The gigantic formations are surrounded by a 'graveyard of tectonic plates.'

Giant blobs that lurk near Earth's core are much older than scientists thought, new seismic data reveals.

MIT researchers fabricated 3D chips with alternating layers of semiconducting material grown directly on top of each other. The method eliminates thick silicon between layers, leading to better and faster computation, for applications like more efficient AI hardware.

Twenty years since its discovery, the journey to reach graphene's true potential is still underway

Barium strontium aluminum silicate (BaxSr1−xAl2Si2O8, BSAS) ceramics possess both phase stability and resistance to water vapor corrosion, making them ideal materials for radome technology and electronic packaging. To address the low tolerance of BSAS ceramics to damage and defects, the introduction of nano-reinforcements is an effective approach to enhance their strength and toughness.

Alloying is a key process in creating new materials. By combining metals with desirable traits, scientists can produce alloys with suitable properties. For example, stainless steel, formed by combining iron with chromium, nickel, and other elements in smaller quantities is highly resistant to corrosion.

Our ongoing endeavor to venture into outer space demands substantial technological advances across various fields, including materials science. Materials used in the aerospace industry must be lightweight yet mechanically resistant, a combination that is difficult to achieve. Fortunately, metal matrix composites have come a long way since their inception in the twentieth century, and many experts believe that they…

Electronic devices run on the fundamental property that electrons' charge helps them to move and generate current. Now imagine another property—this one in the quantum realm—that can help electrons behave more energy-efficiently. Spintronics makes use of the spin of an electron, a fundamental property dependent on its intrinsic angular momentum.

Researchers have developed a new design for computer memory that could both greatly improve performance and reduce the energy demands of internet and communications technologies, which are predicted to consume nearly a third of global electricity within the next ten years.

Multi-wavelength femtosecond pulses with flexible tunability in both the temporal and spectral domains have been widely desired, owing to their potential applications in controlling strong field ionization, electron dynamics, and high-order harmonic generation. Particularly, ultrafast pulses coherently synthesized by multiple spectral bands are thought to be an ingenious instrument to harness or enhance…

Thermoelectric materials, substances that convert temperature difference into electricity, find a multitude of applications involving the conversion of waste heat into useful electrical energy. However, they often need to rely on heavy rare earth elements for efficient thermoelectric conversion.

Magnesium diboride (MgB2) is a low-cost, non-toxic superconductor used in field magnets, electric motors, and generators. However, producing nanoscale boron (B) particles to fabricate MgB2 is expensive. Researchers recently tackled this issue by using high-energy ultra-sonication in 2-propanol, a highly viscous solvent, to produce impurity-free, nm-sized B particles. The approach is cost-effective and enables…

Today, electronic and photonic devices are ubiquitous in smart phones, computers, light sources, sensors, and communications. To underpin the demand for optoelectronic applications, functional materials are essential. For instance, silicon is required for logic computing and photonic integrated circuits (PIC); group III-V semiconductors (such as GaAs, InP, AlN, etc.) are used for optoelectronic, light-emitting and…

The authors develop a new oxide-dispersion-strengthened NiCoCr-based alloy using a model-driven alloy design approach and laser-based additive manufacturing, showing how such designs can provide superior compositions using far fewer resources than previous methods.

A probe on Mercury used for the purpose of "surface-space-environment-geochemistry-and-ranging" abbreviated as the MESSENGER mission to Mercury, resulted in the discovery of geological structures known as hollows. Such landforms are quintessentially extraterrestrial with no close counterpart on the airless silicate bodies. Astrogeologists had used multispectral images and geochemical measurements via probes to show…

Publishing in the International Journal of Extreme Manufacturing , researchers from Harbin Institute of Technology, Huazhong University of Science and Technology, Guizhou University and Ruhr-University Bochum present a brief review on the application of numerical simulations in addressing the impact of properties and microstructures of workpiece materials on the diamond cutting mechanisms of different types of…
