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 ...

Key opportunities in the U.S. halogens market include optimizing domestic production and consumption, leveraging trade dynamics for strategic import/export, and identifying major producers, suppliers, ...

It is appropriate for us to contemplate the growth of understanding of chemical kinetics which has taken place since the time of Planck. Understanding starts with the recognition by Stark in 1908 of ...

I was looking at the periodic table of the elements the other day, as one does, when my eye fell upon the right-hand side of the chart. Right next to the noble gases at the extreme edge of the table ...

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.

When the alkali metals react with the different halogens (Group 7 of the periodic table), the group of compounds formed are known as the alkali metals halides. Due to the fact that there are a number ...

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 ...

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