| 1 | Interfacial adsorption-insertion mechanism induced by phase boundary toward better aqueous Zn-ion battery显示文摘Biphasic and multiphasic compounds have been well clarified to achieve extraordinary electrochemical properties as advanced energy storage materials.Yet the role of phase boundaries in improving the performance is remained to be illustrated.Herein,we reported the biphasic vanadate,that is,Na_(1.2)V_(3)O_(8)/K_(2)V_(6)O_(16)·1.5H_(2)O(designated as Na0.5K0.5VO),and detected the novel interfacial adsorption-insertion mechanism induced by phase boundaries.Firstprinciples calculations indicated that large amount of Zn^(2+)and H^(+)ions would be absorbed by the phase boundaries and most of them would insert into the host structure,which not only promote the specific capacity,but also effectively reduce diffusion energy barrier toward faster reaction kinetics.Driven by this advanced interfacial adsorption-insertion mechanism,the aqueous Zn/Na_(0.5)K_(0.5)VO is able to perform excellent rate capability as well as long-term cycling performance.A stable capacity of 267 mA h g^(-1)after 800 cycles at 5 A g^(-1)can be achieved.The discovery of this mechanism is beneficial to understand the performance enhancement mechanism of biphasic and multiphasic compounds as well as pave pathway for the strategic design of highperformance energy storage materials. | Lutong Shan Yiren Wang Shuquan Liang Boya Tang Yongqiang Yang Ziqing Wang Bingan Lu Jiang Zhou | 2021 | InfoMat2021，3，9： | 8 |

| 3 | CO_(2)fractional laser-assisted transdermal delivery of silk nanofiber carriers in a rabbit ear hypertrophic scar model显示文摘Background:Hypertrophic scars are skin fibrotic diseases,characterized by fibroblast hyperprolif-eration and excessive accumulation of extracellular matrix.However,topical drug application for hypertrophic scars are unsatisfactory.The purpose of this study was to explore the permeability of silk nanofiber hydrogels(SNFs)loaded with rhodamine 6G(R6G)and rhodamine 110(R110)mediated by CO_(2)fractional laser irradiation into hypertrophic scar tissues.Methods:In this work,R6G and R110 were chosen as hydrophilic and hydrophobic model molecules.They were loaded inside SNFs.In vivo rabbit ear hypertrophic scars were treated with CO_(2)fractional laser irradiation and then R6G/R110-laden SNFs were applied to the scars to evaluate their synergetic effect on drug penetration efficiency.Their permeability was quantified by fluorescence intensity and measured by confocal laser scanning microscopy on days 1,3,5 and 7.More specifically,the thermal coagulation zone(CZ)and its surrounding area(peri-CZ)caused by the thermal coagulation of the laser were discussed separately.Results:Our data indicated that the SNFs promoted the penetration of R6G but not that of R110 in the peri-CZ on day 1 when combined with laser irradiation.Interestingly,both R6G and R110 were abundant in the CZ and remained stable on days 1,3 and 5.Moreover,rapid re-epithelialization hindered the long-term permeability of both drugs.Conclusion:Combining CO_(2)fractional laser irradiation with SNF drug delivery could improve the efficiency of hydrophilic drug delivery within 24 h before total re-epithelialization. | Yan Yang Lutong Liu Xiaojin Wu Xue Wang Qiang Lu Zhen Zhang | 2022 | Burns & Trauma2022，10，1： | 0 |
| 4 | Synthesis of(HfZrTiNbTa)N powders via nitride thermal reduction with soft mechano-chemical assistance显示文摘High-entropy nitride powders are one of prerequisite materials for the preparation of high-performance high-entropy nitride ceramics.In this paper,high-entropy(HfZrTiNbTa)N powders were synthesized via nitride(i.e.,silicon nitride(Si_(3)N_(4)))thermal reduction with soft mechanochemical assistance.The results show that metal oxides like hafnium dioxide(HfO_(2)),zirconium dioxide(ZrO_(2)),titanium dioxide(TiO_(2)),niobium pentoxide(Nb_(2)O_(5)),and tantalum pentoxide(Ta_(2)O_(5))can all be transformed into the corresponding metal nitrides in the presence of Si_(3)N_(4)at 1700℃,and solid solution of the metal nitrides can be formed as the temperature increases to 2100℃.The high-entropy(HfZrTiNbTa)N powders with submicron-sized particles,a narrower size distribution,and a single face-centered cubic(fcc)structure are obtained from raw material mixtures ground for 10 h and subsequently sintered at 1800℃.In addition,the high-entropy bulk nitride ceramics with relative density(Rw)of 94.31%±0.76%,Vickers hardness of 21.00±0.94 GPa,and fracture toughness(KIC)of 3.18±0.16 MPa·m1/2 are obtained with submicron-sized powders,which are superior to those obtained with micron-sized powders. | Xiang Liu Youjun Lu Qian Xu Lutong Yang Hongfang Shen Wenzhou Sun Xiao Zhang Yanmin Wang | 2023 | Journal of Advanced Ceramics2023，12，3： | 0 |
