Solution in which no more solute will dissolve.
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
- 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?
- 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...
Refers to species that have only six electrons in the highest energy level of the central element (many Lewis acids).
A substance that conducts electricity poorly in a dilute aqueous solution.
Potential difference, Ecell, between oxidation and reduction half-cells under nonstandard conditions.
Plating a metal onto a (cathodic) surface by electrolysis.
Heat of Vaporization
The amount of heat required to vaporize one gram of a liquid at its boiling point with no change in temperature. Usually expressed in J/g. The molar heat of vaporization is the amount of heat required to vaporize one mole of liquid at its boiling point with no change in temperature and usually expressed ion kJ/mol.
Adhesion of a species onto the surfaces of particles.
Compound produced by dehydration of a carbonic acid. General formula is R--C--O--C--R. Chemical compound that reacts with water to form an acid and are usually oxides of nonmetallic elements.
Valence Bond Theory
Assumes that covalent bonds are formed when atomic orbitals on different atoms overlap and the electrons are shared.
Hydrogen-Oxygen Fuel Cell
Fuel cell in which hydrogen is the fuel (reducing agent) and oxygen is the oxidizing agent.
The metal ion and its coordinating ligands but not any uncoordinated counter-ions.
A heterogeneous mixture in which solute-like particles do not settle out.
The interaction of orbitals on different atoms in the same region of space.
The dispersed (dissolved) phase of a solution.
Energy that is propagated by means of electric and magnetic fields that oscillate in directions perpendicular to the direction of travel of the energy.
Particles comprising the nucleus, protons and neutrons.
Alkaline Earth Metals
Group IIA metals
The oxide of a metal that reacts with water to form a base.
An orgainic ion carrying a positive charge on a carbon atom.
A neutral subatomic particle having a mass of 1.0087 amu.
The amount of energy absorbed in the process in which an electron is added to a neutral isolated gaseous atom to form a gaseous ion with a 1- charge, has a negative value if energy is released.
