Microwave Characterization of 3D Printed PLA and PLA/CNT Composites
2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI), 2021The aim of this paper is to characterize dielectric properties of polylactic acid, one of the most commonly used materials for 3D-printing, at microwave frequencies, specifically at X-band. The knowledge of the complex permittivity of this plastic material is important for many applications. The manufacturing process of the printed object also requires

New properties from PLA–PEO–PLA hydrogels
Soft Matter, 2005Polymeric materials are important in many medical applications. Regenerative medicine offers the potential to repair or replace damaged tissue and polymers are an essential component of many tissue engineering approaches. Hydrogels have many advantageous properties but, generally, lack robust mechanical properties.

Method of PLA's Implementation : The Monoplane PLA
ESSCIRC '85: 11th European Solid-State Circuits Conference, 1985This paper presents several techniques for optimizing large monoplane PLAs (which contain mixed I/O lines). The different approaches used to optimize the area of these PLAs involve several VLSI topological optimization strategies. Compaction by cutting and reorganizing the product-term lines in order to reduce the number of rows in the entire PLA, is ...

PLA-Coated Gold Nanoparticles for the Labeling of PLA Biocarriers
Chemistry of Materials, 2004Poly-dl-lactide end-capped by a protected thiol was synthesized by bulk ring-opening polymerization (ROP) of dl-lactide initiated by the reaction product of aluminum isopropoxide [Al (iOPr) 3] with α- (2,4-dinitrophenylsulfenyl) ethanol. After the thiol deprotection, PLA-SH was used to stabilize gold nanoparticles.

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.

The FHDL (Florida Hardware Design Language) PLA tools provide a means for specifying, simulating, and automatically laying out Programmed Logic Arrays (PLAs). These tools were created to facilitate VLSI design projects, to improve the quality of hardware design courses, and to serve as a basis for future research in VLSI design automation.

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 ...
