Bio-based materials used to salvage rare earth elements — ScienceDaily

What do corncobs and tomato peels have to do with electronics? They both can be used to salvage valuable rare earth elements, like neodymium, from electronic waste. Penn State researchers used micro- and nanoparticles created from the organic materials to capture rare earth elements from aqueous solutions.

Their findings, available online now, will also be published in the November issue

Robust C++: Initialization and Restarts

In a large system, main() can easily become a mess as different developers add their initialization code. This article presents a Module class that allows a system to be initialized in a structured, layered manner. It then evolves the design to show how the system can perform a quick restart, rather than a reboot, to recover from serious errors such … Read More
