Abstract In this paper, the epoxy value of resin TDE-85 was measured by proton nuclear magnetic resonance ( 1 H-NMR) spectroscopy and tetraethylammonium bromide titration. Comparisons measurement results repeatability two methods show that NMR can be used to measure TDE-85. However, because high requirements for sample purity, when testing containing impurities, is worse than

PURPOSE The present study was aimed to evaluate the influence of implant contact ratio and stiffness of implant-surrounding materials on the resonance frequency analysis (RFA) values. MATERIALS AND METHODS Seventy resin blocks that had the different amounts (100, 50, 30, 15%) of resin-implant contact (RIC) were fabricated. Ten silicone putty blocks with 100% silicone-implant contact were also...

The solid-phase Edman degradation procedure as proposed by Laursen [ 1] is ideally suited to the evaluation of peptidyl-resin products resulting from Merrifield solid-phase synthesis [2,3] of peptides. Incomplete deprotection and incomplete coupling reactions which occur during synthesis have been detected using quantitative Edman degradation [4,5]. However, extended sequencing experiments were...

Abstract This work evaluates the purification of melon peel extracts obtained by two eco-friendly methods: autohydrolysis and sodium acetate/urea/water extraction (1:3:1.6), an alkaline deep eutectic solvent (DES). For that, sequential ethanol precipitation resin adsorption/desorption stages were proposed for separate recovery pectic phenolic fractions. In order to screen optimal conditions, in...

In the work, sedimentation-stable sols of indium (III) and tin (IV) hydroxides were obtained by Anion Resin Exchange Precipitation, which consists exchange reaction between OH ions anion resin anions metal-containing solutions. The synthesized hydrosols used to obtain conducting films In2O3 oxide doped with Tin In2O3: Sn, a surface resistance 4 kOhm/sq, thicknesses 200–500 nm transparency more ...

In in vitro tests, natural coniferous resin from the Norway spruce (Picea abies) is strongly antifungal. In this observational study, we tested the clinical effectiveness of a lacquer composed of spruce resin for topical treatment of onychomycosis. Thirty-seven patients with clinical diagnosis of onychomycosis were enrolled into the study. All patients used topical resin lacquer treatment daily...

Methods: This descriptive cross-sectional study evaluated the anatomical characteristics of the cerebellar arteries and their branches in 93 brain stem and cerebellum blocks obtained from fresh cadavers. The specimens were perfused bilaterally channeling the proximal segments of the internal carotid and vertebral arteries with a semi-synthetic resin (Palatal GP40L 85%; styrene 15%) impregnated ...

ion Ezchunye Resins-De-Acidite (The Permutit Company, New York), washed on a 40 mesh screen with distilled water, was treated several times with aqueous 4 per cent sodium carbonate and repeatedly washed with distilled water, by suspension and decantation, until the supernatant liquid was colorless and had a pH of 8.0 or less. The resin collected on a suction filter contained 70 to 80 per cent w...
