Solid state from a fragile source?

It’s possible that future computers could have memory devices based on eggshells as researchers at the Guizhou Institute of Technology have been prototyping a new form of solid-state memory. Eggshells were processed to form a material that changed its resistance in response to a voltage being applied across it thus making it suitable for use as a ReRAM (resistive random access memory) device. This egg-centric research might offer the possibility of an environmentally friendly, low-cost and sustainable material for the next-generation of non-volatile date storage device.

A cracking idea

A big theme in textiles and materials development at the moment is sustainability and recycling so this story about egg packaging made of eggs has scrambled our minds.

Researchers as Tuskegee University added egg shell nanoparticles (350,000 times smaller than the diameter of a human hair) to a plastic polymer consisting of 30% PLA (polylactic acid, a polymer derived from cornstarch) and 70% PBAT (polybutyrate adipate terephthalate, a petroleum polymer that, unlike other oil-based plastic polymers, is designed to begin degrading as soon as three months after it is put into the soil). This resulted in a material that was 700% more flexible than other bioplastic blends and this pliability could make it ideal for use in retail packaging, grocery bags and food containers — including egg cartons.

How amazing to be able to make a valuable material out of a waste product!
