Scientific research has shown that the radiation frequency of rubidium and cesium can remain stable over long periods of time. Atomic clocks produced using rubidium atomic frequency standards utilize transitions between ground state hyperfine energy levels, resulting in advantages such as small size... Read More

High-purity iron refers to iron with a purity exceeding 99.9%. Iron-based materials developed using high-purity iron as raw material have superior properties compared to traditional iron-based materials, such as lower ductile-brittle transition temperature and recrystallization temperature, improved ...

Due to their unique layered structure and low phonon energy of approximately 500 cm−1, rare earth oxysulfides exhibit extremely high melting points (typically 2000-2200°C) and a narrow bandgap (approximately 4.6-4.8eV). This gives them high chemical and thermal stability, making them frequently used ... Read More

Gadolinium contrast agents are currently the most widely used magnetic resonance imaging contrast agents in clinical practice. Gadobutrol, as a second-generation gadolinium contrast agent, is an extracellularly distributed, non-tissue-specific, non-ionic, macrocyclic paramagnetic gadolinium chelator... Read More

With the increasing demand for economic efficiency in power plants, modern advanced reactors are developing towards large fuel loads, high burnup, and long cycles. This increase in initial fuel load significantly increases the initial residual reactivity of the reactor core within the active zone. ... Read More

The atomic radius of rare earth is generally between 0.1821 and 0.2042 nm, while the atomic radius of iron is 0.1241 nm. The difference between the two is large, so the solid solubility of rare earth in steel is generally very low. A large number of studies have shown that the addition of trace rare ... Read More
