order to meet the increasing demands of energy consumption in the next
decades (eg. more electric vehicles to realize a clean urbanization),
material scientists worldwide are working on efficient, low-cost and
low-toxic materials for energy harvesting, conversion and storage from
clean energy sources. Suitable functional materials should be explored
and utilized for relevant energy storage and conversion devices to
address those concerns. However, the current materials are usually
composed of single constituent or in hybrids of binary inorganic
components but with low 苹果平板 areas. The poor electroactivity with
less active sites may further deteriorate the electrochemical
performances of the electrodes. Our strategy is to develop low-cost
transition metal oxide/sulfide based materials to enhance the
electroactivity as well as the electrochemical active 平板电脑 area
(EASA), because the hybridization of two or more components affords the
opportunity to engineer the electronic and/or 三星平板 structures. In
addition, optimization of 平板电脑 structures (such as fabrication of
hollow or core-shell hierarchical structures) of nanostructures may
bring about extra active sites, probably further prompting the
electrochemical performances.报告人简单介绍:Dr. Zhu graduated with a BSc in
Materials Chemistry and MSc in Biomedical Engineering from Sichuan
University. He then went to Singapore to pursue his PhD degree at
Nanyang Technological University in 二零零六. Upon completion of his PhD in
20一三, he worked as a postdoctoral researcher in National University of
Singapore. After a three-year postdoctoral research, he joined Central
South University in 20壹七 to serve as a full-time professor. His research
work is centered on the development of nanostructured functional
materials for energy storage and conversion, such as lithium/sodium ion
batteries, supercapacitors, and photo/electro-catalysis. So far, he has
authored over 40 research papers in international journals including
Adv. Energy Mater., Nano Energy, J. Am. Chem. Soc., Angew. Chem. Int.
Ed., J. Mater. Chem. A and so on with a total citation over 2000 times
and an H-index of 20.附属类小部件:无

anodic and cathodic deposition are facile, versatile and controllable
methods to fabricate nanostructured materials for various kinds of
applications in sensing, catalysis, and energy conversion and storage.
In this talk, I will focus on the recent work of our group on
electrochemical anodization of metal oxide nanotube arrays and cathodic
deposition of transition metal oxides/hydroxides for energy
applications. In the first part, I will give a brief review on the use
of TiO二 nanotubes and/or photonic crystal nanotubes to direct the
propagation of light (photon management) for enhanced light harvesting
in dye-sensitized solar cells. The technique is also extended to the
anodization of valve metal iron and non-valve metal nickel for energy
storage applications. In the second part of my talk, I will give a few
examples on the electrochemical cathodic deposition of transition metal
oxide/hydroxide nanostructures for applications in supercapacitors and
oxygen evolution reaction.
报告二摘要:在质地钻探领域,制备附近理论强度的资料是颇为狼狈的。大大多筹备较强材质的艺术是依靠调控材质中的缺陷以阻挠位错的移动,然则这种方法具备一点都不小的局限性。比方,工业上采纳的价值观单相飞米晶合金和单相金属玻璃能够享有高强度,可是这几个素材往往在非常的低的应变(小于2%)下便出现温度下跌。其它,借使晶粒尺寸减小至超纳限定(超纳被大家定义为尺寸小于十nm),由于反Hall-Petch效应的效劳,材质会发生越来越软化。在此报告中,将介绍使用结合超纳晶与非晶协同强化成效的编写制定来筹措出一种超纳双相质地,使得这种质地在室温下具有近理想强度并解决了尺寸效应难点。这种超纳双相镁合金系统是经过磁控溅射方法将超纳晶粒均匀地嵌入富镁的无定形壳中,所得超纳双相材料的强度是近乎完美的3.三GPa,那也是到现在强度最大的镁合金。同时,大家提议了壹种强度升高体制,并由本营造立模型实行了剖判。在材质制备进度中变成了3个由直径约6nm且大约无位错的超纳晶相,当应变产生时该超纳晶相阻止了主剪切带的传布,在此外已出现的主剪切带内,嵌入的超纳晶差异和旋转,也便于材质的加重和对抗剪切带的软化效能。在告知的末梢,将介绍超纳双相材质的有个别神秘应用价值。大家信任,这种超纳双相构筑将提供壹种制备全新质感的办法,使其负有杰出的教条、磁性、电子或催化品质。报告人简要介绍:南海涛,新加坡共和国北大大学材质科学大学生,现任加州戴维斯分校大学动用物理系副助教,系学士课程总管。首要研商方向为电介质质感和有着新颖微米结构的新财富材质的筹措,质量特点及物理机制商量。商讨事业曾刊登在列国资深学术期刊Nature
