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 […]
Nucleophilic Addition of Amines to Ruthenium Carbenes: ortho-(Alkynyloxy)benzylamine Cyclizations towards 1,3-Benzoxazines Abstract: A new ruthenium-catalyzed cyclization of ortho-(alkynyloxy)benzylamines to dihydro-1,3-benzoxazines is reported. The cyclization is thought to take place via the vinyl ruthenium carbene intermediates which […]
Comparative gas sensor response of SnO2, SnO and Sn3O4 nanobelts to NO2 and potential interferents Abstract: The gas sensor performance of single crystalline tin oxide nanobelts in different oxidation states (SnO2, SnO and Sn3O4), synthesized by […]
Structure, Morphology, and Optical Properties of (Cal(1-3x)Eu(2x)) WO4 Microcrystals Abstract: In this letter, we report the efficient, surfactant-free, microwave-hydrothermal method of synthesizing calcium europium tungstate [(Ca1-3XEu2X) WO4, x= 0, 0.05, 0.01, 0.02, and 0.04] microcrystals. The […]
Rapid Preparation of (BiO)(2)CO3 Nanosheets by Microwave-Assisted Hydrothermal Method with Promising Photocatalytic Activity Under UV-Vis Light Abstract: Crystalline (BiO)(2)CO3 nanosheets were synthesized by a rapid one-step reaction via microwave-assisted hydrothermal method using urea as a morphology […]
