  • 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...

  • Protein Design: Automated protein discovery and synthesis

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

  • 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...

  • Diamonds Are Forever

    Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?

Accuracy

How closely a measured value agrees with the correct value.

Anion

A negative ion, an atom or goup of atoms that has gained one or more electrons.

 

Crystalline Solid

A solid characterized by a regular, ordered arrangement of particles.

Conduction Band

A partially filled band or a band of vacant energy levels just higher in energy than a filled band, a band within which, or into which, electrons must be promoted to allow electrical conduction to occur in a solid.

Ferromagnetism

The ability of a substance to become permanently magnetized by exposure to an external magnetic field.

Isoelectric

Having the same electronic configurations.
