Development of a disposable electrode modified with carbonized, graphene‐loaded nanofiber for the detection of dopamine in human serum
(HanserWiley Periodicals, Inc., 2014-10-05)
A one‐step electrode surface modification is proposed in which a disposable, screen‐printed carbon electrode is functionalized with carbonized, electrospun polyacrylonitrile (PAN)‐loaded graphene (G) nanoparticles to form ...
Multiple scattering in small-angle neutron scattering measurements on polymers
(Elsevier, 1983-02)
Multiple scattering corrections in small-angle neutron scattering experiments on polymers have been examined. Numerical calculations show that, for typical experimental conditions, the second-order scattering is less than ...
Concentration dependence of diffusion coefficient at various molecular weights and temperatures
(Elsevier, 1981-09)
The effect of temperature on the concentration dependence of the diffusion coefficient D(c) is investigated experimentally by light scattering using polystyrene with Mw = 179 000 and 900 000 in toluene and cyclohexane at ...
Superposition of small shear deformations on large uniaxial extensions for viscoelastic materials
(Elsevier, 1985-07)
The equation for small amplitude torsional response superposed on a finite axial stretch history is derived for a material modelled by the BKZ constitutive equation. For the case of a uniaxial step stretch history, this ...
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 ...
Structural and mechanical behavior of layered zirconium phosphonate as a distributed phase in polycaprolactone
(Wiley Subscription Services, Inc., A Wiley Company, 2009-10-15)
Mixed-surface octyl/methoxyundecyl Α-zirconium phosphonates (ZrPs) were investigated as distributed nanoscale fillers, in concentrations up to 50% w/w, for the purpose of increasing the elastic modulus and yield strength ...
Ultrasonic measurements of the elastic moduli of liquid crystalline polymers
(Elsevier, 1992)
The five independent elastic moduli of extruded rods of two thermotropic liquid crystalline polymers, Vectra B900 and Vectra A950, and the nine independent moduli of an injection-moulded bar of Vectra A950 have been measured ...
Capillary liquid chromatography fraction collection and postcolumn reaction using segmented flow microfluidics
(Wiley Periodicals, Inc., 2013-11)
The preparation and morphology of PPO–epoxy blends
(Wiley Subscription Services, Inc., A Wiley Company, 1993-05-10)
Poly(phenylene oxide) (PPO) was found to be miscible in diglycidyl ether of bisphenol A (DGEBA) based epoxy. The PPO–DGEBA system exhibited upper critical solution temperature (UCST) behavior. The cloud point temperatures ...
Orthogonal surface functionalization through bioactive vapor‐based polymer coatings
(Academic PressWiley Periodicals, Inc., 2014-07-15)
Reactive chemical vapor deposition (CVD) polymerization provides a substrate‐independent platform for effective functionalization of virtually any solid substrates, flat, or curved, even with complex geometries. This article ...
