HEADLINES ARCHIVE
First Citywide Test of Radioactivity
A key element of SIGMA, which began in 2014, has been to develop and test low-cost, high-efficiency radiation sensors that detect gamma and neutron radiation.
Biocomposite Bridge Opens in the Netherlands
To develop the biocomposite, fibers were stuck to a biological polylactic acid foam core, after which a bioresin was sucked into the fiber layers using a vacuum to produce a strong girder.
Bio-Derived Glue Holds Together Underwater
Mussels secrete a combination of natural liquid superglues and stretchy fibers, called byssal threads, that adhere equally well in saltwater and freshwater.
Flow Accelerated Corrosion: An Ongoing Risk for Steam Generators
Thirty years after four workers died at a Virginia nuclear power plant, the problem of flow accelerated corrosion remains a concern.
Surfaces Repel Both Water in Oil and Oil in Water
To date, the ability to repel water when covered by oil, and oil when covered by water, has been regarded as contradictory.
Turning the Living Room into a Wireless Charging Station
The proposed system would operate at microwave frequencies, at which the power transfer distance could extend well beyond the confines of a room.
Wildfire Emissions Analyzed for Health, Climate Effects
A special chamber allows controlled combustion of fuels under flaming and smoldering conditions, after which the emitted smoke particles are aged photochemically in a flow tube reactor.
Spinach Plants Engineered to Detect Explosives
This is one of the first demonstrations of the engineering of electronic systems into plants.
Rewritable Material Could Reduce Paper Waste
The material, made out of tungsten oxide and a common polymer used in medicines and food, avoids use of the toxic, expensive organic dyes associated with other such products under development.
"Perfect" Soap Molecule Invented
Conventional soaps and detergents are generally viewed as environmentally unfriendly because they are made from fossil fuels.
Ice Is No Match for This New Coating
Researchers have invented an ice-repellent coating that tests show out-performs today's best de-icing products.
The New "Fog of War?"
The most common source for pyrotechnic obscurants is still powdery red phosphorus, although it can be unsafe to handle, burns relatively sluggishly and can release toxic phosphine.
Biodegradable, Drug-loaded Fiber Is Introduced
New biodegradable fiber can be loaded to deliver drugs, vaccines, and even cells or live viruses to the body exactly where needed.
Carbon Nanotube Dry Adhesive Sticks in Extreme Temps
A carbon nanotube dry adhesive that bonds in extreme temperatures got its inspiration from the wall-walking gecko.
Material Contracts When Heated
Most materials, such as those used to make buildings or bridges, expand when they become hot. For this reason, expansion joints are needed to allow the materials to swell without buckling.
Microbe Could Help Cut Methane Emissions
While there have been numerous indications that iron-dependent methane oxidizers existed, researchers have never been able to isolate them.
Gold Nanowires Allow Operations at Cellular Level
Conventional surgical tools, including electrodes that are implanted in people's tissue, are unfavorably large on the cellular level.
Electricity Used to Track Water, Identify Concrete Degradation
The technology can determine where and whether water is infiltrating concrete, as well as how fast it is moving, how much water there is and how existing cracks are influencing the water movement.
Could Bacteria Create Building Foundations?
Researchers are modifying E. coli bacteria to create a "gene circuit" that would enable the bacteria to respond to their environment by producing biocements.
Mass Plywood Panel to Compete in Timber Market
Mass plywood panel is a large-scale panel designed to be an alternative to cross-laminated timber.
