论文题目:Highly Active, Nonprecious Electrocatalyst Comprising Borophene Subunits for the Hydrogen Evolution Reaction

论文摘要:Developing nonprecious hydrogen evolution electrocatalysts that can work well at large current densities (e.g., at 1000 mA/cm2: a value that is relevant for practical, large-scale applications) is of great importance for realizing a viable water-splitting technology. Herein we present a combined theoretical and experimental study that leads to the identification of α-phase molybdenum diboride (α-MoB2) comprising borophene subunits as a noble metal-free, superefficient electrocatalyst for the hydrogen evolution reaction (HER). Our theoretical finding indicates, unlike the surfaces of Pt- and MoS2-based catalysts, those of α-MoB2 can maintain high catalytic activity for HER even at very high hydrogen coverage and attain a high density of efficient catalytic active sites. Experiments confirm α-MoB2 can deliver large current densities in the order of 1000 mA/cm2, and also has excellent catalytic stability during HER. The theoretical and experimental results show α-MoB2’s catalytic activity, especially at large current densities, is due to its high conductivity, large density of efficient catalytic active sites and good mass transport property.

论文题目:Solid-State Photoinduced Luminescence Switch for Advanced Anticounterfeiting and Super-Resolution Imaging Applications

论文作者:Qingkai Qi, Chong Li, Xiaogang Liu, Shan Jiang, Zhaochao Xu, Richmond Lee, Mingqiang Zhu, Bin Xu, Wenjing Tian

论文摘要:Solid-state organic photoswitches with reversible luminescence modulation property are highly attractive because of their wide prospects in advanced photonic applications, such as optical data storage, anticounterfeiting and bioimaging. Yet, developing such materials has long been a significant challenge. In this work, we construct an efficient solid-state photoswitch based on a spiropyran-functionalized distyrylanthracene derivative (DSA-2SP) that exhibits exceptional reversible absorption/luminescence modulation ability. Efficient photoswitching between DSA-2SP and its photoisomer DSA-2MC are facilitated by large free volumes induced by nonplanar molecular structures of DSA moieties, as well as the intramolecular hydrogen bonds between the DSA and MC moieties. Consequently, the excellent solid-state photochromic property of DSA-2SP is highly applicable as both anticounterfeiting inks and super-resolution imaging agents.

论文摘要:Synthesis of stable open-shell polyradicaloids including control of intramolecular spin–spin interactions is a challenging topic in organic chemistry and materials science. Herein, we report the synthesis and physical characterization of two series of fluorenyl based macrocyclic polyradicaloids. In one series (FR-MCn, n = 4–6), the fluorenyl radicals are directly linked at 3,6-positions; whereas in the other series (MC-FnAn, n = 3–5), an additional ethynylene moiety is inserted between the neighboring fluorenyl units. To access stable macrocyclic polyradicaloids, three synthetic methods were developed. All of these stable macrocycles can be purified by normal silica gel column chromatography under ambient conditions. In all cases, moderate polyradical characters were calculated by restricted active space spin-flip method due to the moderate intramolecular antiferromagnetic spin–spin interactions. The excitation energies from the low-spin ground state to the lowest high-spin excited state were evaluated by superconducting quantum interference device measurements. Their physical properties were also compared with the respective linear fluorenyl radical oligomers (FR-n, n = 3–6). It is found that the geometry, i.e., the distortional angle and spacer (w or w/o ethynylene) between the neighboring fluorenyl units, has significant effect on their polyradical character, excitation energy, one-photon absorption, two-photon absorption and electrochemical properties. In addition, the macrocyclic tetramers FR-MC4 and MC-F4A4 showed global antiaromatic character due to cyclic π-conjugation with 36 and 44 π-electrons, respectively.

论文题目:Wearable Electronics: A Superhydrophobic Smart Coating for Flexible and Wearable Sensing Electronics

论文作者:Lianhui Li, Yuanyuan Bai, Lili Li, Shuqi Wang, Ting Zhang

发表日期:20 Novemberb,2017

论文摘要:A superhydrophobic smart sensing coating is presented by Ting Zhang and co-workers in article 1702517, which can be integrated on running clothes. The coatings are piezoresistive for wearable strain-sensor applications and superhydrophobic for water repellency, and are thus endowed with highly sensitive and stable sensing performance under wet/corrosive conditions.

论文题目:Mechanoluminescence: Temporal and Remote Tuning of Piezophotonic-Effect-Induced Luminescence and Color Gamut via Modulating Magnetic Field

论文作者:Man-Chung Wong, Li Chen, Gongxun Bai, Long-Biao Huang, Jianhua Hao

发表日期:20 November,2017

论文摘要:A novel physical method is developed to tune light-emitting wavelengths and color. Piezophotonic luminescence from the flexible composites of ZnS: Al, Cu phosphors is tuned by modulating the frequency of the magnetic-field excitation at room temperature, as reported by Jianhua Hao and co-workers in article number 1701945. A new understanding of piezophotonic luminescence and magnetic-optics coupling is thus provided.

论文摘要:Inspired by the common flicking finger motion, Ying Hu, Jiaqin Liu, Wei Chen, and co-workers describe in article number 1704388 a novel soft jumping robot based on the rolled carbon nanotube/polymer bilayer actuator with the two ends serving as thumb and middle finger, respectively. Upon light irradiation, this soft robot can jump up, accompanied by somersaults in the air, due to the energy accumulation and instantaneous release.
