Influence of Culture Conditions on Poly-3-Hydroxybutyrate Production by a Newly Isolated Bacillus cereus Y23
(Wiley VCH Verlag, 2020-04)
Polyhydroxyalkanoates (PHAs), environmental friendly polyesters, can be produced by a wide range of microorganisms in nutrient-limiting conditions. In the present study a new bacterial strain, able to produce high quantities ...
Bioconversion of glycerol into polyhydroxyalkanoates by a salt-tolerant indigenous strain, Halomonas titanicae KHS3
(Biocell, 2018)
Halomonas titanicae KHS3 was isolated from hydrocarbon-contaminated water in Mar del Plata harbor. This strain is able to accumulate polyhydroxyalkanoates (PHAs), reserve polymers that can be used as raw material for the ...
Study of the lamellar and micellar phases of pluronic F127: A molecular dynamics approach
(Multidisciplinary Digital Publishing Institute, 2019-09-07)
In this work, we analyzed the behavior of Pluronic F127 through molecular dynamics simulations at the coarse-grain level, focusing on the micellar and lamellar phases. To this aim, two initial polymer conformations were ...
Waterborne acrylic-melamine latexes with controlled film microstructure
(Elsevier Science Sa, 2019-11)
Crosslinkable latexes aim to improve the physical properties of coalesced latex films, over levels attainable with thermoplastic latexes, which lackthermal, mechanical and solvent resistance. This work investigated the ...
Transport and Spectroscopy in Conjugated Molecules: Two Properties and a Single Rationale
(American Chemical Society, 2020-05)
In the context of electron dynamics simulations, when the charge density of a molecule is subject to a perturbation in the form of a short electric field pulse, density fluctuations develop in time. In the absence of ...
Fossil cutin of Johnstonia coriacea (Corystospermaceae, Upper Triassic, Cacheuta, Argentina)
(Elsevier Science, 2018-03)
For the first time, a cutin polymer was obtained from specimens of Johnstonia coriacea (Corystospermales, Corystospermaceae) from the Upper Triassic of Cacheuta, Argentina. These are preserved as fossilized cuticles i.e., ...
Food Biopackaging Based on Chitosan
(Springer, 2018)
Chitin, available from waste products of the shellfish industry (shells of the crab, shrimp, etc), is one of the most abundant natural polymers in world and it is used for the production of chitosan by deacetylation. Chitosan, ...
Crosslinkable acrylic-melamine latex produced by miniemulsion polymerization
(Elsevier Science Sa, 2018-05)
Nowadays, crosslinkable polymers are highly demanded in applications where improved thermal, mechanical, and chemical strengths are required. Among crosslinkable polymers, those with film forming capability (e.g., coatings ...
Effect of the potential on the electrochemically induced ageing of polyaniline films
(Elsevier Science Sa, 2012-03)
The electrochemically induced ageing of polyaniline films, as a function of the ageing potential, was investigated employing films of different thicknesses in 3.7 M H2SO4 solutions. The ageing process was monitored by the ...
PLGA based drug delivery systems (DDS) for the sustained release of insulin: Insight into the protein/polyester interactions and the insulin release behavior
(John Wiley & Sons Ltd, 2010-12)
BACKGROUND: Drug delivery systems (DDS) were designed using insulin as model drug and poly (lactic-co-glycolic) copolymers (PLGA) as polymeric matrix. The carriers were synthesized by direct self-assembly of the insulin ...
