source:Nagoya Institute of TechnologyHeterogeneous catalysts speed up chemical reactions by being in a different state than the reactants. They are efficient and stable, even under challenging conditions such as high temperature or pressure. Traditionally, metals like iron, platinum, and palladium have been widely used in industries like petrochemicals and agriculture for important reactions such as hydrogenation and Haber's process.However, these metals are rare and can have problems like buildup from coking. Scientists are increasingly exploring common elements as catalysts for more sust...

Sex disparities in the association between rare earth elements exposure and genetic mutation frequencies in lung cancer patients source:Scientific ReportsThe ubiquitous use of rare earth elements (REEs) in modern living environments raised concern about their impact on human health. With the detrimental and beneficial effects of REEs reported by different studies, the genuine role of REEs in the human body remains a mystery. This study explored the association between REEs and genetic mutations in patients with lung adenocarcinoma (LUAD). A cohort of 53 LUAD patients underwent tumor DNA s...

source:Phys.orgAn international team of chemists has successfully created methylenedistibiranes, which are three-membered rings that have two antimony atoms and one carbon atom. In their paper published in the Journal of the American Chemical Society, the group describes how they were able to make the rings using just a three-step process.Methylenedistibiranes are generally used as intermediaries due to their ability to promote selective nucleophilic substitution, resulting in the creation of diantimonyl anions. Chemists have been wanting to be able to create them because it is difficult to us...
