Crystal field designation for an outer orbital complex, all t2g and eg orbitals are singly occupied before any pairing occurs.
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- 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 catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
Energy that is propagated by means of electric and magnetic fields that oscillate in directions perpendicular to the direction of travel of the energy.
A salt containing an ionizable OH group.
A plant extract that has a distinctive odour or flavour.
Strong Field Ligand
Ligand that exerts a strong crystal or ligand electrical field and generally forms low spin complexes with metal ions when possible.
Density is the ratio b/w Mass and Volume: D=M/V
The solute-like species in a colloid.
Amount of solute per unit volume or mass of solvent or of solution.
A substance such as hydrogen, deuterium, oxygen or paraffin capable of slowing fast nuetrons upon collision.
Outermost electrons of atoms, usually those involved in bonding.
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
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.
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
The mass percent of each element in a compound.
A proton acceptor
An organic ion carrying a negative charge on a carbon atom.
The degree of polymerization, the average number of monomer units per polymer unit.
Substances consumed in a chemical reaction.
An orbit resulting from overlap and mixing of atomic orbitals on different atoms. An MO belongs to the molecule as a whole.
Poor electric and heat conductor.
