Method detects defects in 2D materials for future electronics, sensors

To further shrink electronic devices and to lower energy consumption, the semiconductor industry is interested in using 2D materials, but manufacturers need a quick and accurate method for detecting defects in these materials to determine if the material is suitable for device manufacture. Now a team of researchers has developed a technique to quickly and sensitively characterize defects in 2D materials.

What Will Happen to the Spitzer Space Telescope After It Is Retired?

Spitzer will be powered down this week. But what happens to the orbiting telescope now?

How to take a picture of a light pulse

Until now, complex experimental equipment was required to measure the shape of a light pulse. Now, it can be done in a tiny crystal with the size of less than a milimeter. This can be used to study new materials or even even to reliably and quickly detect diseases by examining tiny blood samples.

Discovery of a new liquid-liquid interfacial deformation by partial miscibility

The international collaborative team of Tokyo University of Agriculture and Technology (TUAT, Japan), IIT Ropar (India), Osaka Univ. (Japan) has discovered that "partially miscibility," in which two liquids do not mix completely with finite solubility, is capable of deforming the liquid-liquid interface. This interfacial deformation originates due to the spontaneous motion driven by phase separation between the soluble species, and is a phenomenon that cannot be seen with completely mixed (fully miscible) with infinite solubility or (almost) immiscible with no solubility.

Detection of very high frequency magnetic resonance could revolutionize electronics

A team of physicists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and enhance sensitivity.

Topological defects produce exotic mechanics in complex metamaterials

Metamaterials have properties that depend on their shape and architecture. Researchers at AMOLF, Leiden University and Tel Aviv University have found a new way of designing these metamaterials and their properties by deliberately incorporating small errors. They have published their results in Nature Physics.

The Argument Against High School Animal Dissections

Dissections, though a time-honored science class tradition, may actually be turning some students away from STEM.

Quantum computers offer another look at classic physics concepts

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven National Laboratory.

Waves of ice inside a droplet

A droplet falling on a surface that is considerably supercooled has been found to freeze in a way never observed before. Instead of the well-known growth of crystals, a colder surface results in moving circular ice fronts. These fronts move out of the center to the edge of the freezing drop. Scientists of the University of Twente and the Max Planck Center for Complex Fluid Dynamics have demonstrated this effect for the first time, and give an explanation for the physical mechanism involved in the latest Proceedings of the National Academy of Sciences.

Some Scientists Are Skeptical Dark Energy Even Exists — But Others Push Back

Some scientists have been poking at the foundations of dark energy, but many say the concept remains on solid, if mysterious, ground.
