Exempel på hur man kan använda SOL-GEL i en mening

• Sols are often used in the sol-gel process, in which a sol is converted into a gel through the addition of a crosslinking agent.
• It was followed by development of laser glass, infra-red transmitting filters, synthetic quartz single crystal, high temperature protective enamels, high alumina ceramic seals and spacers, work in the field of optical fibre for telecommunications, sol-gel processing of glass and ceramic materials, production of glass fibre-based composites and application of ceramic materials in electronics.
• Spin coating is widely used in microfabrication of functional oxide layers on glass or single crystal substrates using sol-gel precursors, where it can be used to create uniform thin films with nanoscale thicknesses.
• Common techniques are physical vapor deposition (which includes evaporative deposition and ion beam assisted deposition), chemical vapor deposition, ion beam deposition, molecular beam epitaxy, sputter deposition, and sol-gel deposition.
• Silicon nitride nanowires can also be produced by sol-gel method using carbothermal reduction followed.
• The locomotion of Amoeba proteus exhibits chaotic dynamics described by a low-dimensional chaotic attractor with a correlation dimension around 3-4, indicating that the seemingly random movement arises from deterministic cooperative interactions among a small number of processes like sol-gel transformations, cytoplasmic streaming, and calcium-mediated reactions.
• The use of nanoparticles and nanofibers to produce specialized nanofabrics became a subject of interest after the sol-gel and electrospinning techniques were fully developed in the 1980s.
• In sol-gel routes, an amorphous precursor is calcined at 300-600 Celsius to remove organic residuals and to promote crystallization of the bismuth ferrite perovskite phase, while the disadvantage is that the resulting powder must be sintered at high temperature to make a dense polycrystal.
• Bridged polysilsesquioxanes are most readily prepared from clusters that contain two or more trifunctional silyl groups attached to non-hydrolysable silicon-carbon bonds, with typical sol-gel processing.
• Moreover, it has been shown that advanced melting effects can lead to a dramatic skew towards smaller pores in PSDs for mesoporous sol-gel silicas, determined from cryoporometry melting curves.
• In synthesizing core shell nanoparticles, scientists have studied and found several wet chemical methods, such as chemical precipitation, sol-gel, microemulsion and inverse micelle formation.
• Sol-gel science (sol-gel chemistry, nanostructured oxide films and powders, inorganic-organic hybrids, nanocomposites, oxide nanotubes).
• Gadolinium acetylacetonate, along with cerium acetylacetonate, can be used as precursors to synthesize gadolinia-doped ceria (GDC) gel powders using the sol-gel method.
• Methods of synthesis have included precipitation, hydrothermal treatment, sol-gel, spray pyrolysis technique (SPT), combustion and nanocasting using cerium sources such as cerium nitrate, ceric ammonium nitrate, cerium oxalate, cerium carbonate and cerium hydroxide.
• It includes degumming via sonification, which controls the rapid sol-gel transition of silk fibroin to form a hydrogel, regulating the protein structure to obtain protein-based materials.
• In particular, his research interests include the synthesis of crystalline metal oxide nanoparticles, heterostructures, hybrid materials and thin films by novel nonaqueous sol-gel routes, their assembly, and the study of their physical properties such as optical, electrical, electrochemical, magnetic, catalytic, gas sensing.
• Sol-gels can also be formed into monoliths, or columns, which are larger structures of sol-gel, unlike the typical thin layer.
• The preparation of silica aerogels typically involves three distinct steps: the sol-gel transition (gelation), the network perfection (aging), and the gel-aerogel transition (drying).
• Through sol-gel synthesis and freeze-casting, she examines stress-induced shape memory and superelastic effects in oligocrystalline zirconia systems, addressing the volume change issue that causes premature cracking in bulk systems.
• He developed a sol-gel dispersant of single wall carbon nanotube, producing highly transparent conductive films and stretchable electrodes.
