Micro- to Nanoscale Structure of Biocompatible PLA−PEO−PLA Hydrogels
Langmuir, 2007We observe large-scale structures in hydrogels of poly(l-lactide)-poly(ethylene oxide)-poly(l-lactide) (PLLA-PEO-PLLA) ranging in size from a few hundred nanometers to several micrometers. These structures are apparent through both ultra-small angle scattering (USAS) techniques and confocal microscopy.

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1991
A fault model for programmable logic arrays (PLAs) is discussed that handles four classes of faults: multiple stuck-at faults, multiple bridging faults, multiple crosspoint faults, and faults due to breaks in lines. It is shown that a test that detects all multiple crosspoint faults also detects all multiple stuck-at faults, multiple bridging faults ...

Development of nanocellulose-reinforced PLA nanocomposite by using maleated PLA (PLA-g-MA)
Journal of Thermoplastic Composite Materials, 2017The goal of this research was improving the mechanical and physical properties of poly lactic acid (PLA) using cellulose nanofiber (CNF) as reinforcing and maleated PLA (PLA-g-MA) as a compatibilizer. PLA/nanocellulose composites were prepared through melt mixing with maleated PLA (5 wt%) and two levels of cellulose nanofibers (CNFs) (3 and 5 wt ...

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.

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 ...
