- 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...
- Protein Design: Automated protein discovery and synthesis
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...
- Gas of rotten eggs
If you happen to break a rotten egg, then you know the smell of hydrogen sulfide, because the stench of the spoiled egg depends on of its presence in rotting protein substances.
- 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?

Nitric Acid
HNO3: A strong acid, it is toxic and can cause severe burns. Transparent colorless or yellowish, fuming, suffocating, caustic and corrosive liquid. Nitric acid boiling point is 83C. A 70 percent solution is used in the S.S.E. laboratory for junction depth measurements. Nitric acid is also present in the metal etch solution used for the Aluminum etch procedure.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Two chemistry egg tricks
The French have a saying: "You cannot cook an omelet without breaking eggs."Chemists hearing this proverb totally disagree. There is nothing easier than cleaning an egg without breaking its shell.
Probably our readers have already guessed how to do this, as it’s known that the hard shell of the egg is carbon dioxide, like chalk and marble.
Chemical Bonds
The attractive forces that hold atoms together in elements or compounds.
Paramagnetism
Attraction toward a magnetic field, stronger than diamagnetism, but still weak compared to ferromagnetism.
Cloud Chamber
A device for observing the paths of speeding particiles as vapor molecules condense on them to form foglike tracks.
Supersaturated Solution
A solution that contains a higher than saturation concentration of solute, slight disturbance or seeding causes crystallization of excess solute.
D-Orbitals
Beginning in the third energy level, aset of five degenerate orbitals per energy level, higher in energy than s and p orbitals of the same energy level.
Periodicity
Regular periodic variations of properties of elements with atomic number (and position in the periodic table).
Ionization Constant
Equilibrium constant for the ionization of a weak electrolyte.
