Supramolecular reversible On-Off switch for singlet oxygen using cucurbit[n]uril inclusion complexes (American Chemical Society, 2017)A novel strategy to control the generation of singlet oxygen by a photosensitizer using cucurbit[n]urils inclusion complexes is shown herein, and the strategy has great potential for therapeutic applications. We show the ...

(2000)We report measurements of the resistivity (Formula presented) of a gold film 70 nm thick deposited on mica preheated to 300 °C in UHV, performed between 4 and 300 K, and measurements of the surface topography of the same ...
-
(2005)Surface-enhanced micro-Raman spectroscopy (micro-SERS) was used to detect traces of the hazardous pollutant polycyclic aromatic hydrocarbons (PAHs) pyrene and benzo[c]phenanthrene deposited onto a calix[4]arene-functionalized ...
-
(Taylor and Francis Inc., 2016)A modification to the traditional synthesis of reduced silver metal nanoparticles with hydroxylamine hydrochloride is proposed. The new colloid, obtained by decreasing the concentration of hydroxide and chloride ions, is ...

(2000)Experiments and three-dimensional numerical simulations are presented to elucidate the dynamics of granular material in a cylindrical dish driven by a horizontal, periodic motion. The following phenomena are obtained both ...
-
(2014)Inorganic fillers such as CaCO3 and clays are widely used as fillers to improve the mechanical and physical properties of polypropylene (PP). With the aim of improving simultaneously the stiffness and yield stress of PP, ...
-
(2003)Surface tension measurements have been made in aqueous solutions of anionic hemiesters of an alternating copolymer of maleic acid and styrene, MAS-n with n=0-12, in the presence of dodecyltrimethylammonium bromide, DTAB. ...
-
(2014)The molecular structure of the exo-3,6-dimethyl-3,6-epoxi-1,2,3,6-tetrahydrophthalimide (1), determined by X-ray diffraction analysis, as well as, its complete spectroscopic characterization and the synthesis and complete ...

Synthesis and Biological Screening of Novel Indolalkyl Arenes Targeting the Serotonine Transporter (Wiley, 2014)A series of functionalized indolylalkylarenes 3–16(a and b) were synthesized and their affinities for the serotonin transporter were investigated in vitro. Compounds 3–12(a and b) were obtained by nucleophilic substitution ...
-
(Taylor & Francis, 2016)The synthesis and phase characterisation of two homologous series of monomers of acrylic azo-compounds has been presented. The characterisation comprises polarising optical microscopy (POM), differential scanning calorimetry ...
-
(Hüthig & Wepf Verlag, 1998)The synthesis of a novel kind of form-retaining liquid crystalline crosslinked metallopolymer is reported. Copper(II) is complexed by Schiff's base units as part of a mesogenic side chain polymer. This leads to remarkable ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2002-12)A new Rhenium (I) and Ruthenium(II) bimetallic polipyridilcarbonil complex and the corresponding monometallic precursor complexes were prepared. The compounds were characterized physically and spectroscopically (Elemental ...
-
(JOHN WILEY & SONS, 2008-08)Novel ruthenium (II) complexes were prepared containing 2-phenyl-1,8-naphthyridine derivatives. The coordination modes of these ligands were modified by addition of coordinating solvents such as water into the ethanolic ...
