Classic double-slit experiment in a new light

An international research group has developed a new X-ray spectroscopy method based on the classical double-slit experiment to gain new insights into the physical properties of solids.

Enhanced NMR reveals chemical structures in a fraction of the time

MIT researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases.

Large Hadron Collider replacement plans unveiled – here's what it could discover

The Large Hadron Collider (LHC) at CERN is the most powerful particle accelerator in the world. During its ten years of operations it has led to remarkable discoveries, including the long sought-after Higgs boson. On January 15, an international team of physicists unveiled the concept design for a new particle accelerator that would dwarf the LHC.

In search of Weyl semimetals

Imagine how much you could accomplish if the circuits in your laptop and cell phone worked 10 times faster, and your battery lasted 10 times longer, than they do now.

New thermoelectric material delivers record performance

Taking advantage of recent advances in using theoretical calculations to predict the properties of new materials, researchers reported Thursday the discovery of a new class of half-Heusler thermoelectric compounds, including one with a record high figure of merit—a metric used to determine how efficiently a thermoelectric material can convert heat to electricity.

How molecules teeter in a laser field

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena. Now scientists report on an experiment where the dependence of the driven-dipole response on the bound state of an electron in a methyl iodine molecule is revealed.

Additive manufacturing reflects fundamental metallurgical principles to create materials

Engineers have been taking a novel approach to the development of engineering components produced using additive manufacturing.

Puzzling phenomenon in a quantum gas: Insulators with conducting edges

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists have now modeled what are known as topological insulators with the help of ultracold quantum gases. They now demonstrate how the edge states could be experimentally detected.

New light shed on intensely studied material

The organic polymer PEDOT is probably one of the world's most intensely studied materials. Despite this, researchers have now demonstrated that the material functions in a completely different manner than previously believed. The result has huge significance in many fields of application.
