Automobiles – Particulate matter paradox …
— Cars with gasoline direct-injected engines are helping automakers meet stricter government fuel economy standards, but they’re emitting five to 10 times more particulate matter than their port fuel-injected counterparts. This is the finding of researchers in Oak Ridge National Laboratory’s Fuels, Engines and Emissions Research Center.

Energy – Super smart sensors …
— A new generation of low-cost, low-power wireless sensors being developed at Oak Ridge National Laboratory will be put to the test at the lab’s new flexible research platform, which is part of the Maximum Building Energy Efficiency Research Laboratory.

Cyber – Protection for utilities …
— Hackers hoping to disrupt the power grid, water or natural gas service may be foiled by an intrusion detection system developed by researchers at Oak Ridge National Laboratory. The system is an expanded version of Oak Ridge Cyber Analytics, which boosts the performance of existing cyber attack systems by filtering noise and quickly making sense of massive amounts of data.

Materials – Vehicle lightweighting …
— For about the price of leather seats, automakers can trim approximately 362 pounds off the body and chassis of a midsize passenger vehicle, according to an Oak Ridge National Laboratory study. Researchers analyzed an array of materials – carbon fiber, advanced high-strength steel, aluminum alloys, magnesium alloys – that could replace steel.

Optics – Precision projectile tracker …
— Rifle optical sighting systems with a 19th century heritage could blast into modern times with a laser-based bullet tracking system being developed by a team led by Slobodan Rajic of Oak Ridge National Laboratory.

Medical – Needles in the eye …
— Surgeons treating the millions of people who suffer from a variety of eye conditions, including recurrent corneal erosions, have a new instrument its developers believe will result in better outcomes. Plexitome is a corneal instrument that acts as thousands of microscopic needles to imprint the patient’s corneal tissue, allowing the tissue to heal more quickly and completely.

Vehicles – Connected to savings …
— Drivers, their wallets and the environment could benefit from a connected vehicle system that could collectively save them from wasting 5.5 billion hours in traffic jams and nearly 3 billion gallons of fuel.

Computing – Titan’s protégé …
— For students learning about multicore computers like Titan, the second-most powerful computer in the world, Tiny Titan can make the task a bit more manageable. The sub-$1,000 classroom computer can help middle and high school students explore the fundamental concepts of parallel computing, which is the key to Titan and its 299,008 cores.

Materials – Transparent ballistic results …
— Glass used for military vehicle windshields is being put to the test by an Oak Ridge National Laboratory team evaluating different formulations for mechanical strength, high pressure and shock response.

Energy – CO2 to the rescue …
— Tomorrow’s commercial refrigeration systems – like the ones in supermarkets – could be cooled by carbon dioxide instead of hydrofluorocarbons, a greenhouse gas that is nearly 4,000 times more potent than CO2.
