The Joukowsky equation is often relied upon to determine the maximum possible fluid pressure inside a pipe, but there are certain scenarios where this equation does not return the expected conservative result for overpressurization We engineers love our formulas. Especially…
A new predictive analytics tool for heat-transfer-fluid (HTF) life expectancy uses artificial intelligence (AI) algorithms built around HTF sample analysis data. The tool, known as Fluid Genius, is designed to provide recommendations for extending fluid life and maintaining HTF systems.…
A catalytic process to selectively break carbon-carbon bonds within the polymer chains of polyethylene and polypropylene could allow the use of waste plastics to make biodegradable surfactant molecules. Researchers led by the Institute for Cooperative Upcycling of Plastics (iCOUP) at…
Although the oceans contain about 5,000 times more lithium than what is found on land, the low concentrations (about 0.2 parts per million (ppm)), as well as the predominance of other larger ions (sodium, magnesium and potassium) makes Li extraction…
