In this video, Professor Mark Leemhuis shares how students at The Hague University of Applied Sciences are using the Filament Maker TWO to gain hands-on experience with shredding, drying, extruding, and even blending custom filament materials.
Simulations reveal how grains in metals and ceramics grow
An international team of scientists headed by Prof. Marco Salvalaglio from TUD–Dresden University of Technology in Germany discovered that internal stresses—not just interface energy—play a key role in shaping the microstructure of crystalline materials. These findings challenge classical theories and may improve how we design materials for engineering and technology.
Amatanweze confirms new methods to reduce steel defects
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 material with high-conductivity but slow thermal transfer
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.
Near-perfect defects in 2D material could serve as quantum bits
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.
