A device for observing the paths of speeding particiles as vapor molecules condense on them to form foglike tracks.
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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 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...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- 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...
A group of atoms derived from an alkane by the removal of one hydrogen atom.
Any of a number of lines corresponding to definite wavelengths of an atomic emission or absorption spectrum, represents the energy difference between two energy levels.
Aufbau ('building up') Principle
Describes the order in which electrons fill orbitals in atoms.
Compounds that contain more than two elements but are named like binary compounds.
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
Corrects standard electrode potentials for nonstandard conditions.
An element below and to the left of the stepwise division (metalloids) in the upper right corner of the periodic table, about 80% of the known elements are metals.
The complex series of reactions by which nitrogen is slowly but continually recycled in the atmosphere, lithosphere and hydrosphere.
Strong Field Ligand
Ligand that exerts a strong crystal or ligand electrical field and generally forms low spin complexes with metal ions when possible.
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
Solution that resists change in pH, contains either a weak acid and a soluble ionic salt of the acid or a weak base and a soluble ionic salt of the base.
One of the two mirror-image forms of an optically active molecule.
Half-cells in which the oxidized and reduced forms of a species are present at unit activity, 1.0M solutions of dissolved ions, 1.0atm partial pressure of gases, and pure solids and liquids.
A substance that cannot be decomposed into simpler substances by chemical means.
A salt or ester of xanthic acid. Many xanthates have a yellow color. Xanthates are used as flotation agents in mineral processing.
The amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase.
A mixture that does not have uniform composition and properties throughout.
A common type of dry cell.
Unit of electrical current, one ampere equals one coulomb per second.
An atomic emission or absorption spectrum.
