Abstract: A method for forming a silicon carbide material with a plurality of negatively charged silicon mono-vacancy defects includes irradiating a silicon carbide sample, annealing the irradiated silicon carbide sample in an annealing operation, and quenching the annealed silicon carbide sample. Quenching may include heating the annealed silicon carbide sample to a maximum temperature and quenching the annealed silicon carbide sample to form the silicon carbide sample with the plurality of negatively charged silicon mono-vacancy defects.

Abstract: A method of freeze treating mayonnaise and mayonnaise-containing products, such as egg, chicken, or ham salad, in which the frozen product may be satisfactorily stored and upon thawing maintains the physical and chemical characteristics of its pre-frozen state, which method comprises immersing mayonnaise or a mayonnaise-containing product in an inert liquid which is maintained at a temperature of between approximately -50.degree.F. and 0.degree.F., maintaining the product therein until completely frozen and removing the product and storing it at temperatures of between approximately -50.degree.F. and 0.degree.F.

Abstract: A method of freeze treating a cooked egg product which does not result in substantial changes in the physical or chemical characteristics of the later thawed product, which method comprises immersing and retaining the cooked egg product in a bath of a liquid freezing medium for a relatively short predetermined period while the freezing medium is held at a temperature within the range of approximately 0.degree.F to approximately -325.degree.F.
