Modernized pumps and advanced controls improve accuracy and repeatability of liquid-dosing systems Whether the application is dosing chemicals for process or water treatment, whether it’s batch or inline dosing and whether it’s continuous or intermittent flow, at its heart, successful…
A team from RMIT University (Melbourne, Australia; www.rmit.edu.au) and the National Institute of Technology, Warangal (Warangal, India; www.nitw.ac.in) has developed a cost-effective and eco-friendly way of producing graphene using a eucalyptus polyphenol solution extracted from eucalyptus bark. RMIT’s professor Suresh…
Nanofiltration Toray Industries, Inc. (Tokyo, Japan; www.toray.com) has created what is claimed to be the world’s highest-level nanofiltration membrane. The new membrane triples the permeation performance of conventional models while enhancing ion and organic-compound separation from aqueous solutions. In developing…
Scientists have long sought ways to take advantage of the high strength of natural silk protein in new materials, but its incorporation has been hindered by the inability to stabilize the protein in water. Now, a company known as Evolved…
Plant Watch Ineos breaks ground for Bayport ASA plant August 12, 2019 — Ineos Styrolution GmbH (Frankfurt, Germany; www.ineos-styrolution.com) hosted a groundbreaking ceremony for its new acrylonitrile styrene acrylate (ASA) plant in Bayport, Tex. The new site, which is designed…
Although it contains many valuable metals, electronic waste (e-waste) is an exceedingly difficult material stream to process, and the vast majority of e-waste is not recycled. EnviroLeach Technologies Inc. (Vancouver, B.C.; www.enviroleach.com) is currently preparing to start up a first-of-its-kind…
Oxysulfide semiconductors have narrow bandgaps — a property that makes them suitable photocatalysts for water splitting under irradiation with visible light (640 nm wavelength). That’s because the electronegative sulfide ions negatively shift the valence band edges of the corresponding oxides.…
Many countries are now making rapid advances in hydrogen energy technologies and strategy, and the rest of the world has much to learn from their experience, according to a new report — Advancing Hydrogen — compiled by a team from…
The seemingly boundless versatility of additive manufacturing makes it an area ripe for fast evolution, but critical industrial applications also demand verification and reliability There is no doubt that 3D printing (also known industrially as additive manufacturing; AM) has set…
Microplastics — a subgroup of plastics with an effective diameter less than 5 mm — are ubiquitous pollutants. They adsorb organic and metal pollutants that are ingested by aquatic organisms, and accumulated all the way up the food chain. Using…
