    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

  • 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...

  • 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...

  • 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.



Most Popular

Alums

Hydrated sulfates of the general formula M+M3+(SO4)2.12H2).

Single Bond

Covalent bond resulting from the sharing of two electrons (one pair) between two atoms.

Nucleons

Particles comprising the nucleus, protons and neutrons.

Cis-

The prefix used to indicate that groups are located on the same side of a bon about which rotation is restricted.

Ternary Compound

A compound consisting of three elements, may be ionic or covalent.

Ionization

In aqueous solution, the process in which a molecular compound reacts with water and forms ions.

High Spin Complex

Crystal field designation for an outer orbital complex, all t2g and eg orbitals are singly occupied before any pairing occurs.

Chain Reaction

A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.

 

Aufbau ('building up') Principle

Describes the order in which electrons fill orbitals in atoms.

Atom

The smallest particle of an element.
