论文题目:3D printing of graphene-doped target for “matrix-free” laser desorption/ionization mass spectrometry

论文作者:Dingyi Wang, Xiu Huang, Jie Li, Bin He, Qian Liu, Ligang Hu, Guibin Jiang 

发表日期:17 January 2018 

论文摘要:We report a graphene-doped resin target fabricated via a 3D printing technique for laser desorption/ionization mass spectrometry analysis. The graphene doped in the target acts as an inherent laser absorber and ionization promoter, thus permitting the direct analysis of samples without adding matrix. This work reveals a new strategy for easy designing and fabrication of functional mass spectrometry devices.

论文题目:Multifunctional luminescent magnetic cryocooler in a Gd5Mn2 pyramidal complex

论文摘要:Magnetic cooling is a highly efficient refrigeration technique with the potential of replacing expensive and rare helium-3 in the field of ultra-low temperature cooling. However, the visualization of a cryogen at an extremely low temperature and in a strong magnetic field is challenging, but it is crucial for the precise positioning and in situ thermal probe measurements in potential practical applications. Here, the activation of a red-emissive Mn(II) ion using 3d/4f chemistry produces a luminescent molecule cooler, [Gd5Mn2(LOMe)2(OH)4(Ac)6(MeOH)10Cl2]Cl3·2MeOH (1), with the core of an Mn(II)-anchored heptanuclear [GdIII5MnII2] pyramid. The photoluminescence (PL) of the Mn2+ emission, with a large Stokes shift from 4T1(4G) → 6A1(6S), shows not only a sensitive temperature sensing property but also reversible mechanoluminescence (ML). More attractively, these findings reveal a considerable magnetocaloric effect (MCE) coupled with a tunable emission window, opening up new opportunities in the multifunctional applications of PL, ML, and the MCE involving red-light sources, thermometers, and stress imaging. In particular, this provides a novel resolution to design visualized PL coolers.

论文题目:Heteroporous MoS2/Ni3S2 towards superior electrocatalytic overall urea splitting

论文作者:Fang Li,  Junxiang Chen,  Dafeng Zhang,  Wen-Fu Fu,  Yong Chen,  Zhenhai Wen,  Xiao-Jun Lv

发表日期:21 March 2018

论文摘要:The heteroporous MoS2/Ni3S2 catalyst exhibits excellent electrocatalytic activity for the overall urea splitting with only a cell voltage of 1.45 V at 20 mA cmin 1 M KOH with 0.33 M urea. This value is the best of all the bifunctional urea splitting electrocatalysts, including Pt, reported to date.

论文题目:Photocatalytic oxidation of arylalcohols to aromatic aldehydes promoted by hydroxyl radicals over a CoP/CdS photocatalyst in water with hydrogen evolution

论文作者:Yong Xu, Ling-Zhen Zeng, Zi-Cheng Fu, Cong Li, Zhi Yang, Yong Chen, Wen-Fu Fu

发表日期:22 March 2018

论文摘要:Cobalt phosphide (CoP) combined with CdS was employed as a photocatalyst to oxidize arylalcohols into aromatic aldehydes or ketones in water. This was accompanied by the reduction of water, and the quantitative yield of hydrogen evolution was much higher than the chemical equivalent of hydrogen gas. Electron spin resonance spectroscopy and quenching experiments demonstrated that hydroxyl free radicals, originating from water splitting, promoted the oxidation of arylalcohols, while the holes in the valence band of the photocatalyst were reduced by organic substrates. The overall reaction generates high-value-added organics. This photocatalytic reaction is atom-economical, in accordance with the concept of sustainable development.

论文题目:Interfacial engineering in graphene bandgap

论文作者:Xiaozhi Xu, Chang Liu, Zhanghao Sun, Ting Cao, Zhihong Zhang, Enge Wang, Zhongfan Liu, Kaihui Liu

发表日期:07 March 2018

论文摘要:Graphene exhibits superior mechanical strength, high thermal conductivity, strong light–matter interactions, and, in particular, exceptional electronic properties. These merits make graphene an outstanding material for numerous potential applications. However, a graphene-based high-performance transistor, which is the most appealing application, has not yet been produced, which is mainly due to the absence of an intrinsic electronic bandgap in this material. Therefore, bandgap opening in graphene is urgently needed, and great efforts have been made regarding this topic over the past decade. In this review article, we summarise recent theoretical and experimental advances in interfacial engineering to achieve bandgap opening. These developments are divided into two categories: chemical engineering and physical engineering. Chemical engineering is usually destructive to the pristine graphene lattice via chemical functionalization, the introduction of defects, doping, chemical bonds with substrates, and quantum confinement; the latter largely maintains the atomic structure of graphene intact and includes the application of an external field, interactions with substrates, physical adsorption, strain, electron many-body effects and spin–orbit coupling. Although these pioneering works have not met all the requirements for electronic applications of graphene at once, they hold great promise in this direction and may eventually lead to future applications of graphene in semiconductor electronics and beyond.

论文题目:Graphene aerogels for efficient energy storage and conversion

论文作者:Jiajun Mao, James Iocozzia, Jianying Huang, Kai Meng, Yuekun Lai, Zhiqun Lin

发表日期:08 January 2018

论文摘要:Concerns over air quality reduction resulting from burning fossil fuels have driven the development of clean and renewable energy sources. Supercapacitors, batteries and solar cells serve as eco-friendly energy storage and conversion systems vitally important for the sustainable development of human society. However, many diverse elements influence the performance of energy storage and conversion systems. The overall efficiency of systems depends on the specific structure and properties of incorporated functional materials. Carbon materials, such as graphene, are especially promising for materials development in the energy storage and conversion fields. Graphene, a two-dimensional (2D) carbon material only a single atom thick, has massless Dirac fermions (electron transport is governed by Dirac's equation), displays outstanding electrical conductivity, superior thermal conductivity and excellent mechanical properties. 2D free-standing graphene films and powders have paved the way for promising energy applications. Recently, much effort has been spent trying to improve the number of active sites in electrode materials within 3D network/aerogel structures derived from graphene. This is because graphene aerogels are promising materials for energy systems due to their porous hierarchical structure which affords rapid electron/ion transport, superior chemical and physical stability, and good cycle performance. This review aims to summarize the synthetic methods, mechanistic aspects, and energy storage and conversion applications of novel 3D network graphene, graphene derivatives and graphene-based materials. Areas of application include supercapacitors, Li-batteries, H2 and thermal energy storage, fuel cells and solar cells.

发表日期:21 June 2018

论文摘要:In article number 1800772, Wei Qi and co‐workers report the photo‐induced reconfigurable assembly of nanostructures via the simultaneous non‐covalent and covalent polymerization of a functional ferrocene‐ yrosine (Fc‐Y) molecule. The formed nanostructures exhibit both reducing property for in situ mineralization of gold nanoparticles, and redox activity for superior energy storage capacity. The results offer insights into the dynamic self‐assembly of multifunctional materials with promising applications in catalysis and energy storage.
