies that examined associations between Relative risks (RRs) 95%...
Abstract In this work, we study the lithiation behaviours of both porous silicon (Si) nanoparticles and Si nanowires by in situ ex transmission electron microscopy (TEM) compare them with solid nanowires. The TEM observation reveals that critical fracture diameter particles reaches up to 1.52 μm, which is much larger than previously reported 150 nm for crystalline 870 amorphous nanoparticles. After full lithiation, transform Li 15 4 phase while x phase, due effect domain size on stability as...
Black phosphorus (BP) has been recently rediscovered as an elemental two-dimensional (2D) material that shows promising results for next generation electronics and optoelectronics because of its intrinsically superior carrier mobility small direct band gap. In various 2D field-effect transistors (FETs), the choice metal contacts is vital to device performance, it a major challenge reach ultralow contact resistances highly scaled FETs. Here, we experimentally show effect work function tunable...
Horizontal ecological compensation represents a significant institutional innovation aimed at advancing civilization and serves as key functional strategy within China’s current management framework.

Attention deficit hyperactivity disorder (ADHD) and tic (TD) are two common neurodevelopmental disorders that frequently occur in childhood, these often coexist. Cluster analysis provides a novel perspective on the heterogeneity of commonly observed clinical disorders. We recruited patients with comorbid ADHD TD from Beijing Children's Hospital between May 2022 August 2023, collecting data their symptoms functional impairments. The number clusters was determined using elbow method, K-means...
Abstract Atomic layer deposition (ALD) has been used to modify the surface of high‐voltage cathode LiNi 0.5 Mn 1.5 O 4 by coating ultrathin Al 2 3 layers on electrodes. The can suppress undesirable reactions during cycling while retaining electron and ion conductivity electrode. ‐coated showed remarkable improvement over bare . After 200 cycles, 91 % capacity retention whereas only maintain 75 under same testing conditions. In addition, retained 63 its 900 cycles. At an elevated temperature...
