Removing water from porous Vycor glass resolves the near-IR (NIR) spectrum revealing that the emissivity of nanoporous silicas derives from two energetically distinct silanol, SiOH(H2O)x, and siloxane, SiOSi(H2O)y, surface sites. The occurrence of is

Tungsten oxides, including WO3 and mixed valent oxides, are formed in unpolished porous Vycor glass (PVG) by ultraviolet photolytic decomposition of adsorbed tungsten hexacarbonyl. The relative amounts of the oxides formed are determined by a competi

Photoinduced reduction of CO2 by H2O occurs in nanoporous Vycor glass doped with tungsten oxides derived from 312 nm photolysis of physisorbed W(CO)6. In polished forms of Vycor, a hydrated precursor to monoclinic WO3 is formed, whereas in the unpoli

The addition of Pt or Ir nanoparticles (np’s) capped with poly(vinylpyrrolidone), designated M(PVP)n, to aqueous–ethanol solutions of (bpy)2Ruppz2+, bis(2,2′-bipyridine)(4,7-phenanthrolino-5:6,5′6′-pyrazine)ruthenium(II), and (bpy)2Rudpp2+,

Photolysis of Fe(CO)5 physisorbed into porous Vycor glass creates CO pressure gradients within the nanoporous matrix that promote Fe(CO)5 diffusion within the matrix and change the distribution of the complex within the matrix. Occurring on a time sc

The proton dependencies of the absorption and emission spectra of bis(2,2'-bipyridyl)(2,3-bis(2-pyridyl)pyrazine)ruthenium(II), (bpy)(2)Ru(dpp)(2+) indicate that population of the dpp-localized MLCT state increases the basicity of dpp peripheral nitr

Photopatterning metal and/or metal oxides in porous, silica-based glasses and xerogels followed by thermal consolidation to a nonporous glass yields refractive index gradients that,depending on their shape, guide, focus, and defract light. The optica

The growth of elemental iron and iron oxide particles derived from the photolysis of Fe(CO) 5 adsorbed onto porous Vycor glass has been characterized and correlated with the optical and magnetic properties of the particles. Photolysis does not result
