  • Publication number: 20230320347
    Abstract: Mismanagement of infectious wastes such as test samples leads to the transmission of microbes/toxins/viruses and spread of contagious and infectious diseases. Adding a flocculating agent to liquid waste reduces the risk of spills and aerosolization. Provide is a flocculating/gelating agent comprising the sol of a selected nanomaterial with a defined weight composition in water and a poly-amino acid (polyglutamic acid), that is capable of instantaneous flocculation/gelation, thereby disinfecting both liquid as well as solid samples, rendering them non-infectious, with >99.9% microbial disinfection. Segregation, transportation and incineration of such disinfected medical wastes are easier, safer and decrease medical waste disposal costs for a healthcare facility.

  • Publication number: 20230323150
    Abstract: The control over the wettability of any surface fundamentally determines its interaction with water. In this regard, artificial surfaces with high water repellency has been of particular interest. The present invention relates to the synthesis and applications of a ceramic composite comprising phosphates of the lanthanide/rare earth series and organic phosphonic acids leading to superhydrophobic materials that offer non-wetting, multi-substrate compatible, additive compatible and antibacterial coatings with high water contact angles >150°.

  • Publication number: 20230028718
    Abstract: The present invention relates to design and applications of a class of water-soluble small molecules represented by Formula 1. In aqueous solutions the said molecules exhibit lower critical solution temperature (LCST) phase transition near room temperature, imparting a temperature triggered switching of transparency stages. Further, it discloses a solution comprising Formula 1 and a scalable smart radiative energy management system that takes form of a dynamic window, wherein the aqueous solution is sandwiched between two transparent glass panes to enable modulation of light and heat transmission. With simple and economical starting materials, the dynamic windows of present invention represent leaps towards creating a niche technology with multifarious applications in developing scalable, smart energy management systems for indoor building environments.

  • Publication number: 20220244607
    Abstract: Liquid electrolytes in electrochemical devices suffer from leakage issues and hence gel or solid electrolytes are generally preferred. The present invention intends to disclose the development of a gel electrolyte system which differs from conventional gel electrolytes via the addition of a composition controlled molecular additive, and its use in laminated electrochromic devices with improved performance.
