A spherically symmetrical atomic orbital, one per energy level.
- 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?
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- 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...
Unit of electrical charge.
A U-shaped tube containing electrolyte, which connects two half-cells of a voltaic cell.
A favourable interaction of two electrons with opposite m , values in the same orbital.
A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.
Anything that has mass and occupies space.
Process that occurs in electrolytic cells.
Compound containing the O-C-N group.Compound that can be considered a derivative of ammonia in which one or more hydrogens are replaced by a alkyl or aryl groups.
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
The smallest repeating unit of a substance. The molecule for nonionic substances
A salt containing an ionizable hydrogen atom. Acidic salt does not necessarily produce acidic solutions.
Solid consisting of two co-crystallized salts.
Emission of an electron from the surface of a metal caused by impinging electromagnetic radiation of certain minimum energy, current increases with increasing intensity of radiation.
Equilibria involving only one species in a single phase. For example, all gases, all liquids or all solids.
The drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive forces, or the depression of the surface of the liquid when cohesive forces exceed the adhesive forces.
Isomers that differ only in the way that atoms are oriented in space, consist of geometrical and optical isomers.
A device used to measure optical activity.
An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
Outermost electrons of atoms, usually those involved in bonding.
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
A device used for accelerating charged particles along a straight line path.
