A commercial term used to describe ethanol that has been rendered unfit for human consumption because of the addition of harmful ingredients to make it sales tax-expempt.
- 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...
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
Sand, rock, and other impurities surrounding the mineral of interest in an ore.
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.
A two-armed barometer.
Radius of an atom.
Density is the ratio b/w Mass and Volume: D=M/V
Colloidal suspension of liquid in gas.
Refers to substances that crystallize in more than one crystalline arrangement.
Forces between individual particles (atoms, molecules, ions) of a substance.
The amount of heat required to raise the temperature of a body (of any mass) one degree Celsius.
Atomic Mass Unit (amu)
One twelfth of a mass of an atom of the carbon-12 isotope, a unit used for stating atomic and formula weights, also called dalton.
Liquid triester of glycerol and unsaturated fatty acids.

Colloidal suspension of a liquid in a liquid.
The basic unit used to describe the intensity of radioactivity in a sample of material. One curie equals 37 billion disintegrations per second or approximately the amount of radioactivty given off by 1 gram of radium.
Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.
