- 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...
- 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...

In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...

Control Rods
Rods of materials such as cadmium or boron steel that act as neutron obsorbers (not merely moderaters) used in nuclear reactors to control neutron fluxes and therfore rates of fission.
Polarization
The buildup of a product of oxidation or a reduction of an electrode, preventing further reaction.
Silicones
Polymeric organosilicon compounds, contain individual or cross-linked Si-O chains or rings in which some oxygens of SiO4 tetrahedra are replaced by other groups.
xylidine
Any of six isomeric compounds that have the formula C8H11N, are derivatives of xylene, and resemble aniline: used in dye manufacture.
Optical Isomers
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.

An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.
Hydrolysis Constant
An equilibrium constant for a hydrolysis reaction.

Fractional Distillation
The process in which a fractioning column is used in distillation apparatus to separate components of a liquid mixture that have different boiling points.
