Sol–gel synthesis of defect-pyrochlore structured CsTaWO6 and the tribochemical influences on photocatalytic activity

RSC Advances, 2013
The semiconductor mixed oxide photocatalyst CsTaWO6 was prepared via an aqueous sol–gel citrate route for the first time. The mild reaction conditions yield smaller primary particle sizes and larger specific surface areas than the conventional solid state reaction. The photocatalytic properties are determined using both photocatalytic terephthalic acid

Controllable transport mean free path of light in xerogel matrixes embedded with polystyrene spheres [PDF]

, 2008
Xerogel matrices, made by sol-gel techniques, are embedded with polystyrene spheres to promote multiple scattering of light. Varying the concentration of the spheres inside the matrix allows one to adjust the transport mean free path of light inside the ...

Individual sol-gel microencapsulation of benzoyl peroxide and tretinoin enables controlled release onto the skin

Heliyon
A combination of benzoyl peroxide (BPO) and tretinoin is recommended for treating acne; however, concurrent administration can be irritating, and coformulation is prevented by BPO-mediated oxidation of tretinoin.
