Cuban barite characterization and its carbothermic reduction in microwave oven

Kinetic Study of Barite Carbothermic Reduction in Presence of Sodium Carbonate as Catalyst

Microwave oven in microbiology.

Editor, Reference to Microwave oven in microbiology laboratory, JPMA., 1992:42:2. In response to the queries by a microbiologist regarding the published paper we feel it would be appropriate to clarifr the facts. 1. Sterilization in microwaves works on a different principle than the conventional autoclave and sterilizadon is independent of temperature, just like the principle of sterilization b...

Microwave oven in microbiology laboratory.

Microwave oven can safely be used in microbiology laboratory for preparation of media. The method is convenient, reliable, economical and reproducible. It saves time and the quality of media is superior as compared to media prepared by conventional autoclaving method.

Dielectric properties and carbothermic reduction of zinc oxide and zinc ferrite by microwave heating

This paper aims to study the dielectric properties and carbothermic reduction of zinc oxide (zincite, ZnO) and zinc ferrite (franklinite, ZnFe2O4) by microwave heating. To achieve this aim, the dielectric properties were measured with an open-ended coaxial method to understand the behaviour of the samples under microwave irradiation. The effects of microwave power, duration time and sample mass...

Physics of the microwave oven

This is the first of two articles about the physics of microwave ovens. This article deals with the generation of microwaves in the oven and includes the operation of the magnetrons, waveguides and standing waves in resonant cavities. It then considers the absorption of microwaves by foods, discussing the dielectric relaxation of water, penetration depths of electromagnetic waves in matter and,...
