Uptake of alkane (C5-C9) and alcohol (C4-C7) solutes by both strong acid cation exchange resins and strong base anion exchange resins in aqueous medium has been studied. The amount of solute taken up by resins is directly proportional to the solute concentration equilibrium with resins. Hydrophobic interaction between the solute and the resin matrix appears to play an important role in the upta...

Alkyd resins are amongst the most important and widely used resins in coating sectors. In this communication we report on preparation of alkyd resins emulsified by grafted acrylic resins on their fatty acid moieties. Both high-shear mechanical homogenizer and ultra-sonic sonicator were used step-wise to disperse the alkyd resin and acrylic based monomers in aqueous media. The resins are of nano...

We previously studied the mechanism underlying the adsorption of oral bacteria on the surfaces of dental prosthetic materials such as ceramics and resins in vitro. The aim of the present study was to examine bovine serum albumin (BSA) adsorption on crown composite resin surfaces by means of zeta potential. We measured the zeta potentials of resins alone, BSA alone, and resins after BSA adsorpti...

Poly(methacrylate) matrices for affinity resins were designed and synthesized based on our previous results that nonspecific protein absorption on affinity resins strongly depended on their hydrophobic property. The novel affinity resins bearing FK506 (6a, 6b) captured specific binding protein, FKBP12, with a small amount of nonspecific binding proteins. The amount of nonspecific binding protei...

Effects of abrasive and fiber components in a medium on the wear behavior of composite resins were evaluated. Calcium diphosphate and methyl cellulose were included in the medium as abrasive and fiber components respectively. A range of 0, 4, or 8% abrasive- or fiber-containing media were applied on a composite resin specimen during a simulated occlusal wear test. Four composite resins, Clearfi...

This paper describes the synthesis and characterization of epoxy resins based on (hexafluoroisopropylidene)diphenol (EFN) and p,p’-isopropylidenebisphenol (EBN), respectively and 4, 4’(hexafluoroisopropylidene)dipthalic-imideamine (IMAM), a curing agent. The synthesized epoxy resins and IMAM curing agent were characterized by Fourier Transform Infrared (FTIR) and 1H Nuclear Magnetic Resonance (...

Hops (Humulus lupulus L. Cannabaceae) is an economically important crop, that has drawn more attention in recent years due to its potential pharmaceutical applications. Bitter acids (prenylated polyketides) and prenylflavonoids are the primary phytochemical components that account for hops resins medicinal value. We have previously reported on utilizing untargeted NMR and MS metabolomics for an...

A survey is given on the various options to seal water ingress from strata and from concrete structures by injecting different types of resins showing the scope and limits of the individual grouts. The report covers methacrylates and polyurethane hydrogels, one and two component polyurethane resins as well as silicate isocyanate resins. The use of fast reacting two component polyurethane resins...
