Ni/Ni oxides nanoparticles with potential biomedical applications obtained by displacement of a ... (2008)A new synthesis and stabilization method was developed for paramagnetic nanoparticles composed of nickel and nickel oxides. Nickel/nickel oxides nanoparticles were synthesized by a method based on ligand displacement of ...
-
(2008)The characteristics of the seeds from Chilean palm and the detailed composition of its fat are studied starting from 4 lots of seeds from the two regions being the major producers of Chilean palm seeds. From the proximate ...
-
(2009)The reaction of (2,6-diisopropyl-phenyl)-acetimidoyl chloride or (2,6-dimethyl-phenyl)-acetimidoyl chloride with 2,6-dimethylaniline in the presence of triethylamine yields a mixture of isomers N′-(2,6-diisopropyl-phenyl ...
-
(2008)Novel liquid crystalline materials based on chiral calamitic 1,2,4- and 1,3,4-oxadiazole derivatives were synthesized and their thermotropic mesomorphism investigated by polarizing optical microscopy and differential ...
-
(2009)Bioactive compounds of pulp (CP) and ethanolic (CE) extracts of the cactus pear (Opuntia ficus-indica) were encapsulated with maltodextrin (MD) or inulin (I). A 22 statistical factorial design was then used to study the ...
-
(2009)In rat ovary chronic cold stress increases sympathetic nerve activity, modifies follicular development, and initiates a polycystic condition. To see whether there is a relationship between the previously described changes ...
-
(2009)Computed bond lengths and angles of methyl ethyl and dimethyl triphenyl phosphonium ylidic diesters, 1b, c, respectively, are similar to those in the crystal, as for the diethyl ester, 1a, where both acyl oxygens are anti ...
-
(2009)An oxygen radical absorbance capacity (ORAC) method based on pyrogallol red bleaching (ORAC-PGR) was used to evaluate the scavenging activity of berry extracts (blackberry, blueberry, and raspberry). Among berry extracts, ...
-
(2008)A novel series of 2-benzothiophenealkylpiperazine derivatives 11 (a-d) with potential affinity at 5-HT1A serotonin receptors have been synthesized via solvent-free, microwave-promoted Michael addition of benzo[b]thiophene ...
-
(2008)The Rh-catalysed hydroformylation of isopropylidenecyclohexane derivatives obtained by intramolecular diene cyclisations affords the corresponding aldehydes in good yields and in a completely chemo- and regioselective ...
-
(2006)Transmissible Spongiform Encephalopathies are fatal and infectious neurodegenerative diseases characterized by extensive neuronal apoptosis and the accumulation of an abnormally folded form of the cellular prion protein ...
-
(1999)St I is a toxin present in the Caribbean Sea anemone Stichodactyla helianthus which is highly hemolytic in the nanomolar concentration range. Exposure of the toxin to free radicals produced in the pyrolysis of 2,2′ ...
-
(1988)The enthalpies of the reaction between glutathione and amoxycillin have been measured directly using a flow microcalorimeter. Comparative results are obtained by using an ac polarographic method previously developed in our ...
-
(2008)Properties of inclusion complexes between morin (M) and β-cyclodextrin (βCD), 2-hydroxypropyl-β-cyclodextrin (HPβCD) and Heptakis (2,6-O-di methyl) β-cyclodextrin (DMβCD) such as aqueous solubility and the association ...
-
(1974)Second order perturbation theory (SOP) has been used to introduce electronic correlation effects on CNDP/2 calculated quantities like stabilization energy, proton potential curves, intermolecular dependence on distance and ...
-
(1975)Study of the visible absorption and circular dichroism spectra of mixed complexes formed by copper(II), an optically active amino acid anion and a phenanthroline or dipyridyl moiety, shows that although the absorption ...
-
(1980)The photochemistry of alkanals in dilute solutions and in the presence of olefins and hydrogen donors was analysed and the results obtained are discussed taking as reference the photochemical behaviour of the alkanones. ...
-
(1978)Kinetic studies of the [Co(phen)3] (ClO4)3 2H2O nitromethane pyridine reaction were made spectrophotometrically, by recording the appearance of a new absorption band at 474 nm. The reaction is first order with respect to ...
-
(1979)Mössbauer spectroscopy as a function of temperature of Fe(II)(N,N′-dicyclohexyl-thiourea)6(ClO4)2(FeDCTU) shows the existence of two isomeric forms A and B which coexist in the temperature range 200 < T < 300 K. The relative ...
