Mixed brush of chemically and physically adsorbed polymers under shear: Inverse transport of the physisorbed species
(American Institute of Physics, 2014-01)
We study mixed brushes under shear flow by molecular dynamics simulation with an explicit solvent. The primary brush is formed by chemically grafting polymers to a solid substrate, the secondary brush is comprised of ...
Effects of short-term immersion and brushing with different denture cleansers on the roughness, hardness, and color of two types of acrylic resin
(2015-01-01)
Purpose: To investigate the cumulative effects of brushing (B) or immersion (I), using different cleansing agents, on the surface roughness, hardness and color stability of a heat-polymerized denture resin, Lucitone 550 ...
Surface roughness and color change of a composite: Influence of beverages and brushing
(JAPANESE SOC DENTAL MATERIALS DEVICESTOKYO, 2012)
This study evaluated the influence of beverages and brushing on the surface roughness(SR) and color change(Delta E) of a composite resin. For this, 120-disks(10 mmx2 mm) of composite resin(Filtek-Z250) were prepared and ...
Electrochemical studies based on local interfacial ph changes of gold nanoparticles immobilized on polystyrene brushes
(2013-03-01)
The electrochemical behavior of polystyrene modified with gold nanoparticle (Au NPs) was investigated in terms of pH-responsive polymer brush. A pH-responsive of modified polymer brush from tethered polystyrene was prepared ...

Polymer Brushes Here, There and Everywhere: Recent Advances in Their Practical Applications and Emerging Opportunities in Multiple Research Fields
(Wiley, 2012-03)
Bottom-up surface processing with well-defined polymeric structures becomes increasingly important in many current technologies. Polymer brushes, that is, assemblies of macromolecules tethered at one end to a substrate, ...
Detecting Image Brush Editing Using the Discarded Coefficients and Intentions
This paper describes a quick and simple method to detect brush editing in JPEG images. The novelty of the proposed method is based on detecting the discarded coefficients during the quantization of the image. Another novelty ...
Polymer Brush Modified Electrode with Switchable Selectivity Triggered by pH Changes Enhanced by Gold Nanoparticles
(Destech Publications, Inc, 2014-01-01)
In this work a pH sensor was build up with smart material based on polymer brush and gold nanoparticles. The modified electrode functionalized with a polymer brush Polyacrylic Acid (PAA) tethered to the surface and covered ...
Effect of microwave disinfection on the surface roughness of three denture base resins after tooth brushing
(Wiley-Blackwell, 2011-12-01)
Objective: This study investigated the effect of microwave disinfection on the roughness of three heat-polymerised acrylic resins after tooth brushing. Background: Microwave disinfection has been recommended to reduce ...
