The aim of this study was to investigate the therapeutic efficacy of percutaneous radiofrequency (RF) ablation versus microwave (MW) ablation for hepatocellular carcinoma (HCC) measuring ≤ 5 cm in greatest diameter. From January 2006 to December 2006, 78 patients had undergone RF ablation whereas 77 had undergone MW ablation. Complete ablation (CA), local tumour progression (LTP) and distant re...

A fast, general, environmentally friendly and facile method for preparation of five- and six-membered ring diazaheterocylic salts under microwave irradiation is presented. The N-alkylation reactions of imidazole, pyrimidine, pyridazine and phthalazine have been studied. The microwaves remarkably accelerated these N-alkylations, the reaction times decreased dramatically, the reaction conditions ...

This study was conducted to investigate firstly, the oxidative stress and erythrocyte hemolysis induced by exposure to 2450 MHz continuous wave microwave (MW), which is the carrier of signals emitted by cellular phones. Secondly to evaluate the possible protective role of grape seed extract. Male rats were randomly divided into four groups, the first group was considered as control, the second ...

Microwave-assisted dilute acid/alkali pretreatment is an efficient and rapid method of removing lignin and hemicellulose, however, the optimized parameters for the maximum efficiency have to date not been presented in the literature. The purpose of this study was to determine those conditions by examining the effects of three factors: microwave power, temperature, and time on delignification in...

The current study is aimed to utilize the microwave for isolation of colorant from neem bark and its application onto chemical & bio-mordanted cotton fabric. For the purpose, aqueous, acid and organic media have been employed to isolate the colorant and to make its application onto surface modified and bio-mordanted cotton fabric followed by microwave treatment up to 6min....

The microwave-induced acceleration of photocatalytic reactions was discovered serendipitously in the late 1990s. The activity of photocatalysts is enhanced significantly by both microwave radiation and UV light. Particularly relevant, other than as a heat source, was the enigmatic phenomenon of the non-thermal effect(s) of the microwave radiation that facilitated photocatalyzed reactions, as ev...

The microwave (MW) field can be measured by the Autler–Townes (AT) splitting of electromagnetically induced transparency (EIT) spectrum in Rydberg atomic system; however, EIT-AT method fails weak MW fields. We used amplitude modulation to resolve interval directly obtained, and minimum detectable strength is improved six times compared with traditional method. proposed more intuitive convenient...

A microwave (MW) preheating mechanism of anisotropic conductive adhesive film (ACF) has been introduced in order to reduce the bonding temperature for flip chip technology. Thermal curing of epoxy shows a very sluggish and non-uniform curing kinetics at the beginning of the curing reaction, but the rate increases with time and hence requires higher temperature. On the other hand MW radiation ha...

Use of wireless communicating devices is increasing at an exponential rate in present time and is raising serious concerns about possible adverse effects of microwave (MW) radiation emitted from these devices on human health. The present study aimed to evaluate the effects of 900 MHz MW radiation exposure on cognitive function and oxidative stress in blood of Fischer rats. Animals were divided ...

Abstract This paper presents the synthesis of metal-organic structure terbium Tb 2 (BDC) 3 (BDC: 1,4-benzendicarboxylic acid) obtained by stirring at room temperature (SRT) and means microwave-assisted method (MW) 150 °C during 15 min. A comparison was made between physicochemical properties MOF each methods as they were characterized powder X-ray diffraction (XRD) Fourier transform infrared sp...
