摘要： The present invention relates to a new method for creating nanopores in single layer molybdenum disulfide (MoS2) nanosheets (NSs) by the electrospray deposition (ESD) of silver ions on a water suspension of the former. Electrospray deposited silver ions react with the MoS2 NSs at the liquid-air interface resulting in Ag2S nanoparticles (NPs) which goes into the solution leaving the NSs with holes of 3-5 nm diameter. Specific reaction with the S of MoS2 NSs leads to Mo-rich edges. Such Mo-rich defects are highly efficient for the generation of active oxygen species such as H2O2, under visible light, which causes efficient disinfection of water. The holey MoS2 NSs shows 105 times higher efficiency in disinfection compared to normal MoS2 NSs. Developed a conceptual prototype and tested with multiple bacterial strains and a viral strain, demonstrating the utility of the method for practical applications.

摘要： The present invention relates to adurable and multifunctional superhydrophobic coating composition and water based fabrication method of producing the durable and multifunctional superhydrophobic coating composition via chemical modification and functionalization of hydrophilic material by silanes under room temperature without any organic solvents. Synthesis of chemically modified cellulose nanofibers or clay in water forms excellent water repelling thin films upon coating over various substrates. The super hydrophobic materials are used as additive for paints, pigments, paper, varnish and, textile and used for various industrial applications such as construction of buildings and other super structures.

摘要： The present invention relates to a method of enhancing heat transfer of metallic surfaces by (1) fabricating hierarchical micro-nanostructured surfaces using etching processes, and (2) fabricating hydrophobic and hydrophilic regions, using a printing or a coating technique, followed by etching. The said method enhances the density of condensation sites over a metallic surface and additionally facilitates the departure of condensed droplets from the surface. Such a surface also enhances the sensible heat transfer characteristics, and improves the coefficient of performance (COP) of refrigeration systems for applications like atmospheric water generators, dehumidifiers, air conditioners, etc.

摘要： Coated mesoflower are described including: a metallic mesoflower core having a first surface and including at least one protrusion terminating in a tip; a non-metallic coating covering and substantially conformal to the first surface, thereby creating an outer surface of the coated mesoflower; and a marker material having an optical property that is enhanced in the presence of the coated mesoflower. Coated hollow mesoflowers that do not have the metallic mesoflower core are also described.

摘要： A luminescent nanocomposite comprising functionalized graphene and a luminescent moiety, its fabrication, and uses are described. The luminescent moiety is anchored non-covalently to the functionalized graphene. Luminescence properties of the nanocomposite may be modulated by choosing appropriate luminescent moieties such as native lactoferrin, native lactoferrin protected gold clusters, and so forth. Mechanical properties of the nanocomposite may be modulated by adding a biopolymer such as Chitosan. The nanocomposite may be used as a luminescent ink for encoding information, or a luminescent film for tagging articles of manufacture such as electronic waste components.
