Adsorción de compuestos clorados en sílices dopadas: Cu/SiO2, Fe/SiO2 y Ag/SiO2 para aplicaciones ambientales
(Benemérita Universidad Autónoma de Puebla, 2019-11)
"Éste proyecto reside en la disminución del impacto de los compuestos organoclorados (COs) mediante la técnica de cromatografía de gases, usando como adsorbente monolitos de SiO2, Cu/SiO2, Fe/SiO2 y Ag/SiO2, de ésta forma ...
Overview of Al-Si alloys for additive manufacturing and prospects
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia de Materiais - EMa, 2021-11-18)
Additive manufacturing (AM) has emerged in recent years for enabling the generation of parts with highly complex geometries. Due to the nature of the AM process, which causes alloys to experience a complex thermal history ...
alpha-SiAlON-SiC composites obtained by gas-pressure sintering and hot-pressing
(Elsevier B.V., 2007-07-06)
The objective of this work was the obtaining in situ of alpha-SiAlON-SiC composite, using an alternative rare-earth oxide mixture, RE2O3, as sintering additive, by two different sintering processes. As sintering additive, ...

X-ray diffraction study of crystalline Si nanocluster formation in annealed silicon-rich silicon oxides
(American Institute of Physics, 2006-12)
The formation and subsequent growth of crystalline silicon nanoclusters (Si-ncs) in annealed silicon-rich silicon oxides (SRSOs) were studied by glancing angle x-ray diffraction. SRSO samples with Si concentrations (y) of ...
Isotopic determination of silicon by mass spectrometry in plants and soils labeled with Si-30
(TAYLOR & FRANCIS INC, 2008)
A method for isotopic determination of silicon by mass spectrometry in plants and soils labeled with Si-30 is reported. The development of this method is for use with studies involving the physiological process of absorption, ...
Silicon foliar application on nutrition and growth of Phalaenopsis and Dendrobium orchids
(2018-11-18)
Foliar application of silicon can be beneficial to orchid growth, but it may also impair growth depending on the source and solution concentration. Due to the lack of information on silicon toxicity in long-term orchid ...
