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…

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…

Recovering lithium with thermal-swing liquid-liquid deionization

Much of the planet’s lithium is contained in brine, but the concentration is often quite low, making it difficult to efficiently extract lithium — typical extraction technologies may only demonstrate 30–60% yield. Adionics (Les Ulis, France; www.adionics.com) has developed a…

Chementator Briefs

CO2 liquefaction Last month, Linde Engineering (Pullach, Germany; www.linde-engineering.com) signed a contract with Yara International ASA (Oslo, Norway; www.yara.com) to build a world-scale carbon dioxide liquefaction plant in Sluiskil, the Netherlands. The Sluiskil project forms a key part of Yara’s…

Completely recycled viscose for the first time

Researchers at Lund University (Sweden; www.lth.se) have succeeded in converting worn-out cotton sheets into new viscose fibers using a process that — for the first time — enables all of the viscose to be recycled. Current recycling methods often require…

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…
