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 ...

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.

How many halogens, that is volatile elements such as chlorine and fluorine, are present on the Moon and how they are distributed provides vital insights into the origin and evolution of our celestial ...

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 ...

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

Last month, halogen lightbulbs went out all over Europe. Following a general ban by the European Union, the sale and purchase of halogen bulbs is being gradually phased out. Retailers will be allowed ...

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 ...

LED headlights are all the rage in the auto industry these days and now are available on many lower-priced vehicles, though usually only on higher trim levels and often as optional equipment. Related: ...

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 ...
