A unit of energy in the SI system. One joule is 1 kg. m2/s2 which is also 0.2390 calorie.
- 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...
A colorless, crystalline compound, XeF4, prepared by heating a gaseous mixture of fluorine and xenon.
Beginning in the third energy level, aset of five degenerate orbitals per energy level, higher in energy than s and p orbitals of the same energy level.
A proton acceptor
The elements in a horizontal row of the periodic table.
The shape assumed by the surface of a liquid in a cylindrical container.
Nuclear Binding Energy
Energy equivalent of the mass deficiency, energy released in the formation of an atom from the subatomic particles.
Forcing solvent molecules to flow through a semipermable membrane from a concentated solution into a dilute solution by the application of greater hydrostatic pressure on concentrated side than the osmotic pressure opposing it.
Ions in a solution that do not participate in a chemical reaction.
Physical properties of solutions that depend upon the number but not the kind of solute particles present.
A substance of two or more elements in fixed proportions. Compounds can be decomposed into their constituent elements.
Bonds resulting from the head-on overlap of atomic orbitals, in which the region of electron sharing is along and (cylindrically) symmetrical to the imaginary line connecting the bonded atoms.
An ionization reaction between identical molecules.
Method by which hydrophobic (water-repelling) particles of an ore are separated from hydrophilic (water-attracting) particles of a metallurgical pretreatment process.
Description of the quantitative relationships among substances as they participate in chemical reactions.
A thermodynamic state or property that measures the degree of disorder or randomness of a system.
Electrons in filled sets of s , p orbitals between the nucleus and outer shell electrons shield the outer shell electrons somewhat from the effect of protons in the nucleus, also called screening effect.
Colloidal particles that repel water molecules.
Very weak and very short-range attractive forces between short-lived temporary (induced) dipoles, also called dispersion Forces.
The spontaneous disintegration of atomic nuclei.
Molecular orbital resulting from head-on overlap of two atomic orbitals.
