Size-selective incorporation of CdS nanoparticles into mesoporous silica
Article Abstract:
CdS nanoparticles were produced in reverse micellar systems and incorporated into thiol-modified MCM-41 (FM41) mesoporous material, of various pore sizes, designated as large, middle and small. A particle-sieving effect of the FM41 was found, in that the incorporation of the CdS nanoparticles was reduced by increased size of particle, and by a reduction in the pore size of FM41. The resulting CdS-FM41 composite indicated photocatalytic activity for H2 generation from water.

Effects of metal cation coordination on fluorescence properties of a diethylenetriamine bearing two end pyrene fragments
Article Abstract:
The effect of adding metal cations ([Zn.sup.2+], [Cd.sup.2+], [Cu.sup.2+], [Hg.sup.2+], [Ag.sup.2+]) on the fluorescence properties of a diethylenetriamine bearing two end pyrene fragments, L, which was studied in water showed L to behave as the first molecular switch capable of quenching pyrene excimer emission by the addition of all of these metal cations in water.
