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...

Ozone
We breathe 24 hours a day, 7 days a week, consuming about 25 kg of air every day. It turns out that we practically predetermine our health by the air we breathe.

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...

The most expensive metal in the world
Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

Nucleons
Particles comprising the nucleus, protons and neutrons.
Nuclide Symbol
Symbol for an atom A/Z E, in which E is the symbol of an element, Z is its atomic number, and A is its mass number.
Nuclear Reaction
Involves a change in the composition of a nucleus and can evolve or absorb an extraordinarily large amount of energy.
Molecular Orbital Theory
A theory of chemical bonding based upon the postulated existence of molecular orbitals.
Solubility Product Constant
Equilibrium constant that applies to the dissolution of a slightly soluble compound.
Ostwald Process
A process for the industrial production of nitrogen oxide and nitric acid from ammonia and oxygen.
Crystal Field Theory
Theory of bonding in transition metal complexes in which ligands and metal ions are treated as point charges, a purely ionic model, ligand point charges represent the crystal (electrical) field perturbing the metal?s d orbitals containing nonbonding electrons.
Transition State Theory
Theory of reaction rates that states that reactants pass through high-energy transition states before forming products.
Standard Entropy
The absolute entropy of a substance in its standard state at 298 K.
Emission Spectrum
Spectrum associated with emission of electromagnetic radiation by atoms (or other species) resulting from electronic transitions from higher to lower energy states.
