10 to 25-fold increase in the transport superconducting critical current density of spark-plasma sintered Bi-2223 superconductors Abstract: Pre-reacted powders of (Bi-Pb)(2)Sr2Ca2Cu3O10+delta (Bi-2223) were consolidated by using the spark plasma sintering (SPS) technique under vacuum and at […]
A comparison of charge-transfer mechanisms at rotated disk electrode for biomimetic binuclear and tetranuclear oxo-manganese complex in aqueous solution Abstract: Many high-valence multinuclear mu-oxo-bridged manganese complexes have been synthesized to mimic the active site of the […]
Degree of conversion of different composite resins photo-activated with light-emitting diode and argon ion laser Abstract: This study evaluated the degree of conversion (DC%) of one experimental and different brands of composite resins light-cured by two […]
Insights into electrodegradation mechanism of tebuconazole pesticide on Bi-doped PbO2 electrodes Abstract: The effect of the Bi doping of PbO2 coatings on the electrochemical degradation of the pesticide tebuconazole (TBC) was investigated. The insertion of 8% […]
Oscillatory Electro-oxidation of Methanol on Nanoarchitectured Pt-pc/Rh/Pt Metallic Multilayer Abstract: The oscillatory electro-oxidation of methanol was studied on polycrystalline Pt-pc and Pt-pc/Rh-2.0/Pt-1.0 metallic multilayers. The surfaces investigated consisted of 1.0 Pt outlayer surface deposited onto 2.0 […]
Antimicrobial photodynamic therapy against pathogenic bacterial suspensions and biofilms using chloro-aluminum phthalocyanine encapsulated in nanoemulsions Abstract: Antimicrobial photodynamic therapy represents an alternative method of killing resistant pathogens. Efforts have been made to develop delivery systems for […]
Local structure and hybridization states in Ba0.9Ca0.1Ti1-xZrxO3 ceramic compounds: Correlation with a normal or relaxor ferroelectric character Abstract: This paper reports on a multi-edge X-ray absorption analysis to elucidate how the substitution of Ti4+ by Zr4+ […]
Surface treatment of dental porcelain: CO2 laser as an alternative to oven glaze Abstract: This work tested continuous CO2 laser as a surface treatment to dental porcelain and compared it to oven glaze (auto-glaze) by means […]
A joint experimental and theoretical study on the electronic structure and photoluminescence properties of Al-2(WO4)(3) powders Abstract: In this paper, aluminum tungstate Al-2(WO4)(3) powders were synthesized using the co-precipitation method at room temperature and then submitted […]
A large red-shift in the photoluminescence emission of Mg1-xSrxTiO3 Abstract: In this letter, we report a detailed study of the influence of the synthesis and the optical properties of Sr-doped MgTO3 powders synthesized via a polymeric […]
