Inkjet printing of nanosized silver colloids.
A water-based conducting ink, composed of well dispersed nano-silver particles, has been successfully inkjet printed using an ordinary commercial printer. The silver colloids with diameter around 50 nm were dispersed in a water and diethylene glycol cosolvent system. The 25 wt% silver ink had a viscosity of about 7.4 cP and surface tension of 33.5 dyn cm(-1) at 20 degrees C, which is appropriat...
متن کاملOn the Raman shift in nanosized crystals
An analytical form of the Raman shift dependence on size of nanocrystals is presented. Based on the hard confinement model, it works in those cases where the average phonon curve shows a quadratic dependence on the phonon quasi-momentum in the range of interest. PACS : 78.67.Bf, 78.30.-j, 78.30.Am, 36.20.Ng Raman spectroscopy is an important tool in gathering information about molecular and cry...

متن کاملNanosized anatase TiO2 single crystals for enhanced photocatalytic activity.
Nanosized anatase TiO(2) single crystals with 18% {001} facets have a raised conduction band minimum by 0.1 eV, and exhibit photocatalytic activity both for generating *OH radicals and for splitting water into hydrogen that is markedly superior--by factors of 5.6 and 8.2, respectively--to reference ca. 3 microm anatase TiO(2) with 72% {001} facets.
متن کاملApplication of Sonochemistry for Formation of Nanosized Silver and Silver/Hydroxyapatite Composite Particles
Development of nanotechnology during last few decades gave significant contribution to different areas of research especially in biomedical sciences and improved characteristics of many biomaterials allowing their commercial application [1,2]. One of the representative examples is the development of nanomedicine, a new field of medical research which opened the possibility for interactions betw...
