In a new paper submitted to Physical Review Letters and currently available on the arXiv preprint server, the LHCb collaboration reports the first dedicated measurement of the Z boson mass at the ...

This paper describes the synthesis and characterization of layered barium, calcium and strontium benzoates and evaluates the potential of these materials as catalysts in the synthesis of methyl ...

In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the mass of the sun), supermassive black holes (millions to billions of ...

Polycrystalline strontium-doped lanthanum manganite (LSM) powders with 0.15, 0.22, and 0.30 mol % Sr were synthesized by the polymeric precursor route using a molar ratio of 3:1 citric acid and metal ...

Scientists have created a groundbreaking map of strontium isotopes found across sub-Saharan Africa—which could help descendants of enslaved people reconstruct their family histories.

While genetic tests can reveal the ancestry of enslaved individuals, strontium analysis can now home in on where they actually grew up.

Molar Mass of Elements: Get here the concept of molar mass and the key differences between molar mass and percent composition, providing a clear understanding of their distinct roles and ...

Molar Pregnancy: Expert Explains Symptoms, Risk Factors, And Treatment Of This Rare Pregnancy Complication Molar pregnancy occurs when a fertilised egg does not develop normally.

Trace elements in a non-diseased tooth. Trace elements in a healthy feline's mandibular first molar tooth. Maps for barium (A), strontium (B), zinc (C), and lead (D) are shown. Relative concentrations ...

Female mass shooters are exceptionally rare, as experts say the average mass shooter is male and in his 20s.

Pairs of extremely cold strontium atoms have been used to make the most accurate molecular clock yet. It could be used to detect new forces and test some of Albert Einstein’s ideas about gravity.
