Photoelectrochemical(PEC)technique represents a promising approach to chemical transformation by harvesting sustainable solar *** the wide applications of PEC systems such as environmental remediation and solar energy conversion,the reported PEC reactions are dominated by the radical-based processes that are initiated by the single electron transfer between photo-induced carriers and adsorbed species on photoelectrode surface[1,2].For instance,hydroxyl radicals are often involved in the PEC oxidation *** well known,it is a grand challenge to control the formation and evolution rates of radicals,which inevitably leads to the unsatisfactory product selectivity of PEC ***,such a circumstance brings about a question to the research community whether a different mechanism can be established to sustain efficient and selective ***,based on their previous findings on PEC water oxidation[3,4],Zhao and coworkers[5]reported that many substrates can be oxidized in an oxygen atom transfer(OAT)pathway,a non-radical two electron process,to oxygenated products byα-Fe2O3 photoanodes.

Nanomechanics of graphene

National Science Review 2019年第2期6卷 324-348页

作者： yujie Wei Ronggui Yang The State Key Laboratory of Nonlinear Mechanics (LNM) Institute of Mechanics Chinese Academy of Sciences School of Engineering Sciences University of Chinese Academy of Sciences Department of Mechanical Engineering University of Colorado

The super-high strength of single-layer graphene has attracted great interest. In practice, defects resulting from thermodynamics or introduced by fabrication, naturally or artificially, play a pivotal role in the mechanical behaviors of graphene. More importantly, high strength is just one aspect of the magnificent mechanical properties of graphene: its atomic-thin geometry not only leads to ultra-low bending rigidity,but also brings in many other unique properties of graphene in terms of mechanics in contrast to other carbon allotropes, including fullerenes and carbon nanotubes. The out-of-plane deformation is of a ’soft’ nature, which gives rise to rich morphology and is crucial for morphology control. In this review article, we aim to summarize current theoretical advances in describing the mechanics of defects in graphene and the theory to capture the out-of-plane deformation. The structure–mechanical property relationship in graphene, in terms of its elasticity, strength, bending and wrinkling, with or without the influence of imperfections, is presented.

Granular packing as model glass formers

Chinese Physics B 2017年第1期26卷 1-9页

作者： yujie Wang Department of Physics and Astronomy Shanghai Jiao Tong University Shanghai 200240 China Materials Genome Initiative Center Shanghai Jiao Tong University Shanghai 200240 China

Static granular packings are model hard-sphere glass formers. The nature of glass transition has remained a hotly debated issue. We review recent experimental progresses in using granular materials to study glass transitions. We focus on the growth of glass order with five-fold symmetry in granular packings and relate the findings to both geometric frustration and random first-order phase transition theories.

基于减污降碳协同视角构建美丽中国建设绩效评估体系,采用超效率SBM模型定量分析长三角城市群2011—2021年美丽中国建设绩效的时空特征,并进一步构建Dagum基尼系数分解模型探究其空间差异来源。研究发现:(1)长三角城市群美丽中国建设绩效在研究期内总体呈波动上升趋势,且绩效值的分布趋于向高水平区间集中。(2)长三角城市群的美丽中国建设绩效的空间差异显著,总体呈现东高西低、南高北低的分布格局。南京、杭州、合肥、上海等城市群中心城市美丽中国建设绩效在研究期内的提升幅度最大,而马鞍山、铜陵等传统资源型城市在推动美丽中国建设时面临较大压力。(3)省际差异是造成长三角城市群内部美丽中国建设绩效空间分异的主要原因,且其贡献率在研究期内由46.98%上升至72.23%,其中,苏-皖组间差异是省际差异的主要来源。据此提出推进长三角城市群构建美丽中国建设先行区的对策建议。
