2Effect of Tm-Er concentration ratio on the photoluminescence of Er-Tm:Al_2O_3 thin films fabricated by pulsed laser deposition显示文摘Er-Tm codoped amorphous aluminum oxide(a-Al2O3)thin films have been prepared by an alternative pulsed laser deposition.The phase structure and the surface of the deposited thin films were characterized by the X-ray diraction(XRD)and scanning electron microscopy(SEM),respectively.Eective photoluminescence(PL)in the region of 350-900 nm was observed when pumped at 325 nm,and the PL performance has been improved by modifying the Tm3 +concentration.With the increasing of[Tm]/[Er]concentra-tion ratio,the intensity of emission of 382 nm and 500 nm bands was improved eectively while that of 765 nm band increased smoothly.Our results suggest that the resonant energy transfer and cross relaxation between Tm3 +and Er 3+play an important role in the evolution of the luminescent response.Bo Zhou Zhisong Xiao Anping Huan Lu Yan Fang Zhu Jinliang Wang Penggang Yin Hao Wang 2008Progress in Natural Science:Materials International2008,18,6:2

4Recent advances in recyclable thermosets and thermoset composites based on covalent adaptable networks显示文摘Recyclable thermosets and thermoset composites with covalent adaptable networks(CANs,or dynamic covalent networks) have attracted considerable attention in recent years due to the combined merits of excellent mechanical and thermal properties,and chemical stabilities of traditional thermosets and recyclable,remoldable,and reprocessable attributes of thermoplastics.In this paper,we present an overview of the current strategies for synthesizing recyclable thermosets based on CANs,which involve recyclability,reprocessability,and possible rehealability.The recent literature examples are categorized based on the underlying controlled-cleavable linkages such as transesterification,DA/retro-DA chemistry,imine bonds,disulfide metathesis,dynamic B-O bonds,hemiaminals/hexahydrotriazines,and acetal linkages.Various degradation and malleability methods and resulting mechanical properties of the recycled thermosets and thermoset composites are presented.The emerging applications of recyclable thermosets and thermoset composites,with emphasis on their usage in adhesives,biomedical materials,wearable devices,coatings,and 3D printing materials,are also illustrated.Finally,a perspective on the challenges and future perspectives is briefly summarized.Yihe Zhang Li Zhang Guotao Yang Yalin Yao Xu Wei Tianchi Pan Juntao Wu Moufeng Tian Penggang Yin 2021Journal of Materials Science & Technology2021,,33:1
5Intrinsic electrochemical activity modulation of MOF-derived C/N-NiCoMn-LDH/Ag electrode for low temperature hybrid supercapacitors显示文摘Layered double hydroxides(LDHs)are promising electrode candidates for supercapacitors.However,lim-itations like inferior cycling stability and unsatisfactory charge storage capability at low temperatures have exerted negative effects on their applications.Herein,a novel synthetic process has been elaborately designed and provided to have the composition and structure of the C/N-NiCoMn-LDH/Ag(C/N-CNMA)delicately regulated.Both the experimental and theoretical researches unveil that the incorporated manganese species and elemental silver could dramatically modulate the bandgap,crystallinity and surface electron structure of the LDH,leading to the remarkable improvement in its conductivity,exposed active sites and intrinsic electrochemical activity,and thus the OH^(*)and O^(*)adsorption free energy could be remarkably optimized,even at low temperatures.In addition,the low crystallinity C/N-CNMA is of great electrochemical compatibility with both the KOH aqueous electrolyte and the isobutyl alcohol(IPA)modulated organohydrogel electrolyte.By means of adjusting the solvation and hydrogen bonding in the electrolytes,the assembled hybrid supercapacitors deliver excellent energy density,power density and cycling stability in the temperature range of-30 to 25℃.Specifically,the gel electrolyte with IPA as the anti-freezing functional additive displays high flexibility and ionic conductivity at low temperatures.Xiaohui Guan Jingyang Chen Enze Zhu Penggang Yin Liu Yang Xin Guan Guangsheng Wang 2023Journal of Materials Science & Technology2023,,19:0
6Interface electronic engineering of molybdenum sulfide/MXene hybrids for highly efficient biomimetic sensors显示文摘Interface regulation plays a key role in the electrochemical performance for biosensors.By controlling the interfacial interaction,the electronic structure of active species can be adjusted effectively at micro and nano-level,which results in the optimal reaction energy barrier.Herein,we propose an interface electronic engineering scheme to design a strongly coupled 1T phase molybdenum sulfide(1T-MoS2)/MXene hybrids for constructing an efficient electrocatalytic biomimetic sensor.The local electronic and atomic structures of the 1T-MoS2/Ti3C2TX are comprehensively studied by synchrotron radiation-based X-ray photoelectron spectroscopy(XPS),as well as X-ray absorption spectroscopy(XAS)at atomic level.Experiments and theoretical calculations show that there are interfacial stresses,atomic defects and adjustable bond-length between MoS2/MXene nanosheets,which can significantly promote biomolecular adsorption and rapid electron transfer to achieve excellent electrochemical activity and reaction kinetics.The 1T-MoS2/Ti3C2TX modified electrode shows ultra high sensitivity of 1.198μA/μM for dopamine detection with low limit of 0.05μM.We anticipate that the interface electronic engineering investigation could provide a basic idea for guiding the exploration of advanced biosensors with high sensitivity and low detection limit.Pengfei Wu Tingting You Qingyuan Ren Hongyan Xi Qingqing Liu Fengjuan Qin Hongfei Gu Yu Wang Wensheng Yan Yukun Gao Wenxing Chen Penggang Yin 2023Nano Research2023,16,1:0

8Peroxidase-like single Fe atoms anchored on Ti_(3)C_(2)T_(x)MXene as surface enhanced Raman scattering substrate for the simultaneous discrimination of multiple antioxidants显示文摘Single-atom nanozymes(SAzymes)are emerging as promising alternatives to mimic natural enzyme,which is due to high atomic utilization efficiency,well-defined geometric,and unique electronic structure.Herein,Fe single atoms supported on Ti_(3)C_(2)T_(x)(Fe-SA/Ti_(3)C_(2)T_(x))with intrinsic peroxidase activity is developed,further constructing a sensitive Raman sensor array for sensing of five antioxidants.Fe-SA/Ti_(3)C_(2)T_(x)shows excellent peroxidase-like performance in catalyzing the oxidation of 3,3',5,5'-tetramethylbenzidine(TMB)with colorimetric reactions.X-ray adsorption fine structure(XAFS)reveals that the electron transport between the Ti_(3)C_(2)T_(x)and Fe atoms occurs along Fe-O-Ti ligands,meanwhile the density functional theory(DFT)calculations confirm the spontaneous dissociation of H_(2)O_(2)and the formation of OH radicals.Furthermore,the peroxidase-like Fe-SA/Ti_(3)C_(2)T_(x)was used as surface enhanced Raman scattering(SERS)substrate of oxidized TMB(TMB+)and achieved satisfied signal amplification performance.Using the blocking effects of free radical reactions,one-off identification of 5 antioxidants,including ascorbic acid(AA),uric acid(UA),glutathione(GSH),melatonin(Mel),and tea polyphenols(TPP),could be realized with this high identifiable catalytic property.This principle could realize 100%distinguish accuracy combined with linear discriminant analysis(LDA)and heat map data analysis.A wide detection concentration ranges from 10^(-8)to 10^(-3)M for five antioxidants was also achieved.Hongyan Xi Hongfei Gu Yurui Han Tingting You Pengfei Wu Qingqing Liu Lirong Zheng Shuhu Liu Qiang Fu Wenxing Chen Yukun Gao Yuting Wang Penggang Yin 2023Nano Research2023,16,7:0
