Abstract: A method of making an antimicrobial textile comprising TiO2 nanoparticles is described. The TiO2 nanoparticles are immobilized by first treating a textile with a base, and then contacting with TiO2 nanoparticles in a solution of an alcohol and acid. The textile may be subsequently irradiated with UV light prior to use. The antimicrobial textile shows high effectiveness against the growth and proliferation of microorganisms transmitted within indoor environments.

Abstract: A solar powered smart window includes a light diffuser configured to convert an incident direct solar radiation to a diffusive light toward interior direction, a light diffuser positioner, a driving mechanism, a solar panel, and a control unit. The control unit moved the light diffuser from a predetermined opened position to a closed position and to hold the light diffuser at the closed position with latch mechanism, when the output power of the solar panel exceeds a threshold for over a duration time. The controller releases the latch mechanism and to cause the light diffuser to return to the predetermined opened position when the output power lowers below threshold for over the duration time. A method includes storing a predetermined condition, monitoring the output power, comparing the output power with the predetermined conditions, making decision whether a positional transition is necessary, and causing the transitional transition or maintaining current position.

Abstract: A composite nanomaterial of ZnO impregnated by, e.g., a green copper phthalocyanine compound (CuPc) can be an efficient solar light photocatalyst for water remediation. The composite may include hollow shell microspheres and hollow nanospheres of CuPc-ZnO. CuPc may function as a templating and/or structure modifying agent, e.g., for forming hollow microspheres and/or nanospheres of ZnO particles. The composite can photocatalyze the degradation of organic pollutants such as crystal violet (CV) and 2,4-dichlorophenoxyacetic acid as well as microbes in water under solar light irradiation. The ZnO—CuPc composite can be stable and recyclable under solar irradiation.

Abstract: A method of producing polycrystalline Y3Ba5Cu8Oy (Y-358) whereby powders of yttrium (III) oxide, a barium (II) salt, and copper (II) oxide are pelletized, calcined at 850 to 950° C. for 8 to 16 hours, ball milled under controlled conditions, pelletized again and sintered in an oxygen atmosphere at 900 to 1000° C. for up to 72 hours. The polycrystalline Y3Ba5Cu8Oy thus produced is in the form of elongated crystals having an average length of 2 to 10 ?m and an average width of 1 to 2 ?m, and embedded with spherical nanoparticles of yttrium deficient Y3Ba5Cu8Oy having an average diameter of 5 to 20 nm. The spherical nanoparticles are present as agglomerates having flower-like morphology with an average particles size of 30 to 60 nm. The ball milled polycrystalline Y3Ba5Cu8Oy prepared under controlled conditions shows significant enhancement of superconducting and flux pinning properties.
Abstract: Base material arrangements having at least two layers can accommodate the addition of antifungal material (nanofiller), such as in denture base resin without significantly compromising the mechanical properties and/or translucency of the base material arrangements. Antifungal agents such as nanosilver and nanozirconia can be used to modify a surface layer of the material arrangements, such as the denture base, to overcome certain known shortcomings of the modified materials, e.g., typical acrylic resins containing nanosilver and nanozirconia.
