Engineers reveal reversible superglue inspired by snail mucus

Snails secrete a mucus that acts like superglue, allowing them to adhere to rough surfaces like rocks.

Inspired by this aspect of snail biology, scientists at the University of Pennsylvania, Lehigh University and the Korea Institute of Science and Technology have created a superglue-like material that is “intrinsically reversible.” In other words, it can easily come unglued.

Frangopol awarded 2019 George W. Housner Structural Control and Monitoring Medal

George W. Houser is widely considered the father of seismic engineering, which ushered in safer, more cost-effective construction in earthquake-prone areas.

So it’s fitting that a medal bearing his name would be bestowed on a researcher who’s played a similarly foundational role in ensuring the reliability of modern civil infrastructure systems.  

WATCH: The Rotating Wheel Rayleigh Taylor Instability Experiment

Arindam Banerjee, an associate professor of mechanical engineering and mechanics, and his students developed the Rotating Wheel Rayleigh Taylor Instability Experiment, which studies two-fluid mixing to mimic inertial confinement fusion. The lab, known as the Turbulent Mixing Laboratory, took Lehigh students five years to build from scratch. Watch the video in the Lehigh University News Center.

Researchers reveal 'instability threshold' of elastic-plastic material using mayonnaise

Arindam Banerjee, an associate professor of mechanical engineering and mechanics, studies the dynamics of materials in extreme environments. He and his team have built several devices to effectively investigate the dynamics of fluids and other materials under the influence of high acceleration and centrifugal force.

One area of interest is Rayleigh-Taylor instability, which occurs between materials of different densities when the density and pressure gradients are in opposite directions, creating an unstable stratification.

Martin Takáč awarded the 2019 Richard P. Vinci Award for Educational Excellence

ISE Assistant Professor Martin Takáč was named the recipient of the PC Rossin College of Engineering and Applied Science’s 2019 Richard P. Vinci Award for Educational Excellence. This award recognizes a Rossin College faculty member who has demonstrated effective teaching and/or enhanced the student learning experience by introducing innovative teaching methods into the classroom and shows an outstanding commitment to the success of their students. The award is named for the late Richard P. Vinci, professor of Materials Science and Engineering.
