| 1 | Solute manipulation enabled band and defect engineering for thermoelectric enhancements of SnTe显示文摘With years of development, SnTe as a homologue of PbTe has shown great potentialfor thermoelectric applications in p-type conduction, and the most successfulstrategy is typified by alloying for maximizing the valence band degeneracy.Among the known alloy agents, MnTe has been found to be one of the most effectiveenabling a band convergence for an enhancement in electronic performance ofSnTe, yet its solubility of only ~15 at% unfortunately prevents a full optimizationin the valence band structure. This work reveals that additional PbTe alloying notonly promotes the MnTe solubility to locate the optimal valence band structure butalso increases the overall substitutional defects in the material for a substantialreduction in lattice thermal conductivity. In addition, PbTe alloying simultaneouslyoptimizes the carrier concentration due to the cation size effect. These features allenabled by such a solute manipulation synergistically lead to a very high thermoelectricfigure of merit, zT of ~1.5 in SnTe with a 20 at% MnTe and a 30 at% PbTealloying (Sn0.5Mn0.2Pb0.3Te), demonstrating the effectiveness of solute manipulationfor advancing SnTe and similar thermoelectrics. | Zhichao Yao Wen Li Jing Tang Zhiwei Chen Siqi Lin Kanishka Biswas Alexander Burkov Yanzhong Pei | 2019 | InfoMat2019，1，4： | 3 |
| 2 | pH- and H_(2)O_(2)-sensitive drug delivery system based on sodium xanthate:Dual-responsive supramolecular vesicles from one functional group显示文摘Nano-drug delivery systems with multiple stimulus-responsive capabilities have superior response performance and efficient drug release.Nevertheless,it is sophisticated to construct multiple stimulus-responsive systems where the two or more functional groups need to be introduced simultaneously.Xanthate,one functional group with pH and H2O2 stimulus responsiveness,has significant potential applications for building dual-responsive drug delivery system.Herein,we present a novel dual stimuli-responsive supramolecular drug delivery system by using sodium xanthate derivative(SXD)as guest molecule and quaternary ammonium capped pillar[5]arene(QAP5)as host molecule through host-guest interaction on the basis of electrostatic interaction.The amphiphile QAP5⊃SXD could self-assemble into vesicles to efficiently load the anti-cancer drug DOX.The experimental results showed that QAP5⊃SXD nanoparticles could achieve efficient drug delivery and controlled release in the tumor microenvironment.Cytotoxicity experiments proved that DOX@QAP5⊃SXD nanoparticles could significantly improve the anticancer efficiency of free DOX on cancer cells.The present study provides an efficient strategy to develop supramolecular nanocarriers with dual-responsiveness in one functional group for controlled drug release. | Ziyan Shen Ning Ma Feng Wang Jiaming Ren Chenxi Hou Shuang Chao Yuxin Pei Zhichao Pei | 2022 | Chinese Chemical Letters2022，33，10： | 1 |
| 3 | Facile fabrication of branched-chain carbohydrate chips for studying carbohydrate-protein interactions by QCM biosensor显示文摘A novel approach for fabricating branched-chain(BC) carbohydrate chips to study carbohydrate-protein interactions using Quartz Crystal Microbalance(QCM) biosensor was developed. This approach utilizes functional alkynyl-branch molecule modified chip surfaces, which through the terminal alkynyl group for covalent linking of unprotected azide-carbohydrates. The unprotected azide-carbohydrates were syhthesized in one-step using 2-azido-1,3-dimethyl-imidazolinium as catalyst, avoiding complex chemical modifications. Additionally, the branch surface modified with the carbohydrates not only supplies more specific binding site but also reveals significant cluster effect. To exemplify the sugar cluster effect on BC carbohydrate chips, BC Galactose and Mannose chips prepared in this work were used to determine carbohydrate-lectin interactions using QCM biosensor. The results clearly showed that BC chip significantly improves the detection sensitivity compared with the straight-chain(SC) chip. More importantly, the BC galactose chip sensitivity was enhanced 40% compared with the SC galactose chip. | Yuchao Lu Siyu Song Chenxi Hou Shuang Pang Xueming Li Xiaowen Wu Chen Shao Yuxin Pei Zhichao Pei | 2018 | Chinese Chemical Letters2018，29，1： | 1 |
| 4 | The First High-quality Reference Genome of Sika Deer Provides Insights into High-tannin Adaptation显示文摘Sika deer are known to prefer oak leaves,which are rich in tannins and toxic to most mammals;however,the genetic mechanisms underlying their unique ability to adapt to living in the jungle are still unclear.In identifying the mechanism responsible for the tolerance of a highly toxic diet,we have made a major advancement by explaining the genome of sika deer.We generated the first high-quality,chromosome-level genome assembly of sika deer and measured the correlation between tannin intake and RNA expression in 15 tissues through 180 experiments.Comparative genome analyses showed that the UGT and CYP gene families are functionally involved in the adaptation of sika deer to high-tannin food,especially the expansion of the UGT family 2 subfamily B of UGT genes.The first chromosome-level assembly and genetic characterization of the tolerance to a highly toxic diet suggest that the sika deer genome may serve as an essential resource for understanding evolutionary events and tannin adaptation.Our study provides a paradigm of comparative expressive genomics that can be applied to the study of unique biological features in non-model animals. | Xiumei Xing Cheng Ai Tianjiao Wang Yang Li Huitao Liu Pengfei Hu Guiwu Wang Huamiao Liu Hongliang Wang Ranran Zhang Junjun Zheng Xiaobo Wang Lei Wang Yuxiao Chang Qian Qian Jinghua Yu Lixin Tang Shigang Wu Xiujuan Shao Alun Li Peng Cui Wei Zhan Sheng Zhao Zhichao Wu Xiqun Shao Yimeng Dong Min Rong Yihong Tan Xuezhe Cui Shuzhuo Chang Xingchao Song Tongao Yang Limin Sun Yan Ju Pei Zhao Huanhuan Fan Ying Liu Xinhui Wang Wanyun Yang Min Yang Tao Wei Shanshan Song Jiaping Xu Zhigang Yue Qiqi Liang Chunyi Li Jue Ruan Fuhe Yang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，1： | 1 |

| 9 | Machine learning accelerated carbon neutrality research using big data-from predictive models to interatomic potentials显示文摘Carbon neutrality has been proposed as a solution for the current severe energy and climate crisis caused by the overuse of fossil fuels, and machine learning(ML) has exhibited excellent performance in accelerating related research owing to its powerful capacity for big data processing. This review presents a detailed overview of ML accelerated carbon neutrality research with a focus on energy management, screening of novel energy materials, and ML interatomic potentials(MLIPs), with illustrations of two selected MLIP algorithms: moment tensor potential(MTP) and neural equivariant interatomic potential(NequIP). We conclude by outlining the important role of ML in accelerating the achievement of carbon neutrality from global-scale energy management, unprecedented screening of advanced energy materials in massive chemical space, to the revolution of atomicscale simulations of MLIPs, which has the bright prospect of applications. | WU LingJun XU ZhenMing WANG ZiXuan CHEN ZiJian HUANG ZhiChao PENG Chao PEI XiangDong LI XiangGuo MAILOA Jonathan P HSIEH Chang-Yu WU Tao YU Xue-Feng ZHAO HaiTao | 2022 | Science China(Technological Sciences)2022，65，10： | 0 |
| 10 | J-aggregation of photosensitizers leads to an ultrahigh drug-loading system for targeted delivery显示文摘Drug loading capacity is very important in the construction of targeted drug delivery systems(TDDSs)for the improvement of drug delivery efficiency.However,the drug-loading capacity of most nanomaterials is non-idealistic,and developing the high drug-loading TDDSs is still a critical challenge.In this work,an ultrahigh loading system(denoted as HMPB_(2))was prepared via J-aggregation of an aza-boron dipyrromethene derivative(Bod)by using hollow MnO_(2)modified with glucosamine pillar[5]arene as a carrier,which was demonstrated to have typical J-aggregate absorption of Bod,specific cancer cells targeting ability,negligible dark cytotoxicity,and potent phototoxicity.This work provides a successful example to construct an ultrahigh drug-loading system via J-aggregation for targeted delivery. | Yun Qu Wenjuan Jin Yichen Wan Zhichao Pei Yuxin Pei | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
