A transparent and colourless projection screen is fabricated by depositing a silver nanocube sub-monolayer on a titania thin film. Backward scattering of the silver nanocubes is enhanced by titania in the blue and red regions, to which human eyes are less sensitive. As a result, this screen, which is cost-effective even for large areas, allows projection of full colour images.

Fifteen commercial titania (titanium(iv) oxide; TiO(2)) powders were modified with gold by photodeposition to prepare photocatalysts that work under irradiation with light in the visible range (vis). The gold-modified titania (Au/TiO(2)) powders were characterized by diffuse reflectance spectroscopy (DRS), field-emission scanning electron microscopy (FE-SEM), scanning transmission microscopy (S...

Photocatalysts produce free radicals upon receiving light energy; thus, they possess antibacterial properties. Silver (Ag) is an antibacterial material that disrupts bacterial physiology. Our previous study reported that the high antibacterial property of silver nanoparticles on the surfaces of visible light-responsive nitrogen-doped TiO2 photocatalysts [TiO2(N)] could be further enhanced by vi...

A supported gold nanoparticle-catalyzed strategy has been utilized to promote a click chemistry reaction for the synthesis of 1,2,3-triazoles via azide-alkyne cycloaddition (AAC) reaction. While advent effective non-copper catalysts (i.e., Ru, Ag, Ir) demonstrated catalysis AAC reaction, additional robust catalytic systems complementary copper catalyzed remain in high demand. Herein, Au nanopar...

Nano sulfated titania was tested as solid acid heterogeneous catalyst for the synthesis of 4-(Trifluoromethyl) coumarin and coumarin derivatives under solvent-free condition. Factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents.  This nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. The prepared sulfated titania s...

The deployment of photocatalysis for remediation water has not yet been realized, although laboratory-scale studies have demonstrated promise. Accomplishing this requires the development as a process, including studying its efficiencies in remedying when high volumes are processed, and addressing recovery, possible regeneration reuse photocatalysts. To that end, work is aimed at demonstrating u...

The current study explores a three-dimensional swirling flow of titania–ethylene glycol-based nanofluid over stretchable cylinder with torsional motion. heat transfer process is explored subject to source/sink. Here, glycol–water-based used. Maxwell–Bruggeman models for thermal conductivity and modified Krieger–Dougherty viscosity are employed scrutinize the impact nanoparticle aggregation. A m...

We describe the use of benzyl alcohols in a solvothermal/alcoholysis reaction to form nanocrystalline sheets of anatase titania. By tuning the reaction conditions, we adjust the size of the nanosheets. The type and density of benzyl groups that decorate the basal plane of the titania sheets control the self-assembly into layered structures. These layered materials can be grown from solid substr...

Well-defined, ordered arrays of nanoscale depressions were obtained in linear-brush-type polystyrene-block-polycarbosilane (PS-b-PCS) diblock copolymer thin films by acetone vapor annealing and silica nanodot arrays were directly obtained from such thin films deposited on a titania substrate by one-step exposure to UV light as a result of transformation of the PCS units to silica, driven by the...
