We present an easy-to-use analytic toolbox for the calculation of short-time transport properties of concentrated suspensions of spherical colloidal particles with internal hydrodynamic structure, and direct interactions described by a hard-core or soft Hertz pair potential. The considered dynamic properties include self-diffusion and sedimentation coefficients, the wavenumber-dependent diffusi...

OBJECTIVE To evaluate the influence of solvent evaporation in the kinetics of water diffusion (water sorption-WS, solubility-SL, and net water uptake) and nanoleakage of adhesive systems. MATERIAL AND METHODS Disk-shaped specimens (5.0 mm in diameter x 0.8 mm in thickness) were produced (N=48) using the adhesives: Clearfil S3 Bond (CS3)/Kuraray, Clearfil SE Bond - control group (CSE)/Kuraray,...

A new and versatile, crown ether appended, chiral supergelator has been designed and synthesized based on the bis-urea motif. The introduction of a stereogenic center improved its gelation ability significantly relative to its achiral analogue. This low-molecular-weight gelator forms supramolecular gels in a variety of organic solvents. It is sensitive to multiple chemical stimuli and the sol-g...

Abstract In this work, we present a model, based on rough hard-sphere theory, for the tracer diffusion coefficients of gaseous solutes in non-polar liquids. This work extends an earlier model developed specifically carbon dioxide hydrocarbon liquids and establishes general correlation The considered were light hydrocarbons, dioxide, nitrogen argon, while solvents all Application requires knowle...

abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...

Dioxygen (O(2)) and other gas molecules have a fundamental role in a variety of enzymatic reactions. However, it is only poorly understood which O(2) uptake mechanism enzymes employ to promote efficient catalysis and how general this is. We investigated O(2) diffusion pathways into monooxygenase and oxidase flavoenzymes, using an integrated computational and experimental approach. Enhanced-stat...

Monolayers functionalized with tricarbonyl1,10-phenanthroline rhenium chloride (RePhen(CO)3Cl) are studied in the presence of a variety of polar organic solvents (chloroform, tetrahydrofuran, dimethylformamide, acetonitrile), hexadecane, and water. The headgroup, RePhen(CO)3Cl, is soluble in the bulk polar organic solvents but not in hexadecane or water. The surface structural dynamics are stud...
