Dinuclear metal synergistic catalysis （DMSC） has been proved powerful in boosting CO2reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework （MOF）,obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center （M-In）,three MOFs with dinuclear homometallic catalytic centers （MM-In）,and three MOFs with dinuclear heterometallic catalytic centers (MM’-In,M/M’=Co（II）,Ni（II）,Zn（II）).It was found that all these MOFs can serve as catalysts for photochemical CO2reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g-1h-1,which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO2reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO2reduction.

提出一种采用国际平整度指数(IRI)评价机场道面平整度的适用性综合分析方法,建立了1/4车辆模型与飞机的动力学模型,采用IRI和飞机重心处竖向加速度(VACGA)作为机场道面平整度的评价指标,利用MATLAB/Simulink建立了IRI和VACGA求解模型;以正弦函数形式的不平整激励模拟机场道面纵断面的微波起伏,在不同振幅、波长和滑行速度条件下定量解析IRI和VACGA的分布特性。计算结果表明:VACGA和IRI均与振幅成正比;IRI的敏感波段为波长1~5m的短波,并在波长为2m时达到最大;飞机在200km·h^(-1)滑行速度下,VACGA随波长的变化呈现3个波峰,并且在波长为15m时达到最大波峰;当飞机在滑行道的滑行速度小于40km·h^(-1)时,VACGA的敏感波段为2.3~7.2m,基本分布在IRI的敏感波段内,说明滑行道平整度的评估可采用IRI,但当飞机在跑道的滑行速度大于60km·h^(-1)时,VACGA敏感波段为6.4~23.6m,分布在IRI不敏感波段内,说明当飞机在跑道的滑行速度较高时,采用IRI检测机场道面平整度是不合理的。

背景与目的:沙培林是一种生物反应调节剂。作为癌症晚期综合治疗的方法之一,其临床疗效已得到肯定。本研究主要评价术前腹腔注射沙培林治疗进展期胃癌的临床疗效。方法:将79例临床评估可行胃癌根治术的患者用随机数字表法随机分为研究组(沙培林+丝裂霉素C治疗组40例)和对照组(丝裂霉素C治疗组39例)。研究组术前48h向患者腹腔内注入沙培林5KE(1KE相当于0.1mg的干链球菌+2700u的青霉素),手术关腹前腹腔内注入4mg丝裂霉素C;对照组于手术关腹前腹腔内注入4mg丝裂霉素C。结果:两组患者均无手术死亡,均未发生十二指肠残端瘘。研究组中发生吻合口瘘和切口裂开的各1例,对照组仅1例发生切口裂开。两组手术并发症的发生率差异无统计学意义(P>0.05)。研究组患者术后3年生存率为76.5%,对照组为49.4%,两组之间的差异有统计学意义(P<0.05)。结论:术前48h腹腔注射沙培林能显著提高胃癌根治术患者术后的3年生存率,且不增加手术并发症的发生率,具有一定的临床应用价值。

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).

Metallic nanoparticles with excellent size controllability and high loading rate are obtained via ultrafast high temperature shock *** Bi/CNRs-15 electrode exhibits an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 degrees C, while the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 degrees C.A novel strategy of high-rate activation is proposed to obtain high capacity and superior stability at low temperature by creating new active sites for interfacial reaction. Sodium-ion batteries have emerged as competitive substitutes for low-temperature applications due to severe capacity loss and safety concerns of lithium-ion batteries at - 20 degrees C or lower. However, the key capability of ultrafast charging at ultralow temperature for SIBs is rarely reported. Herein, a hybrid of Bi nanoparticles embedded in carbon nanorods is demonstrated as an ideal material to address this issue, which is synthesized via a high temperature shock method. Such a hybrid shows an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 degrees C, outperforming all reported SIB anode materials. Coupled with a Na3V2(PO4)3 cathode, the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 degrees C. Based on this work, a novel strategy of high-rate activation is proposed to enhance performances of Bi-based materials in cryogenic conditions by creating new active sites for interfacial reaction under large current.
