Video: Rising e-waste and a deficit of recycling

By Lisa McDonald / July 8, 2020

In 2017, a report on global e-waste predicted the amount of e-waste would increase to 52.2 million metric tonnes by 2021—but we already passed 53 million metric tonnes in 2019 alone, according to a new report released this month. Learn more about why e-waste amounts are surging, why current recycling systems are not keeping up, and what can be done to combat the problem.

Data that lasts—modification of ferroelectric transistor structure improves memory retention

By Lisa McDonald / March 10, 2020

Ferroelectric field-effect transistors are nonvolatile memory devices that nondestructively read stored data. However, data retention times in these devices are short. Purdue University researchers suggest a modification to conventional Fe-FET structure could overcome this obstacle.

The best of both worlds—ferroelectric crystals exhibit both high transparency and piezoelectricity

By Lisa McDonald / February 7, 2020

Previous attempts to increase transparency of ferroelectric crystals have decreased piezoelectricity. An international team of scientists led by The Pennsylvania State University and Xi’an Jiaotong University now shows that selective engineering of domain walls can improve both properties.

Video: Incandescent light bulbs—the fading stalwarts of U.S. lighting

By Lisa McDonald / January 15, 2020

Since 2007, more energy-efficient lighting has been replacing incandescent light bulbs in preparation of federal standards set to become effective this year. The Trump administration rejected these standards last month, but incandescent bulbs still are on their way out.
