| 1 | Refinement of TiB_(2)Powders with High-speed Planetary Mill and Its Effect on TiB_(2)Sinterability显示文摘Titanium diboride ceramic was produced via spark plasma sintering(SPS)using finer TiB_(2)powder made by high-speed planetary ball milling.The effects of ball milling parameters on the composites and particle size of TiB_(2)powder were investigated.It was shown that the average particle size of TiB_(2)powder decreased from 5.8 to 1.59μm and the wear rate of WC balls was 1.58 wt%,when the ball-to-powder weight ratio(BPR),the rotary speed and milling time and were 10:1,600 rpm and 20 min,respectively.The content of WC in TiB_(2)powder can be limited below 4.58 vol%by optimizing the milling conditions.The sintering temperature of TiB_(2)powder milled can be decreased obviously,and the mechanical properties are evidently improved and the microstructure becomes more homogeneous when the powder of TiB_(2)becomes finer.The relative density,hardness,bending strength,and fracture toughness of the TiB_(2)ceramic fabricated at 1700℃reach the optimal values,which are 98.13%,19.14 GPa,756 MPa,and 5.71 MPa·m~(1/2),respectively.The decrease of TiB_(2)particle size and the introduction of WC are the potential reasons for the improvement of TiB_(2)ceramic performance. | 黄啟伟 AI Ruomeng BAI Wenhui HE Qianglong WANG Aiyang HU Lanxin 王为民 | 2021 | Journal of Wuhan University of Technology(Materials Science)2021，36，3： | 1 |

| 3 | H_(2)O_(2) actuated molybdenum oxide nanodots:Multi-enzyme-like activities,leverage of Fenton reaction,and dual-mode sensitive detection of alendronate sodium显示文摘Unexpected benefits to the catalytic performance of materials often originate from the presence of surface defects.Here,novel Dpenicillamine modified molybdenum oxide nanodots,with abundant oxygen vacancy defects,were fabrication by a mild,simple,and cost-effective method.Ultraviolet–visible(UV–Vis)absorption spectra analysis showed that the nanodots had peroxidaselike and catalase-like activities.The reactive oxygen species were probed by electronic paramagnetic resonance technique and spectroscopic methods,demonstrating that the nanodots also had oxidase-like activity.Interestingly,the peroxidase-like activity of nanodots was synergistically enhanced in the presence of ferrous ions or ferric ions.Remarkably,less than nanomolar levels of ferrous ions were required to display this phenomenon,meaning Fenton reagent acted as leverage.Based on this,a sensitive colorimetric and fluorescent dual-mode sensor for alendronate sodium was developed.The linear ranges for colorimetric and fluorescence analysis were 0.2–2.5 and 0.2–2.0μM,with detection limits of 31.21 and 71.84 nM,correspondingly.The method has a simple large-scale material preparation process with higher sensitivity and shorter reaction time,which can inspire and enlighten the design of nanozyme sensors. | Siqi Wang Yao Jin Wenhui Ai Xiufeng Wang Zhiqing Zhang Ting Zhou Guodong Zhang Fang Wang | 2023 | Nano Research2023，16，10： | 1 |

| 5 | Determining the contribution of Mo single atoms components in MoO_(2)nanocatalyst in transfer hydrogenation显示文摘Nanocatalysts are likely to contain undetected single-atom components,which may have been ignored but have significant effect in catalytic reactions.Herein,we report a catalyst composed of Mo single atoms(SAs)and MoO_(2)nanoparticles(NPs)(MoSAs-MoO_(2)@NC),which is an exact model to understand how the SAs contribute to the nanocatalyst.Both experimental results and the density functional theory calculations reveal that Mo SAs on nitrogen-doped carbon provides the reaction zone for nitro reduction,while MoO_(2)is the active site for decomposing hydrazine hydrate to produce H*.Thanks to the synergy between Mo SAs and MoO_(2)NPs,this catalyst exhibits noble metal-like catalytic activity(100%conversion at 4 min)for the dechlorination-proof transfer hydrogenation.Additionally,the hydrogen migration on the catalyst is verified by the electrochemical tests in the absence of a hydrogen source.This work provides a model for further study on the coexistence of single atoms in nanoparticle catalysts. | Ze-Nan Hu Yongjian Ai Yan Zhao Yiming Wang Kelong Ding Wenhui Zhang Rongxiu Guo Xinyue Zhang Xiangbin Cai Ning Wang Jianshe Hu Qionglin Liang Hongyang Liu Fei Huang Limin Wu Jiangwei Zhang Hong-bin Sun | 2023 | Nano Research2023，16，2： | 0 |
