Polymeric Scaffolds in Tissue Engineering Application: A Review
Tập 2011 - Trang 1-19 - 2011
Current strategies of regenerative medicine are focused on the restoration of
pathologically altered tissue architectures by transplantation of cells in
combination with supportive scaffolds and biomolecules. In recent years,
considerable interest has been given to biologically active scaffolds which are
based on similar analogs of the extracellular matrix that have induced synthesis
of tissues an...
Chemical Recycling of PET Wastes with Different Catalysts
Tập 2015 - Trang 1-11 - 2015
Chemical recycling of polyethylene terephthalate, known as PET, has been the
subject of increased interest as a valuable feedstock for different chemical
processes. In this work, glycolysis of PET waste granules was carried out using
excess ethylene glycol in the presence of different simple chemicals acting as
catalysts, which are, namely, categorized in ionic liquids, metal salts,
hydrotalcites,...
Polylactic Acid Based Nanocomposites: Promising Safe and Biodegradable Materials in Biomedical Field
Tập 2016 - Trang 1-11 - 2016
Polylactic acid (PLA) is widely used in biological areas due to its excellent
compatibility, bioabsorbability, and degradation behavior in human bodies. Pure
polylactic acid has difficulty in meeting all the requirements that specific
field may demand. Therefore, PLA based nanocomposites are extensively
investigated over the past few decades. PLA based nanocomposites include PLA
based copolymers i...
PBAT/TPS Composite Films Reinforced with Starch Nanoparticles Produced by Ultrasound
Tập 2017 - Trang 1-10 - 2017
The objective of the present work was to study the incorporation of starch
nanoparticles (SNP) produced by ultrasound in blends of poly(butylene
adipate-co-terephthalate) (PBAT) and thermoplastic starch (TPS). The films were
produced by extrusion using varying percentages of SNP (1, 2, 3, 4, and 5% w/w).
The SNP were prepared in water without the addition of any chemical reagent. The
results revea...
Investigation of Optimum Polymerization Conditions for Synthesis of Cross-Linked Polyacrylamide-Amphoteric Surfmer Nanocomposites for Polymer Flooding in Sandstone Reservoirs
Tập 2015 - Trang 1-14 - 2015
Currently enhanced oil recovery (EOR) technology is getting more attention by
many countries since energy crises are getting worse and frightening. Polymer
flooding by hydrophobically associated polyacrylamides (HAPAM) and its modified
silica nanocomposite are a widely implemented technique through enhanced oil
recovery (EOR) technology. This polymers class can be synthesized by
copolymerization o...
Mechanical Properties of Steel-FRP Composite Bars under Tensile and Compressive Loading
Tập 2017 - Trang 1-11 - 2017
The factory-produced steel-fiber reinforced polymer composite bar (SFCB) is a
new kind of reinforcement for concrete structures. The manufacturing technology
of SFCB is presented based on a large number of handmade specimens. The
calculated stress-strain curves of ordinary steel bar and SFCB under repeated
tensile loading agree well with the corresponding experimental results. The
energy-dissipati...
Biosynthesis of Xanthan Gum from Fermenting Shrimp Shell: Yield and Apparent Viscosity
Tập 2014 - Trang 1-8 - 2014
With the aim of producing xanthan gum, the effects of an aqueous shrimp shell
extract (SSAE) as the source of carbon and nitrogen on the yield and apparent
viscosity of the gums produced by fermentation using three native strains
ofXanthomonas campestriswere studied. It was found that the SSAE contained
89.75% moisture, 0.054% ash, 8.069% protein, 0.787 lipids, and 1.337%
carbohydrates. Media cont...
Eco-Friendly Approach and Potential Biodegradable Polymer Matrix for WPC Composite Materials in Outdoor Application
Tập 2019 - Trang 1-9 - 2019
Blends based on high-density polyethylene (HDPE) and poly(lactic) acid (PLA)
with different ratios of both polymers were produced: a blend with equal amounts
of HDPE and PLA, hence 50 wt.% each, proved to be a useful compromise, allowing
a high amount of bioderived charge without this being too detrimental for
mechanical properties and considering its possibility to biodegradation
behaviour in out...
Preparation and Structural Properties of Free Films from Rapeseed Oil-Based Rigid Polyurethane-Montmorillonite Nanocomposites
Tập 2013 - Trang 1-8 - 2013
The preparation of free standing films of biobased rigid polyurethanes (PU) from
rapeseed oil (RO) and diethanolamine (DEA) polyol and its modification with
organomontmorillonite (OMMT) nanoparticles are described. Heat enthalpy of the
interaction duringin situmixing of RO/DEA polyol and OMMT is measured in
isothermal profile. The Fourier transform infrared spectral analysis (FTIR-ATR)
is used to ...
Effect of Particle Size of Additives on the Flammability and Mechanical Properties of Intumescent Flame Retarded Polypropylene Compounds
Tập 2015 - Trang 1-7 - 2015
The effect of particle size reduction of the components of a common intumescent
flame retardant system, consisting of pentaerythritol (PER) and ammonium
polyphosphate (APP) in a weight ratio of 1 to 2, was investigated on the
flammability and mechanical performance of flame retarded polypropylene (PP)
compounds. Additives of reduced particle size were obtained by ball milling. In
the case of PER, ...
