  2010 MAR 8 - (VerticalNews.com) -- According to recent research from Vilnius, Lithuania, "Nonequilibrium charge carrier relaxation dynamics in porous silicon was investigated by means of time-resolved photoluminescence and ultrafast transient reflectance."

  "Fluorescence band shift to the low energy side and intensity decay were observed during several initial nanoseconds under porous silicon excitation at 3.3 eV, and attributed to the spectral diffusion and trapped carrier recombination," wrote G. Juska and colleagues ...read more

  2010 MAR 8 - (VerticalNews.com) -- According to recent research from Singapore, Singapore, "Here, monolayer-protected gold and silver nanoparticles with extremely high solvent dispersibility (over 200 mg mL(-1) in water and glycols) and low coalescence temperature (approximately 150 degrees C, measured by the percolation transition temperature T-p) are developed, to reach conductivities better than 1 X 10(5) S cm(-1). These materials are suitable for inkjet and other forms of printing on substrates that may be solvent- and/or temperature-sensitive, such as for plastic electronics, and as bus lines for solar and lighting panels. ...read more

  2010 MAR 8 - (VerticalNews.com) -- According to a study from the United States, "The effect that the phase of the starting nanoseed titania (TiO2), the pH of the solvent solution, and the processing methodology employed have on the properties of the resultant TiO2 nanomaterials were explored. This led to the development of a new process to produce large-scale, phase pure, thin nanowires of TiO2 at high pH and nanosquares at low pH. ...read more
