ZnO nanotapered arrays (NTAs) with successively modulated sharpness have been successfully demonstrated by a novel supersaturation-controlled hydrothermal method in zinc-NH3·H2O system. The filament-like, needle-like, sword-like, and pagoda-like ZnO NTAs with cone angle ranging from ∼0°, 4.9 ± 1.5°, 20.4 ± 3.7° to 63.7 ± 2.5° can be obtained in an early supersaturated solution with different supersaturation...
This paper reports the designing, simulation and initial experimental investigation into a LTCC vacuum microsystem package substrate acting both as a vital panel and a functional structure for compact system-in-package (SiP) integration. Design, validation and experimental results for microchannels with different planar axial shapes are presented. Experimental and simulated temperature distribution...
The heat dissipation of six different types of microchannel networks integrated in LTCC based microsystems has been investigated by experimental measurement and simulation analysis, including straight, serpentine, spiral and fractal-shaped microchannel networks of curve, I-shaped and parallel. The cross section of microchannel is 200 ??m ?? 200 ??m and the total length is about 200 mm. The water mass...
