Avaliação da estimativa de substituição de Fe por Al em hematitas de solos
(1998) [Artigo de periódico]Hematitas de nove solos e uma de itabirito foram tratadas com NaOH 5 mol L-1 e analisadas por difratometria de raios X (DRX), usando varredura escalonada (0,02°2q/20 s). Determinaram-se o espaçamento d e as dimensões a0 e ... -
Characterization study of electric arc furnace dust phases
(2006) [Artigo de periódico]Electric arc furnace dust (EAFD) is a solid waste generated in the collection of particulate material during steelmaking process in electric arc furnace. The aim of this work is to carry out a chemical and structural ... -
Ion irradiation-induced foams in antimonide binary alloys : a combination of small energy bandgap with giant surface-to-bulk ratio
(2020) [Artigo de periódico]This is a short review about the ion irradiation-induced foams in antimonide films. III–V semiconductors like InSb and GaSb can be transformed into solid foams with nanometric dimensions upon irradiation with swift heavy ... -
Photocatalytic studies of tio2/sio2 nanocomposite xerogels
(2017) [Artigo de periódico]The use of titania-silica materials in photocatalytic processes has been proposed as an alternative to the conventional TiO2 catalysts, in order to facilitate the separation of products after the reaction. However, despite ...
