In a controlled environment, the fastest-growing orientation of graphene crystals overwhelms the others and gets "evolutionarily selected" into a single crystal, even on a polycrystalline substrate, without having to match the substrate’s orientation.

Method to grow large single-crystal graphene could advance scalable 2D materials

A new method to produce large, monolayer single-crystal-like graphene films more than a foot long relies on harnessing a “survival of the fittest” competition among crystals. The novel technique, developed by a team led by the Department of Energy’s Oak Ridge National Laboratory, may open...

Sensible driving saves more gas than drivers think

It’s common knowledge that driving aggressively can dent gas mileage, but it’s difficult to determine exactly how much gas drivers waste. A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory has quantified the impact speeding and slamming on the brakes...

Homes get smart

Ways to give homeowners more centralized control over how much electricity their home uses—from the air conditioning unit to the heat pump water heater—are being developed by Oak Ridge National Laboratory. An ORNL team is working with Southern Company and Alabama Power on its Smart...

Neutrons peer into a running engine

In a first-of-a-kind experiment, researchers used neutrons to investigate the performance of a new aluminum alloy in a gasoline-powered engine—while the engine was running. A team from the Department of Energy’s Oak Ridge National Laboratory worked with industry partners to perform the...

Buildings: Airtight savings

A new tool developed at Oak Ridge National Laboratory can help homeowners and builders calculate energy loss when air leaks through a building’s envelope, the physical barrier separating the interior and exterior. Starting with specific building metrics, the calculator analyzes multizone...

Tailoring component performance by combining 3D printing, casting

A new manufacturing method created by Oak Ridge National Laboratory and Rice University combines 3D printing with traditional casting to produce damage-tolerant components composed of multiple materials. Composite components made by pouring an aluminum alloy over a printed steel lattice...
