Selecting an effective system for controlling air pollution can help to achieve balance between environmental stewardship and industrial productivity Air pollution is an ongoing worldwide concern that impacts people and ecosystems across the globe. The emission of pollutants like particulate…
Researchers at Eidgenössische Technische Hochschule Zürich (ETH Zurich; Switzerland; www.ethz.ch) and Nanyang Technological University Singapore (NTU; www.ntu.edu.sg) developed a process to utilize industrial chicken feathers for making proton-conductive membranes that can be used in fuel cells, protonic transistors and water-splitting…
Substituting nitrogen atoms for aromatic carbon atoms at specific locations within the molecular skeleton of a possible therapeutic agent can have significant effects on molecular properties critical for biological activity, such as hydrogen bonding, polarity, metabolic stability, target specificity and…
A process to produce an alternative to palm oil for food applications, developed by scientists at Nanyang Technological University, Singapore (NTU Singapore; www.ntu.edu.sg), will be scaled up for commercial production through a partnership with Eves Energy Pte. Ltd. (Singapore; www.eves-energy.com).…
Now in its 27th year, the Green Chemistry Challenge Awards recognize and promote chemical technologies that reduce hazards to people and the environment by incorporating the principles of green chemistry into chemical design, manufacture and use. The program is sponsored…
Achieving regulatory compliance is often viewed as overly complicated or restrictive, but a good understanding of the current regulatory landscape can help fuel business growth and efficiency When talking about modern manufacturing, few sectors experience as much regulatory scrutiny as…
Metal components made with laser powder-bed fusion — an important additive manufacturing process — must be qualified for use in critical applications, but the qualification relies on expensive non-destructive evaluation (NDE) techniques. In-process monitoring offers a less expensive alternative, but…
A new ammonia-recovery plant has begun steady-state operation to demonstrate a patented process to upcycle the ammonia content from cattle manure into stabilized fertilizer ingredients. The Ammonia Recovery System (ARS) was developed by Bion Environmental Technologies, Inc. (Old Bethpage, N.Y.;…
Leather Tanning Trumpler GmbH & Co. KG (Worms, Germany; www.trumpler.com) and Archroma (Pratteln, Switzerland; www.archroma.com) have developed a new leather-production process that can be used to produce high-performance leather in a more eco-friendly and cost-efficient way. The new process, DyTan,…
Adhering to API 682 guidelines will create safe, efficient and effective mechanical-seal supports in pumping systems In the 1980s, mechanical seals became the most frequently used sealing technology in petroleum refineries and chemical plants. The American Petroleum Institute (API; Washington,…
