Latest Patents

One of Sudhagar Mani's latest patents involves the development of nitric oxide-releasing packaging membranes. These biodegradable composite membranes are made from nanocellulose fibrils, chitosan, and S-Nitroso-N-acetylpenicillamine (SNAP). They have been tested for food packaging applications. The nitric oxide donor, SNAP, was encapsulated in a solution of chitosan and mixed with nanocellulose fibrils to create a composite membrane. Scanning Electron Microscopy (SEM) micrographs confirmed the uniform dispersion of chitosan and SNAP within the nanocellulose fibrils. The membranes without SNAP exhibited lower water vapor permeability compared to those with SNAP. The incorporation of SNAP also resulted in a decrease in the Young's modulus for both 2-layer and 3-layer membrane configurations. The antimicrobial property evaluation of these membranes demonstrated an effective zone of inhibition against bacterial strains, showcasing their potential applications in food packaging.

Another significant patent by Sudhagar Mani focuses on the torrefaction reduction of coke formation on catalysts used in the esterification and cracking of biofuels derived from pyrolyzed lignocellulosic feedstocks. This bio-oil production process, which includes torrefaction pretreatment, catalytic esterification, pyrolysis, and secondary catalytic processing, significantly reduces the yields of reactor char, catalyst coke, and catalyst tar. The reduction in coke due to torrefaction was found to be 28.5% relative to the control for slow pyrolysis bio-oil upgrading, while in fast pyrolysis bio-oil processing, the reduction was 34.9%. Torrefaction at 275°C also reduced levels of acid products in the bio-oil, enhancing catalyst effectiveness and increasing aromatic hydrocarbon yields in the upgraded oils.
