- 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?
- Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...
- Use of diamonds
Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

Precipitate
An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
Standard Reaction
A reaction in which the numbers of moles of reactants shown in the balanced equation, all in their standard states, are completely converted to the numbers of moles of products shown in the balanced equation, also sall at their standard state.
Band
A series of very closely spaced, nearly continuous molecular orbitals that belong to the crystal as a whole.

Chemical Equation
Description of a chemical reaction by placing the formulas of the reactants on the left and the formulas of products on the right of an arrow.
Lone Pair
Pair of electrons residing on one atom and not shared by other atoms, unshared pair.
Heteronuclear
Consisting of different elements.
Basic Salt
A salt containing an ionizable OH group.
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.
Law of Definite Proportions (Law of Constant Composition)
The law stating that a pure substance will always have the same percent by weight. Different samples of a pure compound always contain the same elements in the same proportions by mass.
