The use of solar tracking technology can improve production at PV farms by anywhere from 15-30% when compared to a fixed-tilt system.
Defects Actually Strengthen Roman-era Concrete
Small defects known as screw dislocations help account for the superiority of the Roman Empire’s concrete.
Imaging Technique Identifies Individual Neurons
A new method for imaging the human retina gave researchers the first look at individual retinal ganglion cells.
Nanowire Inks for Paper-Based Printable Electronics
A new study by Duke researchers shows that tweaking the shape of the nanoparticles in the ink might just eliminate the need for heat.
Jump in Green Tech Needed to Meet Emission Goals: Duke
The climate warming goals set by the Paris Agreement will not be met unless the spread of clean technology can speed up by a full order of magnitude, or about 10 times faster than in the past.
Biometric Security: Your Body as Your Password
Biometric security has proven to be an effective and convenient way to bolster security, especially on mobile devices, which have the technology built-in.
Wind Turbines May Benefit Certain Crops
Turbulence produced by wind turbines leads to temperatures about a half-degree cooler during the day and between a half to a full degree warmer at night.
Sensor Technology Could Lighten EV Batteries
The researchers say their system is suitable not only for batteries in electric vehicles, but for other energy storage systems as well, including those in mobile devices such as tablets and laptops.
Process Could Yield Trans Fat-Free Soybean Oil Product
The intense heat required in the conventional hydrogenation process causes the formation of harmful trans fats.
Plastic Solar Cells with Broader Sunlight Absorption
As plastic solar cells now rival silicon-based solar cells in power conversion efficiency, researchers want to increase the range of photonic energies that they can absorb.
Pipelines More Efficient Than Rail for Long-Hauling Oil
Comparing the energy consumed in construction and operation for both methods, researchers found that pipeline transportation produced 61%-77% less greenhouse gas emissions than rail.
Tight Tolerances Achieved on Massive Parts
Where parts cut on other equipment often require further processing to reach final tolerance, waterjetting may enable shops to achieve that tolerance in a single operation.
