A biophysically based multilayer continuum model of the facial soft tissue composite has been developed for simulating wrinkle formation. The deformed state of the soft tissue block was determined by solving large deformation mechanics equations using the Galerkin finite element method. The proposed soft tissue model is composed of four layers with distinct mechanical properties. These include ...
Most gas barrier films produce cracks that lead to a significant loss of integrity when strain is applied. In order fabricate stretchable with low water permeability and high endurance after stretching, we used polydiallydimethylammonium (PDDA) mixed graphene oxide (GO) poly (vinyl alcohol) (PVA) montmorillonite (MMT). These were manufactured by layer-by-layer assembly on an Ecoflex/polydimethy...
A novel SPES-NH(2)-GA-Nafion® composite membrane with higher proton conductivity and lower methanol permeability was fabricated by covalent crosslinking layer-by-layer self-assembly of an unbalanced charged polyampholyte (SPES-NH(2)) and glutaraldehyde (GA) with controllable free sulfonic acid content.
We developed quantum dot-engineered M13 virus layer-by-layer hybrid composite films with incorporated fluorescence quenchers. TNT is designed to displace the quenchers and turn on the quantum dot fluorescence. TNT was detected at the sub ppb level with a high selectivity.
Consecutive grafting of crosslinked L-phenylalanine anilide, D-phenylalanine anilide and non-imprinted polymer layers on the surface of wide pore silica resulted in porous composite beads displaying enantiomeric discrimination reflecting the last grafted layer. This no longer holds for beads freed from silica, which instead display enantioselectivity reflecting the first grafted layer.
This paper reports the isolation of individual layers in a thin composite reverse osmosis membrane. Unlike previous studies where the active layer has always been isolated on top of a solid support, we were able to obtain layers of unsupported active layer. These layers were characterised for their thickness, water vapour sorption and salt transport properties.
