Properties and Application Perspective of Hybrid Titania-Silica Patterns Fabricated by Inkjet Printing


, : Properties and Application Perspective of Hybrid Titania-Silica Patterns Fabricated by Inkjet Printing. Acs Applied Materials & Interfaces 7(30): 16177-16190

A hybrid titania-silica cold-setting sol has been developed that can be deposited onto a wide variety of surfaces without the need for high-temperature fixing and that is suitable for material printing deposition. Thin hybrid titania-silica coatings were patterned onto glass and PET substrates by inkjet printing. Well-defined hybrid titania-silica patterns, with thicknesses ranging from 40 to 400 nm, were fabricated by overprinting 1 to 10 layers. Excellent mechanical, optical, and photocatalytic properties were observed, making the reported material well suited for the fabrication of transparent self-cleaning coatings both on mineral and organic substrates. The printed patterns exhibit photoelectrochemical activity that can be further improved by thermal or photonic curing. A concept of fully printed interdigitated photoelectrochemical cells on flexible PET substrates utilizing the reported hybrid photocatalyst is disclosed as well.

The assessment of deforestation and the understanding of the processes involved at the local scale need the use of high-resolution (20-30 m pixels) satellite images (Landsat TM and MSS), together with field observations. At this scale, the pixel s...

The solubilization efficiency of N-methyl pyrrolidone (NMP) has been determined and compared to that of ethanol and propylene glycol for 13 poorly soluble drugs. NMP is found to be a more efficient solubilizer for all the drugs studied. The solubi...

Zero point corrections for the out-of-plane modes are also incorporated. Transition s...

We have characterized a UDP-GlcNAc:Gal beta-3-GalNAc (GlcNAc----GalNAc) beta-6-N-acetylglucosaminyltransferase from rabbit small intestinal epithelium by using freezing point depression glycoprotein as the acceptor.
