The calculated hot deformation activation energy Q is 158.144 KJ/mol. Stress exponent is 6.6. The deformation...

The effects of washing method, lime neutralization, flotation method and microwave method of different pretreatment process of Yunnan phosphorus building gypsum strength and crystal morphology. Through, a lot of experiments comparing the four kinds of pretreatment effect, the results show that: after...

Multi-walled carbon nanotubes (MWNTs) were modified by amidoxime group, characterized by fourier transform infrared spectrometer (FTIR). The adsorption experiments of Pb(Pb) on raw MWNTs and amidoxime group modified MWNTs(AO-MWNTs) were studied under different conditions. Results showed that, the adsorption...

The magnetic field intensity distribution near a circular defect of a metallic cylinder was computed using finite element analysis. It is found that there is an obvious interference to the local magnetic field intensity when the pipeline with a defect was placed inside a Helmholtz coil, which provides...

The present paper reports on the development of an autonomous, lightweight, and robust insole pressure sensor array system. The system measures plantar pressure on the go and channels the information to a mobile device but also stores it onboard, enabling post-measurement data analysis. The collected...

Indium-Tin-Oxide (ITO, tin-doped In2O3) films with low resistivity (7.7×10-5 ohm cm) and high carrier electron concentration (1.8×1021 cm-3) was successfully prepared by spray chemical vapor deposision in air and post-deposition annealing in reducing atmosphere in our previous papers; Y. Sawada et al.,...

Lead zirconate titanate (PZT) ceramic, as a kind of piezoelectric material, is widely used in the field of electronic industry because of its excellent piezoelectric characteristics and low cost. Research works found that during the working time of the PZT ceramic, an electrical degradation phenomenon...

We prepare binary phase change materials by using decanoic acid-lauric acid and use swelling vitrified beads as adsorption carrier, adoptting vacuum adsorption method to prepare composite phase change material. We measure that the phase change temperature and phase change latent heat of different proportions...
