In this research, we propose a mass production method of gratings integrated with micro channels (GIMC) by means of an improved micro injection molding technique. The GIMC can be used together with a waveguide layer as a biochip in bio-medical assays. In the improved micro injection molding technique of this work, we fabricate an injection mold of gratings through the use of a nanoimprint and p...

Well-ordered mesoporous alumina materials with high surface area and a narrow pore size distribution were synthesized using a sol-gel based self assembly technique.

The encapsulation of ZnO nanoparticles (5 nm) coated by cyanobiphenyl units by the sol-gel technique leads to spherical ZnO@SiO2 nanoparticles displaying blue emission under UV excitation.

The sol-gel technique is earning the worldwide attention of researchers in the field of material science, due to its versatility in synthesizing inorganic ceramic materials at mild conditions. High purity, homogeneity, controlled porosity, stable temperature and nanoscale structuring are the most remarkable features offered by this method for generating highly sensitive and selective matrices t...

to improve the corrosion protection of copper metal, 0.01m concentration of 1h-1,2,4-triazole-3-thiol (tat) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (gptms) and tetraethoxysilane (teos). it was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. the tat-doped hybrid sol-gel coating was applied over the coppe...
