Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding ...

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: Reyhaneh Farimani, University of ...

Complex fluids, such as polymer melts and concentrated suspensions, are foundational materials for industrial products, including high-strength plastics and optical components. The final performance ...

Van Gogh's "The Starry Night" accurately depicts the energy distribution in turbulent flows. The painting's swirls follow Kolmogorov's law of turbulence, a key equation in physics. It also shows ...

With a myriad of health effects, thyme extract may seem like a magic medicinal ingredient. Its biologically active ...

Stewart McCorkle Faculty Fellow Brett G. Compton coauthored a comprehensive review on the physics of direct-ink writing (DIW), a highly versatile type of 3D printing, which was published on January ...

Researchers at Penn, led by Physics and Astronomy professor Arnold Mathijssen, have discovered ways to achieve quality coffee extraction using fewer beans. Published in “Physics of Fluids,” the ...

Using unconventional statistical mechanics to understand fluid dynamics, a professor helped solve a 150 year old physics problem of how turbulent fluids move through a pipe. In 1883 Osborne Reynolds ...
