An international team of climate scientists has used climate models to show that some very short-lived substances are partially to blame for ozone depletion over the tropics. In their paper published ...

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 ...

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 chondrites provides a firm reference composition, irrespective of ...

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 ...

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, ...

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 ...
