Abstract: 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.

Abstract: The present invention relates to a process for the synthesis of B-site doped ABX3 perovskite nanocrystals. The process comprises the steps of loading non-halide precursors of A, B, and dopant in three neck flasks along with long chain acid and olefin, purging of the reaction mixture under heating, and finally injection of alkylammonium chloride stock solution in the reaction mixture at a desired temperature. Introducing transition metal such as Mn and other rare earths, etc., as dopants in the perovskite nanocrystals to induce a new optical window.

Abstract: The present invention relates to an anti-viral nanoformulation suitable for diverse surface application in form of hydrogel based nanoemulsion, or an aerosol spray. The present invention discloses incorporation of nanomaterials such as functionalized carbon quantum dots (F-CQDs), copper nanoparticles (CuNPs) or silver nanoparticles (AgNPs) into the hydrogel (HG) scaffold to act as chemical barrier and anti-viral agent against SARS-CoV-2 or Escherichia coli: phage MS2. The nanoformulation is coated on personal protective equipment's (PPE) and different surfaces such as glass, steel and plastic to control viral infection including corona virus infection.
