1In-Situ Synthesis of CQDs/BiOBr Material via Mechanical Ball Milling with Enhanced Photocatalytic Performances显示文摘Designing simple, efficient, and environmentally friendly methods to construct high-efficient photocatalysts is an important strategy to promote the further development of the field of photocatalysis. Herein, flower-like carbon quantum dots(CQDs)/Bi OBr composite photocatalysts have been prepared via in-situ synthesis by mechanical ball milling in the existence of ionic liquid. The CQDs/Bi OBr composites exhibit higher photo-degradation performance for tetracycline(TC) than Bi OBr monomer and the commercial Bi_(2)O_(3) under visible light irradiation. For comparison, the different Br sources and synthetic methods are chosen to prepare Bi OBr and CQDs/Bi OBr composites. Photocatalysts prepared by ball milling and ionic liquid present significantly enhanced photocatalytic performance for removing TC. In addition, the introduction of CQDs could distinctly enhance the photocatalytic performances of pure Bi OBr. The reason is that CQDs as electron acceptor effectively separate electrons and holes and inhibit their recombination. The intermediates during photocatalytic degradation were tested using liquid chromatography-mass spectrometry(LC-MS) and possible degradation pathways were given. During degradation, ·OH, O_(2)^(·-)and h^(+) were identified to be the main active species based on electron spin resonance(ESR) spectra and free radical trapping experiments. A possible mechanism of CQDs/Bi OBr with enhanced photocatalytic performances was further proposed.Xingwang Yan Bin Wang Mengxia Ji Qi Jiang Gaopeng Liu Pengjun Liu Sheng Yin Huaming Li Jiexiang Xia 2022Chinese Journal of Structural Chemistry2022,41,8:1

4Synthesis and Characterization of Novel Biodegradable Poly (butylene succinate-co-triethylene glycol succinate)Copolymers显示文摘Novel biodegradable aliphatic polyesters,poly(butylene succinate-co-triethylene glycol succinate)(P(BS-co-TEGS))and poly(butylene succinate)(PBS),were synthesized through a two-step procedure of esterification and polycondensation with succinic acid and1,4-butanediol/triethylene glycol as raw materials as well as tetrabutyl titanate and diphenylphosphinic acid as the co-catalysts.The chemical structure and molecular weight of the copolymers were characterized by 1~H nuclear magnetic resonance(~1H NMR)and gel permeation chromatography(GPC),respectively.In addition,thermal properties,crystal structure and mechanical properties were also analyzed with various techniques.P(BS-co-TEGS)exhibited more excellent mechanical properties than PBS,especially in elongation at break.Meanwhile,the crystal structure and thermal stability of the P(BS-co-TEGS)have hardly changed.The crystallinity of P(BS-co-TEGS)was lower than that of PBS and decreased with the increase of mole ratio of triethylene glycol.With the increase of TEGS unit molar composition,the melting point(T_m),crystallization temperatures(T_c)and heat of fusion(ΔH_m)of P(BS-co-TEGS)decreased,while glass transition temperature(T_g)increased.Jie Ouyang Hongquan Yin Qingshan Zhang Yunzheng Li Pengjun Yao 2017Journal of Beijing Institute of Technology2017,26,2:0
5The molecular,electrophysiological,and structural changes in the vestibular nucleus during vestibular compensation:a narrative review显示文摘The vestibular system involves high-level sensory and cognitive processes,such as spatial perception,balance control,visual stability,and emotional control.Vestibular dysfunction can induce vertigo,blurred vision,postural imbalance,walking instability,and spatial discomfort,which causes serious damage to health.It has long been known that after peripheral vestibular lesion,vestibular dysfunction may spontaneously recover.This is known as vestibular compensation.However,at least 20%to 30%of patients with vestibular disorders cannot yield vestibular compensation and remain with vestibular dysfunction for the rest of their lives.The exploration of the biological characteristics and regulatory factors of the loss and reestablishment of vestibular function will establish a new understanding of the mechanism of vestibular compensation and provide new tools and strategies for promoting vestibular rehabilitation.We aim to comprehensively review the mechanism of vestibular compensation and discuss future directions in this field.Pengjun Wang Wen Lu Yini Li Haibo Shi Shankai Yin 2021Journal of Bio-X Research2021,4,4:0
