Transcritical use of carbon dioxide refrigerant
Environmental regulations have curtailed the use of synthetic refrigerants, which has renewed interest in carbon dioxide as an alternative.
Chemical boundary engineering yields stronger steel
When applied to plain steels with carbon content of only up to 0.2 wt %, the method yields ultimate strength levels beyond 2.0 gigapascal and ductility exceeding 20%.
Astronaut urine can be used as an unlikely building material for space modules
Researchers from the Spanish Foundation for Science and Technology found the astronaut’s urine could be used as a building material for creating space modules for major space agencies on the moon
This plastic material is made to be recycled
The plastic can be disassembled into its constituent parts at the molecular level and then repeatedly reassembled into a different shape, texture and color without loss of performance or quality.
Designing solar cells for submerged service
Underwater solar cells have the potential to harvest power at depths up to 50 m in very clear waters with efficiencies of 55% to 65%.
Researchers combine starch, cellulose for biodegradable plastic
A research team from Osaka University in Japan has developed a bioplastic that degrades in seawater amid a growing plastic waste crisis impacting the world’s oceans.
Improved adsorption of metals from water by modified nanocarbons
The adsorption affinity of nanocarbons for metals is being magnified by a combination of amino group addition and solution plasma processing.
Team develops essential-oil based anti-bacterial film for hospitals
A plastic technology company has developed a plastic film impregnated with nano-capsules of essential oil for protecting hospital surfaces from microbe exposure.
Will 3D printing shift into high gear in the Covid-19 fight?
Governments have sought to enlist automakers, including Ford, General Motors, Ferrari and Nissan, to ramp up production of ventilators and other medical equipment that face shortages and are critical to saving lives.
Australia produces a medical radioisotope as a true theranostic agent
Scandium-47 has been produced in the Open Pool Australian Light-water Reactor as a beta-emitting radioisotope for targeted cancer therapy.
Opening plastic packaging may be contributing to microplastic pollution
Researchers from the University of Newcastle have conducted a study on how many microplastics are being generated from daily activities, like opening a bag or plastic bottle.
Nanoplastics found to persist in potable water
The health implications of nanoplastic ingestion via drinking water, estimated by the researchers as a few grams of plastic each month, are unknown.
