Abstract The application of diamond material significantly improves the heat dissipation capability liquid cooling microchannels, solving bottleneck problem for highly integrated electronic components and thus promoting development a new generation military equipment. In this study, microchannels with ultra-high flux density were reliably vacuum-brazed by using AgCuTi filler metal in high vacuu...

objective: the main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. methods: drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [hg], infrared radiation at power levels of 100, 150 and 200 w in the three repetition. resu...

A torsion pendulum is described which has a lowinstrumental decrement(6 <4 x 10-5). The temperature ofthe specimen can be varied between 80 and 1150 K in twostages. Tensile or torsion deformation of the specimen invacuum can be exerted in situ. An upright torsion pendulum has been constructed for a widerange of applications. This has been achieved by a combinationof ...

We report an experimental observation of a record-breaking ultrahigh rotation frequency about 6 GHz in optically levitated nanoparticle system. trap the gravity direction with high numerical aperture (NA) objective lens, which shows significant advantages compensating influences scattering force and photophoretic on trap, especially at intermediate pressure (about 100 Pa). This allows us to fro...
