OLIVER SPRINGS—Another convenience store was hit by a vehicle this weekend, this one in Oliver Springs, and police suspect it was intentional.

The crash, which was reported at about 2:08 a.m. Sunday, smashed a door at Lee’s Food Mart on East Tri County Boulevard in Oliver Springs, at the bottom of the hill coming into Oliver Springs from Oak Ridge.

That crash followed one at K&J Market at about 2 a.m. Saturday in west Oak Ridge. In that case, a small sport utility vehicle was captured on tape smashing the front door of the convenience store, but it’s not clear why, a business representative said Saturday morning.

The Oliver Springs Police Department said the alarm at Lee’s Food Mart went off after an SUV hit it early Sunday, and nothing was taken. The SUV fled toward Oliver Springs, OSPD Sergeant Kevin Armes said. [Read more…]

SEATTLE—University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics, thanks in part to a breakthrough by researchers at Oak Ridge National Laboratory and University of Tennessee in Knoxville.

The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices.”

Most consumer electronics use three-dimensional LEDs, but they are up to 20 times thicker than the LEDs being developed. [Read more…]
