Polvos cerámicos de Sm2O3 dopados y mezclados con europio se obtuvieron a partir la formación cloruros samario través ruta sol-gel citrato. Este trabajo reporta influencia los iones en las propiedades estructurales luminiscentes cerámicas Sm2O3:Eu3+ (coordenadas CIE) variando el Eu3+ 10 50% mol. Las características químicas, morfológicas fueron establecidas por FTIR XRD, revelando presencia ban...
In this paper, preparation method of unsymmetrical di-methyl hydrazine with nano aluminum particles (50 and 130 nm) has been investigated. One of the important aspects of the research is the uniform dispersion of the nano particles in the fuel gel. Homogeneity of the fuel influences the quality of propellant combustion. The results showed that the combination of ultrasonic-mechanical-magnetic a...
preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...
b-cyclodextrin glucosyl transferase (b-cgtase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. the conventional method for detection of b-cgtase activity is based on detecting starch hydrolysis by iodine staining. this method reveals all amylolytic enzymes, but can not discriminate them. in the present study, we introduce a new method for specific detec...
