Intercalation compounds of layered materials for drug delivery use. II. Diclofenac sodium.
Intercalation compounds of ternary layered inorganic materials, synthetic mica (Na-TSM), with diclofenac sodium (DFS) and its drug release characteristics were investigated. Hygroscopic DFS was selected as a model drug to verify the anti-humidity and anti-oxidation of the intercalation compounds. Na-TSM powder was first mixed with the reduced-type phosphatidylcholine (H-PC) solution of chlorofo...
متن کاملSelective and low temperature transition metal intercalation in layered tellurides
Layered materials embrace rich intercalation reactions to accommodate high concentrations of foreign species within their structures, and find many applications spanning from energy storage, ion exchange to secondary batteries. Light alkali metals are generally most easily intercalated due to their light mass, high charge/volume ratio and in many cases strong reducing properties. An evolving ar...
متن کاملDecreasing the electronic confinement in layered perovskites through intercalation.
We show that post-synthetic small-molecule intercalation can significantly reduce the electronic confinement of 2D hybrid perovskites. Using a combined experimental and theoretical approach, we explain structural, optical, and electronic effects of intercalating highly polarizable molecules in layered perovskites designed to stabilize the intercalants. Polarizable molecules in the organic layer...
متن کاملIntercalation of well-dispersed gold nanoparticles into layered oxide nanosheets through intercalation of a polyamine.
Gold nanoparticles have attracted widespread interest in both materials chemistry and biomedical science because of their special electronic, magnetic, catalytic, and optical properties1,2 For these applications, it is important to be able to control the size, shape, and dispersion of the nanoparticles on a chemically diverse range of supports. Oxides are among the most interesting kinds of sup...
متن کاملChemical Modification of Niobium Layered Oxide by Tetraalkylammonium Intercalation
A modificação química do material lamelar K 4 Nb 6 O 17 foi investigada sistematicamente através da reação de sua forma protônica (H 2 K 2 Nb 6 O 17 ) em soluções alcalinas contendo os cátions tetrametilamônio (tma), tetraetilamônio (tea) ou tetrapropilamônio (tpa). A quantidade intercalada corresponde a 50% (para tma), 25% (para tea) e 15% (para tpa) da carga negativa do H 2 K 2 Nb 6 O 17 (con...
