The silica coating has attracted much attention because of its superior corrosion resistance with almost no harm to human health and to the environment. In this study, a two layered silica film was tried to get an enhanced corrosion resistance. The silica film was prepared on the hairline finish 304 stainless steel surfaces by-a-spray- and subsequent-dip-coating process. The spray coating solution...... hiện toàn bộ

An ordered NiO/ZnO heterojunction electrochemical electrode was prepared on an FTO substrate by using the spin-coating method. XRD patterns confirmed the ZnO NRs of varying lengths and NiO NPs of varying sizes are grown in the same manner as hexagonal wurtzite and cubic crystal structures, respectively. An important outcome is that both the crystal structures are fused together as a heterostructur...... hiện toàn bộ
Nonlinear effects in chromophore doped sol-gel photonic materialsJournal of Sol-Gel Science and Technology - Tập 9 - Trang 169-181 - 1997

Linear and nonlinear optical effects have been studied in chromophore-doped gel hosts. Tetra-4-sulfonatophenylporphyrinatocopper(II) (CuTPPS), and 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]-naphth[2,1-b][1,4]oxazine] (SP spirooxazine) species were entrapped within porous aluminosilicate hosts. Optical limiting effects and radiative up-conversion behavior in the CuTPPS-doped materials are...... hiện toàn bộ
Preparation and antibacterial property on silver incorporated mesoporous bioactive glass microspheresJournal of Sol-Gel Science and Technology - Tập 75 - Trang 279-290 - 2015
Ratiya Phetnin, Sirirat Tubsungnoen Rattanachan
In this study, the antibacterial property of silver-incorporated mesoporous bioactive glass microspheres (Ag-MBGMs) was investigated. The samples belonging to the 80SiO2·(15 − x)CaO·5P2O5·xAg2O system where 0 ≤ x ≤ 5 mol% were successfully prepared for bone regeneration and drug carrier applications. The obtained samples were evaluated by X-ray diffraction (XRD), transmission electron microscope (...... hiện toàn bộ
Effect of seeded substrates on hydrothermally grown ZnO nanorodsJournal of Sol-Gel Science and Technology - Tập 50 - Trang 456-464 - 2009
Sunandan Baruah, Joydeep Dutta
We report a study on the effect of seeding on glass substrates with zinc oxide nanocrystallites towards the hydrothermal growth of ZnO nanorods from a zinc nitrate hexahydrate and hexamethylenetetramine solution at 95 °C. The seeding was done with pre-synthesized ZnO nanoparticles in isopropanol with diameters of about 6–7 nm as well as the direct growth of ZnO nanocrystallites on the substrates b...... hiện toàn bộ
Stabilization of quercetin-functionalized silica gel against hydrolysis by blocking silanol groups with TiO2 or ZrO2 and its application for the removal of Hg(II)Journal of Sol-Gel Science and Technology - Tập 57 - Trang 57-67 - 2010
Khaled S. Abou-El-Sherbini, Detlef Schiel, Rainer Stosch, Peter Weidler, Wolfgang H. Höll
Free silanol groups of silica-gel functionalized with quercetin (QSG) were blocked with TiO2 or ZrO2 to produce TiO2-QSG and ZrO2-QSG, respectively. The silica materials were characterized by infrared, Raman spectra, thermogravimetric, elemental analyses, magic angle spinning 13C-nuclear magnetic resonance, BET specific surface area measurements and inductively coupled plasma—optical emission spec...... hiện toàn bộ

Organic–inorganic hybrid materials have been used as fillers to reinforce dental resin composites, which require strengthening to improve their performance in large stress-bearing applications such as crowns and multiple-unit restorations. Homogeneous organic–inorganic hybrid materials with high performance were prepared by mixing 3-methacryloxypropyltrimethoxysilane (MPTS) and tetraethylorthosili...... hiện toàn bộ
