Effect of Chemical Treatments and HDPE-g-MA on the physical and mechanical behaviour of HDPE/ natural fibre composites.
(2013)
Many authors have reported on the use of natural fibres (raw or chemically modified) as
reinforcing elements for high density polyethylene (HDPE). These materials have generated a lot of
interest due to their low cost ...
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 ...
Processing stability and the significance of variation in extrusion speeds and temperture on SSB® 55 Pharma Grade Shellac for Oral Drug Delivery
(MDPI, 2017-09-06)
The melt-extrusion process is utilized in the pharmaceutical arena for the manufacturing of a variety of dosage forms and formulations, including solid dispersions. This technology is considered an efficient and continuous ...
Development of a multi-layered vaginal tablet containing Dapivirine, Levonorgestrel and Acyclovir for use as a multipurpose prevention technology.
(Elsevier, 2016-07)
Multipurpose prevention technologies (MPTs) are preferably single dosage forms
designed to simultaneously address multiple sexual and reproductive health needs,
such as unintended pregnancy, HIV infection and other ...
Material considerations for fused-filament fabrication of solid dosage forms.
(MDPI, 2018-04-02)
Material choice is a fundamental consideration when it comes to designing a solid dosage form. The matrix material will ultimately determine the rate of drug release since the physical properties (solubility, viscosity, ...
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. ...
Freeze-thaw electrospun PVA-Dacarbazine nanoparticles: preparation, characterization and anticancer evalution.
(Taylor & Francis Online, 2019-06-13)
Dacarbazine (DTIC) is an antitumor agent that has limited clinical applications due to its insolubility, instability and toxicity to normal cells. One possibility to achieve controlled release is PVA-based NPs. This work ...
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 ...
An investigation of the inter-molecular interaction, solid-state properties and dissolution properties of mixed Copovidone hot-melt extruded solid dispersions.
(Elsevier, 2019-10)
Previous research has focused on spray dried quaternary mixtures which due to the addition of a surfactant 26 affected the physical stability and amorphous stability of selected model drugs. Very little research has 27 ...
Development of synthetic alternatives for bone tissue engineering.
(Australian Journal of Basic and Applied Sciences, 2013)
Due to the inherent limitations of current biological bone grafts, alternative synthetic
substitutes are being pursued. Therefore, this study aimed to improve the bioactive and compressive
properties of photopolymerisable ...
