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,…
BTX extraction A newly launched series of blended solvents for the extraction of benzene, toluene and xylenes (BTX) from a variety of feeds shows improved performance over single solvents, while avoiding environmentally problematic solvent components. The series, known as BTX…
The MT100 Series multipoint mass flowmeter (photo) provides air-gas flow measurements to help optimize boiler performance and reduce fuel consumption and greenhouse-gas emissions. These devices feature compact thermal-dispersion flow-sensor technology. They accurately monitor and report the flowrate or the totalized…
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).…
Designed with efficiency and mobility in mind, the Model HSM-405SC-25 inline high-shear mixer (photo) features the Solids/Liquid Injection Manifold (SLIM) technology. The SLIM technology is a unique rotor-stator device capable of injecting powders directly into a fast-moving liquid stream without…
Developed by researchers at the Massachusetts Institute of Technology (MIT; Cambridge, Mass.; www.mit.edu), these durable, flexible solar cells are glued to a strong, lightweight fabric, making them easy to install on a fixed surface. They are one-hundredth the weight of…
This past year was one of the best in a decade for the chemical process industries (CPI), according to the American Chemistry Council’s (ACC; Washington, D.C., www.americanchemistry.com) year-end report [ 1]. The report details that output of U.S. chemical producers…
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.…
Scientists from Nanyang Technological University, Singapore (NTU Singapore; www.ntu.edu.sg) have developed a technique to convert waste paper, from single-use packaging, bags and cardboard boxes, into electrodes, which can be made into rechargeable batteries that power mobile phones, medical equipment and…
The SpillGuard leak-recognition system (photo) instantly alerts users when a leak is detected. This FM-approved technology is placed within the sump of a spill-containment device, or near the equipment to be monitored, and alerts users with an audible and visual…
