Spectral Analysis of Acousto-Ultrasonic Waves for Defect Sizing
(1996)
A study of the feasibility of employing acousto-ultrasonic (AU) testing to size defects has been carried out using a model system consisting of a single defect in a glass matrix. A through-transmission mode was used for ...
Electron Transportand Recombination in Dye Sensitized Solar Cells Fabricated from Obliquely Sputter Deposited and Thermally Annealed
(2007)
This study investigated the effectiveness of three physical-chemical methods namely; pH adjustment, precipitation with alum and the use of polyelectrolytes. In the treatment of diary wastewater from Brookeside milk processing ...
Electrochemical characterization of TiO2 blocking layers prepared by reactive DC magnetron sputtering
(Elsevier, 2009)
Thin TiO 2 (anatase) films were prepared by reactive DC magnetron sputtering and characterized in detail.
Specifically, they were tested as comp act blockin g underlayers in dye-sensitized solar cells. Elastic recoil
detection ...
Stability of anthocyanin sensitized ti02 photoelectrochemical (pec) solar cells prepared by sol gel process
(2002)
Highly porous dye sensitized Ti02 thin film solar cells have been prepared hy the sol
gel process. Sensitization was achieved by use of anthocyanin pigment extracted from delphinidin
purple and cyanidin 3-5 diglucose ...
Effect of crystalline phases on the strength of (quartz-feldspar-kaolin ) porcelain
(2000)
The effect of mullite and quartz phases on the strength of Kenyan tri-axial porcelain
in the system Quartz-feldspar-kaolin has been investigated. It was found that both the
compressive and tensile strengths of porcelain ...
Effect of silica additions on strength and elastic modulus of Kenyan industrial clay ceramics
(2000)
The effect of silica additions on material properties of Kenyan industrial clay ceramics composed of 0-
50% wt silica and a feldspar-kaolin content ratio in the range 1:1 to 5:8 was investigated. Highest sintered
density ...
The Effect of Quartz and Mullite Phases on Strength of Triaxial Porcelain
(2004)
The Effect of quartz and mullite crystalline phases on the strength of triaxial porcelain in the
system quartz-feldspar-kaolin composed of20% wt silica and feldspar/kaolin ratio of 5:8 have been
investigated. It was found ...
EFFECT OF NITRATION ON PRESSED TIO2 PHOTOELECTRODES FOR DYE-SENSITIZED SOLAR CELLS
(2007)
TiO2 films made by the pressing method and then nitrogen-doped by heat-treatment in
nitrogen, oxygen and argon gas mixture have been studied and the effects of structural characteristics,
optical and electrical properties ...
Effective thermal conductivity of loose particulate systems
(1996)
The effective thermal conductivity for several loose particulate insulation systems has been measured in the temperature range from 273 K–900 K and the results compared to those predicted from three different models. The ...
