Solar energy that doesn''t block the view
Researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has ...
Wireless sensors and flying robots: A way to monitor deteriorating bridges
As a report from the Obama administration warns that one in four bridges in the United States needs significant repair or cannot handle automobile traffic, engineers are employing wireless sensors and flying robots that could have the potential to help authorities monitor the condition of bridges in...
New material structures bend like microscopic hair
Engineers have fabricated a new elastic material coated with microscopic, hairlike structures that tilt in response to a magnetic field.
Learning how things fall apart: How bonded materials, from airplane wings to dental crowns, lose their bonding
Materials that are firmly bonded together with epoxy and other tough adhesives are ubiquitous in modern life -- from crowns on teeth to modern composites used in construction. Yet it has proved remarkably difficult to study how these bonds fracture and fail, and how to make them more resistant to su...
Neutron tomography technique reveals phase fractions of crystalline materials in 3-dimensions
Researchers have developed a novel method, based on energy-selective neutron imaging for visualization of crystalline phase distributions within the bulk of metallic samples.
Building ''invisible'' materials with light
A new technique which uses light like a needle to thread long chains of particles could help bring sci-fi concepts such as cloaking devices one step closer to reality.
Fires are major cause of wind farm failure, according to new research
Fire is the second leading cause of accidents in wind turbines, after blade failure, according to research. Wind farming is one of the leading industries in the renewable energy sector. However, the industry faces a number of challenges, such as opposition by wind farm lobbyists. Today''s research s...
Bioprinting methods on 2-D surfaces to link 3-D cellular structures
New research focuses on the development of a novel, matrix-free method for generating 3-D cell spheroids that are combining knowledge from bioprinting methods on 2-D surfaces to link 3-D cellular structures.
Efficient structures help build a sustainable future
Researchers have found that the selection of steel cable structural system for long spans has considerably less environmental impact than a steel truss system to achieve the same structural requirements, through the entire life cycle of the structure. "Thoughtful selection, by the architectural engi...
70-foot-long, 52-ton concrete bridge survives series of simulated earthquakesStories 1 - 10 of 140
A 70-foot-long, 52-ton concrete bridge survived a series of earthquakes in the first multiple-shake-table experiment in the University of Nevada, Reno''s new Earthquake Engineering Lab, the newest addition to the world-renowned earthquake and seismic engineering facility.
