nano-cus powders were synthesized with chemical solution method. xrd and sem and spectrophotometry were used for characterization of the cus powders. xrd analysis indicated that tetragonal cus was the main phase with particle size of 16.2nm and little cu2s phase was present. scanning electron microscopy (sem) analysis revealed that powder was plate like and had very little aspect ratio in morph...

Nifedipine (NIF), a 1,4-dihydropyridine calcium channel antagonist, undergoes photo-degradation to dehydro-nifedipine (DNIF) upon exposure to ultraviolet (UV) light and to the nitroso analogue of dehydro-nifedipine (NDNIF) when exposed to sunlight or some kinds of artificial lights. NIF photo-degradation products do not contribute to clinical activity, thus prevention of photo-degradation of NI...

Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

BACKGROUND Various micropatterned surfaces capable of guiding the selective adhesion of biomolecules such as proteins and cells are of great interests in biosensor, diagnostics, drug screening, and tissue engineering. In this study, we described a simple photo-patterning method to prepare micro-patterned films for stem cell patterning using anthracene containing polymers (PMAn). This micro patt...

Based on three empirical studies of user experience in photologs, this paper introduces the concept of selective indulgence as part of user behaviour when lurking and sharing photographs. Displaying personal and domestic photographs in the public domain invites both acquaintances and unknown audiences. Despite the apparently limited communication offered by photologs, the studies reveal how par...

Protein capped metal nanoclusters gained a lot of recent attention due to their wide range applications. However copper are difficult synthesize tendency undergo oxidation. Here we successfully synthesized stable, biocompatible lysozyme protected Cu nanocluster (Lys-Cu NC) using an optimized green one-pot protocol under aqueous condition at room temperature. The showed strong photoluminescence ...

Lasers with wide tunability and tailored linewidth are key assets for spectroscopy research applications. We show that diamond, when configured as a Raman laser, provides agile access to broad range of wavelengths while being capable efficient selective photo-excitation atomic species suitable spectroscopic applications thanks its narrow linewidth. demonstrate the use compact diamond laser ion ...
