Publication number: 20210162386Abstract: Catalysts and methods for use in conversion of glycerides and free fatty acids to biodiesel are described. A batch or continuous process may be used with the catalysts for transesterification of triglycerides with an alkyl alcohol to produce corresponding mono carboxylic acid esters and glycerol in high yields and purity. Similarly, alkyl and aryl carboxylic acids and free fatty acids are also converted to corresponding alkyl esters. Catalysts are capable of simultaneous esterification and transesterification under same process conditions. The described catalysts are thermostable, long lasting, and highly active.Type: ApplicationFiled: August 16, 2019Publication date: June 3, 2021Inventors: Inder Pal SINGH, Shradha SINGH, Bharat MISTRY, Zhiyong LI

Patent number: 8318954Abstract: The invention includes novel compounds, including but not limited to formula A and formula B, and an improved delivery method. These compounds and methods are useful in preventing or treating diseases or conditions associated with or caused by the presence of free radicals, and are useful for increasing cellular metabolism while simultaneously alleviating the resultant increase in oxidative stress. Specifically, a carnitine is bound to a lipoic acid derivative or to dihydrolipoic acid or its derivatives using a hydrolysable linker to form a single compound.Type: GrantFiled: February 23, 2007Date of Patent: November 27, 2012Assignee: Nou Life Sciences, Inc.Inventors: Inder Pal Singh, Shradha Singh, Antoine Noujiam, Bruce D. Hirsche, legal representative, David S. Tam
