Controlling Process Variables for Solid-State Battery Performance

Optimizing electrical conductivity in next-generation batteries depends on carefully controlling process variables, such as mixing, particle-size distribution and temperature. Presented here is a discussion of how these process variables affect battery performance In the evolving landscape of energy storage technologies,…

Automation Optimizes Rinsewater Recycling

Onsite recycling proved cost-effective for an aerospace supplier. With real-time feedback and control, a new automation upgrade takes process efficiency to the next level Throughout the chemical process industries (CPI), efficient and affordable approaches to wastewater treatment are of paramount…

Advancing battery technologies

Last month, the U.S. Department of Energy (DOE, www.energy.gov) announced that two Energy Innovation Hub teams would receive a total of $125 million ($62.5 million to each team) in funding over five years to “seed and accelerate next-generation technologies beyond…

A low-cost coating system designed to optimize water electrolysis

Seemingly small component changes can make a large impact on the productivity of electrochemistry systems, such as electrolyzers used for producing “green” hydrogen. For example, a new coating technology developed by Oxford nanoSystems Ltd. (OnS; Abingdon, U.K.; www.oxfordnanosystems.com), when applied…

Recyclable wind turbine blades

As wind energy takes a prominent role in the energy transition, researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL: www.nrel.gov) have focused on manufacturing sustainable turbine blades that can be made from bio-derivable resources and then…

Process for continuous production of MOFs plans scaleup

Metal-organic frameworks (MOFs) have shown great potential for a number of applications, including as carbon-capture materials, but their use commercially has been limited by production methods, which are generally expensive batch processes. With the development of a continuous process for…

Recycling mixed medical waste with steam cracking

Currently, medical waste streams are complicated to recycle because these single-use products — such as facemasks, syringes, nitrile gloves and non-woven gowns — consist of multiple materials and must be considered contaminated with potentially infectious particles. Now, researchers at Chalmers…
