The effect of microwave (MW) treatment to improve the adhesion of carbon nanotubes (CNTs) to a Ni/Ti/Au/SiO2/Si substrate was examined. CNTs were synthesized at a low temperature (400 C) by thermal chemical vapor deposition to avoid metal peeling. Results demonstrated that nearly 100% of MW-treated CNTs remained on the substrates even after sonication in a buffer solution. This was a significan...

BACKGROUND The degree of polymerization of amylose starch in potato was so large that the gel was hardness after gelatinization. Therefore, it is one of the most important ways that the microwave treatment was used to change the physicochemical properties of starch gel to make it suitable for the preparation of instant food. RESULTS The effect of microwave treatment on the physicochemical pro...

The aims of this study were to introduce a new laboratory microwave device developed for the modification of wood properties and to examine the effect of microwave radiation on moisture loss, surface temperature, and mechanical properties (the static modulus of elasticity MOE, and the modulus of rupture MOR) of Norway spruce (Picea abies). The device was developed for a continuous modification ...

Extraction yields and fatty acid profiles from freeze-dried Chlorella vulgaris by microwave pretreatment followed by supercritical carbon dioxide (MW-SCCO(2)) extraction were compared with those obtained by supercritical carbon dioxide extraction alone (SCCO(2)). Work performed with pressure range of 20-28 Mpa and temperature interval of 40-70 °C, gave the highest extraction yield (w/w dry weig...

background: there are many varieties of compounds in chemical and petrochemical wastewater. one of the important members of the chlorophenols (cps) family is ρ-chlorophenol. this pollutant is introduced into the environment through various human activities such as waste incineration, uncontrolled use of wood preservatives, pesticides, fungicides and herbicides, as well as via bleaching the pulp...

Gamma-aminobutyric acid (GABA) metabolism was studied in rats chronically exposed to 2.86 GHz microwaves at an incident power level of 10 mW/cm or acutely exposed to incident power levels of 40 or 80 mW/cm. No changes occurred in whole brain GABA levels or L-glutamic decarboxylase activity following these exposures. These results suggest that an altered GABA metabolism is not involved in report...

The microwave power transmission is an approach for wireless power transmission. As an important component of a microwave wireless power transmission systems, microwave rectennas are widely studied. A rectenna based on a microstrip dipole antenna and a microwave rectifier with high conversion efficiency were designed at 2.45 GHz. The dipole antenna achieved a gain of 5.2 dBi, a return loss grea...

Introduction: Recent increase of endocrine disorders may be correlated to the increased exposure to electromagnetic fields from various instruments. Radiation leakage from microwave oven may be harmful for users. Ladies have the highest levels of contact with microwave ovens. This study was carried out to evaluate the effect of radiation leakage from microwave oven on body weight, cortisol a...

listeria monocytogenes can be found throughout the environment and in many foods. it is associated primarily with meat and animal products. listeria monocytogenes has become increasingly important as a food-borne pathogen. the aim of this study was to evaluate the effect of microwave (mw) treatment of chicken meat samples which were inoculated with l. monocytogenes. drumettes of broiler carcass...
