Researchers from Tokyo Metropolitan University have identified key similarities between the behavior of granular materials and melting gels. They found that falling beds of sand share the same destabilization mechanism as melting gelatin as it is heated from below, particularly how key parameters...

An international team of researchers led by Professor Min Seok Jang of KAIST and Professor Victor W. Brar of the University of Wisconsin-Madison has demonstrated a widely applicable methodology enabling a full 360° active phase modulation for metasurfaces while maintaining significant levels of...

Scientists have developed a low-cost microscopic imaging device small enough to fit on a smartphone camera lens, with the potential to make mobile medical diagnosis of diseases affordable and accessible....

A team of researchers working at the University of Chicago has found a way to use sound waves to model a system for rotational dynamics of inertial many-particle clustering. In their paper published in the journal Physical Review Letters, the group describes the model they created and possible uses...

Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. They are both compatible with modern electronics but also move speedily, thanks to their photonic...

Lawrence Livermore National Laboratory (LLNL) researchers have developed a new all-optical ultrasound technique capable of performing on-demand characterization of melt tracks and detecting formation of defects in a popular metal 3D printing process....

A camera usually requires a lens system to capture a focused image, and the lensed camera has been the dominant imaging solution for centuries. A lensed camera requires a complex lens system to achieve high-quality, bright, and aberration-free imaging. Recent decades have seen a surge in the demand...

Scientists have used a mathematical technique to design powerful magnets with straighter shapes for stellarator fusion facilities, allowing for easier manufacturing and maintenance. ...

In the search for novel types of superconductors -- phases of matter that that conduct electric current without loss -- scientists are investigating materials that consist of multiple layers. A team has studied in detail the properties of a system of three twisted graphene layers and gained...

Researchers say they've found a way to significantly increase the probability of observing the Unruh effect, a 'quantum glow' phenomenon that was first proposed in the 1970s. ...
