A compound that contains more than one double bond per molecule.
- 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...
- 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?
- 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...
- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
Lead Storage Battery
Secondary voltaic cell used in most automobiles.
High energy electromagnetic radiation. A highly penetrating type of nuclear radiation similar to x-ray radiation, except that it comes from within the nucleus of an atom and has a higher energy. Energywise, very similar to cosmic ray except that cosmic rays originate from outer space.
An impure form of carbon obtained by destructive distillation of coal or petroleum.
The combination of critical temperature and critical pressure of a substance.
A property that depends upon the amount of material in a sample.
The ability to react with both acids and bases.Ability of substance to act as either an acid or a base.
The point at which an indicator changes colour and a titration is stopped.
Radius of an atom.
A heavy, colorless, chemically inactive, monatomic gaseous element used for filling radio, television, and luminescent tubes. Symbol: Xe, at. wt.: 131.30, at. no.: 54.
The rotation of plane polarized light by one of a pair of optical isomers.
Refers to the separation of charge between two covalently bonded atoms.
Colloidal particles that repel water molecules.
Chemical bond formed by the sharing of one or more electron pairs between two atoms.
Mixing a set of atomic orbitals to form a new set of atomic orbitals with the same total electron capacity and with properties and energies intermediate between those of the original unhybridized orbitals.
A neutron ejected at high kinetic energy in a nuclear reaction.
Energy that matter possesses by virtue of its position, condition or composition.
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
A ternary compound containing H, O, and another element, often a nonmetal.
Weak Field Ligand
A Ligand that exerts a weak crystal or ligand field and ge- nerally forms high spin complexes with metals.
A white, needlelike, crystalline, water-soluble solid or syrup, C6H10O8, usually made by the oxidation of cane sugar, glucose, or starch by nitric acid. Also called "Glucaric acid."
