Oil Well Fissures Plugged with Bacteria
Typically, well leaks are repaired using cement. But sealing small fissures is difficult because of cement's high viscosity.
Underground Radar for Post-Katrina Damage
The technology is a pipe-penetrating scanning system that uses ultra-wide-band pulsed radar.
I, Cobot: Standardizing Safety in Collaborative Robots
A new technical specification provides guidance on safety requirements for robot systems that work alongside humans.
Non-powered Dams: An Untapped Source of Electricity?
An Energy Department report says U.S. hydropower could grow to 150GW of capacity by 2050, much of it from currently non-powered dams.
Warming Climate Impact on Power Plant Output
The study rebuts recent modeling-based research that warns rising temperatures will significantly lower the efficiency of power plants’ cooling systems, reducing their energy output.
Cold Start Engine Emissions
Almost all emissions in properly functioning new vehicles came out immediately after starting the cars when their engines were cold.
Plasma Etching of Biochar Reduces Supercapacitor Costs
The ability to absorb and discharge energy quickly makes supercapacitors integral to energy harvesting.
Workshops Impart Lessons
Workshops attempt to demystify what happens during an accident to help engineers/operators learn what decisions they might need to make in the event of a nuclear plant mishap.
Brain-Machine Interface Triggers Recovery
WAP says theirs is the first study to report that long-term brain-machine interface use could lead to significant recovery of neurological function in patients suffering from severe spinal cord injuries.
Plastics Manufacturing Process Could Cut Energy Use
The process uses reverse osmosis to separate a chemical building block used for polyester and plastics from complex hydrocarbon mixtures.
Nanocrystal-generated Light Could Speed Communications
White light generated using semiconductor lasers may one day replace LED white-light bulbs for energy-efficient lighting, researchers say.
Controlling Bubbles for Industrial Uses
While bubbles are observed frequently in nature, it is not easy to control their diameter, position, or time of formation.
BP-backed Research Aims to Detect Pipeline Damage Before Failure
Fluids that hold fluorescent indicators can be embedded in materials and, when damage occurs, release the marker to signal that repair is needed.
Methane Emission Sources ID'd from the Air
Similar flights could help develop strategies for meeting federal limits on methane emissions from the oil and gas industry.
Torrential Downpours Predicted with Greater Accuracy
Researchers produced a high-resolution, three-dimensional distribution map of rain every 30 seconds which is 120 times faster than the hourly updated systems used by weather prediction centers today.
Liquid Light Switch for More Powerful Electronics
Current methods of converting between electrical and optical signals are both inefficient and slow, and researchers have been searching for ways to combine the two.
A Simplified Way to Recycle Carbon Fiber?
The method involves soaking the composite in an alcohol solvent, which dissolves the epoxy that binds and gives shape to the carbon fibers.
USDA Aims to "Milk" Sustainable Food Packing
A film made of milk protein is biodegradable, sustainable, and edible.
