Zwitterions enhance ion transport for polymer-based electrolyte material
Batteries with solid-state electrolyte materials, rather than liquids or gels, are a goal of technology developers because of their advantages for battery safety, durability and reduced charge times. Certain ceramic-based electrolytes have shown the ability to transport ions quickly, but…
SaltX and Holcim confirm cement clinker production using new fully electrified process
Salt X Technology AB (Hägersten, Sweden) and Holcim (Zug, Switzerland) have, within the framework of their joint development collaboration, successfully and repeatedly produced Portland-quality cement clinker using a fully electrified, scalable process. Cement raw meal from Holcim was calcined at…
Learn how Enhanced Coriolis Control (ECC) helps you avoid common measuring errors
Enhanced Coriolis Control (ECC) mitigates the negative impact of high gas content in your measurement of liquids One of the most common reasons for measuring errors in Coriolis mass flowmeters is the measurement of liquids with significant gas…
Process for cellulose-derived pigments scales up to hundreds of tons/yr
A process for making pigments from cellulose for use in cosmetics, food and coatings applications has scaled up from a 1-ton/yr pilot unit to a process capable of generating multiple-hundreds of tons per year in a toll-manufacturing setting. The cellulose-derived…
PVC polymer chlorination with LEDs enhances resin stability
Lubrizol (Cleveland, Ohio; www.lubrizol.com) recently began producing chlorinated polyvinyl chloride (CPVC) resin in commercial reactors equipped with light-emitting diodes (LEDs) as the light source, instead of the conventional mercury lamps. The company’s LED reactor technology enhances the thermal stability of…
Low-temperature plasma process supports direct recycling of battery cathodes
Direct battery-recycling methods, such as re-lithiation — where depleted lithium is replenished directly onto cathodes via a solid-state reaction — hold many benefits over indirect methods, such as those relying on hydrometallurgy or pyrometallurgy, where cathodic structures are destroyed in…
Electrochemical-redox process expands recycling potential for LFP batteries
Lithium-iron-phosphate (LFP) batteries offer a compelling combination of performance characteristics for stationary energy storage, including improved safety and longevity, when compared to other lithium battery chemistries, such as nickel- and cobalt-based formulations. However, there are limited recycling pathways dedicated to…
Unique support boosts single-atom indium catalysis of CO2-to-methanol reaction
Synthesis of methanol from carbon dioxide is among the key goals for net-zero-CO2 production of chemicals and fuels. Previous investigation has suggested that indium oxide could serve as an effective catalyst for this reaction, but the structural details of the…
Gas-fed, solid-state electrolyzer could allow ethylene from waste-derived syngas
Conventional ethylene production via steam cracking of ethane or naphtha leads to the emission of 1 ton of CO2 for every ton of ethylene produced. Given the carbon intensity of the process and the annual volume of ethylene produced (300…
Rotating bioreactor scheme accelerates production of high-value products
A team of researchers at Iowa State University (ISU; Ames; www.iastate.edu) have developed a new bioreactor concept that streamlines production of value-added bioproducts at smaller scales by integrating three process steps (fermentation, product extraction and separation) into a single, compact…
