1+ day, 9+ 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....

1+ day, 9+ 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…...

3+ day, 4+ hour ago   (396+ words) A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride - the electrically insulating counterpart to graphene, also known as "white graphene" - can be precisely controlled at the…...

4+ day, 7+ 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…...

6+ day, 8+ hour ago   (731+ words) Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make tradeoffs, providing signals that are strong but slow or fast but weak. The tradeoff between…...

1+ week, 3+ day ago   (614+ words) The U. S. Department of Energy Ames National Laboratory has been a leader in metal powder synthesis and metallurgy for more than 40 years. Now, Ames Lab is building on that expertise with a new refractory metal powder atomization system that will help…...

1+ week, 6+ day 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…...

2+ week, 1+ day ago   (244+ words) Thermo Fisher Scientific Inc., the world leader in serving science, today introduced the Thermo Scientific™ EMPAD™ G2 detector, a new detector designed to help researchers see and understand materials in unprecedented detail. EMPAD G2 enables high-speed four-dimensional scanning transmission electron microscopy (4D STEM),…...

2+ week, 4+ day ago   (316+ words) However, many known oxide perovskites are either insulating or have band gaps that are too large for effective solar energy conversion. The real challenge, therefore, is to identify compositions with moderate band gaps that could serve as light-absorbing materials. Conventional…...

2+ week, 6+ day ago   (156+ words) The stories of Nathalie Blanchard and Anne-Sophie Poulin-Girard carry a message that goes beyond professional achievement. Both are women who have built outstanding careers in a highly technical field – and both are actively working to open doors for the next…...
