OBJECTIVE To compare immunohistochemical estrogen receptor expression on formalin-fixed, paraffin-embedded breast carcinoma tissue sections by using regular, extended microwave heating and pressure cooker technique for heat induced antigen retrieval. STUDY DESIGN Quasi experimental study. PLACE AND DURATION OF STUDY Department of Histopathology, Armed Forces Institute of Pathology, Rawalpin...

In this study, we have synthesized the gold nanoparticles by using Hibiscus rosa-sinensis, a medicinal plant. The gold nanoparticles were synthesized rapidly by the involvement of microwave heating. By changing of plant extract concentration, gold solution concentration, microwave heating time and power of microwave heating the optimized condition was identified. The surface Plasmon resonance f...

The purpose of the present study was to explore the influence of microwave heating for different periods on the primary and secondary oxidation, total oxidation as well as conjugation of stripped and non-stripped linseed oils. Color index of the oil samples was also evaluated to show changes of color during periodical heating. It was generally found that a significant increase in peroxide value...

Since the publication of our first paper on the microwave-accelerated metal-enhanced fluorescence (MAMEF) bioassay platform technology in 2005 (Aslan and Geddes, Anal Chem 77:8057–8067, 2005), we have been repeatedly asked to comment on the advantages of “microwave heating” with plasmonic nanostructures over conventional heating for bioassays by many of our colleagues in the community. We note ...

A new microwave heating process was developed for cooking microwaveable foods containing raw meats. A commercially available inverter-based microwave oven was modified for pasteurization of mechanically tenderized beef, inoculated with Escherichia coli O157:H7 (approximately 5 log(10) CFU/g) and packaged in a 12-oz CPET tray containing 150-mL de-ionized water. The new microwave heating system w...

In this study, snapshots of operating frequency profiles of domestic microwave ovens were collected to reveal the extent of microwave frequency variations under different operation conditions. A computer simulation model was developed based on the finite difference time domain method to analyze the influence of the shifting frequency on heating patterns of foods in a microwave oven. The results...

Microwave processing of materials has been found to deliver enormous advantages over conventional processing methods in terms of mechanical and physical properties of the materials. However, the non-uniform temperature distribution is the key problem of microwave processing, which is related to the structure of the cavity, and the placement and physical parameters of the material. In this paper...

Over a billion microwave ovens are used every day thus witnessing the importance of microwave heating in the world today. Microwave processing of polymers is a comparatively recent and vastly expanding field in industry due to economical advantages through energy saving and accelerated manufacture. Factors that hinder the use of microwaves in materials processing are decreasing every day. Epoxy...

Microwave-assisted processes have recognized advantages over more conventional heating techniques. However, the effects on the materials' microstructure are still a matter of study, due to the complexity of the interaction between microwaves and matter, especially at high temperatures. Recently developed advanced microwave instrumentation allows the study of high temperature microwave heating p...
