Russian research team reveals submicroscopic pore structure of chernozem using ion beam scanning electron microscopy

Researchers at the Moscow Institute of Physics and Technology and their collaborators have recently used focused ion beam scanning electron microscopy (FIB-SEM) to perform detailed characterization of the microstructure of chernozem soil samples. The study shows that this technique can identify pores smaller than 1 micron, pore morphology, and specific organic components in soil, providing a new observational tool for understanding the mechanisms of chernozem fertility formation and maintenance. The research was supported by a grant from the Russian Science Foundation and published in the 17th series "Soil Science" of the Moscow University Bulletin. Soil science research typically requires extending from the field scale to the microscopic scale. Computed tomography (CT) has been widely used to...

U.S. Team Traces Source of Anomalous Gamma Rays from Zinc-70, Nuclear Magnetic Transitions May Improve Models of Heavy Element Formation

An international research team led by scientists from the Facility for Rare Isotope Beams (FRIB) at Michigan State University has recently identified the source of the large number of low-energy gamma rays emitted by zinc-70 nuclei. The study suggests that magnetic transitions occurring within the nucleus are the key reason for this anomalous signal enhancement. The findings were published in the journal Nature under the title "Magnetic character of the low-energy enhancement in 70Zn." Gamma rays are electromagnetic radiation released when excited atomic nuclei transition to lower, more stable energy levels. For a long time, scientists have observed an anomalous increase in the number of low-energy gamma rays in some atomic nuclei, known as the low-energy enhancement (LEE), but its physical mechanism had remained unclear...

ANSTO Australia Develops New Solution for Immobilizing Sulfate-Bearing Radioactive Waste

The Australian Nuclear Science and Technology Organisation (ANSTO) announced on July 31, 2026, that its researchers have developed a new waste treatment material for immobilizing sulfate-bearing radioactive waste, which is expected to solve the technical challenges in the long-term management of such waste and provide a reference pathway for similar radioactive waste treatment internationally. The related research has been published in the Journal of the European Ceramic Society. The study demonstrates for the first time the application of Hot Isostatic Pressing (HIP) technology in consolidating a dedicated glass-ceramic waste form for sulfate-rich nuclear waste. The research originated from ANSTO's need to manage waste generated during the production of medical radioisotopes, among which sulfate-bearing liquid waste...
