RO Membranes Toray Industries, Inc. (Tokyo, Japan; www.toray.com) has developed a highly durable reverse osmosis (RO) membrane that is said to offer double the resistance to cleaning chemicals of conventional counterparts. This reduces performance degradation from membrane wear and simplifies…
A next-generation membrane for durable fuel cells and electrolyzers
Hydrogen fuel cells and electrolyzers will be crucial technologies as the global energy transition progresses. However, both devices are often hampered by issues with durability and material costs — mainly associated with their membrane elements — which have slowed their…
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…
Business News: May 2024
Plant Watch Celanese expands production capacities for acetic acid and VAE April 9, 2024 — Celanese Corp. (Dallas, Tex.; www.celanese.com) started up a new production unit for vinyl acetate ethylene (VAE) in Nanjing, China and completed several downstream debottlenecking projects…
Evolving Demand and Feed Profiles Challenge Refiners
Trends related to the energy transition are shifting global demand for refined products and affecting feedstock slates, forcing petroleum refiners to embrace adaptation and flexibility Demand for fossil fuels has remained strong in the years after the COVID-19 pandemic, but…
Industrial Robots Forge Ahead
Performance improvements in robotics technologies for manufacturing and energy operations are leading to greater productivity, cost savings and safety improvements In the chemical process industries (CPI), mobile robots, often in conjunction with artificial intelligence (AI) and machine learning (ML), are…
Facts At Your Fingertips: Representing Particle Size and Geometry
Particle size and shape, as well as particle size distribution (PSD) are key determinants of bulk solids behavior [1–4]. A particle can be defined as a single unit of material having discrete physical boundaries that define its size. Particle science…
