Fully bio-based and biodegradable active films based on poly(lactic acid) (PLA) blended with poly(3-hydroxybutyrate) (PHB) and incorporating lactic acid oligomers (OLA) as plasticizers and carvacrol as active agent were extruded and fully characterized in their functional properties for antimicrobial active packaging. PLA_PHB films showed good barrier to water vapor, while the resistance to oxy...

in this study, porous scaffolds from poly(d,l-lactic acid) have been prepared via liquid- liquid phase separation method in ternary system of polymer-1,4-dioxane-water. polymer dissolved in dioxane in 1.5, 2.5 and 5 % wt/v and the solvent/non-solvent ratios were 13/87, 15/85 and 17/83. cloud point curves prepared by visual turbidometry. in order to obtain porous scaffolds with inter-connected p...

lysozyme, as a model protein, was precipitated through the formation of protein-zn complex to micronize for subsequent encapsulation within poly (lactic-co-glycolic acid) (plga) microspheres. various parameters, including ph, type and concentration of added salts and protein concentration, were modified to optimize the yield of protein complexation and precipitation. the resulting protein parti...

This article reports experimental data related to the research article entitled "Poly(malic acid-co-l-lactide) as a Superb Degradation Accelerator for Poly(l-lactic acid) at Physiological Conditions" (H.T. Oyama, D. Tanishima, S. Maekawa, 2016) [1]. Hydrolytic degradation of poly(l-lactic acid) (PLLA) blends with poly(aspartic acid-co-l-lactide) (PAL) and poly(malic acid-co-l-lactide) (PML) oli...

Flexible Force Sensors In article 2202142, Terry Tao Ye, Zhaoli Gao, Jian Yang, and co-workers present the layout of skin-adhesive force sensor based on piezoelectric poly(l-Lactic acid) its potential applications in human behavior recognition, such as finger, wrist, laryngeal knot movement. The is composed photocurable acrylate films, gold electrodes film with a sandwiched structure, transpare...

The potential of neat poly(lactic acid) (PLA) and PLA/cellulose nanocrystal (CNC) blown films in extending the shelf-life crackers, a moisture-sensitive food product, was assessed. Product’s shelf-life, i.e., time required by crackers to reach its critical moisture content (CMC) 8%, determined experimentally from versus storage plots at constant temperature (25 °C) various conditions relative h...
