Abstract:

A technology designed for recycling photovoltaic (PV) cells at the end of their life was successfully used for the preparation of a nickel silicide catalyst. PV cells were mixed with magnesium scrap to produce magnesium silicide (Mg2Si), with almost total conversion under optimized conditions (400 °C, 5 Pa, 25 min), in a constructed semi-open tubular reactor. Subsequently, magnesium silicide was hydrolyzed by 25% phosphoric acid to produce a mixture of silicon hydrides, which were utilized as chemical vapor deposition (CVD) precursors for the preparation of a nickel silicide catalyst.

Abstract:

The rapid development of nanotechnology has opened up multiple areas of application of titanium silicide nanowires including microscopic fields, sensor and catalyst areas and electrode materials, as well as their potential applications in nanodevices. The preparation of titanium silicide nanowires can be summarized as top-down method and bottom-up method. Its necessary to find some simple and quick ways to prepare titanium silicide nanowires with the desirable pattern. Recent advances in manipulating titanium silicide nanowires are discussed with a focus on the progress of nanowire preparation

Histidine is an amino acid present in proteins involved in biosilica formation and often found in peptides identified during phage display studies but its role(s) and the extent of its involvement in the silica precipitation process is not fully understood.

We show that the presence of imidazole from PVI or P-His is able to catalyze sili

Abstract:

Structural control and morphological modification of a series of Si-based nanostructures were studied from the viewpoint of modifying the catalyst’s characteristics. The catalyst was modified from a liquid to a solid during its growth. The growth evolution of the faceted Si nanowires occurred via a vapor–liquid–solid mechanism followed by a silicide vapor–solid–solid mechanism. The shapes of the catalysts defined the shapes of the nanowires during the vapor–solid–solid growth. The catalyst was further modified by the deposition of MnCl2.

Unique nanowire growth was accomplished at 575 °C by the metal-induced growth (MIG) method. This involved a spontaneous reaction between metal and Si. The deposited metal worked as a catalyst layer to grow nanowires in the solid state. Various metals (Ni, Co, and Pd) were used in MIG nanowire fabrication, and the Ni-induced case was successful in demonstrating that metal species should be the dominant factor for growing nanowires. The Ni to Si composition was studied by energy dispersive spectroscopy showing the Ni diffusion inside the nanowire as well as the Ni silicide layer. The practical a

The possibility of using domestic Mg-silicate (sepiolite, white) as Si source and novolac resin (as carbon source), for synthesis of fine ?-SiC powder at relatively low temperatures (1673-1873 K), was demonstrated.

Carbothermal reduction process, which was used in this study, is greatly influenced by catalyst addition (FeCl3, FeSi).

The cell wall polymer callose catalyses the formation of silica in vitro and is heavily implicated in biological silicification in Equisetum (horsetail) and Arabidopsis (thale cress) in vivo . Callose, a β-1,3-glucan, is an ideal partner for silicification, because its amorphous structure and ephemeral nature provide suitable microenvironments to support the condensation of silicic acid into silica. Herein, using scanning electron microscopy, immunohistochemistry and fluorescence, we provide further evidence of the cooperative nature of callose and silica in biological silicification in rice,

The influence of the quantity of silanol in an active silicic acid solution (ASAS) on the growth rate of colloidal silica particles was investigated.

As expected, the particle growth rate was confirmed to be a function of the acid concentration in the water used to prepare the ASAS. In addition, when the entire process was conducted under basic conditions to obtain spherical particles, the initial basicity had a secondary influence on the particle growth

Abstract:

Silylation of isoquinoline with Me3SiCl/Li/THF or Me3SiCl/Mg/THF reagents has been studied. The choice of the metal and the experimental conditions govern the course of the silylation reaction and lead to new trimethylsilyl heterocyclic compounds.

Abstract:

Powders of catalysts from aluminides Fe and Co on a SiO2 support (33.3 wt. %) were obtained by mechano-thermal synthesis. The formation of large powder fractions (> 100 μm) was experimentally established. The fractions of these fractions for Fe – Al – SiO2 and Co – Al – SiO2 respectively amounted to ~ 43 % and ~ 55 %, which is a positive result for further catalytic studies. After annealing the powders at 700 and 900 °C in vacuum, the SiO2 support and compounds: Co27Al73 (close in composition to CoAl3, Co4Al13 type intermetallic compounds), Fe3Al intermetallic compound with iron silicide ty
