abstract = {Evidence of guest migration in alpha-cyclodextrin-octylamine (alpha-CD-OA) inclusion compound (IC) generated via plasmonic heating of gold nanoparticles (AuNPs) has been studied. In this report, we demonstrate local effects generated by laser-mediated irradiation of a sample of AuNPs covered with inclusion compounds on surface-derivatized glass under liquid conditions by atomic force microscopy (AFM). Functionalized AuNPs on the glass and covered by the ICs were monitored by recording images by AFM during 5 h of irradiation, and images showed that after irradiation, a drastic decrease in the height of the AuNPs occurred. The absorption spectrum of the irradiated sample showed a hypsochromic shift from 542 to 536 nm, evidence suggesting that much of the population of nanoparticles lost all of the parts of the overlay of ICs due to the plasmonic heat generated by the irradiation. Mass spectrometry matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) performed on a sample containing a collection of drops obtained from the surface of the functionalized glass provided evidence that the irradiation lead to disintegration of the ICs and therefore exit of the octylamine molecule (the guest) from the cyclodextrin cavity (the matrix).},

abstract = {A new hybrid hetero nanocomposite, consisting of ZnO(myristic acid)/Ag-NPs, has been synthesized. The nanocomposite, made up of single ZnO nanosheets sandwiched between myristic acid self-assembled monolayers was synthesized and decorated with metal nanoparticles by chemical solution and tested in the photodegradation of methylene blue under UV light irradiation. The product displayed significant photocatalytic activity for degradation of the dye, and the activity was improved by a factor of three compared to bulk ZnO under similar conditions. The observed photodegradation efficiency is discussed in terms of the confinement of the semiconductor in the two dimensional structure, the adsorption ability of the organic component and the plasmonic absorption of Ag nanoparticles, which makes them act as electron wells, thus promoting charge separation and a reduced recombination rate.},

abstract = {Gold nanorods (AuNRs) stabilized by cetyltrimethylammonium bromide (CTAB) were deposited onto crystals of alpha-cyclodextrin (alpha-CD) inclusion compounds (ICs) that contained octanethiol (OT) as guest molecules. The nanodecoration was produced specifically at the 001 crystal planes through interaction between the -SH groups of the ICs and the AuNRs.},
