The C─S/C═S Bonds Synergistically Modify Porous Hollow‐Carbon‐Nanocages Anode for Durable and Fast Sodium‐Ion Storage

Huiyan Feng, Zhendong Liu, Fei Wang, Lingxiao Xue, more

Advanced Functional Materials > 34 > 33 > n/a - n/a

Sulfur doping in carbonaceous anode is a popular method to improve the sodium storing performance. Regulating the C/S bond effect of carbon atom with doped sulfur atom could understand and develop superior carbonaceous anode for sodium‐ion batteries. Therefore, this study designed porous hollow carbon nanocages with synergistically‐doped C/S bonds (C‐S/C = S) by secondary‐sulfidation. The secondary‐sulfidation...

Small > 20 > 4 > n/a - n/a

Microsized‐Carbon Anodes In article number 2305841, Chengzhi Zhang, Jun Tan, Jinshui Liu, and co‐workers propose heterogeneous carbon‐carbon composite design with robust structure. The confinement effect originating from expanded‐graphite skeletons suppressed the crystallization degree of pitch‐derived carbon and contributed rich edge‐defect sites in composites, providing high capacity and stability...

Robust Micro‐Sized and Defect‐Rich Carbon–Carbon Composites as Advanced Anodes for Potassium‐Ion Batteries

Zhuohua Quan, Fei Wang, Yuchen Wang, Zhendong Liu, more

Small > 20 > 4 > n/a - n/a

Pitch‐derived carbon (PC) anode features the merits of low‐cost, rich edge‐defect sites, and tunable crystallization degree for potassium ion batteries (PIBs). However, gaining the PC anode with both rich edge‐defect sites and robust structure remains challenging. Herein, micro‐sized and robust PC/expanded‐graphite (EG) composites (EGC) with rich edge‐defect sites are massively synthesized via melting...

Engineering CSFe Bond Confinement Effect to Stabilize Metallic‐Phase Sulfide for High Power Density Sodium‐Ion Batteries

Fei Wang, Zhendong Liu, Huiyan Feng, Yuchen Wang, more

Small > 19 > 37 > n/a - n/a

Metallic‐phase iron sulfide (e.g., Fe₇S₈) is a promising candidate for high power density sodium storage anode due to the inherent metal electronic conductivity and unhindered sodium‐ion diffusion kinetics. Nevertheless, long‐cycle stability can not be achieved simultaneously while designing a fast‐charging Fe₇S₈‐based anode. Herein, Fe₇S₈ encapsulated in carbon‐sulfur bonds doped hollow carbon fibers...

Small > 19 > 37 > n/a - n/a

Sodium Anode Materials In article number 2302200, Chengzhi Zhang, Jun Tan, Jinshui Liu, and co‐workers present a high‐power density sodium‐ion batteries (SIBs) anode that Fe₇S₈ encapsulated in carbon‐sulfur bonds doped carbonaceous fibers (NHCFs‐S‐Fe₇S₈). The multinomial optimized NHCFs‐S‐Fe₇S₈ integrates a suitable structure for high power density and longer cycle life SIBs.

Coating dense silicon carbide layer on artificial graphites to achieve synergistically enhanced thermal conductivity and electronic insulation of polymer composites

Min Huang, Yexin Tian, Nizao Kong, Gen Liao, more

Journal of Applied Polymer Science > 140 > 25 > n/a - n/a

As a potential thermal conductive filler, spherical graphite (SG) has high thermal conductivity, low density, and a good spherical shape structure. However, the poor electrical insulation of SG will seriously limit its application in highly integrated electronic device packaging. Herein, through a simple liquid–solid chemical reaction, the surface of the SG particle is firmly covered by a uniform...

The microstructures and mechanical properties of ultra-high-strength PAN-based carbon fibers during graphitization under a constant stretching

Chong Ye, Huang Wu, Dong Huang, Baoliu Li, more

Carbon Letters > 2019 > 29 > 5 > 497-504

Commercial ultra-high-strength PAN-based carbon fibers (T1000G) were heat-treated at the temperature range of 2300–2600 °C under a constant stretching of 600 cN. After continuous high-temperature graphitization treatment, microstructures, mechanical properties and thermal stability of the carbon fibers were investigated. The results show that the T1000G carbon fibers present the similar round shape...

A comprehensive study on the oxidative stabilization of mesophase pitch-based tape-shaped thick fibers with oxygen

Guanming Yuan, Xuanke Li, Xiaoqing Xiong, Zhijun Dong, more

Carbon > 2017 > 115 > C > 59-76

Tape-shaped pitch fibers with a transverse cross-sectional size of 400 μm width and ∼30 μm thickness, melt-spun from mesophase pitch, were adopted as a model for treatment in oxygen using various temperatures and durations to investigate their stabilization behavior. Several characterization techniques were used to systematically analyze the functional group species, oxygen content and distribution,...

Caffeine is responsible for the bloodglucose-lowering effects of green tea and Puer tea extractsin BALB/c mice

Chong-Ye FANG, Xuan-Jun WANG, Ye-Wei HUANG, Shu-Mei HAO, more

Chinese Journal of Natural Medicines > 2015 > 13 > 8 > 595-601

The present study was designed to determine the effects of Puer tea and green tea on blood glucose level. Male BALB/c mice were administered green tea extract (GTE) or Puer tea extract (PTE), either intragastrically or in their drinking water. The major components of these teas are epigallocatechin gallate (EGCG) and caffeine, respectively. Blood glucose measurement results showed that mice fed intragastrically...

Managing emergency department overcrowding via ambulance diversion: A discrete event simulation model

Chih-Hao Lin, Chung-Yao Kao, Chong-Ye Huang

Journal of the Formosan Medical Association > 2015 > 114 > 1 > 64-71

Ambulance diversion (AD) is considered one of the possible solutions to relieve emergency department (ED) overcrowding. Study of the effectiveness of various AD strategies is prerequisite for policy-making. Our aim is to develop a tool that quantitatively evaluates the effectiveness of various AD strategies.A simulation model and a computer simulation program were developed. Three sets of simulations...

The generalized Hirota equation is solved analytically through Daubox transformation method. The properties of solitons are investigated analytically based on related expressions. We present the precise balance condition between dispersion, nonlinear parameters, third-order dispersion and time-delay effects, to get stable propagating soliton. We find a condition under which effects of the third-order...
