Effect of Silver Doping on the Microstructure and Photocatalytic Performance of Ag-TiO2 Coatings on Unglazed Ceramic Open
TiO2 coating photocatalytic activity is limited to short-wavelength ultraviolet (UV) irradiation. To extend its potential to the visible range, doping with semiconductors such as silver (Ag) has been proposed. The optimal amount of Ag inco…

Variation of EFB-bicomponent fiber composition and its effect towards thermal resistivity and acoustical absorption as an air-conditioner ductwork inner insulation Open
Duct liner is utilized as a thermal insulation to avoid thermal loss from the cooled-conditioned airstream and as a sound insulation in air-conditioning systems. Usually, fiberglass is used as duct liners. However, its hazardous splints ar…

Comparison on the TiO2 crystalline phases deposited via dip and spin coating using green sol–gel route Open
TiO2 exist in three polymorphs known as anatase, rutile and brookite. Amongst these polymorphs, brookite are less reported and mostly produced as a by-product. In this work, two deposition methods which are dip and spin coating are selecte…
