HOUSTON - (May 6, 2021) - A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.
Laser-induced graphene (LIG), introduced in 2014 by Rice chemist James Tour, involves burning away everything that isn t carbon from polymers or other materials, leaving the carbon atoms to reconfigure themselves into films of characteristic hexagonal graphene.
The process employs a commercial laser that writes graphene patterns into surfaces that to date have included wood, paper and even food.

CHAMPAIGN, Ill. Some of the world s greatest innovations, such as Leonardo da Vinci s flying machine, owe their strength and elegance to natural design. Researchers from the University of Illinois Urbana-Champaign have returned their gaze to the natural world to develop a camera inspired by the mantis shrimp that can visualize cancer cells during surgery.
A new study led by electrical and computer engineering professor Viktor Gruev details how the new camera works with tumor-targeted drugs to see cancer in animal and human patients. The study is published in the journal
Science Translational Medicine. Engineers spend incredible amounts of time and money developing the image sensors in cellphones, said Gruev, who also is affiliated with Carle Illinois College of Medicine. When we are out on the town, these devices can capture pictures that are perfect for social media, but when doctors are examining patients, they don t care how nice the shot looks - they care how w
By THOMAS GNAU | Dayton Daily News | Published: April 28, 2021 WRIGHT-PATTERSON AFB, Ohio (Tribune News Service) When Brig. Gen. Heather Pringle took command of Air Force Research Laboratory (AFRL) at Wright-Patterson Air Force Base last year, she outlined her top goals. Chief among those: Orienting AFRL to support not just the Air Force, but the new Space Force. Being one AFRL supporting two services was in my top three. In fact it was No. 2. Pringle said Wednesday in an online roundtable. AFRL is based at Wright-Patterson, making the base not just Ohio s largest single-site employer with 30,000 military and civilian employees, but an increasingly crucial base for two military branches.

DURHAM, N.C. - Engineers at Duke University have developed the world s first fully recyclable printed electronics. By demonstrating a crucial and relatively complex computer component the transistor created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable electronics to help fight the growing global epidemic of electronic waste.
