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 earthquakes
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.
Safe harbor: Freight transport logistics
One of the most important means of connecting with foreign countries is by sea, especially for the transport of freight. Researchers are assessing harbor safety using simulations in order to help provide smooth and efficient navigation.
Improving the stability of clay for construction
New research set out to improve the engineering quality of clay using waste materials and a secret binder ingredient. Clay is a natural material composed primarily of fine-grain minerals. It consists of tiny particles that have plastic and adhesive properties. Clay also possesses small voids and por...
One of world''s thinnest piezoelectric materials identified
There are a handful of naturally occurring materials, known as piezoelectric materials, that generate electricity if you bend, stretch or apply another mechanical force to them, and vice versa -- if you apply a voltage across them, they''ll deform accordingly. These materials are currently the subje...
Inspired by nature, researchers create tougher metal materials
Drawing inspiration from the structure of bones and bamboo, researchers have found that by gradually changing the internal structure of metals they can make stronger, tougher materials that can be customized for a wide variety of applications -- from body armor to automobile parts.
Muscle-powered bio-bots walk on command
A new generation of miniature biological robots is flexing its muscle. Engineers have demonstrated a class of walking ''bio-bots'' powered by muscle cells and controlled with electrical pulses, giving researchers unprecedented command over their function.
New bridge design improves earthquake resistance, reduces damage and speeds constructionStories 1 - 10 of 151
Researchers have developed a new design for the framework of columns and beams that support bridges, called ''bents,'' to improve performance for better resistance to earthquakes, less damage and faster on-site construction.
