| 1 | Optimization of broadband omnidirectional antireflection coatings for solar cells显示文摘Broadband and omnidirectional antireflection coating is generally an effective way to improve solar cell efficiency, because the destructive interference between the reflected and incident light can maximize the light transmission into the absorption layer. In this paper, we report the incident quantum efficiency ηin, not incident energy or power, as the evaluation function by the ant colony algorithm optimization method, which is a swarm-based optimization method. Also, SPCTRL2 is proposed to be incorporated for accurate optimization because the solar irradiance on a receiver plane is dependent on position, season, and time. Cities of Quito, Beijing and Moscow are selected for two-and three-layer antireflective coating optimization over λ = [300,1100] nm and θ = [0°, 90°]. The ηin increases by 0.26%, 1.37% and 4.24% for the above 3 cities, respectively, compared with that calculated by other rigorous optimization algorithms methods, which is further verified by the effect of position and time dependent solar spectrum on the antireflective coating design. | Xia Guo Qiaoli Liu Huijun Tian Ben Li Hongyi Zhou Chong Li Anqi Hu Xiaoying He | 2019 | Journal of Semiconductors2019，40，3： | 4 |
| 2 | Fabrication of flexible AlGaInP LED显示文摘Flexible light-emitting diodes(LEDs)are highly desired for wearable devices,flexible displays,robotics,biomedicine,etc.Traditionally,the transfer process of an ultrathin wafer of about 10–30μm to a flexible substrate is utilized.However,the yield is low,and it is not applicable to thick GaN LED chips with a 100μm sapphire substrate.In this paper,transferable LED chips utilized the mature LED manufacture technique are developed,which possesses the advantage of high yield.The flexible LED array demonstrates good electrical and optical performance. | Qiaoli Liu Yajie Feng Huijun Tian Xiaoying He Anqi Hu Xia Guo | 2020 | Journal of Semiconductors2020，41，3： | 2 |
| 3 | Catch bond-inspired hydrogels with repeatable and loading rate-sensitive specific adhesion显示文摘Biological receptor-ligand adhesion governed by mammalian cells involves a series of mechanochemical pro-cesses that can realize reversible,loading rate-dependent specific interfacial bonding,and even exhibit a counterintuitive behavior called catch bonds that tend to have much longer lifetimes when larger pulling forces are applied.Inspired by these catch bonds,we designed a hydrogen bonding-meditated hydrogel made from acrylic acid-N-acryloyl glycinamide(AA-NAGA)copolymers and tannic acids(TA),which formed repeatable specific adhesion to polar surfaces in an ultra-fast and robust way,but hardly adhered to nonpolar materials.It demonstrated up to five-fold increase in shear adhesive strength and interfacial adhesive toughness with external loading rates varying from 5 to 500 mm min^(-1).With a mechanochemical coupling model based on Monte Carlo simulations,we quantitatively revealed the nonlinear dependence of rate-sensitive interfacial adhesion on external loading,which was in good agreement with the experimental data.Likewise,the developed hydrogels were biocompatible,possessed antioxidant and antibacterial properties and promoted wound healing.This work not only reports a stimuli-responsive hydrogel adhesive suitable for multiple biomedical applications,but also offers an innovative strategy for bionic designs of smart hydrogels with loading rate-sensitive specific adhesion for various emerging areas including flexible electronics and soft robotics. | Zuoying Yuan Xiaocen Duan Xing Su Zhuoling Tian Anqi Jiang Zhuo Wan Hao Wang Pengfei Wei Bo Zhao Xiaozhi Liu Jianyong Huang | 2023 | Bioactive Materials2023，，3： | 1 |
| 4 | Organophosphorus catalytic reaction based on reduction of phosphine oxide显示文摘The special electronic configuration of phosphorus atoms endows organophosphorus reagents with unique chemical properties,which enable them to be used to catalyze various organic reactions,such as the Wittig reaction,Staudinger reaction,Appel reaction and Mitsunobu reaction.However,the catalytic process will be accompanied by the generation of large amounts of phosphine oxide waste,resulting in the reduction of atom utilization of the reaction,and it is difficult to separate the product.Therefore,it is essential to explore a greener and more sustainable organic synthesis route based on the catalytic cycle of phosphine oxide as a model.This paper summarizes the catalytic cycle and recycling of phosphorus with or without reducing agents and reviews the related developments in recent decades:from the addition of stoichiometric strong reducing agents,to the design of ring phosphines with specific structures,to the development of new energy inputs(electrochemistry),to the addition of a series of compounds to activate the P(V)––O double bond,driving the catalytic cycle of phosphine oxide through chemical transformation.This review also points out the development potential of this field in the future,which will promote its development and progress in a greener direction. | Mengyu Pei Anqi Tian Qingqing Yang Nianyu Huang Long Wang Dongsheng Li | 2023 | Green Synthesis and Catalysis2023，4，2： | 0 |
| 5 | Frustrated Lewis pairs in situ formation in B-based porous aromatic frameworks for efficient o-phenylenediamine cyclization显示文摘Benzimidazoles are very important chemical materials in the pharmaceutical industry,and the most common synthetic route is cyclization of o-phenylenediamine with carbon sources,in which utilization of inexpensive and abundant CO_(2)as C1 source is very impressive.Porous aromatic frameworks(PAFs)with highly desired skeletons have attracted great attentions in gas capture and catalysis.Herein,B-based PAF-165 and PAF-166 are designed and synthesized via Friedel-Crafts alkylation reaction,which present high surface areas as well as high stability.Benefiting from the abundant electron-deficient B centers,both PAFs exhibit excellent selective CO_(2)adsorption abilities.The presence of sterically hindered B units in PAFs can act as Lewis acid active sites for the frustrated Lewis pairs(FLPs)in situ formation with ophenylenediamine,thus promoting the synthesis of benzimidazole.The optimal reaction conditions for o-phenylenediamine cyclization with PAF catalysts are explored,and the reaction mechanism is also proposed.This work provides feasible ideas for incorporating FLPs within porous materials as reusable heterogeneous catalysts for CO_(2)capture and conversion. | Anqi Dai Shulin Li Tienan Wang Yuting Yang Yuyang Tian Xiaofei Jing Guangshan Zhu | 2023 | Chinese Chemical Letters2023，34，5： | 0 |
| 6 | Molecular mechanism of lycopene cyclases regulating carotenoids ratio in different branches during tea leaf and flower development显示文摘Carotenoids are essential components in tea quality, contributing to leaf color and aroma. However, little information about carotenoids in different tea cultivars and their biosynthesis regulation mechanism during leaf development is known. Here we analyzed carotenoids by HPLC in the buds and leaves of 113 tea cultivars harvested on the same day. By profile clustering, carotenoids were divided into five groups. Same group cultivars displayed divergence in the total content of carotenoids but a similar molar ratio. To figure out the molecular mechanisms of this phenomenon, we further characterized all functional lycopene cyclases, which are the branch point of the carotenoid biosynthesis pathway. Two β-lycopene cyclases(CsLCYB1 and CsLCYB2) and one ε-lycopene cyclase(CsLCYE1) were cloned. Subcellular localization analysis showed that all cloned CsLCYs were localized in plastids. Enzyme activity assays in E. coli indicated both CsLCYBs catalyzed lycopene into β-carotene, and CsLCYE1 produced δ-carotene and ε-carotene. We found CsLCYB1 and CsLCYE1 predominantly expressed in leaf, while CsLCYB2was mainly expressed during flowering stages. Suppression by antisense oligonucleotides reduced CsLCYB1 and CsLCYE1 transcripts and led to reduction of both β,β-branch and β,ε-branch carotenoids in leaf. The expression levels of CsLCYB1 showed a significant positive correlation withβ,β-branch carotenoids in leaf. Our study provides carotenoid profiles of different tea cultivars, which can assist tea producers in selecting cultivars of interest. Meanwhile, we proposed the molecular mechanism of carotenoids reflecting the tenderness of tea plant leaf from a metabolic flux perspective, and suggested lycopene cyclase that could be applied to the breeding of tea varieties with different branch carotenoids. | Anqi Peng Xiaoyan Tang Yingying Feng Yun Huang Jilai Cui Kai Tian Mengqian Lu Yifan Zhao Yuting Pan Sanjin Wang Yutong Hu Wei Zhao Chuankui Song Qiang Wang | 2023 | Horticultural Plant Journal2023，9，6： | 0 |
| 7 | Mouse model for pangolin-origin coronavirus GX/P2V/2017 infection and cross-protection from COVID-19 ZF2001 subunit vaccine显示文摘Many severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)–related coronaviruses have been discovered,constituting potential threats to human health.However,it remains unclear whether the currently available vaccines are effective against these coronaviruses.Here,we constructed a wild-type mouse model to evaluate pathogenicity of the SARS-CoV-2-related pangolin coronavirus GX/P2V/2017 and neutralization efficacy of the approved tandemrepeat SARS-CoV-2 spike receptor-binding domain(RBD)vaccine ZF2001.We found that ZF2001-induced cross-reactive and cross-neutralizing antibodies against GX/P2V/2017,and the vaccination alleviated the pathological lung damage caused by GX/P2V/2017 in mice.These results indicate that RBD may work as a promising candidate for pan-coronavirus vaccine development. | Xiao Qu Yunfei Jia Na Jia Huahao Fan Anqi Zheng Luoyuan Xia Zhenfei Wang Di Tian Sheng Niu Yu Hu Wenxia Tian Zhihai Chen Yigang Tong Yuwei Gao Wuchun Cao Qihui Wang George Fu Gao | 2023 | hLife2023，1，1： | 0 |
