Laser‐Induced Graphene from Waste Almond Shells

Advanced 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.

Crude Glycerol as an Innovative Corrosion Inhibitor

Applied System Innovation, 2018
Crude glycerol, a byproduct of biodiesel production, was evaluated as a potential green inhibitor for steel corrosion in an acidic environment. The study was conducted using steel specimens placed in hydrochloric acid solutions (0.5 M) at a constant room temperature (25 °C) and crude glycerol concentrations in the range 0.1%–1.0% w/w. The criteria used

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots

Advanced Functional Materials, EarlyView.
This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.

Production of PHB from Crude Glycerol

Engineering in Life Sciences, 2007
AbstractCrude glycerol – a by‐product of the large scale production of diesel oil from rape – is examined for its possible use as a cheap feedstock for the biotechnological synthesis of poly(3‐hydroxybutyrate) (PHB). The glycerol samples of various manufacturers differ in their contamination with salts (NaCl or K2SO4), methanol or fatty acids.

Stability of Medicinal Nanoemulsions to Spaceflight: Insights From the StarMed Experiment

Advanced Healthcare Materials, EarlyView.
Chitosan‐coated melatonin nanoemulsions (MN) recovered from a sounding rocket mission preserve droplet size and controlled‐release behavior, whereas uncoated nanoemulsions show ageing‐driven droplet growth and increased accessible drug fraction. Simple polymer coatings thus enhance the flight resilience of liquid space medicines under cumulative launch
