- 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.
- 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...

Delocalization
Of electrons, refers to bonding electrons that are distributed among more than two atoms that are bonded together, occurs in species that exhibit resonance.
The formation of a set of molecular orbitals that extend over more than two atoms, important in species that valence bond theory describes in terms of resonance.
Hydrolysis Constant
An equilibrium constant for a hydrolysis reaction.
Neutralization
The reaction of an acid with a base to form a salt and water. Usually, the reaction of hydrogen ions with hydrogen ions to form water molecules.
Bronsted-Lowry Base

Cis-Trans Isomerism
A type of geometrical isomerism related to the angles between like ligands.
Standard Molar Volume
The volume occupied by one mole of an ideal gas under standard conditions, 22.4liters.
Flammable
A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
Ionic Geometry
The arrangement of atoms (not lone pairs of electrons) about the central atom of a polyatomic ion.
Homologous Series
A series of compounds in which each member differs from the next by a specific number and kind of atoms.
Absolute Entropy (of a substance)
The increase in the entropy of a substance as it goes from a perfectly ordered crystalline form at 0 °K (where its entropy is zero) to the temperature in question.
Entropy is a measure of the “dilution” of thermal energy.
