First light from the first high-energy superconducting undulator

(Phys.org)—More than eight years of effort by Advanced Photon Source (APS) physicists, engineers, and technicians culminated on Jan. 21, 2013, with the production of the first X-rays from the prototype of a novel superconducting ...

Large wave-vector phonon modes in silicon nanomembranes

(Phys.org) —Modified large wave-vector phonons in semiconductor membranes via hard X-ray thermal diffuse scattering (TDS) were observed that provide new insight into the fundamental thermal and electronic properties of ...

Ferroelectric oxides do the twist

(Phys.org) -- Some materials, by their nature, do what we want them to do -- notably, the ubiquitous, semiconducting silicon found in almost every electronic device. But sometimes, naturally occurring materials need a little ...

Scientists develop new AI method to create material 'fingerprints'

Like people, materials evolve over time. They also behave differently when they are stressed and relaxed. Scientists looking to measure the dynamics of how materials change have developed a new technique that leverages X-ray ...

Nanoparticles Cooperate to Detect and Treat Tumors

(PhysOrg.com) -- If one nanoparticle is good, two may be better, especially when they are designed to cooperate with each other to diagnose and treat cancer. That finding comes from work led by Michael Sailor, Ph.D., a member ...

3-D experiments shed new light on shape memory alloys

Shape memory alloys are well known for their remarkable properties—superelasticity, shape memory and actuation allow them to be crumpled up and then spring back to a "remembered" original shape.
