the chemical industry. Ruthenium compounds can be used in solar cells to turn light energy to electrical energy due to their ability to absorb light throughout the visible spectrum. It is also one of the most efficient hardeners of platinum and palladium. It is alloyed with these metals to make electrical contacts for severe wear resistance and some jewelry. These alloys are also used to improve the corrosion resistance in titanium. It is a versatile catalyst used to remove H2S from oil refineries

The lake’s liquid is bright yellow and somehow glittering. The scent is seducing; mildly bittersweet with a hint of barley‚ malt and hops. Carlo is tranced as he walks slowly towards the lake. The water’s level is at his waist; he slowly lowers his head ‚ sipping a bit. Carlo likes it. Carlo likes it a lot! The sweet earthy herbal taste gradually elicits ecstacy. The brew is thick‚ rich‚ with floral and grapefruit notes. He can sense a slight sourness and mysterious enchanting undertone

Five fun facts about is one‚ Ruthenium was founded in 1844 by Karl Ernst Claus. Also‚ the metal is used as a hardener for palladium and platinum and Ruthenium is a member of the platinum group. And when pure Ruthenium alone can cost $1400 per 100g. Ruthenium is considered a rare metal and is very hard to find.

One is called catalytic hydrogenation which can be used to reduce pi bonds in many functional groups. This is achieved by adding dihydrogen along with a metal catalyst (e.g. Nickel‚ platinum‚ palladium‚ or rhodium) to a compound with a double or triple bond. The metal catalysts have different properties and there are different functional groups that each can reduce. Catalytic hydrogenation is the preferred method for reducing alkenes and alkynes
