Solar – Made to order …
— With the addition of a dash of a common solvent, researchers realized an efficiency gain of about 36 percent for organic solar cells. A team led by Oak Ridge National Laboratory’s Kai Xiao added diiodooctane – 3 percent of the weight of the entire solution – to a blend of polymers and fullerene derivatives and saw the cell’s power conversion efficiency jump from 4.

Computing – Smarter oil exploration …
— An innovative computational tool developed at Oak Ridge National Laboratory could reduce uncertainties and the time required to decide where to drill for gas and oil.

Vehicles – ORNL inverter licensed …
— Oak Ridge start-up New Hybrid Technologies has licensed a power conversion technology developed by Gui-Jia Su of Oak Ridge National Laboratory’s Power Electronics and Electric Machinery group.

Batteries – 10,000 charges …
— With the demonstration of a 5-volt thin-film battery that can be charged and discharged 10,000 times, Oak Ridge National Laboratory’s Juchuan Li and Nancy Dudney are entering new territory. Consumers could be the big beneficiaries because these batteries boast higher energy for the same weight, lower cost and longer life.

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.

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.
