| 1 | Voltage-induced penetration effect in liquid metals at room temperature显示文摘Room-temperature liquid metal is discovered to be capable of penetrating through macro-and microporous materials by applying a voltage.The liquid metal penetration effects are demonstrated in various porous materials such as tissue paper;thick and fine sponges;fabrics;and meshes.The underlying mechanism is that the high surface tension of liquid metal can be significantly reduced to near-zero due to the voltage-induced oxidation of the liquid metal surface in a solution.It is the extremely low surface tension and gravity that cause the liquid metal to superwet the solid surface^leading to the penetration phenomena.These findings offer new opportunities for novel microfluidic applications and could promote further discovery of more exotic fluid states of liquid metals. | Frank F Yun Zhenwei Yu Yahua He Lei Jiang Zhao Wang Haoshuang Gu Xiaolin Wang | 2020 | National Science Review2020，7，2： | 3 |
| 2 | Gas sensing capabilities of TiO_(2) porous nanoceramics prepared through premature sintering显示文摘Pure and noble metal(Pt,Pd,and Au)doped TiO_(2)nanoceramics have been prepared from TiO_(2)nanoparticles through traditional pressing and sintering.For those samples sintered at 550℃,a typical premature sintering occurred,which led to the formation of a highly porous microstructure with a Brunauer-Emmett-Teller(BET)specific surface area of 23 m^(2)/g.At room temperature,only Pt-doped samples showed obvious response to hydrogen,with sensitivities as high as~500 for 1000 ppm H_(2)in N_(2);at 300℃,all samples showed obvious responses to CO,while the responses of noble metal doped samples were much higher than that of the undoped ones.The mechanism for the observed sensing capabilities has been discussed,in which the catalytic effect of Pt for hydrogen is believed responsible for the room-temperature hydrogen sensing capabilities,and the absence of glass frit as commonly used in commercial thick-film metal oxide gas sensors is related to the high sensitivities.It is proposed that much attention should be paid to metal oxide porous nanoceramics in developing gas sensors with high sensitivities and low working temperatures. | Yao XIONG Zilong TANG Yu WANG Yongming HU Haoshuang GU Yuanzhi LI Helen Lai Wah CHAN Wanping CHEN | 2015 | Journal of Advanced Ceramics2015，4，2： | 3 |
| 3 | Nickel oxide for inverted structure perovskite solar cells显示文摘The emergence of inverted perovskite solar cells(PSCs) has attached great attention derived from the potential in improving stability. Charge transporting layer, especially hole transporting layer is crucial for efficient inverted PSCs. Organic materials were used as hole transporting layer previously. Recently, more and more inorganic hole transporting materials have been deployed for further improving the device stability. Nickel oxide(NiOx) as p-type metal oxide, owning high charge mobility and intrinsic stability,has been widely adopted in inverted PSCs. High performance over 20% efficiency has been achieved on NiOx base inverted PSCs. Herein, we have summarized recent progresses and strategies on the NiOx based PSCs, including the synthesis or deposition methods of NiOx, doping and surface modification of NiOx for efficient and stable PSCs. Finally, we will discuss current challenges of utilizing NiOx HTLs in PSCs and attempt to give probable solutions to make further development in efficient as well as stable NiOx based PSCs. | Fei Ma Yang Zhao Jinhua Li Xingwang Zhang Haoshuang Gu Jingbi You | 2021 | Journal of Energy Chemistry2021，30，1： | 3 |
| 4 | Structure and Piezoelectric Properties of Lead-Free Na_(0.5)Bi_(0.5)TiO_3 Nanofibers Synthesized by Electrospinning显示文摘Lead-free Na_(0.5)Bi_(0.5)TiO_3(NBT) nanofibers with the perovskite structure were prepared by the electrospinning method.The nanofibers were about 200-300 nm in diameter and up to several hundred microns in length.The crystal structures and morphologies of the nanofibers were characterized by X-ray diffraction(XRD),Raman spectroscopy,scanning electron microscopy(SEM),and transmission electron microscopy(TEM).The effective piezoelectric property of individual NBT nanofiber was examined by piezoresponse force microscopy(PFM).The NBT nanofibers crystallized in pure perovskite phase after annealing above 700℃in air and comprised a great number of fine particles with size of 60-80 nm.In addition,the electromechanical energy conversion models for NBT nanofibers were built and demonstrated high voltage output as high as several millivolts.Such a result qualifies NBT nanofibers as a promising candidate for leadfree electromechanical conversion devices. | Di Zhou Youhua Zhou Yu Tian Yafang Tu Guang Zheng Haoshuang Gu | 2015 | Journal of Materials Science & Technology2015，31，12： | 2 |
