Investigation of the effects of orientation on freeze/thawed Polyvinyl alcohol hydrogel properties.
(Elsevier, 2018-12)
Although hydrogels produced via freeze-thawing (F/T) technique have been thoroughly studied in literature, stretching hydrogels in between freeze-thawing cycles could change its properties and might be modulated for drug ...
Characteristics of the treated calcium carbonate particles with stearic acid using different treating methods.
(Elsevier, 2016-08)
Calcium carbonate (CaCO3) is often treated with stearic acid (SA) to decrease its polarity. However, the method of application of the SA treatments has a strong influence on their interface structure and distribution. ...
Titanium-Niobium (Ti-xNb) alloys with high Nb amounts for applications in biomaterials
(Scielo, 2020-11-10)
The present study produced binary titanium-niobium alloys Ti-xNb with high niobium percentage
(x = 50, 80 e 90 wt.%) aiming to apply it as a base material in osseous implant devices. The produced
TiNb alloys presented a ...
Investigation of a novel freeze-thaw process for the production of drug delivery hydrogels
(Springer, 2005-12)
Poly(vinyl alcohol) (PVA) is a water-soluble, biocompatible and biodegradable polymer, which has been widely applied in biomedical fields. In this paper, novel physically cross-linked hydrogels composed of PVA and comprising ...
Electrospun hydrogels composites for bone tissue engineering.
(Woodhead Publishing, 2019)
Electrospinning is one of the foremost nanotechnology applications to fabricate bone tissue engineering scaffolds with sizes in the nanometer range. It is regarded as a versatile, inexpensive, and relatively simple methodology ...
On the possibility of replacement of calcium carbonate by a high-performance, economically viable filler in polyethylene composites
(Sage, 2021-07-14)
Calcium carbonate (CaCO3) is frequently added to polyethylene (PE) as a filler to reduce costs. An alternative to CaCO3, calcium fluoride (CaF2) was proposed in this research. PE/CaCO3 and PE/CaF2 composites in a wide ...
Polymer based additive manufacturing historical developments, process types and material considerations.
(Springer Nature, 2019)
3D printing is a manufacturing technique where parts are built in a layer-by-layer fashion. The earliest embodiments were based on generating successive layers of solidified materials at the air liquid interface through ...
A bilayer vaginal tablet for the localized delivery of disulfiram and 5-fluorouracil to the cervix
(MDPI, 2020-12-06)
This study was performed to develop an adjuvant therapy in the form of a self-administered
vaginal tablet regimen for the localized delivery of chemotherapeutic drugs. This therapy will help to
reduce relapse by eradicating ...
Durum wheat seed germination response to hydrogel coatings and moisture under drought stress.
(Science Publications, 2016-11)
Abstract: Technologies that can increase crop production while
maintaining low pollution are essential for sustainable agriculture. This
study compares the germination performance of Durum wheat seeds
(Triticum durum ...
Synthesis and characterisation of novel n-vinyl pyrrolidinone/acrylic acid copolymers for use in biomedical applications.
(2006)
The aim of this study was to develop a novel hydrophilic polymer for use in biomedical applications. The polymers synthesised in this work were based on the monomers N-vinyl pyrrolidinone (NVP) and acrylic acid (AA) and ...
