The total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases.
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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?
A Compound of the general formula R-C-O-R1 where R and R1 may be the same or different, and may be either aliphatic or aromatic.
Adhesion of a species onto the surfaces of particles.
Nickel-cadmium cell (Nicad battery)
A dry cell in which the anode is Cd, the cathode is NiO2, and the electrolyte is basic.
A common type of dry cell.
Chemical Hygiene Officer (CHO)
A person or employee who is qualified by training or experience to provide technical guidance in the development and implementations of the provisions of a Chemical Hygiene Plan (CHP)
High energy electromagnetic radiation. A highly penetrating type of nuclear radiation similar to x-ray radiation, except that it comes from within the nucleus of an atom and has a higher energy. Energywise, very similar to cosmic ray except that cosmic rays originate from outer space.
A spherically symmetrical atomic orbital, one per energy level.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
Chemical bonding resulting from the transfer of one or more electrons from one atom or a group of atoms to another.
The solid and liquid states.
A brownish smog occurring in urban areas receiving large amounts of sunlight, caused by photochemical (light-induced) reactions among nitrogen oxides, hydrocarbons and other components of polluted air that produce photochemical oxidants.
Equation for a chemical reaction in which all formulas are written as if all substances existed as molecules, only complete formulas are used.
Particles comprising the nucleus, protons and neutrons.
Elements 89 to 103 (between lawrencium and actinium) on the periodic table. Only the first four have been found in nature in appreciable amounts. The remainder have been produced synthetically.
The degree of polymerization, the average number of monomer units per polymer unit.
One faraday of electricity corresponds to the charge on 6.022 x 1023 electrons, or 96,487.301 coulombs.
Number of moles of solute per litre of solution.
A hypothetical gas that obeys exactly all postulates of the kinetic-molecular theory.
A noncrystalline solid with no well-defined ordered structure.
A Nuclear particle with the mass of an electron but opposite charge.
