| 1 | Mechanism underlying the protective effect of Kaixin Jieyu Fang on vascular depression following cerebral white matter damage显示文摘The Chinese compound Kaixin Jieyu Fang can be used to treat vascular depression;however,the underlying mechanism remains unclear.This study established a rat model of chronic cerebral ischemia-caused white matter damage by ligation of the bilateral common carotid arteries.Rats received daily intragastric administration of a suspension of Kaixin Jieyu Fang powder.After 3,7and 21 days of treatment,the degree of white matter damage in the cerebral ischemia rat model was alleviated,Bcl-2 protein and mRNA expression in brain tissue increased,and Bax protein and mRNA expression decreased.These results indicate that Kaixin Jieyu Fang can alleviate cerebral white matter damage,and the underlying mechanism is associated with regulation of Bcl-2/Bax protein and mRNA expression,which is one of possible mechanism behind the protective effect of Kaixin Jieyu Fang against vascular depression. | Ying Zhang Shijing Huang Yanyun Wang Junhua Pan Jun Zheng Xianhui Zhang Yuxia Chen Duojiao Li | 2014 | Neural Regeneration Research2014,9,1: | 4 |

| 3 | UV light-induced oxygen doping in graphitic carbon nitride with suppressed deep trapping for enhancement in CO_(2) photoreduction activity显示文摘While photoreduction of CO_(2) to CH 4 is an effective means of producing value-added fuels,common pho-tocatalysts have poor activity and low selectivity in photocatalytic CO_(2)-reduction processes.Even though creating defects is an effective photocatalyst fabrication route to improve photocatalytic activity,there are some challenges with the facile photocatalyst synthesis method.In this work,an O element is in-troduced into a graphitic carbon nitride(CN)skeleton through a precursory ultraviolet light irradiation pretreatment to increase the visible light absorption and enhance the carrier density of this modified non-metal CN photocatalyst;the charge transfer dynamics thereof are also studied through electrochem-ical tests,photoluminescence spectroscopy,and nanosecond transient absorption.We verify that the op-timized sample exhibits lower charge recombination and a suppressed 84 ns electron-trapping lifetime,compared to the 103 ns electron-trapping lifetime of the CN counterpart,and thereby contributes to ro-bust detrapping and a fast transfer of active electrons.Through density functional theory calculations,we find that the improved light absorption and increased electron density are ascribed to O-element doping,which enhances the CO_(2) adsorption energy and improves the CO_(2)-to-CH 4 photoreduction activity;it be-comes 17 times higher than that of the bare CN,and the selectivity is 3.8 times higher than that of CN.Moreover,the optimized sample demonstrates excellent cyclic stability in a 24-hour cycle test. | Xiaolong Zhao Xiaoping Yi Wending Pan Yifei Wang Shijing Luo Yingguang Zhang Ruijie Xie Dennis Y.C.Leung | 2023 | Journal of Materials Science & Technology2023,,2: | 1 |
| 4 | Solid-state Al-air battery with an ethanol gel electrolyte显示文摘Hydrogel electrolyte is especially suitable for solid-state Al-air batteries targeted for various portable applications, which may, however, lead to continuous Al corrosion during battery standby. To tackle this issue, an ethanol gel electrolyte is developed for Al-air battery for the first time in this work, by using KOH as solute and polyethylene oxide as gelling agent. The ethanol gel is found to effectively inhibit Al corrosion compared with the water gel counterpart, leading to stable Al storage. When assembled into an Al-air battery, the ethanol gel electrolyte achieves a much improved discharge lifetime and specific capacity, which are 5.3 and 4.1 times of the water gel electrolyte at 0.1 mA cm^(-2), respectively.By studying the gel properties, it is found that a lower ethanol purity can improve the battery power output, but at the price of decreased discharge efficiency. On the contrary, a higher polymer concentration will decrease the power output, but can bring extra benefit to the discharge efficiency. As for the gel thickness, a moderate value of 1 mm is preferred to balance the power output and energy efficiency. Finally, to cater the increasing market of flexible electronics, a flexible Al-air battery is developed by impregnating the ethanol gel into a paper substrate, which can function normally even under serious deformation or damage. | Yifei Wang Wending Pan Kee Wah Leong Shijing Luo Xiaolong Zhao Dennis Y.C.Leung | 2023 | Green Energy & Environment2023,8,4: | 0 |
| 5 | Recent Progress and Prospects on Dendrite-free Engineerings for Aqueous Zinc Metal Anodes显示文摘Rechargeable zinc-ion batteries with mild aqueous electrolytes are one of the most promising systems for large-scale energy storage as a result of their inherent safety,low cost,environmental-friendliness,and acceptable energy density.However,zinc metal anodes always suffer from unwanted dendrite growth,leading to low Coulombic efficiency and poor cycle stability and during the repeated plating/stripping processes,which substantially restrict their further development and application.To solve these critical issues,a lot of research works have been dedicated to overcoming the drawbacks associated with zinc metal anodes.In this overview,the working mechanisms and existing issues of the zinc metal anodes are first briefly outlined.Moreover,we look into the ongoing processes of the different strategies for achieving highly stable and dendrite-free zinc metal anodes,including crystal engineering,structural engineering,coating engineering,electrolyte engineering,and separator engineering.Finally,some challenges being faced and prospects in this field are provided,together with guiding significant research directions in the future. | Jiangmin Jiang Zhiwei Li Zhenghui Pan Shijing Wang Yaxin Chen Quanchao Zhuang Zhicheng Ju Xiaogang Zhang | 2023 | Energy & Environmental Materials2023,6,3: | 0 |
| 6 | Paper-based aqueous Al ion battery with water-in-salt electrolyte显示文摘Low-cost,flexible and safe battery technology is the key to the widespread usage of wearable electronics,among which the aqueous Al ion battery with water-in-salt electrolyte is a promising candidate.In this work,a flexible aqueous Al ion battery is developed using cellulose paper as substrate.The water-in-salt electrolyte is stored inside the paper,while the electrodes are either printed or attached on the paper surface,leading to a lightweight and thin-film battery prototype.Currently,this battery can tolerate a charge and discharge rate as high as 4 A g^(-1) without losing its storage capacity.The charge voltage is around 2.2 V,while the discharge plateau of 1.6–1.8 V is among the highest in reported aqueous Al ion batteries,together with a high discharge specific capacity of~140 mAh g^(-1).However,due to the water electrolysis side reaction,the faradaic efficiency can only reach 85%with a cycle life of 250 due to the dry out of electrolyte.Benefited from using flexible materials and aqueous electrolyte,this paper-based Al ion battery can tolerate various deformations such as bending,rolling and even puncturing without losing its performance.When two single cells are connected in series,the battery pack can provide a charge voltage of 4.3 V and a discharge plateau as high as 3–3.6 V,which are very close to commercial Li ion batteries.Such a cheap,flexible and safe battery technology may be widely applied in low-cost and large-quantity applications,such as RFID tags,smart packages and wearable biosensors in the future. | Yifei Wang Wending Pan Kee Wah Leong Yingguang Zhang Xiaolong Zhao Shijing Luo Dennis Y.C.Leung | 2023 | Green Energy & Environment2023,8,5: | 0 |
