Forces of attraction between a liquid and another surface.
- 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...
- 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...
- 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...
Law of Conservation of Matter
There is no detectable change in the quantity of matter during an ordinary chemical reaction.
Industrial process by which sulfur trioxide and sulfuric acid are produced from sulfur dioxide.
Chemical bond formed by the sharing of one or more electron pairs between two atoms.
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
The time required for half of a reactant to be converted into product(s). The time required for half of a given sample to undergo radioactive decay.
Electron Deficient Compounds
Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
The slowest step in a mechanism, the step that determines the overall rate of reaction.
Bonding of atoms of the same element into chains or rings.
The bonding together of atoms of the same element to form chains.
The ability of an element to bond to itself.
The concept in which two or more equivalent dot formulas for the same arrangement of atoms (resonance structures) are necessary to describe the bonding in a molecule or ion.
The amount of energy necessary to break one mole of bonds of a given kind (in gas phase).The amount of energy necessary to break one mole of bonds in a substance, dissociating the sustance in the gaseous state into atoms of its elements in the gaseous state.
An element below and to the left of the stepwise division (metalloids) in the upper right corner of the periodic table, about 80% of the known elements are metals.
The variations in properties of elements with their position in the periodic table.
The rotation of plane polarized light by one of a pair of optical isomers.
A process pertaining to a change in structure of a protein form regular to irregular arrangement of the polypeptide chains.
A device for accelerating charged particles along a spiral path.
Colloidal suspension of a solid dispersed in a liquid, a semirigid solid.
Any of six colorless, crystalline, isomeric acids having the formula C9H10O2, derived from xylene.
The amount of heat required to raise the temperature of one gram of water from 14.5°C to 15.5°C. 1 calorie = 4.184 joules.
Forces between individual particles (atoms, molecules, ions) of a substance.
