The present disclosure generally relates to an advanced ceramic catalyst made by metal oxides dispersed in refractory ceramics and the process of making same. The advanced ceramic catalyst is capable of significantly lowering carbon foot prints and noxious emissions by generating the same heat energy with much lower quantity of fuel such as of natural gas, propane and other gaseous hydrocarbons. A process of making such a catalyst from inexpensive combination of metal oxide prepared in solution to have many oxygen lattice defects and particle size distribution selected from nanometer to millimeter range which can provide a huge surface area for combustion reaction thus lowering the activation energy of combustion.

Advanced ceramic catalyst

The invention relates to a composition and process for producing a chemically stable magnetic fluid comprising a plurality of magnetic particles covered first with a small molecular weight surface modifier, which is a nondispersant and acts as a surfactant-accepting layer, and then with at least one surfactant. The surface modifier/surfactant coated magnetic particles are then suspended in a silicone oil-based, hydrocarbon oil-based or an ester oil-based carrier liquid.

Ferrofluid composition and process

The invention relates to a composition and a process for producing a chemically stable magnetic fluid comprising finely divided magnetic particles covered with surfactants. A surface modifier is also employed which is added to cover thoroughly the free oxidizable exterior surface of the outer layer of the particles to assure better chemical stability of the colloid under different environmental conditions.
