The hierarchical porous structures of vinyl polymers, such as polystyrene (PSt) and poly(methyl methacrylate) (PMMA), were derived from morphologies of a biomineral through replication. The resultant PSt hierarchical structures showed enhanced adsorption properties of organic molecules as hydrophobic adsorbents in an aqueous medium.

It was shown how high mechanical strength should be provided in the high numerical aperture (NA) graded-index plastic optical fiber (GI POF). In this newly developed GI POF, a copolymer of methyl methacrylate (MMA) and 2,2,2-trifluoroethyl methacrylate (3FMA) was used to increase the NA. The GI POF we proposed previously was composed of a PMMA homopolymer cladding and a doped PMMA core. It was ...

Purpose: The goal of this investigation was to characterize the compliance properties in selected polymers used for temporary (provisional crown and bridge) applications. Method: Polymethyl methacrylate (PMMA)- and polyethyl methacrylate (PEMA)-based JET and TRIM II were investigated along with two bisacryl composite resins (LUXATEMP and PROTEMP 3 GARANT). Rectangular samples of the resins were...

Utilization of computer-aided design/computer-aided manufacturing (CAD/CAM) increases in dental prosthetics. From single restorations and bridges, computer-aided engineering supports fabrication of partial and now complete removable dentures. Improved materials, like crosslinked poly (methyl methacrylate) (PMMA) and CAD/CAM technology permit realization of a superior quality denture in shorter ...

A gallium phosphide (GaP) photovoltaic junction is grown by molecular beam epitaxy (MBE) on a GaP substrate. An anti-reflection coating of polymethyl methacrylate (PMMA) is applied and the cell is measured under concentrations of 1 and 10.7 in an outdoor setting. Efficiencies up to 2.6% and open circuit voltages up to 1.57 V are reported. & 2011 Elsevier B.V. All rights reserved.

Thin planar polymer films are model systems in a number of fields, including nanoand biotechnology. In contrast to reciprocal space techniques such as reflectivity or diffraction, secondary ion mass spectrometry SIMS can provide depth profiles of tracer labeled polymers in real space directly with sufficient depth resolution to characterize many important aspects in these systems. Yet, continue...

Adhesion of coagulase-negative staphylococci (CNS) was studied onto a homologous series of methacrylate polymers and copolymers. The materials varied in wettability (contact angles) and were either positively or negatively charged (zeta-potential). Bacterial adhesion experiments performed in a parallel-plate perfusion system showed that positively charged TMAEMA-Cl copolymers significantly prom...

The physicochemical properties of polymers can be modified by spatial configuration. Here, dielectric spectroscopy (DS) was employed to investigate the effect tacticity on glass-transition dynamics confined polymer films. We have also carried out relaxation studies at ambient and elevated pressure conditions. High-pressure measurements provide information sensitivity density changes, which help...
