Nano-porous titania matrices were doped with AgNPs by UV assisted reduction of AgNO3 solution to fabricate the photo-anode in dye sensitized solar cell using N3 as the absorber dye. The composite matrices were subjected to physicochemical characterization using XRD, TEM, XPS, EDAX, FESEM, spectral and micro Raman techniques. Electrochemical characterizations of the Ag-TiO2 matrices were carried out...
A new ruthenium photosensitizer [Ru(triOMePhtpy)(bpydca)(NCS)]PF6 (1) (triOMePhtpy=4′-(3,4,5-triOMe)Phenyl-2,2′:6′,2″-terpyridine; bpydca=4,4′-dicarboxy-2,2′-bipyridine) has been synthesized and characterized by IR, UV–Vis, NMR and Mass spectroscopy. The molecule shows a moderately intense MLCT band at 511nm. Along with the intraligand transitions in the UV region, the molecule shows several high...
Sustainability of old buildings is constantly challenged due to its non-compliance with energy saving practices. Old buildings which aim to deploy technologies to improve thermal comfort face some infrastructure constraints. The sustainability of such buildings is dependent on occupant's thermal comfort, low carbon emissions and reduced energy consumption. Such buildings face restraints in the way...
The noise transfer characteristics in an electro-absorption modulator are investigated. The transfer of intensity noise is assessed by considering the optical signal-to-noise ratio and relative intensity noise of the optical signals. An electro-absorption (EA) modulator is described from the viewpoint of noise transfer characteristics, where input optical signals are converted to electrical signals...
Indoor air quality (IAQ) is a term describing the air quality of a building; especially it refers to the health and comfort of building occupants. It refers to the nature of the conditioned air that circulates throughout space/area, where we work and live in. IAQ can be affected by microbial contaminants (mold, fungus) which largely depend on temperature and humidity condition of a room, gaseous pollutants...
