Bauxite residue (red mud) is a byproduct from the smelting of aluminum. Like other waste slags from the metallurgy industry, bauxite residue is traditionally put into hazardous-waste landfills, although it contains a mixture of valuable raw materials in low concentrations.…
Granular activated carbon (GAC) can be used to remove polyfluoroalkyl substances (PFAS) from groundwater and drinking water, but current methods to regenerate spent GAC are costly and require high temperatures of greater than 1,000°C. A team of scientists at Battelle…
A collaborative research group in Japan has engineered a self-sustaining device that can detect the presence of COVID-19 particles or droplets in air. The device, which requires no batteries, employs a magnetostrictive clad plate composed of iron, cobalt and nickel,…
Spring-loaded pressure-relief valves (PRVs) often use bellows to ensure balanced operation. Data analysis from 30,000 PRV service records across different industries and valve brands shows a bellows failure rate between 2 to 6%, according to Emerson (St. Louis, Mo.; www.emerson.com).…
Microorganisms populate nearly any habitat, no matter how hostile it is. Their great variety of survival strategies is of huge potential in biotechnology. However, most of these organisms are unknown, because they cannot be cultivated. To make better use of…
