2Bifunctional core–shell co-catalyst for boosting photocatalytic CO_(2) reduction to CH_(4)显示文摘Solar-light-driven CO_(2) reduction CO to CH_(4) and C2H6 is a complex process involving multiple elementary reactions and energy barriers.Therefore,achieving high CH_(4) activity and selectivity remains a significant challenge.Here,we integrate bifunctional Cu2O and Cu-MOF(MOF=metal-organic framework)core–shell co-catalysts(Cu2O@Cu-MOF)with semiconductor TiO_(2).Experiments and theoretical calculations demonstrate that Cu2O(Cu+facilitates charge separation)and Cu-MOF(Cu2+improves the CO_(2) adsorption and activation)in the core–shell structure have a synergistic effect on photocatalytic CO_(2) reduction,reducing the formation barrier of the key intermediate*COOH and*CHO.The photocatalyst exhibits high CH_(4) yield(366.0μmol·g^(-1)·h^(-1)),efficient electron transfer(3283μmol·g^(-1)·h^(-1))and hydrocarbon selectivity(95.5%),which represents the highest activity of Cu-MOF-based catalysts in photocatalytic CO_(2) reduction reaction.This work provides a strategy for designing efficient photocatalysts from the perspective of precise regulation of components.Fangxu Dai Mingming Zhang Jishu Han Zhenjiang Li Shouhua Feng Jun Xing Lei Wang 2024Nano Research2024,17,3:0
3Digestive tract reconstruction in pancreaticoduodenectomy in University Hospitals of China: a national questionnaire survey显示文摘Background Pancreaticoduodenectomy(PD)has been widely applied in general hospitals in China;however,there is still a lack of unified standards for each surgical technique and procedure.This survey is intended to investigate the current status of digestive tract reconstruction after PD in university hospitals in China.Method A cross-sectional survey was conducted among the members of the Young Elite Pancreatic Surgery Club of China by using the Questionnaire for Digestive Tract Reconstruction after Pancreaticoduodenectomy.The questionnaire was disseminated and collected by point-to-point communication via WeChat public platforms.Results A total of 73 valid questionnaires were returned from 65 university hospitals in 28 provincial divisions of China's Mainland.The respondents who performed PD surgery with an annual volume of over 100 cases accounted for 63%.Generally,laparoscopic PD was performed less often than open PD.Child and Whipple reconstructions accounted for 70%and 26%,respectively.The sequence of pancreatoenteric,biliary-enteric,and gastrointestinal reconstruction accounted for 84%of cases.In pancreatoenteric anastomosis,double-layer anastomosis is the most commonly employed type,accounting for approximately 67%,while single-layer anastomosis accounts for 30%.Of the double-layer anastomoses,duct-to-mucosa/dunking(94%/4%)PJ was performed with duct-mucosa using the Blumgart method(39%)and Cattel-Warren(29%),with continuous/interrupted sutures in the inner layer(69%/31%)and continuous/interrupted sutures in the outer layer(53%/23%).In single-layer anastomosis,continuous/interrupted sutures accounted for 41%/45%.In hepatojejunostomy,single-layer/double-layer suture accounted for 79%/4%,and continuous/interrupted suture accounted for 75%/9%.Forty-six percent of the responding units had not applied double-layer biliary-intestinal anastomosis in the last 3 years,75%of the responding surgeons chose the anastomosis method according to bile duct diameter,with absorbable/non-absorbable suture accounting for 86%/12%.PD/pylorus-preserving PD accounted for 79%/11%of GJ cases,the distance between GJ and HJ<30 cm,30-50 cm and>50 cm were 11%,75%,and 14%,respectively.Antecolic/retrocolic GJ accounted for 71%/23%of cases.Twenty-two percent of GJ cases employed Braun anastomosis,while 55%and 19%of GJ cases used linear cutting staplers/tube-type staplers,respectively;60%/14%were reinforced/not reinforced via manual suturing after stapler anastomosis.Manual anastomosis in GJ surgery employed absorbable/non-absorbable sutures(91%/9%).Significant differences in reconstruction techniques were detected between different volumes of PD procedures(<100/year and>100/year),regions with different economic development levels,and between north and south China.Conclusion Digestive tract reconstruction following PD exists heterogeneity in Chinese university hospitals.Corresponding prospective clinical studies are needed to determine the consensus on pancreatic surgery that meets the clinical reality in China.Jishu Wei Qiang Xu Yuhua Zhang Jiabin Jin Xiaodong Tian Qiaofei Liu Zipeng Lu Zheng Wang Shanmiao Gou Song Gao Xianlin Han Yefei Rong Niandong Ji Ye Lin Guolin Li Shi Chen Feng Cao Hua Chen Wenming Wu Yupei Zhao the Young Elite Pancreatic Surgery Club of China 2022Journal of Pancreatology2022,5,3:0
4Small Things Make a Big Difference: the Small-molecule Cross-linker of Robust Water-soluble Network Binders for Stable Si Anodes显示文摘Silicon(Si)with high theoretical capacity has attracted tremendous attention as the next-generation anode material for Li-ion batteries,but the huge expansion during cycling restricts its practical application.Designing a low-cost,accessible robust network binder is a facile and effective approach to suppress the volume change effect and achieve the commercial application of Si anodes.Different previous studies focused on the network binder macromolecule main chain,this manuscript pays attention to the study of small-molecule cross-linker.Herein,cross-linked network binders using alginate acid and two kinds of cross-linkers,i.e.,D-sorbitol and isosorbide(Alg-DS and Alg-IS binders)are synthesized.It was found that not only the chemical structure of the cross-linker but also the physicochemical property,such as melting point affect greatly the mechanical properties of the network binder.As a result,the Si anode with an Alg-DS binder dried below the melting point of DS shows the best cycling stability with a high capacity of 2249.8 mA·h/g and a retention rate as high as 95.9%after 100 cycles.This study gives a new view to design robust network binders for stable Si anodes.WANG Dong LI Zhenwei ZHANG Qian LIU Jie YANG Yu HAN Jishu WANG Lei 2021Chemical Research in Chinese Universities2021,37,2:0
5Efficient flower-like ZnSe/Cu_(0.08)Zn_(0.92)S photocatalyst for hydrogen production application显示文摘Photocatalytic hydrogen production utilizing abundant solar energy to produce high-calorie, clean, and pollution-free hydrogen is an important approach to solving environmental and resource problems. In this work, a high-efficiency flower-like ZnSe/Cu_(0.08)Zn_(0.92)S photocatalyst was constructed through element doping and the formation of a Z-scheme heterojunction. The synergistic effect of Cu doping and the built-in electric field in the heterojunction enhanced light absorption and utilization by the ZnSe/Cu_(0.08)Zn_(0.92)S microflowers, accelerated the separation and transfer of photogenerated electrons and effectively inhibited electron–hole recombination. Thus the photocatalytic hydrogen production ability of the ZnSe/Cu_(0.08)Zn_(0.92)S microflowers was increased significantly. The highly stable ZnSe/Cu_(0.08)Zn_(0.92)S microflowers could provide excellent catalysis of photocatalytic hydrogen production.Ying Wang Yue Han Ruiyang Zhao Jishu Han Lei Wang 2023Frontiers of Chemical Science and Engineering2023,17,9:0
