1Ultrasensitive skin‐like wearable optical sensors based on glass micro/nanofibers显示文摘Electronic skin,a class of wearable electronic sensors that mimic the functionalities of human skin,has made remarkable success in applications including health monitoring,human-machine interaction and electronic-biological interfaces.While electronic skin continues to achieve higher sensitivity and faster response,its ultimate performance is fundamentally limited by the nature of low-frequency AC currents.Herein,highly sensitive skin-like wearable optical sensors are demonstrated by embedding glass micro/nanofibers(MNFs)in thin layers of polydimethylsiloxane(PDMS).Enabled by the transition from guided modes into radiation modes of the waveguiding MNFs upon external stimuli,the skin-like optical sensors show ultrahigh sensitivity(1870 k·Pa^-1),low detection limit(7 mPa)and fast response(10μs)for pressure sensing,significantly exceeding the performance metrics of state-of-the-art electronic skins.Electromagnetic interference(EMI)-free detection of high-frequency vibrations,wrist pulse and human voice are realized.Moreover,a five-sensor optical data glove and a 2×2-MNF tactile sensor are demonstrated.These initial results pave the way toward a new category of optical devices ranging from ultrasensitive wearable sensors to optical skins.Lei Zhang Jing Pan Zhang Zhang Hao Wu Ni Yao Dawei Cai Yingxin Xu Jin Zhang Guofei Sun Liqiang Wang Weidong Geng Wenguang Jin Wei Fang Dawei Di Limin Tong 2020Opto-Electronic Advances2020,3,3:12
2Levels and distribution of polychlorinated biphenyls in the atmosphere close to Chinese Great Wall Station, Antarctica: Results from XAD-resin passive air sampling显示文摘Antarctica is an important research region for assessing persistence and long-range atmospheric transport (LRAT) of persistent organic pollutants (POPs). In this study, XAD-resin passive air sampling was conducted near the Chinese Great Wall Station, Antarctica, during a one-year sampling period in 2009-2010. The air concentrations of polychlorinated biphenyls (PCBs) were at a very low level, with total PCBs in the range of 26.74-45.08 pg m 3. PCB profiles were dominated by tetra-PCBs, tri-PCBs and di-PCBs, indicating LRAT was responsible for the pollutants in the Antarctic atmosphere. The sampling site near the Chinese Great Wall Station did not show higher PCB levels than the other sites, suggesting that PCB sources associated with the Great Wall Station were negligible. PCB-11 is a non-Aroclor congener, which has specific sources compared to other Aroclor PCB congeners. PCB-11 was observed in all air samples, with an average concentration of 1.22 pg m 3. To our knowledge, this study is the first investigation of PCB levels and distribution in the atmosphere around the Chinese Great Wall Station, Antarctica.LI YingMing GENG DaWei HU YongBiao WANG Pu ZHANG QingHua JIANG GuiBin 2012Chinese Science Bulletin2012,57,13:5

6Privacy-Preserving Protocol for Data Stored in the Cloud显示文摘Data storage is an important application of cloud computing. With a cloud computing platform, the burden of local data storage can be reduced. However, services and applications in a cloud may come from different providers, and creating an efficient protocol to protect privacy is critical. We propose a verification protocol for cloud database entries that protects against untrusted service providers. Based on identity-based encryption (IBE) for cloud storage, this protocol guards against breaches of privacy in cloud storage. It prevents service providers from easily constructing cloud storage and forging the signature of data owners by secret sharing. Simulation results confirm the availability and efficiency of the proposed protocol.Hongyi Su Geng Yang Dawei Li 2011ZTE Communications2011,9,2:0

8Enhanced electroreduction of CO_(2)to C_(2+)fuels by the synergetic effect of polyaniline/CuO nanosheets hybrids显示文摘Electrochemically converting CO_(2)to value-added multi-carbon(C_(2+))fuels and chemicals is a favorable way to achieve carbon neutrality.Herein,polyaniline/CuO nanosheets(PANI/CuO NSs)hybrid electrocatalysts are developed in order to achieve superior C_(2+)selectivity by imparting PANI functional component to the CuO NSs.The decorated PANI nanoparticles(NPs)can effectively stabilize the*CO intermediates and increase their coverage on the active Cu sites,which facilitates the C-C coupling to form multi-carbon products.Benefiting from the synergetic effect of PANI and CuO NSs,best Faradaic efficiency(FE)for C_(2+)product up to 66.4%at-1.6 V vs.reversible hydrogen electrode(RHE)in a H-cell measurement and 60.0%at 400 mA·cm^(-2) in a flow cell measurement are demonstrated by PANI/CuO NSs-25 sample.More importantly,the C_(2+)selectivity keeps stable even in a continuous measurement time period of 92 h in H-cell measurement.The present study may provide more insights for designing efficient hybrid materials toward superior C_(2+)production from electrocatalytic CO_(2)reduction.Lian Ma Qinghong Geng Longlong Fan Jun-Xuan Li Dawei Du Junli Bai Cuiling Li 2023Nano Research2023,16,7:0
