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.

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°.

Abstract: The invention relates to a process for the synthesis of two-dimensionally-layered-structure represented by the general Formula I with improved properties having the advantages of photonic band gap material. The structure of Formula I show enhanced and spectrally controlled/tunable photo-luminescence. Particularly, an ink formulation is created from the annealed powder of the Formula I using a polymer as a binder and organic solvent as a dispersant.

Abstract: The present invention provides white light emitting materials. The invention further provides a process for the preparation of white light emitting organogels using the concept of molecular self-assembly and partial energy transfer. The donor acceptor type molecules on coassembly and subsequent irradiation with suitable wavelength light produce white light. On irradiation, partial transfer of the excitation energy from the donor to the acceptor takes place, resulting a broad emission covering the entire range from 400-700 nm to give bright white light emission with CIE coordinates of (0.31, 0.35).

Abstract: The present invention provides pyrrole end-capped bipyridine derivative having a general formula (1) useful for the detection of zinc ions in solution. The present invention also provides a process for the preparation of pyrrole end-capped bipyridine derivative having a general formula (1). The present invention further provides a dipstick device by coating the assay powder of formula (1) in alumina over a thermoplastic or a glass solid support. The detection event can be monitored by noting the color change and the intense fluorescence change on the surface of the dipstick. For zinc ions, in addition to the color change an intense fluorescence change from greenish-yellow to red is observed. Detection event by means of fluorescence change is selective for Zn2+ ions when compared with all other biologically important metal ions like Na+, K+, Ca2+; Mg2+, Cu2+. The present dipstick is reusable, and can conduct the analysis of different samples using same stick.

Abstract: The present invention provides nanocomposite materials comprising carbon nanotubes and oligo(p-phenylenevinylene) (OPV). Dispersion of CNT in the solution of solution of oligo(p-phenylenevinylene) (OPV) in organic solvent results in the formation of nanocomposite material. The ?-? interaction between CNT and OPV molecule were shown by spectroscopic and microscopic techniques. The nanocomposite solution can be drop casted over glass or metallic surface for the preparation of superhydrophobic coating. The resultant composite surface shows superhydrophobic nature even with corrosive liquids and its contact angle is almost constant even after prolonged contact with water.
