这种活性金属碳化物碳还可进一步转化为惰性的丝状碳和石墨碳.TEM和XRD分析结果表明,催化剂上生成丝状碳数量顺序为:16%Co/γ-Al2O3>>9%Co/γ-Al2O3~9%Co-Ca/γ-Al2O3(m(Ca):m(Al)=1:1).这与相应催化剂上Co微晶晶粒尺寸大小顺序(30nm>15nm>9nm)有一定的对应关系.作者认为,通过提高金属Co微晶在...

nm, is achieved with a mechanical probe miniaturized to fit inside a transmission electron microscope (TEM). The TEM tribological probe can be used for nanofriction and nanofatigue testing, with 3D control of the loading direction and simultaneous TEM imaging of the nano-objects. It is ...
hardeningdisorder-ordertransformationTEM study was made to explore the mechanism of the strain-age hardening of initially-dis-ordered (Co78Fe22)3V,which was found to be attributed to the formation of a special disloca-tion-stacking fault configuration in company with disorder-order transformation-...
High resolution (HR) TEM imaging is used to show the presence of at least 6-fold twinning on a rather fine (similar to 5 nm) scale. The (3+1)-d superspace group symmetry is suggested to be Pmmm(0, 1/2, gamma) or one of the non-centrosymmetric sub-groups thereof, namely P2mm(...
Using oxygen, water-vapor and hydrogen concentration cells and Ba_3Ca_(1.12)Nb_(1.82)O_(9-未)< /sub> (BCN18) as a solid state electrolyte the Nernstian voltages were measured at elevated temperatures. Proton transport numbers near unity were observed for pO2<10-5 bar. In the domain of...
In this paper, we describe a case study aimed at comparing two formal agent modelling languages, namely Concurrent MetateM and DESIRE. A version of the well known PRS architecture is developed and the approaches are compared with respect to this application.Marco Mulder, Jan Treur...
