Abstract. Pd/H-Beta catalysts with different silica-to-alumina ratio prepared by an impregnation method have been studied by XANES/EXAFS, IR, XRD and TEM. It was shown that palladium in calcined Pd/H-Beta samples exists as palladium oxide that can be easily reduced to Pd metal. The catalysts were tested in selective oxidation of piperonyl alcohol to piperonylaldehyde at 80 oC. The Pd/H-Beta…
Drug delivery is a critical aspect in formulation because proper selection of the delivery system can control the bioavailability, the concentration profile, and undesirable side effects. Dendrimers pose an exciting opportunity for chemists to fabricate macromolecular structures with a specifically tailored function. They are the same size as serum protein and hence are capable of directly ente…
