Intranasal delivery of zidovudine by PLA and PLA–PEG blend nanoparticles
International Journal of Pharmaceutics, 2010This study describes the preparation and evaluation of biodegradable poly(l-lactide) (PLA) and poly(l-lactide)-poly(ethylene glycol) (PLA-PEG) blend nanoparticles containing zidovudine as model drug. The prepared nanoparticles were characterized in terms of size, zeta potential, morphology and drug entrapment efficiency.

A continuous RESS process to prepare PLA–PEG–PLA microparticles
The Journal of Supercritical Fluids, 2011Abstract A continuous RESS (rapid expansion of supercritical solution) process that combines an SEDS (solution enhanced dispersion by supercritical fluids) process and RESS process was developed to prepare the microparticles of polylactide–poly(ethylene glycol)–polylactide (PLA–PEG–PLA) triblock copolymer.

PLA–PEO–PLA Hydrogels and Their Mechanical Properties
2011Poly(lactide) – block – poly(ethylene oxide) – block – poly(lactide) [PLA–PEO–PLA] triblock copolymers are known to form physical hydrogels in water, due to the polymer’s amphiphilic architecture. Their biodegradability has made them attractive for use as soft tissue scaffolds and other biological applications such as drug delivery.

Journal of environmental polymer degradation, 1997
Polylactic acid (PLA) is a hydrolytically degradable aliphatic polyester, and water vapor permeability may have a significant influence on the rate of degradation. A method is devised to use bags prepared from PLA films and filled with molecular sieves to determine the water vapor permeability in the polymer, its copolymers with caprolactone, and ...

Proceedings of the 39th conference on Design automation - DAC '02, 2002
A regular circuit structure called a River PLA and its re-configurable version, Glacier PLA, are presented. River PLAs provide greater regularity than circuits implemented with standard-cells. Conventional optimization stages such as technology mapping, placement and routing are eliminated.

FIRE BEHAVIOUR OF 3D PRINTED PLA AND WOOD/PLA COMPOSITES
2019Additive manufacturing technologies have achieved great development in last decade on area of technology and printing materials. Special emphasis is placed on the development of materials that would be cheaper, from natural sources, without releases of harmful substances during the manufacturing process and usage, with the possibility of using waste ...

PLA widely used in many fields has gained enormous attention because of its biodegradable and biocompatible properties. However, unitary structure and poor properties of PLA such as the inherent brittleness, poor melt strength, low heat deflection temperature (HDT), narrow processing window and low thermal stability have posed considerable scientific ...
