- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
- 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...
Solution in which no more solute will dissolve.
A term used to describe molecules and polyatomic ions that have one atom in the center and six atoms at the corners of a octahedron.
The amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase.
Chemical bonding resulting from the transfer of one or more electrons from one atom or a group of atoms to another.
Ability of a substance to exhibit amphiprotism by accepting donated protons.
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
A form of energy that flows between two samples of matter because of their differences in temperature.
In describing crystals, the number of nearest neighbours of an atom or ion. The number of donor atoms coordinated to a metal.
Compound in which a carbonyl group is bound to two alkyl or two aryl groups, or to one alkyl and one aryl group.
A reaction in which an atom or a group of atoms is replaced by another atom or group of atoms.
An atom or a group of atoms that carries an electric charge.
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.
Density is the ratio b/w Mass and Volume: D=M/V
The pressure exerted by one gas in a mixture of gases.
Any species that can accept a share in an electron pair.
The sum of the molalities of all solute particles in a solution.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
Unit of electrical charge.
