High frequency radio waves can wirelessly carry the vast amount of data demanded by emerging technology like virtual reality, but as engineers push into the upper reaches of the radio spectrum, they are hitting walls. Literally.

Ultrahigh frequency bandwidths are easily blocked by objects, so users can lose transmissions walking between rooms or even passing a bookcase.

Now, researchers at Princeton Engineering have developed a machine-learning system that could allow ultrahigh frequency transmissions to dodge those obstacles...

A team of scientists from Korea and Japan has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices.

The newly developed material is a special kind of metal oxide made of strontium, iron, and cobalt...

Imagine a safe gamma ray laser that could eradicate cancer cells without damaging healthy tissue. A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality.

Imagine a safe gamma ray laser that could eradicate cancer cells without damaging healthy tissue. Or a tool that could help determine if Stephen Hawking’s multiverse theory is real by revealing the fabric underlying the universe.

Assistant Professor of Electrical Engineering Aakash Sahai, PhD, has developed a quantum breakthrough that could help those sci-fi ideas develop and has sent a ripple of exciteme...

Aerospace engineering and materials science researchers at Texas A&M University have uncovered new properties of an ultra-durable, recyclable, smart plastic—paving the way for transformative applications in the defense, aerospace and automotive industries.

The research, published in Macromolecules and the Journal of Composite Materials, was led by Dr. Mohammad Naraghi, director of the Nanostructured Materials Lab and professor of aerospace engineering at Texas A&M, in close collaboration with Dr. Andreas Polycarpou at The University of Tulsa.

Their work explored the mechanical integrity, shape-recovery and self-healing properties of an advanced carbon-fiber plastic composite called Aromatic Thermosetting Copolyester (ATSP).

Healing damage on demand
ATSP opens new frontiers i...
