With fuzzy nanoparticles, researchers reveal a way to design tougher ballistic materials

Mon, 12/13/2021 - 23:22
Researchers have discovered a new method to improve the toughness of materials that could lead to stronger versions of body armor, bulletproof glass and other ballistic equipment. The team produced films composed of nanometer-scale ceramic particles decorated with polymer strands (resembling fuzzy orbs) and made them targets in miniature impact tests that showed off the material's enhanced toughness. Further tests unveiled a unique property not shared by typical polymer-based materials that allowed the films to dissipate energy from impacts rapidly.

Some polycrystal grain boundaries feel the heat more than others

Thu, 12/02/2021 - 19:21
Researchers have used electron energy loss spectroscopy to directly measure the coefficient of thermal expansion at grain boundaries in the polycrystalline material SrTiO3. The researchers identified differences in the coefficient of expansion depending on the grain boundary. In addition to revealing the thermal properties of SrTiO3, the findings demonstrate the potential of EELS for probing materials for a wide range of industries.

Shrinking qubits for quantum computing with atom-thin materials

Wed, 12/01/2021 - 02:39
Current approaches to create superconducting qubits for quantum computers yield chips that are substantially larger than those found in classical computers. To shrink things down, researchers have taken advantage of atomically thin, 2D materials to construct the necessary capacitors for superconducting qubits. Their two-qubit chip is 1,000x smaller than those made with conventional fabrication techniques.
