An orgainic ion carrying a positive charge on a carbon atom.
- 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...
- 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...
- 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?
Pair of electrons residing on one atom and not shared by other atoms, unshared pair.
Electron emitted from the nucleus when a neuton decays to a proton and an electron.
Amount of a specified pure product actually obtained from a given reaction. Compare with Theoretical Yield.
A system in which controlled nuclear fisson reactions generate heat energy on a large scale, which is subsequently converted into electrical energy.
Third Law of Thermodynamics
The entropy of a hypothetical pure, perfect, crystalline sustance at absolute zero temperature is zero.
An aliphatic acid, many can obtained from animal fats.
The rotation of plane polarized light by one of a pair of optical isomers.
Compartment in which the oxidation or reduction half-reaction occurs in a voltaic cell.
Differential Scanning Calorimetry (DSC)
A technique for measuring the temperature, direction, and magnitude of thermal transitions in a sample material by heating/cooling and comparing the amount of energy required to maintain its rate of temperature increase or decrease with an inert reference material under similar conditions.
Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
The number of moles of a component of a mixture divided by the total number of moles in the mixture.
A highly reactive chemical species carrying no charge and having a single unpaired electron in an orbital.
The degree of polymerization, the average number of monomer units per polymer unit.
A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.
An arrangement of elements in order of increasing atomic numbers that also emphasizes periodicity.
The interaction of orbitals on different atoms in the same region of space.
The rate at which a particular substance will vapourize (evaporate) when compared to the rate of a known substance such as ethyl ether. This term is especially useful for health and fire-hazard considerations.
Molecular orbital resulting from head-on overlap of two atomic orbitals.
Heat of Crystallization
The amount of heat that must be removed from one gram of a liquid at its freezing point to freeze it with no change in temperature.
The geometric arrangement of orbitals containing the shared and unshared electron pairs surrounding the central atom of a molecule or polyatomic ion.
