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...

Interesting facts about metals
Metals have been used by people since ancient times. All the time the process of obtaining them was improved, useful alloys of various metals appeared. Let’s look at interesting facts about metals.

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...

Why do copper products change color, and what is the name of the process?
Probably, every person wants to know, why over time the copper turns green and becomes bloomed. This is easy to explain: that film is called patina.

Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
Most Popular
Corrosion
Oxidation of metals in the presence of air and moisture.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Radical
An atom or group of atoms that contains one or more unpaired electrons (usually very reactive species)
Polar Bond
Covalent bond in which there is an unsymmetrical distribution of electron density.
Flammable
A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
Fat
Solid triester of glycerol and (mostly) saturated fatty acids.
Allotropes
Different forms of the same element in the same physical state.
Electrode Potentials
Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.
Indicators
For acid-base titrations, organic compounds that exhibit different colors in solutions of different acidities, used to determine the point at which reaction between two solutes is complete.
Activity Series
A listing of metals (and hydrogen) in order of decreasing activity.
