Application of microwave for drying of ashwagandha roots was investigated. A laboratory convective microwave dryer was already developed which had the provision of regulating of air temperature, air velocity and microwave power. Ashwagandha roots of uniform size were used in the drying experiment which were carried out at air temperatures of 40, 50 and 60°C, air velocities of 1.0 and 1.5 m/s an...

Many minerals are effective absorbers of microwave energy, whereas in general gangue materials are not. This suggests applying microwave heating to mineral processing to effect selective heating of minerai phases. Many mineral processing applications have been tested only on a laboratory scale; the engineering realities of large-scale operations have largely been overlooked. Of particular conce...

A series of five known asymmetric organocatalytic reactions was re-evaluated at elevated temperatures applying both microwave dielectric heating and conventional thermal heating in order to probe the existence of specific or nonthermal microwave effects. All transformations were conducted in a dedicated reactor setup that allowed accurate internal reaction temperature measurements using fiber-o...

This article presents the application of microwave-induced pyrolysis to total recovery of resources and energy from rice straw. The microwave power and particle size of feedstock were both key parameters affecting the performance of microwave-induced pyrolysis. Under 400-500W microwave power, the reduction of fixed carbon in the biomass was significant. From the experimental results of specific...

This study is aimed to the comparison of the sensitivity of linear spectral asymmetry index (SASI) and nonlinear Higuchi’s fractal dimension (HFD) methods for detecting modulated microwave effect on human electroencephalographic (EEG) signal at non-thermal level of exposure. The experiments were carried out on a group of 14 healthy volunteers exposed to 450 MHz microwave radiation modulated at ...

Switchgrass is a promising lignocellulosic biomass for fuel-ethanol production. However, pretreatment of lignocellulosic materials is necessary to improve its susceptibility to enzymatic hydrolysis. The objectives of this study were to examine the feasibility of microwave pretreatment to enhance enzymatic hydrolysis of switchgrass and to determine the optimal pretreatment conditions. Switchgras...

In this research, experiments were performed to study thermoregulation in the canine prostate during microwave hyperthermia. The transurethral thermal therapy (T3) system provided by Urologix, Inc. was used to impose microwave heating in the canine prostate. Five types of temperature responses to different microwave power levels as time varies, including both damped and sustained oscillatory te...

We report on the development and utilization of a double split-ring microwave resonator for uniform and efficient coupling of microwave magnetic field into nitrogen-vacancy (NV) centers in a diamond over a mm(2) area. Uniformity and magnitude of delivered microwave field were measured using the Rabi nutation experiment on arrays of diamond nanowires with ensemble NV centers. An average Rabi nut...

Microwave-induced thermal acoustic imaging (MITAI) is a promising early breast cancer detection technique, in which image construction is based on thermo acoustics signals generated by the illumination of microwave pulses in tissue. In this work we have performed a microwave induced thermal acoustic signal generation simulation study using Comsol Multiphysics. A biological tissue model irradiat...
