Around 30 percent of the world's biosolids are stockpiled or sent to landfill each year, while over 3 billion cubic meters of clay soil is dug up for the global brickmaking industry. Using biosolids in bricks offers an innovative solution to these environmental challenges.
Kanazawa University researchers discovered that the distance between dislocations in nanolayer interfaces of pearlite can determine how much the material can stretch or contract without breaking (ductility). The dislocations are disruptions in the regular arrangements of atoms in nanolayers. This discovery opens the possibility of engineering materials with higher ductility by simply manipulating the spacing between their dislocations and may improve the safety of structures such as buildings and bridges in earthquakes.
Research shows that drones can be more effective and safer in crash mapping of vehicular highway accidents than conventional methods. Drones using new imaging technology developed at Purdue University allows highway safety officers to capture and print 3D composites of crash sites and reduce mapping time and improve traffic flow following a crash by 60 percent.
New research, led by the University of Leicester, will optimise the welding and additive and manufacturing process
Keeping road pavement in good shape saves money and energy and reduces greenhouse gas emissions, more than offsetting pollution generated during road construction, according to a Rutgers-led study. The study appears in the International Journal of Sustainable Transportation.
To reduce the risk of fire, many everyday products -- from building materials to furniture to clothing -- contain flame retardants. In recent years, some of these compounds were shown to have harmful effects on the environment, causing them to be replaced by more eco-friendly alternatives. However, a new study in ACS' journal Environmental Science & Technology, indicates that heat or ultraviolet light could break down a 'safe' flame retardant into potentially harmful compounds.
A pair of new studies from researchers at The Ohio State University offers a possible solution to water scarcity, inspired by nature.
A new study in Environmental Geosciences is the first to predict -- with up to 87 percent accuracy -- which oil and natural wells are most likely to be leaking methane. Research published in Science estimated that natural gas wells are leaking 60 percent more methane than the EPA estimates, offsetting much of the fuel's climate benefit.
Researchers have used a method, using the RANS compact neutron source, to non-destructively measure the salt content of structures such as bridges, tunnels, and elevated roadways, which can suffer from degradation due to exposure to salt from seawater and other sources.
Researchers argue in a new study that a paradigm shift is needed for assessing bridges' tsunami risk.
