CaP Precipitation on Titanium under UV Lighting and Effect of Urea Concentration

Qing Zhou, Liang-Liang Zhang, Ming-Li Xie

Abstract: This paper reports the precipitation of calcium phosphate (CaP) on alkaline hydrothermally treated titanium alloy under ultraviolet (UV) lighting. Urea (NH2CONH2) with different concentrations were added into a simulated body fluid buffered by sodium lactate. CO2 and NH3 gas release during immersion tests were detected. The [...] Read more.

Study on effect of Cu integration and Oxygen vacancy/defect creation in electronic properties of TiO2 photocatalyst using first principles calculations

R. Gandhimathi, R. Vidhya, R. Karthikeyan

Abstract: In this investigation, it was proposed to analyze the optimized geometry, density of states (DOS) and electronic band structures of copper (4.16%, 4.16%+oxygen vacancy & 8.33%) doped Titanium Dioxide (Cu-TiO2) photocatalysts using density functional theory corrected for on-site Coulombic interactions (DFT+U). The photocata [...] Read more.

Controlled Drug Release from Sodium Alginate Film Dosage Forms

Yoshifumi Murata, Sayaka Kimura, Kyoko Kofuji, Chieko Maida

Abstract: Film dosage forms (FDs) prepared using water-soluble polymers can efficiently deliver drugs to local disease sites. In the present study, we prepared FDs by incorporating a model drug rebamipide into a film made of sodium alginate (Alg-Na), comprising an alginic acid hydrolysate and α-L-guluronic acid (G) block (G-block), a [...] Read more.

Test for Reconditioning RA Waste with Simulated Bitumen and Concrete in a 1,2MW Plasma Test Facility-20092

Jan Deckers, Jurgen Hansen

Abstract: The operation and maintenance of nuclear power plants, the non nuclear fuel cycle, etc generate low-level radioactive waste which, along with the historical radioactive waste from past nuclear activities, needs to be treated and stored, awaiting final disposal. Plasma technology offers a very effective way of treating this [...] Read more.
