An Fe-Cr single crystal film with Cr concentration gradient (0% - 13%Cr) was prepared by electron beam deposition and irradiated by 2.4MeV Cu2+ ions at 475°C. Irradiation effects on magnetization process were investigated using a Kerr microscope. Spike domains were observed at the boundary between irradiated and unirr…
This grant provides funding for the development of a scalable nanomanufacturing platform to fabricate cyclic peptide-based nanorobots for biomedical applications, such as in vivo sensing, disease diagnosis, and targeted drug delivery. The nanomanufacturing platform will be used to assemble various types of cyclic pept…
在800℃以下,利用等电位空心阴极辉光放电特性,以针状钨钼合金棒和高纯石墨棒为源极,在Ti6Al4V合金表面进行W-Mo-C多元共渗。由于处理温度明显低于钛合金相变温度,不发生相变,避免了高温对钛合金基体的影响。利用扫描电子显微镜(SEM)观察了改性层的表面形貌和截面形貌;用XRD分析了改性层的相结构;用显微硬度计测量了显微硬度;利用球-盘摩擦磨损实验仪测试了改性层在室温干滑动摩擦条件下的耐磨性。结果表明:在温度750℃,工作气压35~50 Pa,共渗时间4 h工艺条件下,Ti6Al4V合金表面形成25μm厚的合金改性层。改性层显微硬度值达到840 HV,较基体的450 HV显著提高。改性层主要由MoTi、TixW1-x、W2C、…
Indium interlayers with thickness of 0,0.1,0.5,1 nm were deposited respectively before wurtzite InN was grown on silicon substrate by plasma-assisted molecular beam epitaxy(PAMBE).X-ray diffraction(XRD) spectra,scanning electron microscope(SEM),absorption and photoluminescence(PL) spectra were adopted to analyze the i…
Optical Constants are the fundamental thermophysical properties of materials, and spectroscopic ellipsometry (SE) has been widely applied to measure the optical constants of solids. During the ellipsometric measurements, the surface micro-roughness is one key issue, which will induce some derivation of the optical con…

For solar cell applications SWNTs have superiorities in terms of the wide spectrum of absorption ranging from near-infrared to visible wavelength, high electrical conductivity at high transparency as well as the possibility multiple exciton generation. Combined with earth abundance and chemical stability, the SWNT is…
In this paper several methods to characterisation of the impregnation have been used. Scanning electron microscopy (SEM) observations characterize qualitatively the impregnation of yarn by the presence the cement particulars in the space inter yarn. Porosimetry test: characterization of the impregnation of embedded ya…
В статье обсуждаются методические особенности исследования фазовых диаграмм давлениеконцентрациятемпература водородпоглощающих материалов, используемых в металлогидридных системах хранения и очистки водорода на основе интерметаллических соединений типа АВ5. Исследована фазовая PCT-диаграмма сплава LaFe0.1Mn0.3Ni4.8,…
A coaxial Blumlein line with a spiral inner and a spiral outer cylinders is proposed in this paper. The pulse forming process for this line is analyzed via the transmission theory of transverse electromagnetic wave. It is found that the electromagnetic wave can transmit independently in the inner line and in the outer…
Синтезированы комплексы меди(II) и никеля(II) на основе бис-азометина продукта конденсации 1-фенил-3-метил-4-формил-5-меркаптопиразола с 1,3-диаминопропанолом-2. Показано, что бис-азометин способен образовывать как биядерные, так и моноядерные комплексы, в которых гидроксильная группа не участвует в координации. В б…
本文通过首先对三效催化剂进行了简述；然后对三效催化剂的活性成分分成2大类进行简述；对非贵金属的催化剂之举钙钛矿型催化剂进行简述。最后对贵金属催化剂与钙钛矿型催化剂进行了比较。 In this paper, the three-way catalyst and its two broad headings have been introduced. Then perovskite catalyst has been recommended. Finally, the precious metal catalyst and perovskite catalyst were compared.
We have been developing a supporting program named GISP for the molecular dynamics (MD) simulation program, Gromacs. The program is designed for the researchers who are not experts of molecular modeling and for the students who want to start to learn MD simulation. We added some new features to the old version of GISP…
