Rods of materials such as cadmium or boron steel that act as neutron obsorbers (not merely moderaters) used in nuclear reactors to control neutron fluxes and therfore rates of fission.
- 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.
- 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...
- 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...
Compound in which an alkyl or aryl group and a hydrogen atom are attached to a carbonyl group and a hydrogen atom are attached to a carbonyl group, general formula, O-R-C-H
The number of repeating corresponding points on a wave that pass a given observation point per unit time.
The solute-like species in a colloid.
Compound containing the O-C-N group.Compound that can be considered a derivative of ammonia in which one or more hydrogens are replaced by a alkyl or aryl groups.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
A gas filled tube which discharges electriaclly when ionizing radiation passes through it.
Any species that can make available a share in an electron pair.
Activity of a component of ideal mixture
A dimensionless quantity whose magnitude is: equal to molar concentration in an ideal solution, equal to partial pressure in an ideal gas mixture, and defined as 1 for pure solids or liquids.
Conjugated Double Bonds
Double bonds that are separated from each other by one single bond -C=C-C=C-.
Pauli Exclusion Principle
No two electrons in the same atom may have identical sets of four quantum numbers.
Ytterbia is a colorless compound, Yb2O3, used in certain alloys and ceramics. Also known as ytterbium oxide.
The temperature above which a gas cannot be liquefied, the temperature above which a substance cannot exhibit distinct gas and liquid phases.
The pressure of the gas above a solution is proportional to the concentration of the gas in the solution.
Process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.
Any of a group of dyes having a molecular structure related to that of xanthene in which the aromatic (C6H4) groups are the chromophore.
Covalent bond in which electron density is symmetrically distributed.
The buildup of a product of oxidation or a reduction of an electrode, preventing further reaction.
The time required for half of a reactant to be converted into product(s). The time required for half of a given sample to undergo radioactive decay.
Magnetic Quantum Number (mc)
Quantum mechanical solution to a wave equation that designates the particular orbital within a given set (s, p, d, f ) in which a electron resides.
Number of moles of a solute that dissolve to produce a litre of saturated solution.
