The complicated path toward sustainable metalworking fluids
Achieving sustainability requires clarifying what sustainability entails and balancing incompatible priorities to make products that work for specific customers and their applications.

A more detailed view of the composition of the sulfurized polymer hybrid network demonstrates how the bonding among atoms may change during a charge, discharge cycle. TECH BEAT I 

Higher performing lithium-sulfur batteries
A new approach has been developed to minimize solubilization of polysulfide intermediates, which leads to the creation of a lithium-sulfur battery with high capacity and excellent cycling stability.

opper is used as a substrate for rhodium (small particles on the catalyst surface), which enables this antenna photocatalyst to convert methane and water to hydrogen. An image in the right-hand corner of the figure displays the conversion to hydrogen.TECH BEAT II 

Emissions-free steam methane reforming process
Researchers have found the right catalyst combination to utilize plasmonic photocatalysis to form hydrogen in a more efficient manner than using conventional steam methane reforming.

A new approach has been developed to produce sustainable aviation fuels (SAFs) through arrested methanogenesis and SAF catalytic upgrading. TECH BEAT III

Sustainable aviation fuel from wastewater
Researchers have used high-strength wastewater as the raw material to produce volatile fatty acids that are then ultimately converted into hydrocarbons.
