Microwave irradiation during tissue fixation and immunostaining reduces the sample preparation time. Microwave irradiation also facilitates the penetration of fixatives and antibody solutions into the tissues, resulting in efficient fixation and reduction of non-specific antibody binding, respectively. Experimental procedures involving immunofluorescence microscopy are time-consuming as this me...

Microwave radiation, an electromagnetic radiation, is widely use as a source of heating in organic synthesis. The basic mechanisms observed in microwave assisted synthesis are dipolar polarization and conduction. Microwave assisted organic synthesis (MAOS) has emerged as a new “lead” in organic synthesis. The technique offers simple, clean, fast, efficient, and economic for the synthesis of a l...

Microwave irradiation focused on the head of small rodents is now widely used as a means of more accurately measuring acetylcholine, choline, cyclic AMP, and several other important brain constituents. Because of its probable neurotransmitter role and rapid turnover, a similar approach was taken to study brain histamine. Histamine was measured by a modified radio-enzymatic method and was found ...

Microwave absorbing property of composites containing Ag nanoparticles filled multiwalled carbon nanotube buckypaper (Ag-BP) has been investigated. Buckypaper doped with silver was prepared by direct dispersion and filtration method. From the low temperature resistivity measurement it was found that increasing doping level decreases the electrical conductivity of the buckypaper. 30 wt. % and 40...

Background: High-frequency electromagnetic field (EMF) is generated by differentsources such as radar installations, radio and television transmitters, medical microwave diathermy device and domestic use of microwave ovens. Radiation leakage of microwave oven may be harmful for users. Kids who are residing near their mothers may expose to electromagnetic field. This study was carrie...

Highly efficient and stable MoS2 nanocrystals on graphene sheets (MoS2/GR) are synthesized via a hybrid microwave annealing process. Through only 45 second-irradiation using a household microwave oven equipped with a graphite susceptor, crystallization of MoS2 and thermal reduction of graphene oxide into graphene are achieved, indicating that our synthetic method is ultrafast and energy-economi...

An algorithm for the estimate of the soil moisture content on a global scale from dual-frequency (Cand Xbands) microwave data of the Advanced Microwave Scanning Radiometer (AMSR-E) is presented in this paper. The algorithm is based on the brightness temperature at C-band and uses the Polarization Index at X-band to correct for vegetation effects. The retrieval is obtained by inverting a simplif...

BACKGROUND In human nutrition legume seeds are usually subjected to soaking and thermal processes, mainly by using traditional cooking method. This method which has been used for decades, does not allow to control and adjust the parameters of this process. Therefore it does not seem to be the optimal method. Undoubtedly, microwave field is an alternative thermal process to conventional techniqu...

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...

Bee pollen is becoming an important product thanks to its nutritional properties, including a high content of bioactive compounds such as essential amino acids, antioxidants, and vitamins. Fresh bee pollen has a high water content (15%-30% wt %), thus it is a good substrate for microorganisms. Traditional conservation methods include drying in a hot air chamber and/or freezing. These techniques...
