  • The most expensive metal in the world

    Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

  • Features of the Scanning Tunneling Microscope

    The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...

A measure of the intensity of heat, i.e. the hotness or coldness of a sample. or object.

Creating Malachite egg

One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but effective and visual, and as a result we will get something beautiful.

How is colored crystal made?

However, not everyone knows that in addition to the traditional transparent, there is still an unusually beautiful and spectacular colored crystal, which is obtained through the addition of various metal oxides into the glass. They give the crystal unusually noble shades of red, purple, blue, green and pink colors.

Use of diamonds

Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most brilliant and timeless gem.

Photochemical Oxidants

Photochemically produced oxidizing agents capable of causing damage to plants and animals.

Polyprotic Acid

An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.

Zone Refining

A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.
