Both enantiomers of an optically active trialkynyl(phenyl)methane (the key building blocks in the construction of a stable expanded cubane) have been prepd. The strategy involved the resoln. of a racemic intermediate by means of HPLC on a chiral stationary ...
We present an effective solution for the problem of contrast enhancement in phase-contrast microangiography, with the specific objective of visualising small (< 8 A mu m) vessels in tumor-related microangiogenesis. Different hydrophilic and hydrophobic con ...
TiO2 modified polyester photocatalysts were prepared by immersion. drying and curing of the polyester in TiO2 containing suspensions under different experimental conditions. The structure of TiO2 layers on the polyester varied according to the time of imme ...
Colloidal organic matter (COM) collected in small and large watercourse tributaries of the Negro River (Brazil) were fractionated and characterized by an asymmetrical flow field-flow fractionation (AFIFFF) coupled to UV and seven angle laser light scatteri ...
Colloidal organic matter from wastewater treatment plants was characterized and examined with respect to its role in metal distribution by using tangential flow ultrafiltration, liquid chromatography coupled with organic carbon and UV detectors, and an asy ...
An optimized capacitively coupled contactless conductivity detector for microchip electophoresis is presented. The detector consists of a pair of top bottom excitation electrodes and a pair of pickup electrodes disposed onto a very thin plastic microfluidi ...
A method based on the coupling of high resolution size-exclusion liquid chromatography using a polymer stationary phase with inductively coupled plasma mass spectrometry was developed to study the interactions of two metallodrugs - cisplatin and RAPTA-T - ...
Oxygen reduction catalyzed by cobalt(II) (2,3,7,8,12,13,17,18-octaethylporphyrin) [Co(OEP)] at soft interfaces is studied by voltammetry and biphasic reactions. When Co(OEP) is present in a solution of 1,2-dichloroethane in contact with an aqueous acidic s ...
In this work, molecular simulations were performed to evaluate the separation performance of two typical zeolitic imidazolate frameworks (ZIFs), ZIF-68 and ZIF-69, for CO2/N2, CO2/CH 4, and CH4/N2 mixtures. To do this, we first identified a suitable force ...
Surface plasmon resonance (SPR) was observed when a planar close-packed assembly of gold nanoparticles (Au NPs) is adsorbed at the water|1,2-dichloroethane interface. Aqueous gold nanoparticles, 13 or 16 nm in diameter, are deposited at the interface by ad ...
