A technique for separation of ions by rate and direction of migration in an electric field.
- 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...
The combination of critical temperature and critical pressure of a substance.
Spectrum associated with emission of electromagnetic radiation by atoms (or other species) resulting from electronic transitions from higher to lower energy states.
The geometric arrangement of orbitals containing the shared and unshared electron pairs surrounding the central atom of a molecule or polyatomic ion.
Percent by Mass
100% times the actual yield divided by theoretical yield.
A state of dynamic balance in which the rates of forward and reverse reactions are equal, there is no net change in concentrations of reactants or products while a system is at equilibrium.
A colorless, crystalline compound, XeF4, prepared by heating a gaseous mixture of fluorine and xenon.
An isotope of hydrogen whose atoms are twice as massive as ordinary hydrogen,deuterion atoms contain both a proton and a neutron in the nucleus.
A substance that speeds up a chemical reaction without being consumed itself in the reaction.
A substance that alters (usually increases) the rate at which a reaction occurs.
Different substances that have the same formula.
Conduction of electrical current by ions through a solution or pure liquid.
Derivatives of ammonia in which one or more hydrogen atoms have been replaced by organic groups.
Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.
of or derived from saccharin or a saccharine substance.
Cathode Ray Tube
Closed glass tube containing a gas under low pressure, with electrodes near the ends and a luminescent screen at the end near the positive electrode, produces cathode rays when high voltage is applied.
Conjugated Double Bonds
Double bonds that are separated from each other by one single bond -C=C-C=C-.
Aufbau ('building up') Principle
Describes the order in which electrons fill orbitals in atoms.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Coefficient of expansion
The ratio of the change in length or volumen of a body to the original lengthor volume for a unit change in temperature.
Chain Termination Step
The combination of two radicals, which removes the reactive species that propagate the change reaction.
It is the force in dynes acting along the surface of the liquid 1cm in length and perpendicular to it.
