The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Empa researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.
Derived from crude oil, toxic to synthesize, and slow to degrade, polyurethanes are not environmentally friendly. Today, researchers discuss a safer, biodegradable alternative derived from fish waste that would otherwise likely be discarded. They will present their results at ACS Spring 2021.
New research in ACS Nano describes a way to make flexible temporary electronic displays from fish scales.
“Bioplastics—a better option for the environment?” is a compilation of information about bioplastics. These alternative plastics have become more popular, and as it turns out, they’re effectively still the same as petroleum-based plastic, according to Dr. McGuire’s document.
