| 1 | Breaking 12% efficiency in flexible organic solar cells by using a composite electrode显示文摘The performance of flexible organic solar cells(OSCs)significantly relies on the quality of transparent flexible electrode.Here,we used silver nanowires(AgNWs)with various weight ratios to dope high-conductive poly(3,4-ethylenedioxythiophene):polystyrene sulfonate(PH1000)to optimize the optical and electronic properties of PH1000 film.A high-quality flexible composite electrode PET/Ag-mesh/PH1000:AgNWs-20 with smooth surface,a low sheet resistance of 6Ω/sq and a high transmittance of 86%at 550-nm wavelength was obtained by doping 20 wt%AgNWs to PH1000(PH1000:AgNWs-20).The flexible OSCs based on the PET/Ag-mesh/PH1000:AgNWs-20 electrode delivered a power conversion efficiency(PCE)of12.07%with an open circuit voltage(Voc)of 0.826 V,a short-circuit current density(Jsc)of 20.90 m A/cm2and a fill factor(FF)of69.87%,which is the highest reported PCE for the flexible indium-tin oxide(ITO)-free OSCs.This work demonstrated that the flexible composite electrodes of PET/Ag-mesh/PH1000:AgNWs are promising alternatives for the conventional PET/ITO electrode,and open a new avenue for developing high-performance flexible transparent electrode for optoelectronic devices. | Guang Zeng Jingwen Zhang Xiaobin Chen Hongwei Gu Yaowen Li Yongfang Li | 2019 | Science China Chemistry2019，62，7： | 9 |

| 3 | 10 Gbps wavelength division multiplexing using UV-A, UV-B, and UV-C micro-LEDs显示文摘Deep ultraviolet(DUV) optical wireless communications have seen increased interest in recent years due to the unique properties of light in this spectral region. However, the reported DUV data rates remain significantly lower than comparable demonstrations at visible wavelengths due to lower modulation bandwidths and/or output power of the sources. Here, we present a wavelength division multiplexing demonstration using three UV microlight-emitting diodes emitting at nominal peak wavelengths of 285, 317, and 375 nm, respectively, each with an emitting area of approximately 1369 μm^(2)(equivalent to circular device pixels of diameter;0 μm). Using orthogonal frequency division multiplexing, data rates of 4.17, 3.02, and 3.13 Gbps were achieved from the 285, 317, and 375 nm devices, respectively, for a combined data rate of 10.32 Gbps transmitted over a distance of 0.5 m. | Daniel M.Maclure Jonathan J.D.McKendry Mohamed Sufyan Islim Enyuan Xie Cheng Chen Xiaobin Sun Xudong Liang Xiaohui Huang Hanaa Abumarshoud Johannes Herrnsdorf Erdan Gu Harald Haas Martin D.Dawson | 2022 | Photonics Research2022，10，2： | 1 |

| 6 | Low-cost polymer acceptors with noncovalently fused-ring backbones for efficient all-polymer solar cells显示文摘The polymerization of fused-ring acceptors(FRAs) to afford their corresponding polymeric acceptors for high-performance all-polymer solar cells(all-PSCs) has achieved remarkable progress in the past few years.However,due to the high degree of synthetic complexity for the monomer,the high-cost of these polymeric acceptors may limit their commercial applications.Thus,it is urgent to develop inexpensive and high-performance polymeric acceptors for all-PSCs.Herein,two novel polymeric acceptors(PBTzO and PBTzO-2F) have been designed and synthesized by copolymerization of noncovalently fused ring acceptors(NFRAs),which were employed in all-PSCs for the first time.Upon introducing the “noncovalently conformational locks(NoCLs)” in the backbone and selective fluorination of the end-group,photophysical and electrical properties,and solidstate packing properties of the NFRAs have been rationally tuned.As a result,the PBDB-T:PBTzO-2F based devices presented an excellent power conversion efficiency(PCE) of 11.04%,much higher than that of PBTzO based ones due to the increased charge generation and extraction,improved hole transfer and carrier mobilities,and reduced energy loss.More importantly,PBTzO-2F exhibited a much lower synthetic complexity(SC) index and higher figure-of-merit(FOM) values than the high-performance fused-ring acceptor based polymer acceptors(FRA-PAs) due to the simpler structures and more effective synthesis.This contribution provided a novel idea to achieve low-cost and high-performance all-PSCs. | Xiaobin Gu Yanan Wei Xingzheng Liu Na Yu Laiyang Li Ziyang Han Jinhua Gao Congqi Li Zhixiang Wei Zheng Tang Xin Zhang Hui Huang | 2022 | Science China Chemistry2022，65，5： | 1 |

| 9 | Antarcticite, a Phase Change Material for ThermalEnergy Storage: Experiments and Simulation显示文摘Antarcticite, a mineral with composition CaCl2·6H2O and structure P321, is an ideal phase change material (PCM) due to the high energy storage density and good thermal conductivity. However, the existence of supercooling and incongruent melting would weaken its thermal properties and then hinder its application. In this paper, based on the cooling curve method and DSC measurement, we experimentally selected the minor SrCl2·6H2O as the nucleator and carboxyl methyl cellulose as the thickening agent, which could significantly reduce supercooling and partly restrain the incongruent melting. Moreover, we incorporated Antarcticite as PCM into building envelopes in four different cases, the simulation of the heat transfer processes showed that the temperature fluctuation could be reduced to about 2℃ in the best case. | GU Xiaobin NIU Jingjing QIN Shan | 2013 | 矿物学报2013，33，S1： | 1 |

| 12 | Enhancing Photovoltaic Performance of Nonfused-Ring Electron Acceptors via Asymmetric End-Group Engineering and Noncovalently Conformational Locks显示文摘By employing the asymmetric end-group engineering,an asymmetric nonfused-ring electron acceptor(NFREA)was designed and synthesized.Compared with the symmetric analogs(NoCA-17 and NoCA-18),NoCA-19 possesses broader light absorption range,more coplanarπ-conjugated backbone,and appropriate crystallinity according to the experimental and theoretical results.The organic solar cells based on J52:NoCA-19 exhibited a power conversion efficiency as high as 12.26%,which is much higher than those of J52:NoCA-17(9.50%)and J52:NoCA-18(11.77%),mainly due to more efficient exciton dissociation,better and balanced charge mobility,suppressed recombination loss,shorter charge extraction time,longer charge carrier lifetimes,and more favorable blend film morphology.These findings demonstrate the great potential of asymmetric end-group engineering in exploring low-cost and high-performance NFREAs. | Bo Liu Congqi Li Xiaobin Gu Yinghui Han Zhixiang Wei Yunhao Cai Xin Zhang Hui Huang Yanping Huo | 2024 | Chinese Journal of Chemistry2024，42，5： | 0 |
| 13 | Genome of the Giant Panda Roundworm Illuminates Its Host Shift and Parasitic Adaptation显示文摘Baylisascaris schroederi,a roundworm(ascaridoid)parasite specific to the bamboofeeding giant panda(Ailuropoda melanoleuca),represents a leading cause of mortality in wild giant panda populations.Here,we present a 293-megabase chromosome-level genome assembly of B.schroederi to infer its biology,including host adaptations.Comparative genomics revealed an evolutionary trajectory accompanied by host-shift events in ascaridoid parasite lineages after host separations,suggesting their potential for transmission and rapid adaptation to new hosts.Genomic and anatomical lines of evidence,including expansion and positive selection of genes related to the cuticle and basal metabolisms,indicate that B.schroederi undergoes specific adaptations to survive in the sharp-edged bamboo-enriched gut of giant pandas by structurally increasing its cuticle thickness and efficiently utilizing host nutrients through gut parasitism.Additionally,we characterized the secretome of B.schroederi and predicted potential drug and vaccine targets for new control strategies.Overall,this genome resource provides new insights into the host adaptation of B.schroederi to the giant panda as well as the host-shift events in ascaridoid parasite lineages.Our findings on the unique biology of B.schroederi will also aid in the development of prevention and treatment measures to protect giant panda populations from roundworm parasitism. | Yue Xie Sen Wang Shuangyang Wu Shenghan Gao Qingshu Meng Chengdong Wang Jingchao Lan Li Luo Xuan Zhou Jing Xu Xiaobin Gu Ran He Zijiang Yang Xuerong Peng Songnian Hu Guangyou Yang | 2022 | Genomics, Proteomics & Bioinformatics2022，20，2： | 0 |
| 14 | Thermosensitive injectable hydrogel loaded with hypoxia-induced exosomes maintains chondrocyte phenotype through NDRG3-mediated hypoxic response显示文摘Current clinical treatments cannot effectively delay the progression of osteoarthritis(OA).Consequently,joint replacement surgery is required for late-stage OA when patients cannot tolerate pain and joint dysfunction.Therefore,the prevention of OA progression in the early and middle stages is an urgent clinical problem.In a previous study,we demonstrated that NDRG3-mediated hypoxic response might be closely related to the development and progression of OA.In this study,an injectable thermosensitive hydrogel was established by cross-linking Pluronic F-127 and hyaluronic acid(HA)for the sustained release of hypoxia-induced exosomes(HExos)derived from adipose-derived mesenchymal stem cells.We demonstrated that for OA at the early and middle stages,the HExos-loaded HP hydrogel could maintain the chondrocyte phenotype by enhancing chondrocyte autophagy,reducing chondrocyte apoptosis,and promoting chondrocyte activity and proliferation through the NDRG3-mediated hypoxic response.This novel composite hydrogel,which could activate the NDRG3-mediated hypoxic response,may provide new ideas and a theoretical basis for the treatment of early-and mid-stage OA. | Xiongbo Song Liling Gu Qiming Yang Jiarui Wu Junrong Chen Xiaobin Tian Li Sun Long Chen | 2023 | Chinese Chemical Letters2023，34，8： | 0 |
| 15 | Engineered nitrogen doping on VO_(2)(B)enables fast and reversible zinc-ion storage capability for aqueous zinc-ion batteries显示文摘Vanadium-based compounds with high theoretical capacities and relatively stable crystal structures are potential cathodes for aqueous zinc-ion batteries(AZIBs).Nevertheless,their low electronic conductivity and sluggish zinc-ion diffusion kinetics in the crystal lattice are greatly obstructing their practical application.Herein,a general and simple nitrogen doping strategy is proposed to construct nitrogen-doped VO_(2)(B)nanobelts(denoted as VO_(2)-N)by the ammonia heat treatment.Compared with pure VO_(2)(B),VO_(2)-N shows an expanded lattice,reduced grain size,and disordered structure,which facilitates ion transport,provides additional ion storage sites,and improves structural durability,thus presenting much-enhanced zinc-ion storage performance.Density functional theory calculations demonstrate that nitrogen doping in VO_(2)(B)improves its electronic properties and reduces the zinc-ion diffusion barrier.The optimal VO_(2)-N400 electrode exhibits a high specific capacity of 373.7 mA h g^(-1)after 100 cycles at 0.1 A g^(-1)and stable cycling performance after 2000 cycles at 5 A g^(-1).The zinc-ion storage mechanism of VO_(2)-N is identified as a typical intercalation/de-intercalation process. | Xin Gu Juntao Wang Xiaobin Zhao Xin Jin Yuzhe Jiang Pengcheng Dai Nana Wang Zhongchao Bai Mengdi Zhang Mingbo Wu | 2023 | Journal of Energy Chemistry2023，，10： | 0 |
| 16 | Combination of S…N and S…Cl Noncovalently Conformational Locks for Constructing High-Planarity and Low-Cost Nonfused-Ring Electron Acceptors显示文摘Comprehensive Summary By employing thiazole and 4-chlorothiazole as the A′units,two A-D-A′-D-A type nonfused-ring electron acceptors(NFREAs)Tz-H and Tz-Cl were designed and synthesized.Replacing thiazole in Tz-H with 4-chlorothiazole can not only remarkably shorten the synthetic route through C—H direct arylation but also enhance molecular planarity with the simultaneous incorporation of S…N and S…Cl noncovalently conformational locks(NoCLs).The photovoltaic devices based on PM6:Tz-Cl exhibited a power conversion efficiency as high as 11.10%,much higher than that of PM6:Tz-H(6.41%),mainly due to more efficient exciton dissociation,better and more balanced carrier mobility,less charge recombination,and more favorable morphology.These findings demonstrate the great potential of NoCLs in achieving low-cost and high-performance NFREAs. | Ziyang Han Congqi Li Xiaobin Gu Xiao Han Sixuan Wang Yanan Wei Jinhua Gao Zhixiang Wei Yunhao Cai Xin Zhang Hui Huang | 2023 | Chinese Journal of Chemistry2023，41，15： | 0 |
| 17 | Insight into the efficiency-stability-cost balanced organic solar cell based on a polymerized nonfused-ring electron acceptor显示文摘Organic solar cells(OSCs)have attracted extensive attention from both academia and industry in recent years due to their remarkable improvement in power conversion efficiency(PCE).However,the Golden Triangle(the balance of efficiency-stability-cost)required for large-scale industrialization of OSCs still remains a great challenge.Here,a new nonfused-ring electron acceptor(NFREA)BF and its polymerized counterpart PBF were designed and synthesized,and their photovoltaic performance,storage stability and material cost were systematically investigated.When blended with a widely-used polymer donor PBDB-T,the PBFbased all-polymer solar cell(all-PSC)displayed a record high PCE of 12.61%for polymerized NFREAs(PNFREAs)with an excellent stability(95.2%of initial PCE after 800 h storage),superior to the BF counterpart.Impressively,PBF-based allPSC possesses the highest industrial figure-of-merit(i-FOM)value of 0.309 based on an efficiency-stability-cost evaluation,in comparison to several representative OSC systems(such as PM6:Y6 and PBDB-T:PZ1).This work provides an insight into the balance of efficiency,stability,and cost,and also indicates that the PNFREAs are promising materials toward the commercial application of OSCs. | Xiaobin Gu Yanan Wei Guanyu Lu Ziyang Han Di Zheng Guanghao Lu Jianqi Zhang Zhixiang Wei Yunhao Cai Xin Zhang Hui Huang | 2023 | Aggregate2023，4，6： | 0 |
| 18 | Cloning,expression and improvement of catalytic activity of alginate lyase by site-directed mutation显示文摘Alginate lyase mainly produces active alginate oligosaccharides(AOS)by degrading alginate viaβ-elimination process.In this study,the Pseudoalteromonas sp.Alg6B alginate lyase-encoding gene alg6B-7 from polysaccharide lyase(PL)-7 family was successfully cloned,sequenced,expressed in Escherichia coli.Based on rational design and amino acid sequence alignment of the alginate lyase from various sources,four positive mutants were obtained.The specific enzyme activities of four mutants I62A,A99K,V132S,and L157T were 38.84%,42.85%,75.8%and 51.83%higher than that of the wild enzyme,respectively.The K_(cat)/K_(m) values of the four mutants were both increased,and the catalytic efficiency of V132S was 1.92-fold higher than that of the wild enzyme,especially.The rational design that was employed in this study achieved the dramatic improvement of catalytic activity,which may provide the application potential in industrial production. | Yu Lu Jianli Zhou Qiuya Gu Wenhua Yang Liu Yang Xiaobin Yu | 2022 | Systems Microbiology and Biomanufacturing2022，2，3： | 0 |
| 19 | Organic Optoelectronic Synapses for Sound Perception显示文摘The neuromorphic systems for sound perception is under highly demanding for the future bioinspired electronics and humanoid robots.However,the sound perception based on volume,tone and timbre remains unknown.Herein,organic optoelectronic synapses(OOSs)are constructed for unprecedented sound recognition.The volume,tone and timbre of sound can be regulated appropriately by the input signal of voltages,frequencies and light intensities of OOSs,according to the amplitude,frequency,and waveform of the sound.The quantitative relation between recognition factor(ζ)and postsynaptic current(I=I_(light)−I_(dark))is established to achieve sound perception.Interestingly,the bell sound for University of Chinese Academy of Sciences is recognized with an accuracy of 99.8%.The mechanism studies reveal that the impedance of the interfacial layers play a critical role in the synaptic performances.This contribution presents unprecedented artificial synapses for sound perception at hardware levels. | Yanan Wei Youxing Liu Qijie Lin Tianhua Liu Song Wang Hao Chen Congqi Li Xiaobin Gu Xin Zhang Hui Huang | 2023 | Nano-Micro Letters2023，15，9： | 0 |
