Philippe Morelle Inventions, Patents and Patent

Philippe Morelle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

Fluorine enrichment of vegetables and soil around an

Chemical industry

Chemical industry - Chemical industry - Fluorine: The fluorine industry is intimately related to the production of aluminum. Alumina (aluminum oxide, Al2O3) can be reduced to metallic aluminum by electrolysis when fused with a flux consisting of sodium fluoroaluminate (Na3AlF6), usually called cryolite. After starting the process

The Simons process is widely used in the production of fluorinated organic molecules. It is believed to proceed through the electrochemical fluorination of a Ni anode using hydrogen fluoride (HF), forming an amorphous nickel fluoride film of unknown chemical

Low

Consequently, a low electrolytic voltage (1.43 V to achieve 10 mA cm –2) for H 2 production was obtained by integrating the efficiently anodic behaviors of OER and ethanol oxidation. The results reported herein point to fluorine moderation as a promising pathway for developing optimal electrocatalysts and contribute to ongoing efforts of mimicking water splitting.

US Patent Application for Process for the production of

Elemental fluorine and carbonyl fluoride are suitable etchants for producing microelectromechanical devices ("MEMS"). They are preferably applied as mixtures with nitrogen and argon. If applied in Bosch-type process, C4F6 is a highly suitable passivating gas.

Aluminum processing

Aluminum processing - Aluminum processing - Smelting: Although there are several methods of producing aluminum, only one is used commercially. The Deville process, which involves direct reaction of metallic sodium with aluminum chloride, was the basis of aluminum production in the late 19th century, but it has been abandoned in favour of the more economical electrolytic process. A
