Unlike the conventional hollow particles, the void space is fully utilized due to the presence of the open pore. As a proof-of-concept, MnO2 nanosheets are in-situ grown on both the outer shell and the inner cavity of HCSO forming sandwich structure via a facile redox method, named MnO2@HCSO composite. Meanwhile, the distance for lithium ion diffusion greatly reduces. When tested as an anode material for lithium ion batteries, MnO2@HCSO composite exhibits increased performance compared to MnO2/HCS composites which use traditional closed HCS as carbon matrix. It can still deliver a specific capacity of 398 mAh g−1 based on the whole mass of composite even when the current density was increased to 5 A g−1. This special designed structure would be extended to different fields, such as sensors and catalyst.}, journal={ELECTROCHIMICA ACTA}, publisher={Elsevier BV}, author={Zang, Jun and Ye, Jianchuan and Qian, Hang and Lin, Yu and Zhang, Xiangwu and Zheng, Mingsen and Dong, Quanfeng}, year={2018}, month={Jan}, pages={783–788} }

Onsite monitoring the mental condition of a driver and forewarning may be a preventive solution to reduce occurrence of drowsiness and potential accidents. Functional near‐infrared spectroscopy (fNIRS) has been successfully utilized in hemodynamics‐interpreted functional activity in preliminary voluntary attention experiments. Here, we monitored hemodynamic alternations using fNIRS upon the prefrontal cortex over 13 volunteers in the course of a 7‐hour driving simulation and evaluated their reaction capability with a voluntary attention test based on Go/NoGo paradigm. A degradation in attention test score (Accuracy/RT) as well as the elevations in oxy‐hemoglobin (Δ[HbO2]) and total hemoglobin (Δ[tHb]) were found significantly correlated with driving duration (Accuracy/RT: r = −0.964, P < 0.001; Δ[HbO2]: r = 0.950, P < 0.001; Δ[tHb]: r = 0.852, P = 0.007). The hemodynamic parameters are in significant inverse correlations with Accuracy/RT (Δ[HbO2]: r = −0.896, p = 0.003; Δ[tHb]: r = −0.844, P = 0.008), indicating the potential to forewarn drivers the attention degradation with onsite fNIRS measurements.}, number={12}, journal={JOURNAL OF BIOPHOTONICS}, author={Li, Ting and Lin, Yu and Gao, Yuan and Zhong, Fulin}, year={2018}, month={Dec} }

Zn1-xMgxO (0.25 ≤ x ≤ 0.5) thin films with c-axis textures were deposited by pulsed laser deposition on platinized sapphire substrates. The films were phase pure wurtzite for MgO concentrations up to 40%; above that limit, a second phase with rocksalt structure evolves with strong {100} texture. With increasing MgO concentration, the out-of-plane (d33,f) and in-plane (e31,f) piezoelectric coefficients increase by 360% and 290%, respectively. The increase in piezoelectric coefficients is accompanied by a 35% increase in relative permittivity. Loss tangent values fall monotonically with increasing MgO concentration, reaching a minimum of 0.001 for x ≥ 0.30, at which point the band gap is reported to be 4 eV. The enhanced piezoelectric response, the large band gap, and the low dielectric loss make Zn1-xMgxO an interesting candidate for thin film piezoelectric devices, and demonstrate that compositional phase transformations provide opportunities for property engineering.}, number={4}, journal={Applied Physics Letters}, publisher={AIP Publishing}, author={Kang, Xiaoyu and Shetty, Smitha and Garten, Lauren and Ihlefeld, Jon F. and Trolier-McKinstry, Susan and Maria, Jon-Paul}, year={2017}, month={Jan}, pages={042903} }
