Researchers turn cement into metal
(Phys.org) —In a move that would make the Alchemists of King Arthur's time green with envy, scientists have unraveled the formula for turning liquid cement into liquid metal. This makes cement a semi-conductor ...
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 ...
Environmentally friendly cement is stronger than ordinary cement
New research from the Niels Bohr Institute shows that cement made with waste ash from sugar production is stronger than ordinary cement. The research shows that the ash helps to bind water in the cement so ...

Why cement tends to thicken
Researchers at the ETH Zurich have unraveled the microscopic mechanism behind shear thickening: the increase in viscosity with speed observed for dense particle suspensions under flow. The study has a direct ...
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 ...
CO2 emissions +2.2% in 2012, driven by China and coal
Emissions of carbon dioxide from fossil fuels and cement production reached a new high in 2012, rising 2.2 percent over 2011 due chiefly to an increase in coal-burning China, scientists said Tuesday.
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.
