Effect of low-level radiation on the low temperature acoustic behavior of a-SiO2.
نویسندگان
چکیده
We report on the mechanical behavior of an a-SiO2 84 kHz torsional oscillator operated between 100> or =T> or =1.0 mK. Below 10 mK we observed well-differentiated transient responses which we attribute to the interaction with low-level background radiation (gamma quanta and cosmic ray micro) and which can be modeled in terms of a change in the spring constant.

The Effect of Polarized Laser Radiation on Viscoelastic Properties of Soft Tissue
Background: Laser-tissue interaction on low-level laser therapy (LLLT) has widespread medical applications (e.g., improved wound healing). The tensile strength of radiated tissue by LLLT is known to be increased mainly because of cross collagen bands developed after radiation.Objective: In this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic ti...
متن کاملCatalytic and Non-catalytic Conversion of Methane to C2 Hydrocarbons in a Low Temperature Plasma
The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...
