Electrons play many roles in solid materials. When they are weakly bound and able to travel—i.e., mobile—they can enable ...

This paper is concerned with the hydrostatic extrusion of mono-core, bronze-process superconductor billets. The thermo-mechanical, elasto-plastic finite-element method is used to analyze the extrusion ...

Bulk rhombohedral Bi at ambient pressure is a well-known semimetal, and its transition to a superconductor has not been observed, at least down to 50 mK. We report that, unlike bulk rhombohedral Bi, ...

The design of metal-bearing carbon-based materials with unique structures and intriguing properties is highly desirable in the fields of physics, chemistry, and materials science. Here, within ...

Superconducting radio frequency (SRF)-cavities in the field of particle accelerators are mostly manufactured from bulk or sheet niobium (Nb). Complex shapes of SRF-components like high order ...

The aim of this work is to study the elastic behavior of some Ti-Nb-Zr alloys (Ti-8Nb-13Zr, Ti-13Nb-13Zr, Ti-18Nb-13Zr and Ti-41.1Nb-7.1Zr) developed to biomedical applications. These alloys were ...

President Trump said the U.S. and China had reached a deal to save their trade truce in a post on his Truth Social platform. Photo: Tom Williams/CQ Roll Call/ZUMA Press China’s chokehold on ...
