(1992)The UV-Visible absorption Spectra for the complexes cis and trans BrMn(CO)2dppm{P(OPh)3} dppm = Ph2PCH2PPh2 in several solvents are reported and an assignment of their bands is proposed. The cis isomer present one ...
-
(Elsevier, 2017)As a novel strategy to overcome some of the therapeutic disadvantages of 6-thioguanine (TG) and 6-mercaptopurine (MP), we propose the inclusion of these drugs in beta cyclodextrin (beta CD) to form the complexes beta CD-TG ...
-
(1988)The influence of the donor-acceptor properties of several solvents on the Cr(CO)5 group in the solid [Cr(CO)5·solvent] complexes has been examined by spectroscopic methods. Relationships were found between the acceptor ...

(Universidad de Chile, 2016)Las nanopartículas metálicas (NPsM), específicamente, las nanopartículas de oro (NPsAu) y las nanopartículas de plata (NPsAg), exhiben excelentes propiedades físicas, químicas y biológicas, intrínsecas a su tamaño ...
-
(MDPI, 2016)Cyclodextrin (CD) molecules form inclusion compounds (ICs), generating dimers that are capable of encapsulating molecules derived from long-chain hydrocarbons. The aim of this study is to evaluate the structural changes ...
-
(TAYLOR & FRANCIS LTD, 2010)This work presents the preparation of copper nanoparticles (CuNPs), using as support, inclusion compounds (ICs) formed by a-cyclodextrin (a-CD) with alkylamines as guests. These ICs provide a suitable environment to ...
-
(Springer, 2016)In the last decades, nanoparticles have been of great research interest due to their unique quantum size effect and optical, electronic, magnetic, and supramolecular properties. In recent year, the face-selective adhesion ...
