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...

hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

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...

Microwave assisted extraction technique was employed to extract pectin from citron peel. Box-Behnken design was applied to investigate the influence of irradiation time, microwave power and pH on the yield and DE of pectin. The finding indicated that the optimal conditions for the maximum yield of pectin (30.71%) were achieved at irradiation time of 3 min, microwave power of 700 W and pH of 1.5...

The effects of microwave interference on the operational parameters of individual MOSFET devices on CMOS wafers were studied as microwave power and frequency were varied. The study used direct injection of microwave power into the device terminals, and the output characteristics were measured with and without the microwave interference. The study showed that injected microwave power significant...

The purpose of this research work was to investigate the optimum operating conditions for biodiesel production from castor oil using a microwave. The Box–Behnken design of experiment was carried out using the Design Expert 7. A response surface methodology (RSM) was used to analyze the influence of the process variables (molar ratio of methanol to castor oil, catalyst concentration, reaction ti...

In this paper, we present the concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. A wireless power transmission using microwave is a system which contains satellite based solar power system (SPS), microwave generator, microwave transmitter (magnetron) and microwave rece...

Since the rose water is used in food, pharmaceutical, and cosmetic products, its microbiological control is necessary. Conventional pasteurization methods cause undesirable changes in taste, smell, medicinal properties and nutritional value with decreasing the amount of essential oil, because of high temperatures. In this study, the effects of the microwave power, temperature, ultrasound power,...
