It's becoming increasingly rare to see halogen light bulbs. If you do encounter one, though, there's a very good reason to ...

Surface volatiles—chemical substances that easily become gases or fluids at relatively low temperatures and pressures—are transported into Earth through subduction zones, with some being transported ...

When it comes to energy-saving lightbulbs, LEDs and CFLs spring to mind. But what about halogen bulbs? They don't get much attention, partly because they've been around for a long time and they use a ...

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.

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 ...

As time wears on, it's becoming clear that the writing is on the wall when it comes to products and services that are destructive to the environment. It's taken a long time for governments to react, ...

A mineral found throughout subducting oceanic crust can shuttle fluorine and chlorine far deeper into Earth’s interior than previous models assumed. New experimental results show that phengite, a ...

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 ...
