Researchers Just Accidentally Discovered A Process That Turns CO2 Directly Into Ethanol

Researchers Just Accidentally Discovered A Process That Turns CO2 Directly Into Ethanol

In a new twist to waste-to-fuel technology, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. Their finding, which involves nanofabrication and catalysis science, was serendipitous.

Whitening the Taj Mahal

Whitening the Taj Mahal

Mark Twain once remarked the world is divided between two types of people: those who have seen the Taj Mahal and those who have not. The Taj is one of the most recognizable landmarks in the world and the image most associated with India.

India has experienced exponential industrial growth in recent years. Environmental pollution spurred by industry and automobiles has long been observed to be progressively destroying the Taj Mahal’s white marble surface. Pollution is yellowing the Taj Mahal – but scientists are treating it with something called Fuller’s Earth.

How to make the Pharaoh’s Serpent

How to make the Pharaoh’s Serpent

Many chemical reactions are quite shocking, but this one is definitely something else. Take a look at the decomposition of Mercury(II) thiocyanate (Hg(SCN)2) called Pharaoh’s Serpent Reaction.

Warning: This experiments requires the handling of dangerous and volatile chemicals. It must only be carried out in a fumehood or outdoors.

All chemicals must be disposed of properly. Everything will be contaminated with mercury/mercury salts. NOTHING CAN GO DOWN THE DRAIN OR IN THE GARBAGE. Only carry out this experiment if you can dispose of the chemicals and combustion products properly.

Every step of this synthesis deals with dangerous or toxic materials. Gloves, safety glasses and a lab coat are mandatory.

Here is a video to show you how volatile elemental mercury is. It lets off a lot of vapor and breathing this must be avoided.
