Nanosized precipitates in H13 tool steel low temperature plasma nitriding
Heterogeneous photocatalytic Cr(VI) reduction with short and long nanotubular TiO2 coatings prepared by anodic oxidation
(Pergamon-Elsevier Science Ltd, 2018-01)
Nanotubular TiO2 coatings prepared by anodic oxidation of titanium were evaluated for the first time in the photocatalytic Cr(VI) reduction in the presence of EDTA. Small nanotubes (SN) were prepared by using aqueous ...
Removal Of Cr(vi) From Aqueous Solution Using Brick Kiln Chimney Waste As Adsorbent

Cr(III) exchange on zeolites obtained from kaolin and natural mordenite
Zeolites with high Cr(III) exchange capacity were synthesized from kaolin and natural mordenite. The intermediate phases and final products were characterized by X-ray diffraction, FTIR spectroscopy, scanning electron ...
Síntese via método dos precursores poliméricos e caracterização multifuncional de nanopartículas de SnO2 modificadas com zinco-nióbio e cobalto-nióbio
(Universidade Estadual Paulista (UNESP), 2017-08-24)
O objetivo deste projeto foi sintetizar dois sistemas à base de dióxido de estanho (SnO2), sendo um dopado com zinco e nióbio e outro dopado com cobalto e nióbio, respectivamente (Zn,Nb)-SnO2 e (Co,Nb)-SnO2, e realizar as ...
