- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- 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...
- 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...

Radioactive Tracer
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
Semipermable Membrane
A thin partition between two solutions through which certain molecules can pass but others cannot.
Solvation
The process by which solvent molecules surround and interact with solute ions or molecules.
Integrated Rate Equation
An equation giving the concentration of a reactant remaining after a specified time, has different mathematical form for different orders of reactants.
Metallurgy
Refers to the overall processes by which metals are extracted from ores.
Plasma
A physical state of matter which exists at extremely high temperatures in which all molecules are dissociated and most atoms are ionized.
Titration
A Procedure in which one solution is added to another solution until the chemical reaction between the two solutes is complete, the concentration of one solution is known and that of the other is unknown.
Gem-dimethyl group
Two methyl groups of the same carbon atom.
Equilibrium Constant
A quantity that characterizes the position of equilibrium for a reversible reaction, its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
Conformations
Structures of a compound that differ by the extent of rotation about a single bond.
