Nuclide that is produced in a nuclear decay.
- 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...
A device used to measure the densities of liquids and solutions.
A series of very closely spaced, nearly continuous molecular orbitals that belong to the crystal as a whole.
The ability to react with both acids and bases.Ability of substance to act as either an acid or a base.
An atom in a molecule or polyatomic ion that is bonded to more than one other atom.
The temperature above which a gas cannot be liquefied, the temperature above which a substance cannot exhibit distinct gas and liquid phases.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
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.
A substance capable of causing or producing cancer in mammals.
Isomers in which a particular ligand bonds to a metal ion through different donor atoms.
The range of concentrations over which a flammable vapour mixed with proper ratios of air will ignite or explode if a source of ignitions is provided.
Crystal Lattice Energy
Amount of energy that holds a crystal together, the energy change when a mole of solid is formed from its constituent molecules or ions (for ionic compounds) in their gaseous state.
Mathematical method of treating particles on the basis of quantum theory, which assumes that energy (of small particles) is not infinitely divisible.
Standard Electrode Potential
By convention, potential, Eo, of a half-reaction as a reduction relative to the standard hydrogen electrode when all species are present at unit activity.
Integral number of protons in the nucleus, defines the identity of element.
Absorption of high energy radiation by a substance and subsequent emission of visible light.
The point at which an indicator changes colour and a titration is stopped.
Equilibrium or Chemical Equilibrium
A state of dynamic balance in which the rates of forward and reverse reactions are equal, the state of a system when neither forward or reverse reaction is thermodynamically favored.
A substance of two or more elements in fixed proportions. Compounds can be decomposed into their constituent elements.
Substances consumed in a chemical reaction.
A salt containing an ionizable OH group.
