Flyash, a waste byproduct from coal burning, has been used effectively as a supplementary cementitious material (SCM) in Portland cement to displace a portion of the cement and lower the CO2 emissions associated with cement making. But because coal burning…
Sodium-ion batteries have many advantages over lithium-ion batteries due to sodium’s abundance and low cost. However, there are several performance challenges to overcome with sodium-ion batteries because there is typically a tradeoff between energy density and lifecycle. Now, a research…
Chemists from the Institute of Inorganic and Analytical Chemistry at the University of Freiburg (Germany; uni-freiburg.de) have synthesized a cationic, low-valence aluminum complex salt. “So far, there has been only one example of a cationic, low-valent aluminum compound, but it…
Last month at Achema 2022 (August 22–26; Frankfurt am Main, Germany), Q.ANT GmbH (Stuttgart, Germany; www.qant.de) introduced what is said to be the world’s first industrial-grade quantum sensor (photo) for particle analysis. By the use of super-fast software, electronics and…
An adaptable sintered filter element that is manufactured by 3D printing will be introduced this month at the Powtech exhibition (September 27–29; Nuremberg, Germany). Developed by Herding GmbH Filtertechnik (Amberg, Germany; www.herding.com), Omikron is an adaptable sinter-plate filter element that…
Aluminum alloy 7075 has excellent mechanical properties, including high strength for lightweighting applications, but its production process is energy intensive, which raises costs and limits its use. Now, scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) have developed…
A next-generation ethane-feed steam cracker designed by Lummus Technology (Houston; www.lummus.com) has the ability to achieve zero carbon dioxide emissions in the production of ethylene. The zero-CO2 design utilizes Lummus SRT pyrolysis furnaces and a state-of-the-art product-recovery system. Lummus improved…
Proton ceramic cells that couple endothermic steam reforming with heat from electrochemical gas separation and compression have been scaled up. These cells, developed by CoorsTek Membrane Sciences AS (Oslo; www.coorstek.com), the University of Oslo (both Norway; www.uio.no) and the Institute…
