In this research, magnetite coated with L-arginine modified silica (Fe3O4/SiO2-GPTMS-Arg) has been synthesized through a sol-gel process at a room temperature in two Routes. In Route 1, a precursor of sodium silicate solution (source of SiO2), 3-glycidoxy... see more

This paper presents a thermal based modified dynamic model of a Solid Oxide Fuel Cell (SOFC) for grid-connected systems. The proposed fuel cell model involves ohmic, activation and concentration voltage losses, thermal dynamics, methanol reformer, fuel ut... see more

Humidity sensing elements have been prepared via a sol-gel method on the basis of titanium n-butoxide, doped with ZnO. By this method Zn-modified titania films have been deposited on alumina substrates with interdigitated silver palladium electrodes and s... see more

Telah dilakukan penelitian tentang sintesis lapis tipis berbasis nanopartikel titania termodifikasi silika (TiO2-SiO2) secara sol-gel sebagai bahan antifogging untuk (i) mengetahui pengaruh temperatur kalsinasi terhadap energi band-gap, struktur dan ukura... see more

Sol-gel silica antireflective coatings (ARCs) with improved amphiphobicity were simply fabricated on BK7 glass substrates via fluorinated-poly(methylhydrogen)siloxane (F-PMHS) surface modification by the dip-coating method. The results of Fourier Transfor... see more

Titanium dioxide thin films were deposited using a Tween® surfactant modified non-aqueous sol-gel method onto fluorine doped tin oxide glass substrates. The surfactant concentration and type in the sols was varied as well as the number of deposited layers... see more

A review is devoted to recent achievements in development of anticancer drugs based on natural polysaccharide – gellan that possesses coil-helix conformational transition, sol-gel phase transition, thermo- and salt sensitivity. The characteristics of high... see more

Silica gel modified with 4-amino-5-hydroxy-2,7-naphtalenedisulphonate (SG-SO3-) has been applied for adsorption of Mg(II), Cd(II), and Ni(II) in aqueous medium. In addition, three thermodynamic parameters i.e. capacity, adsorption constant and energy of a... see more

Vaginal preparations, although generally perceived as safer most , still they are associated with a number of problems, including multiple days of dosing, dripping, leakage and messiness, causing discomfort to users and expulsion due to the self-cleansing... see more
