چکیده
The aim of this work is to explore the manufacturing insulation structures using fused filament deposition biosourced materials. approach considers printing Polylactic acid (PLA) and PLA-flax (PF) varied infill density temperatures. Differential Scanning Calorimetry Thermal Gravimetry analysis are performed study thermal behaviour PLA PF derive weight content fibres within PF. measurements show a strong dependence conductivity with slightly improved compared PLA. Moreover, both hydrophobic unlike conventional green concretes based on hemp or flax. In addition, scanning electron optical microscopies marked morphological changes induced by laying down process for This latter exhibits more complex tortuous microstructure presence inter-filament porosity. concludes superior hygrothermal properties other materials such as flax concrete. also beneficial role that provides better printed well need optimize characteristics including cell morphology density.

PLA-based regular structures and their synthesis
Two regular circuit structures based on the programmable logic array (PLA) are proposed. They provide alternatives to the widely used standard-cell structure and have better predictability and simpler design methodologies. A whirlpool PLA is a cyclic four-level structure, which has a compact layout. Doppio-ESPRESSO, a four-level logic minimization algorithm, is developed for the synthesis of Wh...
متن کاملMicro- to nanoscale structure of biocompatible PLA-PEO-PLA hydrogels.
We 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 hydrogels showed power law scattering in the USAS regime, which is indicative of scatteri...
متن کاملEffect of different mass ratio of PLA: PEG segments in PLA-PEG-PLA copolymers on the physicochemical characterization and DNA release profile
Background: Adapting controlled release technologies to the delivery of DNA has the great potential to overcome extracellular barriers that limit gene delivery. This study investigates the effect of different mass ratio of PLA: PEG in the various tri block poly (lactic acid)-poly (ethylene glycol) - Poly (lactic acid) copolymer (PLA-PEG-PLA) on the properties of the resulting nanoparticles. Me...
متن کاملInvestigation of membrane protein-protein interactions using correlative FRET-PLA.
Fluorescence resonance energy transfer (FRET) analysis and the recently developed proximity ligation assay (PLA) are widely used to study protein-protein interactions in situ. We have developed correlative FRET-PLA to monitor interactions between membrane proteins that frequently cause problems in confirmatory co-immunoprecipitation assays. Correlative FRET-PLA is particularly aimed at deliveri...
