Quantum chemical investigations into halogen compounds subject to relativistic effects have advanced understanding of bonding, reactivity and spectroscopic properties across the periodic table. As ...

LESSON OBJECTIVE: Describe certain reactions of halides and halogens and state some uses of halogens and their compounds. In this lesson we some reactions of the Halogens, the concept of ...

It was observed by C. W. Rice in 1944 that the emission of positive ions from a platinum anode heated in air is increased very markedly when vapours of compounds containing halogens such as carbon ...

Catalysts are essential for the chemical industry because they accelerate reactions and increase their yields. However, many of today's catalysts are based on expensive and environmentally harmful ...

An international team of chemists and climate scientists, has conducted an assessment of the impact of short-lived halogens (SLHs) on Earth's atmosphere and are suggesting that their findings indicate ...

Rationale: Accurate hydrogen isotopic analysis of halogen- and sulfur-bearing organics has not been possible with traditional high-temperature conversion (HTC) because the formation of ...

THE FIRST DIRECT atmospheric measurements of iodine oxide and bromine oxide above the Antarctic snowpack unexpectedly indicate that the chemicals participate in destroying ozone and change the ...
