Research Bits: Nov. 19


Starchy nanocomposite films Researchers from Queen Mary University of London created biodegradable, flexible, and electrically conductive nanocomposite films made using potato starch instead of petroleum-based materials. The starch-based films decompose within a month when buried in soil. In addition to starch, the nanocomposite films contain the conductive 2D material MXene. Adjusting the ... » read more

Making PUFs Even More Secure


As security has become a must-have in most systems, hardware roots of trust (HRoTs) have started appearing in many chips. Critical to an HRoT is the ability to authenticate and to create keys – ideally from a reliable source that is unviewable and immutable. “We see hardware roots of trust deployed in two use models — providing a foundation to securely start a system, and enabling a se... » read more
