Engineers copy snapping shrimp to produce underwater plasma

A team of mechanical engineers at Texas A&M University has found a way to generate plasma underwater by copying the snapping action of shrimp. In their paper published in the journal Science Advances, the group describes how they created a mechanical snapping shrimp claw in their lab and how well it worked.
Scientists have been able to create plasma underwater for some time-mostly by using electricity. Welding is done underwater using just such a technique. Lasers have also been used, but neither method is very efficient. In this new effort, the researchers sought to come up with a more efficient way to generate plasma underwater by mimicking the actions of the snapping shrimp.

SPX FLOW Launches Universal 2 ND Pump Series Designed Uniquely for Industrial Market

PR Newswire | January 29, 2024

SPX FLOW, has released the Universal® 2 ND Positive Displacement Pump (U2 ND) Series designed with industrial users in mind. The pumps offer the quality and durability the Waukesha Cherry-Burrell brand is known for while optimizing cost and suitability for the industrial market. The U2 ND series significantly expands the WCB pump range, aimed at enhancing reliability and performance across industrial applications while outperforming other pump styles, such as industrial lobe, gear or progressive cavity pumps.The design features improvements uniquely suited for industrial applications, including: Total cost of ownership: The pumps ensure a long running life, given their robust construction materials and designs tailored for each application. Because of its high volumetric efficiency, the pumps can be used to dose fluids, eliminating the need for an additional metering pump.  Efficiency: The U2 ND pump reduces slip, which occurs when fluids move backward from the liquid flow due to internal clearances. Lower slip means more efficiency, reducing the need for higher horsepower motors. Also, the series can process fluids over longer spans due to its high-pressure capability, which reduces the need for multiple pumps in these applications. Reliability: WCB is a proven and trusted global brand dating back to the 1880s. The pumps are made with durable, corrosive-resistant materials compatible with industrial environments. A robust design, equipped with industrial flanges or sanitary fittings, ensures manufacturers can choose the configuration to meet their needs.  Additionally, an extensive sales channel and domestic manufacturing footprint support this pump series, enabling quick deliveries on standardized parts across the entire Universal pump product line. The U2 ND series is complemented by the Universal Industrial 5000 series, which is tailored for users who require OEM (Original Equipment Manufacturer) seals for their industrial pumping operations. Julien Bassett, Pumps Global Product Manager: "Waukesha Cherry-Burrell has extensive experience offering pumps to customers built with their needs in mind. We wanted to expand our offerings to provide quality and durability of the SPX FLOW brand while catering to the unique needs of industrial manufacturers and their applications."
