Drexel Materials science researchers demonstrate MXene polymer coating can block and absorb interference. A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to one another. A special coating that they developed, using a type of two-dimensional material called MXene, has shown to be capable of absorbing and disbursing the electromagnetic fields that are the source of the problem.

Buzzing, feedback or static are the noticeable manifestation...

Distinguishing this intrigung material behavior at small scales could reduce energy demands for computing. As electronic devices become smaller and smaller, the materials that power them need to become thinner and thinner. Because of this, one of the key challenges scientists face in developing next-generation energy-efficient electronics is discovering materials that can maintain special electronic properties at an ultrathin size.

Advanced materials known as ferroelectrics present a promising solution to help lower the power consumed by the ultrasmall electronic devices found in cellphones and computers...

Discarded electronic devices, such as cellphones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers reporting in ACS Applied Materials & Interfaces have created a prototype circuit board that is made of a sheet paper with fully integrated electrical components, and that can be burned or left to degrade.

Most small electronic devices contain circuit boards that are made from glass fibers, resins and metal wiring...

Computer security experts have developed a system capable of guessing computer and smartphone users’ passwords in seconds by analyzing the traces of heat their fingertips leave on keyboards and screens.

Researchers from the University of Glasgow developed the system, called ThermoSecure, to demonstrate how falling prices of thermal imaging cameras and rising access to machine learning are creating new risks for “thermal attacks.”

Thermal attacks can occur after users type their passcode on a computer keyboard, smartphone screen or ATM keypad before leaving the device unguarded...
