Composite and bi-layer films based on gelatin and chitosan
(Elsevier, 2009-02)
The aims of this work were: to develop composite, bi-layer and laminated biodegradable films based on gelatin and chitosan, to determine film barrier and mechanical properties and to characterize their microstructure. ...
Synergetic effect of silver nanoparticles and thiram on lipid bilayers
(2022-02-15)
The excessive concentration of nanomaterials and pesticides in industrial products, food, and in the environment can be a risk to human health. Exposure to these materials can occur through inhalation, dermal contact, or ...
Improved prediction of bilayer and monolayer properties using a refined BMW-MARTINI force field
(Elsevier Science, 2016-08-31)
Coarse-grained (CG) models allow enlarging the size and time scales that are reachable by atomistic molecular dynamics simulations. A CG force field (FF) for lipids and amino acids that possesses a polarizable water model ...
Mechanical properties of bilayers containing sperm sphingomyelins and ceramides with very long-chain polyunsaturated fatty acids
(Elsevier Ireland, 2019-01)
Sphingomyelins (SM) and ceramides (Cer) with very long chain polyunsaturated fatty acids (V) are important components of spermatozoa membranes. In this study, the mechanical properties of bilayers of SM and Cer with ...
One-Photon Lithography for High-Quality Lipid Bilayer Micropatterns
(American Chemical Society, 2015-10)
A relevant question in cell biology with broad implications in biomedicine is how the organization and dynamics of interacting membranes modulate signaling cascades that involve cell-cell contact. The functionalization of ...
Nanocomposite bilayers based on poly(vinyl alcohol) and chitosan functionalized with gallic acid
(Elsevier Science, 2020-03)
The development of active bilayer systems is a novel strategy for the application of active packaging to maintain or prolong the shelf‐life of food products. A bilayer system was assembled in situ into a thermocompression ...
Quantum phase transitions into Kondo states in bilayer graphene
(American Physical Society, 2014-02)
We study a magnetic impurity intercalated in bilayer graphene. A representative configuration generates a hybridization function with strong dependence on the conduction-electron energy, including a full gap with one hard ...
Soy protein – Poly (lactic acid) bilayer films as biodegradable material for active food packaging
(Elsevier, 2013-12)
The preparation and characterization of biodegradable bilayer films from isolated soy protein (SPI) and poly (lactic acid) (PLA) were carried out in this work. The films showed high transparency and strong adhesion between ...
