Oriented polymeric sheets exhibiting dichroism and articles containing the same.
(2007-12-20)
Provided is an oriented polymeric sheet comprising a photochromic-dichroic material, wherein the sheet exhibits dichroism in an activated state. Also provided is a multilayer composite comprising at least a support layer ...
Synthesis of linear aliphatic polycarbonate macroglycols using dimethylcarbonate.
(Wiley, 2009-01-05)
A series of linear aliphatic polycarbonate polyols were synthesized using dimethylcarbonate and a linear alkane diol or specific combinations of linear alkane diols. Polyol synthesis was carried out in a two‐stage process ...
Review of multifarious applications of Poly (lactic acid)
(Taylor & Francis, 2016)
Poly (lactic acid) is considered to be a promising alternative to petroleum-based polymers due to its renewability, biodegradability, biocompatibility, and good mechanical properties. Because of the high cost, the applications ...
Analysis of the mechanical properties of solvent cast blends of PLA/PCL.
(Trans Tech Publications, 2014-09)
Polylactic acid (PLA) is the most promising material in the biodegradable category. However, brittleness and poor thermal stability restrict its application. To overcome this limitation, PLA may be blended with other ...
Micro-injection moulding of poly(vinylpyrrolidone-vinyl acetate) binary and ternary amorphous solid dispersions.
(MDPI, 2019-05)
Micro-injection moulding (µIM) was used for the production of enteric tablets of plasticised
and unplasticised solid dispersions of poly(vinylpyrrolidone-vinyl acetate) (PVPVA), and the effect
of the mechanical and thermal ...
Development of multifunctional hydrogels for the delivery of drugs and nutrients for patients with inflammatory bowel disease
(Athlone Institute of Technology, 2020-06)
Inflammatory Bowel Disease (IBD) is a group of diseases that affect the gastrointestinal tract (GI). Comprised of Crohn’s Disease (CD) and Ulcerative Colitis (UC), it affects 6.8 million people globally. IBD is characterised ...
Investigation of ethylene oxide-co-propylene oxide for dissolution enhancement of hot-melt extruded solid dispersions.
(Elsevier, 2018-02)
The optimal design of amorphous solid dispersion (ASD) formulations requires the use of excipients to maintain supersaturation and improve physical stability in order to ensure shelf-life stability and better absorption ...
Investigation of miscibility estimation methods between indomethacin and poly(vinylpyrrolidone-co-vinyl acetate).
(Elsevier, 2018)
The investigation of the miscibility between active pharmaceutical ingredients (API’s) and polymeric excipients is of great interest for the formulation and development of amorphous solid dispersions, especially in the ...
Reinforced polylactic acid for use in high strength biodegradable medical implants.
(2016)
Traditional medical implants, such as orthopedic screws, pins, and
coronary stents, are almost exclusively metallic due to high mechanical
strength requirements. However, issues related to the use of permanent
metallic ...
Stability studies of hot-melt extruded ternary solid dispersions of poorly-water soluble Indomethacin with Poly(vinyl pyrrolidone-co-vinyl acetate) and polyethylene oxide.
(Elsevier, 2019-08)
This investigation aims to evaluate the effect of moisture and temperature on the physical
stability and dissolution behaviour of hot-melt extruded binary and plasticised ternary solid
dispersions. Poorly water-soluble ...
