When producing ultra-strong steel parts for vehicles, military gear, and heavy manufacturing, even minor cracks or distortions during heat treatment can cause significant delays and material waste. Dr. Kingsley Amatanweze, a recent Ph.D. graduate from the Missouri University of Science and Technology, has developed new methods to reduce these costly issues by improving the induction melting, pouring, and cooling processes of steel.
Thermoelectric materials like germanium telluride (GeTe) can convert waste heat into electricity, offering a promising energy solution. To better harness this potential, researchers used a novel “neutron camera” technique to study GeTe’s structure. They found that while GeTe maintains its overall crystalline form—essential for conducting electricity—it also exhibits dynamic disorder, where parts of the structure move and slow heat conduction. This unique combination enhances thermoelectric efficiency, making GeTe a strong candidate for advanced solid-state devices like heat pumps and generators. The study also resolved previous inconsistencies in structural measurements.
Scientists worldwide are striving to scale quantum technologies, which hinges on reliably generating qubits—the basic units of quantum information. One promising material for this is hexagonal boron nitride (h-BN), a two-dimensional substance known for hosting solid-state single-photon emitters (SPEs). These atomic structures can emit individual photons, making them strong candidates for building scalable quantum systems.
Chirality, or “handedness,” is a fundamental property where an object differs from its mirror image, seen across nature from molecules to DNA. In a breakthrough, Princeton University researchers have discovered a hidden chiral quantum state in a material previously believed to be non-chiral. This finding not only challenges existing assumptions in physics but also deepens our understanding of quantum phenomena, potentially opening new avenues in quantum research.
The comparison of the change in length, e.g. after hardening and tempering, is the next step in the model validation. The figure shows the comparison in the change in length of the cylinder. In the left part the change in length after hardening with nitrogen and additional tempering is shown; in the right part one […]
