Influence of synthesis temperature on morphology of SBA-16 mesoporous materials with a three-dimensional pore system, Abstract Spherical particles of mesoporous silica SBA-16 with cubic Im3m structure were synthesized at low pH using Pluronic F127 as template and TEOS as silica source. The diameter of the spherical particles can be controlled in the range of 0.5 – 8 µm by varying synthesis temp...

Tissue-derived cultured cells exhibit a remarkable range of morphological features in vitro, depending on phenotypic expression and environmental interactions. Translation of these cellular architectures into inorganic materials would provide routes to generate hierarchical nanomaterials with stabilized structures and functions. Here, we describe the fabrication of cell/silica composites (CSCs)...

The fabrication of mesoporous silica films with well-defined morphologies offers tremendous opportunity for device structures. In particular the generation of a mesoporous silica film with cylindrical nanochannels of prescribed diameters oriented normal to the substrate holds great promise for applications in catalysis, bio-molecular separations, sensors, photonics, synthesis of aligned metalli...

Uncontrolled population growth and increased consumption of fossil fuels have led to the emission of pollutants and greenhouse gases. This is mostly a concern for reducing emissions of greenhouse gases, such as carbon dioxide because of its impact on global climate change1,2. The presence of carbon dioxide in the natural gas mixture can lead to lower heating value of gas, corrosion of processin...

Pre-shaped mesoporous amorphous rice husk ash (RHA) and MCM-41 derived from RHA as a silica source were transformed into MFI-type zeolites using two different structure-directing agents. Tetrapropylammonium hydroxide (TPAOH) was utilized as an alkali source for silica dissolution and structure control during the direct transformation of RHA into zeolite. A monopropylamine (PA)-containing alkali...

A novel method of preparing the macrporous nickel coating was described. The macrporous nickel coating was fabricated by employing nano-silica as the template. The effects of technological conditions and the concentration of the additives on the surface quality of coating were investigated, the nano-silica was characterized transmission electron microscopy (TEM) and laser particle size analyzer...
