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 separation of a liquid mixture into its components on the basis of differences in boiling points. The process in which components of a mixture are separated by boiling away the more volitile liquid.
Nuclear Binding Energy
Energy equivalent of the mass deficiency, energy released in the formation of an atom from the subatomic particles.
Handmade crystal glass as a work of art
In order for the colored crystal to open in all its beauty and sparkle with every face natural light is required. Handmade crystal glass has specific tactile and aesthetic properties - it is pleasant to touch, it seems to radiate heat. To appreciate the quality and beauty of such things, of course, it is not enough to look at the picture.
Optical Isomers
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
Hydrocarbons
Compounds that contain only carbon and hydrogen.
Differential Thermometer
A thermometer used for accurate measurement of very small changes in temperature.

Crystal Lattice
A pattern of arrangement of particles in a crystal.
Artificial Transmutation
An artificially induced nuclear reaction caused by the bombardment of a nucleus with subatomic particiles or small nucei.
Equation of State
An equation that describes the behavior of matter in a given state, the van der Waals equation describes the behavior of the gaseous state.
