The number of repeating corresponding points on a wave that pass a given observation point per unit time.
- 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...
- 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?
- 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...
- 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...
Colorless to slightly yellow fuming liquid.
Mol. Wt.: 153.39
Density: 1.685 @ 15.5C
Vapor Pressure: 40 mm @ 27.3C
Vapor Density: 5.3
Used as the phosphorus source for phosphorus diffusion.
Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
The zero point on the absolute temperature scale, -273.15°C or 0 K, theoretically, the temperature at which molecular motion ceases. The concept of an absolute zero temperature was first deduced from experiments with gases. When a fixed volume of gas is cooled, its pressure decreases with its temperature. Absolute zero physically possesses quantum mechanical zero-point energy.
A white, needlelike, crystalline, water-soluble solid or syrup, C6H10O8, usually made by the oxidation of cane sugar, glucose, or starch by nitric acid. Also called "Glucaric acid."
Allotropic Modifications (Allotropes)
Different forms of the same element in the same physical state.
A helium nucleus.
The amount of energy necessary to break one mole of bonds of a given kind (in gas phase).The amount of energy necessary to break one mole of bonds in a substance, dissociating the sustance in the gaseous state into atoms of its elements in the gaseous state.
Law of Combining Volumes (Gay-Lussac's Law)
At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.
A Lewis base in a coordination compound.
The direct solidification of a vapor by cooling, the reverse of sublimation.
Also called "phenosafranine". A purplish-red, water-soluble dye, C18H14N4, used for textiles and as a stain in microscopy.
A process for the catalyzed industrial production of ammonia from N2 and H2 at high temperature and pressure.
Bonding within metals due to the electrical attraction of positively charges metal ions for mobile electrons that belong to the crystal as a whole.
Trapping of heat at the surface of the earth by carbon dioxide and water vapour in the atmosphere.
Pauli Exclusion Principle
No two electrons in the same atom may have identical sets of four quantum numbers.
The hydrostatic pressure produced on the surface of a semipermable membrane by osmosis.
The arrangement of atoms (not lone pairs of electrons) around a central atom of a molecule or polyatomic ion.
A listing of metals (and hydrogen) in order of decreasing activity.
The number of moles of a component of a mixture divided by the total number of moles in the mixture.
The point at which chemically equivalent amounts of reactants have reacted.
