Figure 1: Br/Cl and I/Cl for chondrites and planetary materials. Figure 3: CI-chondrite and Mg-normalized BSE abundances as a function of 50% T C. The limited variation in the Br/Cl and I/Cl ratio of ...

New research shows that using halogens -- a class of elements that include fluoride, bromine, chlorine and iodine -- in a dye-sensitized solar cell can increase conversion efficiency by 25 per cent.

The technique avoids toxic byproducts from conventional halogen gases, cutting environmental impact while advancing ...

The distribution of halogens like chlorine reveals much about the formation of the lunar crust. An international research team has now shown in laboratory experiments that rocks with surprisingly high ...

Electronics companies have experienced some chemical reactions in the past two decades. Many will recall the European RoHS Directive (Restriction of Hazardous Substances), which came into force in ...

Part of Chemistry (Single Science) Atomic structure and the periodic table ...

Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride.

Halogenated flame retardants, while not yet banned in the United States, are definitely on their way out. Clariant Masterbatches has come up with three nonhalogenated ...

I’ve been highly critical of “greenwashing” in this space where companies make environmental claims for their products that are often half-baked. I came across an effort today by Herman Miller, ...
