the conventional optical disk structure using single femtosecond laser pulse irradiation were investigated, and the related parameter window was provided. 2 Experimental The disks were prepared... storage inside transparent materials[J]. Opt Lett, 1996, 21: 2023-2025. [2] WATANABE M, SUN H B, JUODKAZIS S, TAKAHASHI T, MATSUO S, SUZUKI Y, NISHII J, MISAWA H. Three- dimensional optical data storage......
at the new campus of Tianjin Polytechnic University (TPU). A couple of deep geothermal wells which are 2 300 m in depth were dug. Deep geothermal energy cascade utilization is achieved by two stages of plate... sunshine winter day is presented. The design idea of this system can be referred in other multi-energy building system designs. 2 Systems and operation strategy The geothermal, solar thermal and natural gas......
resistant are reviewed. 2 Arsenic resistance mechanisms In biological systems, arsenic typically exists in two oxidation states, arsenite (As Ⅲ) and arsenate (As Ⅴ). Arsenic resistance mechanisms have been... in Leptospirillum. This is especially so in the case of L. ferrooxidans where only a single arsB was found without any sign of an arsC gene (arsenate reductase) or arsR regulator. 2) Beside chromosomal ars genes......
practice of gas atomization technique is impeded severely[9, 10]. Therefore, the investigation of metal sheet break mechanism in the close-coupled gas atomization was carried out in this paper. 2 ... due to the interference of other droplets and sheets. 2) The melt sheet breakage approach is related to its thickness: when the melt sheet is thicker than 20μm, no caves occur on the surface, showing......
of a single-atom QPC and hence the summarization of results as ‘single-atom spintronics’. 2 Experimental Fig.1 shows a microfabricated templates made of Co thin film electrodes. The spacing between the Co..., using a cobalt sulfamate solution (75 g?L-1 Co as metal in Co(SO3NH2)2?2H2O; 30 g?L-1 boric acid, pH 3.2 to 3.3). Fig.1 High-magnification SEM micrograph of a microfa-bricated template The size......
of particle distribution on the fracture behavior and helpful for improving the fracture toughness of PRMMCs. 2 Modeling and simulation In order to develop an appropriate finite element to analyze... by conducting molecular dynamics simulation. In this study, the ANSYS element type of INTER203 is chosen and the parameters are set according to the simulation by DANDEKAR and SHIN [23], as shown in Fig. 2......
