Biosynthesis of Copper Oxide and Silver Nanoparticles by Bacillus Spores and Evaluation of the Feasibility of Their Use in Antimicrobial Paints.

Modification of paint with nanoparticles (NPs) provides self-cleaning, water/dirt-repellent, and other properties. Therefore, the aim of the present study was to biosynthesize silver (Ag) and copper oxide (CuO) NPs and to prepare NP-modified paint. To this end, AgNPs and CuONPs were biosynthesized using spores and commercial and crude dipicolinic acid (DPA) extracted from the spore of this bacterium.

Synthesis and characterization of Ag-ion-exchanged zeolite/TiO nanocomposites for antibacterial applications and photocatalytic degradation of antibiotics.

This paper investigates the synthesis, antibacterial, and photocatalytic properties of silver ion-exchanged natural zeolite/TiO photocatalyst nanocomposite. Zeolite is known to have a porous surface structure, making it an ideal substrate and framework in different nanocomposites. Moreover, natural zeolite has a superior thermal and chemical stability, with hardly any reactivity with chemicals.

Facile Synthesis of Ag Nanowire/TiO and Ag Nanowire/TiO/GO Nanocomposites for Photocatalytic Degradation of Rhodamine B.

This paper investigates the photocatalytic characteristics of Ag nanowire (AgNW)/TiO and AgNW/TiO/graphene oxide (GO) nanocomposites. Samples were synthesized by the direct coating of TiO particles on the surface of silver nanowires. As-prepared AgNW/TiO and AgNW/TiO/GO nanocomposites were characterized by electron microscopy, X-ray diffraction, UV/visible absorption spectroscopy, and infrared spectroscopy.

Towards Multi-Functional SiO@YAG:Ce Core-Shell Optical Nanoparticles for Solid State Lighting Applications.

This paper aims to investigate the synthesis, structure, and optical properties of SiO@YAG:Ce core-shell optical nanoparticles for solid state lighting applications. YAG:Ce phosphor is a key part in white light emitting diodes (LEDs), with its main functionality being the generation of yellow light. Generated yellow light from phosphor will be combined with blue light, emitted from chip, resulting in the generation of white light.

Study on the Degradation of Optical Silicone Exposed to Harsh Environments.

Degradation mechanisms of silicone plates under harsh environment conditions are studied in this investigation. Environmental degradation of silicone free form, used as secondary optics in Light Emitting Diode LED lighting lamps and luminaires or any other applications requiring high quality optics being used, has negative implications for the optical performance. Degradation of silicone plates in harsh environment conditions was studied in salt bath and swimming water environments, using different light radiation and temperatures.
