Thermally stimulated interactions between silver and glass, that is, dissolution as Ag+ precipitation Ag0 were studied in two glass series of molar target composition xAg2O–(19 − x)Na2O–28ZnO–53B2O3 with x = 0, 0.1, 0.5, 5 (19Na2O–28ZnO–53B2O3)+yAg2O y 0.01, 0.05. These act model for low-melting borate glasses being part metallization pastes. The occurrence metallic precipitates melt-quenched i...

Melamine formaldehyde microcapsules containing paraffin wax as phase change material (PCM) were synthesized. Free space was generated in-situ inside microcapsules. These characterized by FTIR Spectrophotometer, Scanning electron microscope (SEM), Differential colorimeter (DSC), and optical microscope. It confirmed that PCM successfully encapsulated the shell material. Encapsulated showed good p...

Nanofabrication through plasma route has been used for fabrication of Nanoparticles and Nanostructured materials as it is indicated that plasma route is superior to other physical and chemical techniques. Srivastava has established, the deposition of nanoparticles through plasma route on different substrates using Dense Plasma Focus device (DPF). DPF is a source of hot (1-2 keV) and dense (10 2...

We describe the three-dimensional (3-D) image formation and data acquisition in a stage scanning 4Pi confocal fluorescence microscope with the use of two-photon excitation. The 3-D point-spread functions of the 4Pi confocal and regular confocal microscope are measured and compared. Particular emphasis is given to the data acquisition procedure. 4Pi confocal microscopy results in a point-spread ...

At the University of Karlsruhe, a flexible micromanipulation station based on high-precise piezo-driven microrobots has been developed. Providing a flexible tool in several application fields in the micro world the robots operate either on the stage of an automated light optical microscope or inside the vacuum chamber of a scanning electron microscope (SEM). In order to automate manipulating ta...
