Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

open access: yesAdvanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

Exact Results for Kinetics of Catalytic Reactions

open access: yes, 1995
The kinetics of an irreversible catalytic reaction on substrate of arbitrary dimension is examined. In the limit of infinitesimal reaction rate (reaction-controlled limit), we solve the dimer-dimer surface reaction model (or voter model) exactly in ...

Shear‐Induced Nematic Alignment in Polysulfone Melts

open access: yesAdvanced Functional Materials, EarlyView.
Shear‐induced alignment is investigated by means of rheology and birefringence on an amorphous linear polysulfone melt. The absence of crystallization makes PSU particularly enabling to investigate temperature effects on the shear‐alignment of linear polymers, unveiling the role of chain relaxation times and possible enthalpic contributions.

Investigation of the Degree of Monomer Conversion in Dental Composites through Various Methods: An In Vitro Study

open access: yesApplied Sciences
The degree of monomer conversion (DC) values of three different dental composites were examined using three different methods: surface microhardness (ratio of bottom/top), Fourier-transform infrared (FT-IR), and differential scanning calorimetry (DSC ...
