Conduction of electrical current through a metal or along a metallic surface.
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...
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...
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.
What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
The undesirable overgrowth of vegetation caused by high concentrates of plant nutrients in bodies of water.
The reaction in which hydrogen adds across a double or triple bond.
Ligand that exerts a strong crystal or ligand electrical field and generally forms low spin complexes with metal ions when possible.
The process by which solvent molecules surround and interact with solute ions or molecules.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
Discovered : known to ancient civilisations
Origin : The name is derived from 'Cuprum', the Latin name for Cyprus.
A Nuclear particle with the mass of an electron but opposite charge.
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
Any kind of matter all specimens of which have the same chemical composition and physical properties.
Density is the ratio b/w Mass and Volume: D=M/V
