Publication number: 20240240023Abstract: The present invention relates a biodegradable 3D composite hydrogel scaffold and a process for preparing the same from a cross-linkable synthetic biodegradable polymer, methacrylated poly multi-carboxylic acid-polyethylene glycol (MA-PMCA-PEG) and a modified natural polymer maleated gelatin (GEL-MEA). The invention deals with development of cross-linkable synthetic and natural polymers through simple and cost-effective methods. A multicarboxylic acid-b-polyethylene glycol (PMCA-PEG), is synthesized by a direct melt polycondensation technique and thereafter methacrylated using glycidyl methacrylate to prepare cross-linkable MA-PMCA-PEG, which is a new biodegradable material with excellent cross-linking properties. The natural polymer gelatin (GEL) is reacted with maleic anhydride (MEA) to get cross-linkable GEL-MEA.Type: ApplicationFiled: November 30, 2023Publication date: July 18, 2024Inventors: Mani GAJENDRAN, Jyotiranjan OTA, Samik Kumar HAIT, Sankara Sri Venkata RAMAKUMAR

Patent number: 11603503Abstract: This invention is related to an additive composition comprising metal-based quantum clusters (QCs) dispersed in a hydrocarbon medium. The additive composition is useful as a fuel additive, as it acts as a combustion improver for liquid and gaseous fuels. The invention describes a process for the synthesis of the additive composition comprising metal-based materials in atomic cluster form in hydrocarbon dispersible medium. The stable liquid dispersion of the QC has been doped into the hydrocarbon fuels at required concentrations. The measurable flame temperature of the fuels, e.g., commercial LPG on burner has been observed to increase by at least 60-80° C. The flame with high heat through put can be used for efficient cooking, heating, annealing and other high thermal applications. The additive composition may also be used to improve the fuel economy of the liquid hydrocarbon fuels.Type: GrantFiled: May 19, 2022Date of Patent: March 14, 2023Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Koushik Bhowmik, Mukesh Kumar Vyas, Jyoti Ota, Samik Kumar Hait, Vivekanand Kagdiyal, Deepak Saxena, Sankara Sri Venkata Ramakumar
