Shrimp-like crustacean found to make gooey underwater silk
Recipe for success: Recycled glass and cement
(PhysOrg.com) -- Michigan State University researchers have found that by mixing ground waste glass into the cement that is used to make concrete, the concrete is stronger, more durable and more resistant ...
Cement's basic molecular structure finally decoded
(PhysOrg.com) -- In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular ...
Engineers develop cement with 97 percent smaller CO2 and energy footprint
Drexel engineers have found a way to improve upon ordinary Portland cement (OPC), the glue that's bonded much of the world's construction since the late 1800s. In research recently published in Cement and Concrete Composites ...
Chemically scrubbing CO2 from the air too expensive
(PhysOrg.com) -- While it is possible to chemically scrub carbon dioxide from Earth's atmosphere in order to lessen the severity of global warming, the process is prohibitively expensive for now. Best to focus ...
SequesTech: A novel process to capture and mineralize flue gas carbon dioxide
(PhysOrg.com) -- A process that directly captures flue gas carbon dioxide from the combustion process and holds it has earned a patent for the University of Wyoming.
Fossil-fuel emissions unbraked by financial crisis
Emissions of carbon dioxide (CO2) from fossil fuels and the cement industry scaled a record high in 2010, rocketing by 5.9 percent over 2009 in a surge led by developing countries, scientists reported on Sunday.
BP says cap catching some 10,000 barrels a day
Engineers searched for ways to capture more oil flowing from a ruptured well in the Gulf of Mexico Sunday after energy giant BP said a cap was currently catching around 10,000 barrels a day.
Attempt at 'top kill' method to clog oil leak delayed
A make-or-break attempt to clog a ruptured pipe gushing oil into the Gulf of Mexico with a method dubbed the "top kill" has been delayed until at least Tuesday, officials said Friday.
The Achilles' heel of tendons
Tendons are the body's marionette strings, connecting bones to muscles that raise an eyebrow or propel us into a full run. That is, until an unusually forceful or awkward pull on the strings leaves us with a sprain, strain ...
Groundbreaking mercury treaty adopted by 140 countries (Update)
More than 140 countries agreed Saturday on a ground-breaking treaty to rein in the use and emission of health-hazardous mercury, the UN said, but environmental activists lamented it did not go far enough.
Bismuth for bone cement: Water-soluble cluster key to the formation of hybrid material
(PhysOrg.com) -- Organicinorganic hybrid materials, uniting the advantages of their organic and inorganic parts, are used for a wide variety of applications. However, making a homogeneous composite material ...
Effect of CO2 on the integrity of well cement examined
Geologic carbon storage is the separation and capture of carbon dioxide (CO2) from large stationary sources, such as power plants, followed by injection into deep geologic formations. Long-term storage of ...
From downcycling to recycling: Using lighting to separate cement particles from stone
Every year several millions of tons of building rubble are produced. An efficient way of recycling concrete – the building material of the 20th and 21st century – does not yet exist. Researchers are working ...
