New experiments on thallium decay have helped determine the Sun formed over 10–20 million years, improving stellar nucleosynthesis models. Have you ever wondered how long it took our Sun to form in ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) say that they have built a thulium fiber laser capable of emitting 1.91 kW - nearly double the typical output ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have developed powerful thulium fiber laser systems that almost double the previous performance world record.

The Ecology and Environment Department of Hunan in Central China issued on Tuesday a notice on the emergency treatment of abnormal thallium concentrations in the Chenzhou-Leiyang section of the ...

OSAKA--Thallium was detected in the comatose aunt of a man detained on suspicion of using the highly toxic substance to kill a female acquaintance, police said. Just 1 gram of thallium is enough ...

HITHERTO it has seemed that thallium was the only heavy metal with but slight tendency to form water-insoluble normal and inner-complex salts with organic compounds of acid character. Monovalent ...

Mar. 25, 2025 — Researchers have determined that six gas valves provide the best protection against plasma disruptions in SPARC, a next-generation, experimental fusion system. By refining the ...

An atomic number – the number of protons in the nucleus of an atom of the element. These rules help in identifying and ...

These rules help in identifying and writing chemical symbols consistently across all elements. The symbol serves as a shorthand notation for each element's name in formulas and equations, making ...

A comprehensive numerical model based on solving rate equations of a thulium-doped silica-based fiber amplifier is evaluated. The pump power and thulium-doped fiber (TDF) length for single-pass ...

Nuclear physics is the study of the protons and neutrons at the centre of an atom and the interactions that hold them together in a space just a few femtometres (10-15 metres) across. Example ...
