Storing and processing anhydrous hydrogen chloride as an ionic liquid
Hydrogen chloride is an important byproduct of the chemical industry, with over 9-million ton/yr generated by industrial chlorination processes, such as the production of chloromethanes and polymers (polyurethanes and polycarbonates). Although HCl can be easily recovered by gas scrubbing with…
Electrochemical sensor selectively detects dangerous bacteria
Researchers at Goethe University Frankfurt (www.uni-frankfurt.de) and Kiel University (both Germany; www.uni-kiel.de) have developed a new sensor for the detection of bacteria. It is based on a chip with a surface coating that ensures only very specific microorganisms, such as…
Improving sodium-ion batteries with nanocellular graphene
Nanocellular graphene (NCG) is a specialized form of graphene that achieves a large specific surface area by stacking multiple layers of graphene and controlling its internal structure with a nanoscale cellular morphology. Although the material has the potential to improve…
Solid-state synthesis simplifies cathode manufacture
The production and processing of cathode active materials (CAM) are among the largest contributors to the cost of lithium-ion battery manufacturing. Typical CAM manufacture involves multiple, multi-phase steps in a co-precipitation process that requires a large amount of water and…
Carbon-fiber-reinforced polymer boosts interfacial adhesion and recyclability
The high strength-to-weight ratio and robust mechanical properties of carbon-fiber-reinforced polymers (CFRPs) make them attractive for use in wind-power turbine blades, automobile components, and in airplanes and spacecraft. However, challenges — such as weak interfacial adhesion and poor recyclability —…
A control room with generative-AI capabilities
In January, specialty materials maker Celanese Corp. (Irving, Tex.; www.celanese.com) beta-launched a remote-operations control room (ROCR) that allows hands-free queries of plant data for faster data gathering and decision-making. The ROCR leverages recent advances in generative-artificial intelligence (gen-AI)-powered natural language…
Another step forward for new technologies for ammonia synthesis
In late February, Yokogawa Electric Corp. (Tokyo; www.yokogawa.com) announced that it has invested in and signed a memorandum on a business partnership with Tsubame BHB Co., Ltd. (Yokohama, Japan; tsubame-bhb.co.jp). Yokogawa is the latest to partner with Tsubame BHB, joining…
Membrane-free water electrolysis
Researchers at KTH Royal Institute of Technology (Stockholm, Sweden; www.kth.se) have developed a way to decouple the production of hydrogen and oxygen in water electrolysis, thereby reducing the explosion potential of mixing the two gases. The method, described in a…
This cooling and water-harvesting system requires no heat
A novel technology for cooling and dehumidification is nearing commercialization through several strategic partnerships, including GE Vernova, BASF and Carrier Global. Montana Technologies’ (Ronan, Mont.; www.mt.energy) AirJoule technology employs a metal-organic-framework (MOF) desiccant material that exhibits higher water-uptake capacity and…
A new super-duplex tube tailored for acids
Last month at the AMPP Annual Conference + Expo 2024 (New Orleans, La.; March 3–7), Alleima AB (Sandviken, Sweden; www.alleima.com) introduced SAF 3006 (UNS S83071), a high-alloy duplex (austenitic-ferritic) stainless steel tailored to enhance corrosion resistance in acidic and caustic…
