Elements 58 to 71 (after lanthanum).
- 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...
- 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...
- 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...
Specific Rate Constant
An experimentally determined (proportionality) constant, which is different for different reactions and which changes only with temperature, k in the rate-law expression: Rate = k [A] x [B]v.
Process that occurs in electrolytic cells.
Reactions in which two compounds react to form two new compounds, with no changes in oxidation number. Reactions in which the ions of two compounds exchange partners.
Adhesion of a species onto the surfaces of particles.
Placing a thin layer of zinc on a ferrous material to protect the underlying surface from corrosion.
Solubility Product Principle
The solubility product constant expression for a slightly soluble compound is the product of the concentrations of the constituent ions, each raised to the power that corresponds to the number of ions in one formula unit.
Two or more forms of atoms of the same element with different masses, atoms containing the same number of protons but different numbers of neutrons.
Second Law of Thermodynamics
The universe tends toward a state of greater diorder in spontaneous processes.
A partially filled band or a band of vacant energy levels just higher in energy than a filled band, a band within which, or into which, electrons must be promoted to allow electrical conduction to occur in a solid.
A small, calibrated electroscope worn by laboratory personnel and designated to detect and measure incident ionizing radiation or chemical exposure.
A reaction in which two atoms or groups of atoms are added to a molecule, one on each side of a double or triple bond. Types of addition reaction include electrophilic, nucleophilic (polar) and free radical addition (non-polar).
Low Spin Complex
Crystal field designation for an inner orbital complex, contains electrons paired t2g orbitals before eg orbitals are occupied in octahedral complexes.
The relative amounts of reactants and products involved in a reaction, maybe the ratio of moles. millimoles, or masses.
A highly reactive chemical species carrying no charge and having a single unpaired electron in an orbital.
Ions resulting from the formation of coordinate covalent bonds between simple ions and other ions or molecules.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
The smallest particle of an element.
Short-lived species formed by the collision of dissolved ions of opposite charges.
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
The pressure of the gas above a solution is proportional to the concentration of the gas in the solution.
