Hydrocarbons that contain double or triple carbon-carbon bonds.
- 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...
- 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?
- 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...
- 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...
Reactions in which oxidation and reduction occur, also called redox reactions.
Refers to crystals having the same atomic arrangement.
A property that depends upon the amount of material in a sample.
A packet of light or electromagnetic radiation, also called quantum of light.
Method by which elemental sulfur is mined or extracted. Sulfur is melted with superheated water (at 170°C under high pressure) and forced to the surface of the earth as a slurry.
A protein that acts as a catalyst in biological systems.
Corrects standard electrode potentials for nonstandard conditions.
A measure of the relative tendency of an atom to attract electrons to itself when chemically combined with another atom.
A sample of matter composed of two or more substances, each of which retains its identity and properties.
An equilibrium in which processes occur continuously, with no net change. When two (or more) processes occur at the same rate so that no net change occurs.
Maximum amount of a specified product that could be obtained from specified amounts of reactants, assuming complete consumption of limiting reactant according to only one reaction and complete recovery of product.
A state of dynamic balance in which the rates of forward and reverse reactions are equal, there is no net change in concentrations of reactants or products while a system is at equilibrium.
Isomers involving exchanges of ligands between complex cation and complex anion of the same compound.
Negative logarithm of the concentration (mol/L) of the H3O+[H+] ion, scale is commonly used over a range 0 to 14.
A solution that contains a higher than saturation concentration of solute, slight disturbance or seeding causes crystallization of excess solute.
A neutron ejected at high kinetic energy in a nuclear reaction.
Refers to an optically active substance that rotates the plane of plane polarized light counterclockwise, also called levo.
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
Hess' Law of Heat Summation
The enthalpy change for a reaction is the same whether it occurs in one step or a series of steps.
Decomposition by heating a substance in the presence of a catalyst and in the absence of air.
