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 […]
