Recovery of spent coffee grounds oil using supercritical CO2: Extraction optimisation and physicochemical properties of oil

open access: yesCyTA - Journal of Food, 2019
Soxhlet and accelerated solvent extraction, using propanol as a solvent, and supercritical CO2 extraction methods presented statistically insignificant differences in the crude oil yield obtained from spent coffee grounds.

Stability of rice bran oil extracted by SFE and soxhlet methods during accelerated shelf-life storage

open access: yesGrasas y Aceites, 2014
Supercritical fluid high oryzanol (SFE HO) and supercritical fluid low oryzanol (SFE LO) rice bran oils were obtained and compared with that extracted by the Soxhlet (SOX) method. Their composition and stability during storage were determined. The amount

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Effects of Molecular Designs and Double‐Network Morphologies for Bioadhesive Semiconductors

open access: yesAdvanced Functional Materials, EarlyView.
This study establishes molecular‐to‐mesoscale design rules for bioadhesive semiconducting polymers (BASCs). It identifies how side‐chain length, double‐network formation, and film thickness modulate adhesion strength and electronic performance, providing insight into the rational design of intrinsically adhesive semiconductors for stable and efficient ...

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.
