Critical analysis of the graphical determination of hansen's solubility parameters for lightly crosslinked polymers
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-19)
The most widely accepted method for determining Hansen's three-dimensional solubility parameters (3DSP) for crosslinked polymers entails graphically estimating the center of a spherical region in 3DSP-coordinate space whose ...
Comparison of methods of analysis of polychlorinated biphenyls in oils
(Elsevier, 1983)
In order to standardize and validate methods for the analysis of polychlorinated biphenyls in transformer oil, waste oil, hydraulic fluid and capacitor oil in the concentration range 30-500 ppm, a study was performed which ...
Optochemical Nanosensors and Subcellular Applications in Living Cells
(Springer-Verlag; Springer-Verlag Wien, 1999-06)
What may be the smallest anthropogenic devices to date, spherical sensors (wireless and fiberless) with radii as small as 10 nm have been produced. This class of optochemical PEBBLE (Probe Encapsulated By Biologically ...
Investigation of nematic liquid crystals as surface acoustic wave sensor coatings for discrimination between isomeric aromatic organic vapors
(Elsevier, 1994-04-11)
The use of thermotropic nematic liquid crystals (LC) as surface acoustic wave (SAW) vapor sensor coatings were investigated. Responses to four pairs of isomeric aromatic organic vapors were measured using two LC coatings ...
Three-dimensional solubility parameters and chemical protective clothing permeation. II. Modeling diffusion coefficients, breakthrough times, and steady-state permeation rates of organic solvents in Viton® gloves
(Wiley Subscription Services, Inc., A Wiley Company, 1993-10-15)
Three-dimensional (3-D) solubility parameters are used in separate models of the solubility, S , and diffusion coefficient, D , of organic solvents in polymers. Modeled values of these variables are then combined in ...
Fluorinated α-aminophosphonates—a new type of irreversible inhibitors of serine hydrolases
(Nauka/Interperiodica; MAIK “Nauka/Interperiodica” ; Springer Science+Business Media, 2005-01)
Improved Electrochemical Analysis of Neuropathy Target Esterase Activity by a Tyrosinase Carbon Paste Electrode Modified by 1-Methoxyphenazine Methosulfate
(Kluwer Academic Publishers; Springer, 2005-08)
A graphite-paste tyrosinase biosensor was improved by adding 1-methoxyphenazine methosulfate as a mediator. Mediator modification enhanced sensitivity to phenol 4-fold and long-term stability 3-fold. Phenol could be detected ...
Improved methods for the determination of hansen's solubility parameters and the estimation of solvent uptake for lightly crosslinked polymers
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-19)
Two new methods for determining Hansen's three-dimensional solubility parameters (3DSP) for lightly crosslinked polymers are presented and evaluated using commercial glove materials composed of butyl, natural, nitrile, and ...
Comparison of methods for particulate phase mercury analysis: sampling and analysis
(Springer-Verlag, 2002-11)
Accurate and reliable sampling and analysis of mercury forms is an overriding aim of any atmospheric monitoring effort which seeks to understand the fate and transport of the metal in the environment. Although a fraction ...
