BACKGROUND Early gastric cancer(EGC)is typically treated with endoscopic submucosal dissection(ESD).However,recurrence may occur after ESD,requiring *** To examine the knowledge,attitude,and practice(KAP)of EGC survivors following ESD regarding gastric cancer *** This cross-sectional study was conducted between June 1,2022 and October 1,2022 in Zhejiang,China.A total of 400 EGC survivors who underwent ESD at the Affiliated Jinhua Hospital,Zhejiang University School of Medicine participated in this study.A self-administered questionnaire was developed to assess KAP monitoring gastric cancer after *** The average scores for KAP were 3.34,23.76,and 5.75 out of 5,30,and 11,*** correlation analysis revealed positive and significant correlations between knowledge and attitude,knowledge and practice,and attitude and practice(r=0.405,0.511,and 0.458,respectively;all P<0.001).Multivariate logistic regression analysis showed that knowledge,attitude,13-24 mo since the last ESD(vs≤12 mo since the last ESD),and≥25 mo since the last ESD(vs≤12 mo since the last ESD)were independent predictors of proactive practice(odds ratio=1.916,1.253,3.296,and 5.768,respectively,all P<0.0001).CONCLUSION EGC survivors showed inadequate knowledge,positive attitude,and poor practices in monitoring recurrences after *** knowledge,positive attitude,and a longer time since the last ESD were associated with practice.

Electrochemical reconstruction: a new perspective on Sn metal-organic complex microbelts as robust anode for lithium storage

Rare Metals 2024年第1期43卷 76-86页

作者： Jin-Ke Shen Nai-teng Wu li-Yuan Wang Gang Jiang Dong-Lei Guo Jin li Gui-Long liu hong-Yu Mi Huan Pang Xian-Ming liu Key Laboratory of Function-oriented Porous Materials of Henan Province College of Chemistry and Chemical EngineeringLuoyang Normal UniversityLuoyang 471934China State Key Laboratory of Chemistry and Utilization of Carbon Based Energy Resources School of Chemical Engineering and TechnologyXinjiang UniversityUrumqi 830046China School of Chemistry and Chemical Engineering Institute for Innovative Materials and EnergyYangzhou UniversityYangzhou 225009JiangsuChina

Tin-based materials with high theoretical capacity and suitable working voltage are ideal anode materials for lithium-ion batteries(liBs). However, to overcome their shortcomings(volume expansion and inferior stability), the preparation processes are usually complicated and expensive. Herein, a tin-based metal-organic complex(tin 1,2-benzenedicarboxylic acid, Sn-BDC)with one-dimensional microbelt morphology is synthesized by a facile, rapid and low-cost co-precipitation method, and served as anode material for liBs without any post-treatment. Sn-BDC exhibits a high reversible capacity with609/440 m Ah·g^(-1) at 50/2000 m A·g^(-1), and robust cycling stability of 856 m Ah·g^(-1) after 200 cycles at 200 m A·g^(-1),which are obviously superior to that of the Sn Ox/C counterparts. Moreover, an electrochemical reconstruction perspective on the lithium storage mechanism of Sn-BDC is proposed by systematic ex-situ characterizations. The reconstructed SnO_(2) replaces Sn-BDC and becomes the active material in the subsequent cycles. As the by-product of the lithiation reaction, the formed li-based metal-organic complex(li-BDC, wrapped around the reconstructed SnO_(2)) plays an important role in alleviating volume expansion and accelerating the charge transfer *** work is beneficial to design and construct the new electrode materials based on the electrochemical reconstruction for advanced liBs.
