4Recent advances in designing conductive hydrogels for flexible electronics显示文摘Flexible electronics have emerged as an exciting research area in recent years,serving as ideal interfaces bridging biological systems and conventional electronic devices.Flexible electronics can not only collect physiological signals for human health monitoring but also enrich our daily life with multifunctional smart materials and devices.Conductive hydrogels(CHs)have become promising candidates for the fabrication of flexible electronics owing to their biocompatibility,adjustable mechanical flexibility,good conductivity,and multiple stimuli-responsive properties.To achieve on-demand mechanical properties such as stretchability,compressibility,and elasticity,the rational design of polymer networks via modulating chemical and physical intermolecular interactions is required.Moreover,the type of conductive components(eg,electron-conductive materials,ions)and the incorporation method also play an important role in the conductivity of CHs.Electron-CHs usually possess excellent conductivity,while ion-CHs are generally transparent and can generate ion gradients within the hydrogel matrices.This mini review focuses on the recent advances in the design of CHs,introducing various design strategies for electron-CHs and ion-CHs employed in flexible electronics and highlighting their versatile applications such as biosensors,batteries,supercapacitors,nanogenerators,actuators,touch panels,and displays.Qiongyao Peng Jingsi Chen Tao Wang Xuwen Peng Jifang Liu Xiaogang Wang Jianmei Wang Hongbo Zeng 2020InfoMat2020,2,5:8
5Stratigraphy of the Triassic-Jurassic Boundary Successions of the Southern Margin of the Junggar Basin,Northwestern China显示文摘The Triassic-Jurassic(Tr-J) boundary marks a major extinction event,which(~200 Ma) resulted in global extinctions of fauna and flora both in the marine and terrestrial realms.There prevail great challenges in determining the exact location of the terrestrial Tr-J boundary,because of endemism of taxa and the scarcity of fossils in terrestrial settings leading to difficulties in linking marine and terrestrial sedimentary successions.Investigation based on palynology and bivalves has been carried out over a 1113 m thick section,which is subdivided into 132 beds,along the Haojiagou valley on the southern margin of the Junggar Basin of the northern Xinjiang,northwestern China.The terrestrial Lower Jurassic is conformably resting on the Upper Triassic strata.The Upper Triassic covers the Huangshanjie Formation overlaid by the Haojiagou Formation,while the Lower Jurassic comprises the Badaowan Formation followed by the Sangonghe Formation.Fifty six pollen and spore taxa and one algal taxon were identified from the sediments.Based on the key-species and abundance of spores and pollen,three zones were erected:the Late Triassic(Rhaetian) Aratrisporites-Alisporites Assemblage,the Early Jurassic(Hettangian) Perinopollenites-Pinuspollenites Assemblage,and the Sinemurian Perinopollenites-Cycadopites Assemblage.The Tr-J boundary is placed between bed 44 and 45 coincident with the boundary between the Haojiagou and Badaowan formations.Beds with Ferganoconcha(?),Unio-Ferganoconcha and Waagenoperna-Yananoconcha bivalve assemblages are recognized.The Ferganoconcha(?) bed is limited to the upper Haojiagou Formation, Unio-Ferganoconcha and Waagenoperna-Yananoconcha assemblages are present in the middle and upper members of the Badaowan Formation.The sedimentary succession is interpreted as terrestrial with two mainly lake deposit intervals within Haojiagou and Badaowan formations,yielding fresh water algae and bivalves.However,the presence of brackish water algae Tasmanites and the marine-littoral facies bivalve Waagenoperna from the Badaowan Formation indicate that the Junggar Basin was influenced by sea water caused by transgressions from the northern Tethys,during the Sinemurian.SHA Jingeng Vivi VAJDA PAN Yanhong Linda LARSSON YAO Xiaogang ZHANG Xiaolin WANG Yaqiong CHENG Xiansheng JIANG Baoyu DENG Shenghui CHEN Siwei PENG Bo 2011Acta Geologica Sinica(English Edition)2011,85,2:7
6Shape Control of Doped Semiconductor Nanocrystals (d-Dots)显示文摘Formation of Mn2+-doped ZnSe quantum dots(Mn:ZnSe d-dots)with both branched and nearly spherical shapes has been studied.Structure analysis indicates that the Mn2+dopants were localized in the core of a branched nanocrystal.The growth of branched d-dots,rather than spherical ones,was achieved by simply varying the concentration of two organic additives,fatty acids,and fatty amines.The photoluminescence properties of the branched nanocrystals were explored and compared with those of the nearly spherical particles.Ranjani Viswanatha David M.Battaglia Mark E.Curtis Tetsuya D.Mishima Matthew B.Johnson Xiaogang Peng 2008Nano Research2008,1,2:7

10MnO_(2) cathode materials with the improved stability via nitrogen doping for aqueous zinc-ion batteries显示文摘The research and exploration of manganese-based aqueous zinc-ion batteries have been controversial of cycle stability and mechanism investigation,thus improving the stability and exploring storage mechanism are still the most main issue.Defect engineering has become an effective method to improve cycle stability.Herein,a nitrogen-doped ε-MnO_(2)(MnO_(2)@N)has been prepared using electrochemical deposition and heat treatment under nitrogen atmosphere.As the cathode for zinc-ion batteries,the capacity retention rate of MnO_(2)@N cathode is close to 100%after 500 cycles at 0.5 A g^(-1),while the capacity retention rate for the initial MnO_(2) cathode is 62%.At 5 A g^(-1),the capacity retention rate of MnO_(2)@N cathode is 83%after 1000 cycles,which is much higher than the 27%capacity retention rate for the original MnO_(2) cathode.And it can be found that the oxygen vacancies increase after nitrogen doping,which can improve the conductivity of the MnO_(2)@N cathode.Also,there is Mn-N bond in MnO_(2)@N,which can enhance the electrochemical stability of MnO_(2)@N cathode.In addition,the electrochemical mechanism of MnO_(2)@N cathode has been explored by the CV,GCD and GITT tests.It is found that nitrogen doping promotes the intercalation of H^(+) and the corresponding capacity contribution.Compared with the original MnO_(2) cathode,the diffusion coefficient of H^(+) and Zn^(2+) in MnO_(2)@N cathode increases.Also,the reactions during the charging and discharging process are explored through the ex-situ XRD test.And this work may provide some new ideas for improving the stability of manganese-based zinc-ion batteries.Yanan Zhang Yanpeng Liu Zhenhua Liu Xiaogang Wu Yuxiang Wen Hangda Chen Xia Ni Guohan Liu Juanjuan Huang Shanglong Peng 2022Journal of Energy Chemistry2022,31,1:6

13Surface and intrinsic contributions to extinction properties of ZnSe quantum dots显示文摘This work studies extinction properties of ZnSe quantum dots terminated with either Se-surface or Zn-surface(Se-ZnSe or Zn-ZnSe QDs).In addition to commonly observed photoluminescence quenching by anionic surface sites,Se-ZnSe QDs are found to show drastic signatures of Se-surface states in their UV-visible(Vis)absorption spectra.Similar to most QDs reported in literature,monodisperse Zn-ZnSe QDs show sharp absorption features and blue-shifted yet steep absorption edge respect to the bulk bandgap.However,for monodisperse Se-ZnSe QDs,all absorption features are smeared and a low-energy tail is identified to extend to an energy window below the bulk ZnSe bandgap.Along increasing their size,a cyclic growth of ZnSe QDs switches their surface from Zn-terminated to Se-terminated ones,which confirms that the specific absorption signatures are reproducibly repeated between those of two types of the QDs.Though the extinction coefficients per unit of Se-ZnSe QDs are always larger than those of Zn-ZnSe QDs with the same size,both of them approach the same bulk limit.In addition to contribution of the lattice,extinction coefficients per nanocrystal of Zn-ZnSe QDs show an exponential term against their sizes,which is expected for quantum-confinement enhancement of electron-hole wavefunction overlapping.For Se-ZnSe QDs,there is the third term identified for their extinction coefficients per nanocrystal,which is proportional to the square of size of the QDs and consistent with surface contribution.Shangxin Lin Jiongzhao Li Chaodan Pu Hairui Lei Meiyi Zhu Haiyan Qin Xiaogang Peng 2020Nano Research2020,13,3:5
14InAs/InP/ZnSe Core/Shell/Shell Quantum Dots as Near-Infrared Emitters:Bright,Narrow-Band,Non-Cadmium Containing,and Biocompatible显示文摘High quality InAs/InP/ZnSe core/shell/shell quantum dots have been grown by a one-pot approach.This engineered quantum dots with unique near-infrared(NIR)fluorescence,possessing outstanding optical properties,and the biocompatibility desired for in vivo applications.The resulting quantum dots have significantly lower intrinsic toxicity compared to NIR emissive dots containing elements such as cadmium,mercury,or lead.Also,these newly developed ultrasmall non-Cd containing and NIR-emitting quantum dots showed signifi cantly improved circulation half-life and minimal reticuloendothelial system(RES)uptake.Renguo Xie Kai Chen Xiaoyuan Chen Xiaogang Peng 2008Nano Research2008,1,6:4
15One-pot/three-step synthesis of zinc-blende CdSe/CdS core/shell nanocrystals with thick shells显示文摘A one-pot/three-step synthetic scheme was developed for phase-pure epitaxy of CdS shells on zinc-blende CdSe nanocrystals to yield shells with up to sixteen monolayers. The key parameters for the epitaxy were identified, including the core nanocrystal concentration, solvent type/composition, quality of the core nanocrystals, epitaxial growth temperature, type/concentration of ligands, and composition of the precursors. Most of these key parameters were not influential when the synthetic goal was thin-shell CdSe/CdS core/shell nanocrystals. The finalized synthetic scheme was reproducible at an almost quantitative level in terms of the crystal structure, shell thickness, and optical properties.Yuan Niu Chaodan Pu Runchen Lai Renyang Meng Wanzhen Lin Haiyan Qin Xiaogang Peng 2017Nano Research2017,10,4:3
