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…
The Mobile Minor MM 100 spray dryer (photo) is equipped with the Cyclone CEE mechanical powder separator. This cyclone helps operators overcome challenges in spray drying, such as smearing due to powder settling in the cyclone, as well as abrasion…

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,…
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).…
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…
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…
This company’s new HollowStream liquid atomizing spray nozzle (photo) provides a hollow-cone spray pattern, and features a tangential flow design. The design is vaneless, with wide-open internal features, to resist clogging while producing a uniform distribution in a ring pattern…
In recent years, engineers at ETH Zurich have developed technology to produce liquid fuels from sunlight and air. At the heart of the production process is a solar reactor that is exposed to concentrated sunlight delivered by a parabolic mirror…
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.;…
