| 1 | Solid lipid dispersion of calcitriol with enhanced dissolution and stability显示文摘Solid dispersion of calcitriol with lipophilic surfactants and triglycerides was developed by melt-mixing method to modify the release and enhance stability of the drug.The solid dispersions were characterized by differential scanning calorimetry(DSC),hot stage polarized optical microscopy(HSPM),infrared spectroscopy(FTIR)and stability studies.The solid dispersion significantly enhanced the stability of calcitriol,which could be attributed to the high antioxidant activity of the solid lipid dispersion.The rapid dissolution rate from the solid dispersion was attributed to the amorphous or solid solution state of drug with improved specific surface area and wettability than the drug crystals.Therefore,solid dispersion of calcitriol with D-a-tocopheryl polyethylene glycol 1000 succinate(TPGS)offers a good approach to modify the release and enhance stability of calcitriol.The influence of lipophilic solid dispersion on drug bioavailability needs further investigation. | Ting Yuan Lingzhen Qin Zhouhua Wang Jinyuan Nie Zhefei Guo Ge Li Chuanbin Wu | 2013 | Asian Journal of Pharmaceutical Sciences2013，8，1： | 2 |
| 2 | Fabricated temperature sensitive photocatalyst of PNIPAM@ZnO/C for controllable photocatalytic activity显示文摘PNIPAM@ZnO/C composite photocatalyst was prepared by cross-linking polymerization technology with N-isopropylacrylamide used as functional monomer, N,N'-methylenebis(acrylamide) used as crosslinking agent, ammonium persulfate used as initiator, and 3-(trimethoxysilyl) propyl methacrylate used as surface modification reagent. The morphology, structure, electrochemical and photocatalytic properties of as-prepared samples were characterized via the serial tests. The temperature-response performances of PNIPAM@ZnO/C were evaluated by the photocatalytic degradation of tetracycline(TC)under different temperatures. The results show that the synthesized composite photocatalysts possess the excellent and switchable photocatalytic activity. The photocatalytic degradation activity of PNIPAM@ZnO/C is suppressed above the lower critical solution temperature(LCST), and it is enhanced below the LCST. | Pengwei Huo Jinze Li Zhefei Ye Huiqin Wang Xinlin Liu Xiuying Li Yongsheng Yan | 2017 | Chinese Chemical Letters2017，28，12： | 2 |
| 3 | Achieving high-capacity and long-life K^(+)storage enabled by constructing yolk-shell Sb_(2)S_(3)@N,S-doped carbon nanorod anodes显示文摘As promising anode candidates for potassium-ion batteries(PIBs),antimony sulfide(Sb_(2)S_(3))possesses high specific capacity but suffers from massive volume expansion and sluggish kinetics due to the large K^(+)insertion,resulting in inferior cycling and rate performance.To address these challenges,a yolk-shell structured Sb_(2)S_(3)confined in N,S co-doped hollow carbon nanorod(YS-Sb_(2)S_(3)@NSC)working as a viable anode for PIBs is proposed.As directly verified by in situ transmission electron microscopy(TEM),the buffer space between the Sb_(2)S_(3)core and thin carbon shell can effectively accommodate the large expansion stress of Sb_(2)S_(3)without cracking the shell and the carbon shell can accelerate electron transport and K^(+)diffusion,which plays a significant role in reinforcing the structural stability and facilitating charge transfer.As a result,the YS-Sb_(2)S_(3)@NSC electrode delivers a high reversible K^(+)storage capacity of 594.58 m A h g^(-1)at 0.1 A g^(-1)and a long cycle life with a slight capacity degradation(0.01%per cycle)for 2000 cycles at 1 A g^(-1)while maintaining outstanding rate capability.Importantly,utilizing in in situ/ex situ microscopic and spectroscopic characterizations,the origins of performance enhancement and K^(+)storage mechanism of Sb_(2)S_(3)were clearly elucidated.This work provides valuable insights into the rational design of high-performance and durable transition metal sulfides-based anodes for PIBs. | Bensheng Xiao Hehe Zhang Zhefei Sun Miao Li Yingzhu Fan Haichen Lin Haodong Liu Bing Jiang Yanbin Shen Ming-Sheng Wang Meicheng Li Qiaobao Zhang | 2023 | Journal of Energy Chemistry2023，，1： | 1 |

| 7 | Ultra-thick,dense dual-encapsulated Sb anode architecture with conductively elastic networks promises potassium-ion batteries with high areal and volumetric capacities显示文摘Ultra-thick,dense alloy-type anodes are promising for achieving large areal and volumetric performance in potassium-ion batteries(PIBs),but severe volume expansion as well as sluggish ion and electron diffusion kinetics heavily impede their widespread application.Herein,we design highly dense(3.1 g cm^(-3))Ti_(3)C_(2)T_(x) MXene and graphene dual-encapsulated nano-Sb monolith architectures(HD-Sb@Ti_(3)C_(2)T_(x)-G)with high-conductivity elastic networks(1560 S m^(-1))and compact dually encapsulated structures,which exhibit a large volumetric capacity of 1780.2 mAh cm^(-3)(gravimetric capacity:565.0 mAh g^(-1)),a long-term stable lifespan of 500 cycles with 82%retention,and a large areal capacity of 8.6 mAh cm^(-2)(loading:31 mg cm^(-2))in PIBs.Using ex-situ SEM,in-situ TEM,kinetic investigations,and theoretical calculations,we reveal that the excellent areal and volumetric performance mechanism stems from the three dimensional(3D)high-conductivity elastic networks and the dualencapsulated Sb architecture of Ti_(3)C_(2)T_(x) and graphene;these effectively mitigate against volume expansion and the pulverization of Sb,offering good electrolyte penetration and rapid ionic/electronic transmission.Ti_(3)C_(2)T_(x) also decreases the Kþdiffusion energy barrier,and the ultra-thick compact electrode ensures volumetric and areal performance.These findings provide a feasible strategy for fabricating ultra-thick,dense alloy-type electrodes to achieve high areal and volumetric capacity energy storage via highly-dense,dual-encapsulated architectures with conductive elastic networks. | Zhonggang Liu Xi Liu Bingchun Wang Xinying Wang Dongzhen Lu Dijun Shen Zhefei Sun Yongchang Liu Wenli Zhang Qiaobao Zhang Yunyong Li | 2023 | eScience2023，3，6： | 0 |
| 8 | Synergistic coupling of amorphous carbon and graphitic domains toward high-rate and long-life K^(+) storage显示文摘Amorphous carbon materials hold great potential for practical use in potassium-ion batteries(PIBs)due to their abundant resources,low cost and high structural stability.However,given the challenge of sluggish potassiation kinetics,the rate performance of amorphous carbon is severely hindered.Herein,amorphous carbon compounded with graphitic domains(HG-CNTs)was proposed as an advanced anode for PIBs.As directly verified by in situ transmission electron microscopy(TEM),the graphitic domains guarantee fast K-ions transport in the carbon composite at a high current density,while the amorphous carbon shells ensure the structural integrity during potassiation,thus boosting its fast and durable K^(+)storage.As a PlB anode,the HG-CNTs electrode exhibits not only a super-stable long-term cyclability(191.6 mAh g^(-1)at 1 A g^(-1)with almost no capacity decay over 3000 cycles),but also an outstanding rate performance(184.5 mAh g^(-1)at 2 A g^(-1)).Ex situ Raman and TEM results further suggest that the highly reversible structure of HG-CNTs is responsible for its superior electrochemical stability.This work provides helpful insights into the development of carbonaceous electrodes with both high rate capability and long cycle life for PIBs. | Hehe Zhang Wangqin Li Jianhai Pan Zhefei Sun Bensheng Xiao Weibin Ye Chengzhi Ke Haowen Gao Yong Cheng Qiaobao Zhang Ming-Sheng Wang | 2022 | Journal of Energy Chemistry2022，31，10： | 0 |
| 9 | Tuning the electron transport behavior at Li/LATP interface for enhanced cyclability of solid-state Li batteries显示文摘An interlayer is usually employed to tackle the interfacial instability issue between solid electrolytes(SEs)and Li metal caused by the side reaction.However,the failure mechanism of the ionic conductor interlayers,especially the influence from electron penetration,remains largely unknown.Herein,using Li1.3Al0.3Ti1.7(PO4)3(LATP)as the model SE and LiF as the interlayer,we use metal semiconductor contact barrier theory to reveal the failure origin of Li/LiF@LATP interface based on the calculation results of density functional theory(DFT),in which electrons can easily tunnel through the LiF grain boundary with F vacancies due to its narrow barrier width against electron injection,followed by the reduction of LATP.Remarkably,an Al-LiF bilayer between Li/LATP is found to dramatically promote the interfacial stability,due to the highly increased barrier width and homogenized electric field at the interface.Consequently,the Li symmetric cells with Al-LiF bilayer can exhibit excellent cyclability of more than 2,000 h superior to that interlayered by LiF monolayer(~860 h).Moreover,the Li/Al-LiF@LATP/LiFePO4 solid-state batteries deliver a capacity retention of 83.2%after 350 cycles at 0.5 C.Our findings emphasize the importance of tuning the electron transport behavior by optimizing the potential barrier for the interface design in high-performance solid-state batteries. | Linshan Luo Feng Zheng Haowen Gao Chaofei Lan Zhefei Sun Wei Huang Xiang Han Ziqi Zhang Pengfei Su Peng Wang Shengshi Guo Guangyang Lin Jianfang Xu Jianyuan Wang Jun Li Cheng Li Qiaobao Zhang Shunqing Wu Ming-Sheng Wang Songyan Chen | 2023 | Nano Research2023，16，1： | 0 |
| 10 | Building better solid-state batteries with silicon-based anodes显示文摘Silicon(Si)-based solid-state batteries(Si-SSBs)are attracting tremendous attention because of their high energy density and unprecedented safety,making them become promising candidates for next-generation energy storage systems.Nevertheless,the commercialization of Si-SSBs is significantly impeded by enormous challenges including large volume variation,severe interfacial problems,elusive fundamental mechanisms,and unsatisfied electrochemical performance.Besides,some unknown electrochemical processes in Si-based anode,solid-state electrolytes(SSEs),and Si-based anode/SSE interfaces are still needed to be explored,while an in-depth understanding of solid–solid interfacial chemistry is insufficient in Si-SSBs.This review aims to summarize the current scientific and technological advances and insights into tackling challenges to promote the deployment of Si-SSBs.First,the differences between various conventional liquid electrolyte-dominated Si-based lithium-ion batteries(LIBs)with Si-SSBs are discussed.Subsequently,the interfacial mechanical contact model,chemical reaction properties,and charge transfer kinetics(mechanical–chemical kinetics)between Si-based anode and three different SSEs(inorganic(oxides)SSEs,organic–inorganic composite SSEs,and inorganic(sulfides)SSEs)are systemically reviewed,respectively.Moreover,the progress for promising inorganic(sulfides)SSE-based Si-SSBs on the aspects of electrode constitution,three-dimensional structured electrodes,and external stack pressure is highlighted,respectively.Finally,future research directions and prospects in the development of Si-SSBs are proposed. | Zhefei Sun Quanzhi Yin Haoyu Chen Miao Li Shenghui Zhou Sifan Wen Jianhai Pan Qizheng Zheng Bing Jiang Haodong Liu Kangwoon Kim Jie Li Xiang Han Yan-Bing He Li Zhang Meicheng Li Qiaobao Zhang | 2023 | Interdisciplinary Materials2023，2，4： | 0 |
