Limited Options for HFC Replacements
A four-year study sought nonflammable, low-global warming potential alternatives to HFCs for small air-conditioning systems.
A Solution for Wastewater Treatment Plant Stink
Identifying various odors, which run the gamut from burnt matches to rotten eggs to fecal matter, is a challenge at wastewater treatment plants.
How Do Ball Valves Work?
Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves are used in situations where tight shut-off is required.
Red Lion Announces Highly Scalable Graphite Edge Controller for Extreme Environments
Red Lion Controls announced the new Graphite® Edge Controller, a compact rugged industrial controller offering highly scalable I/O and combining networking and data visualization with industry standard IEC 61131 control capabilities in a small, easy-to-deploy footprint.
Warning of Shortage of Essential Minerals for Laptops, Cell Phones, Wiring
An international team of researchers, led by the University of Delaware's Saleem Ali, says global resource governance and sharing of geoscience data is needed to address challenges facing future mineral supply.
Undergraduate Researcher's Results Could Improve Filtration Processes
A Penn State senior’s recently published research focuses on factors that could improve coal slurry filtration.
Engineering Team Develops Nanofiber Solution for Clean, Fresh Air
A research team from the National University of Singapore (NUS) has successfully concocted a novel nanofiber solution that creates thin, see-through air filters that can remove up to 90 percent of PM2.5 particles and achieve high air flow of 2.5 times better than conventional air filters.
Pulverizing Electronic Waste Is Green, Clean — and Cold
Researchers at Rice University and the Indian Institute of Science have an idea to simplify electronic waste recycling: Crush it into nanodust.
Preventing Lead Spread
A team of engineers at Washington University in St. Louis has developed a new way to model and track where lead particles might be transported during the partial-replacement process, in an effort to keep the water supply safer.
Silk Sensor Could Speed Development of New Infrastructure, Aerospace and Consumer Materials
Consumers want fuel-efficient vehicles and high-performance sporting goods, municipalities want weather-resistant bridges and manufacturers want more efficient ways to make reliable cars and aircraft. What’s needed are new lightweight, energy-saving composites that won’t crack or break even after prolonged exposure to environmental or structural stress.
Methane Reforming in Four-Stroke Engine Cycle
A modular reforming reactor could provide hydrogen at the point of use for residential fuel cells and vehicle refueling stations.
Car Tires: Where the Trees Hit the Road
Fossil fuel-derived isoprene for tire manufacture might soon be replaced with isoprene produced from trees, grasses, or corn.
Got Soybeans? Make Graphene
A simplified single-step process for graphene fabrication has been developed by Australian researchers.
Exhaust Fumes as a Resource
A research team headed by Professor Dr. Markus Heinrich, Medicinal Chemistry, FAU has now developed a highly efficient method of combining these two aspects — namely the purification of waste gas outflows and the practical recycling of nitrogen oxides.
Researcher Tests Fly Ash for Stronger Concrete
Portland cement has been around for more than 250 years as the binding material for concrete, mortar and stucco, but a Missouri University of Science and Technology researcher is studying ways to make concrete without the traditional material.
Researchers Offer Overview of Composite Metal Foams and Potential Applications
Researchers at North Carolina State University have developed a range of composite metal foams (CMFs) that can be used in applications from armor to hazardous material transport — and they're now looking for collaborators to help identify and develop new applications. To that end, the researchers are issuing a comprehensive overview and new data on their CMFs.
New Nanofiber Marks Important Step in Next Generation Battery and Water Electrolysis Development
One of the keys to building electric cars that can travel longer distances, or powering more homes with renewable energy, is developing efficient and highly-capable energy storage systems.
EnviroPump and Seal: Designed Not to Fail
Longer life bearings and seals for new pumps and retrofits increase life and reduce maintenance.
New Material Helps Record Data with Light
In the new study, the scientists from ITMO University in Saint Petersburg, Leipzig University in Germany and Eindhoven University of Technology in the Netherlands could generate excitons at room temperature by changing the light parameters.
Chemists Create Molecular “Leaf” That Collects and Stores Solar Power Without Solar Panels
An international team of scientists led by Liang-shi Li at Indiana University has achieved a new milestone in the quest to recycle carbon dioxide in the Earth's atmosphere into carbon-neutral fuels and others materials.
