2+ day, 8+ hour ago   (682+ words) Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall off....

2+ day, 8+ hour ago   (393+ words) "Nuclear reactors are designed to operate for several decades, but we cannot wait that long to understand how materials will hold up in extreme nuclear environments," said Mehmet Topsakal, a materials scientist in the Nuclear Science and Security Department at…...

4+ day, 10+ hour ago   (907+ words) Engineering plastics can appear rigid and reliable in short tests yet continue to change for years under load, making stress, temperature, molecular structure, reinforcement, and predictive modeling central to whether a component retains its shape, strength, and function. The tensile…...

5+ day, 6+ hour ago   (331+ words) High-entropy alloys are highly promising structural and functional materials. Among them, refractory high-entropy alloys possess outstanding high-temperature mechanical properties and have broad application prospects in critical components under extreme working conditions such as aerospace, nuclear power, and gas turbines. Chinese…...

2+ week, 8+ hour ago   (162+ words) It's challenging for scientists to monitor chemical processes at nuclear facilities in real time. In this study, scientists developed new techniques to analyze chemical solutions in complex environments. The. These models draw information about chemical systems from real-life data. The…...

3+ week, 13+ hour ago   (256+ words) The study examines whether elemental mixing can produce neutronic cocktail effects. These effects occur when a material’s neutron-attenuation behavior differs from that expected from its individual elements. The effect is particularly important in nuclear systems, where controlling neutron transport is…...
