Ordinary batteries (voltaic cells) for flashlights. radios, and so on, many are Leclanche cells.
- 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...
- 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...
- 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?
Colloidal suspension of a liquid in a liquid.
Weighted average of the masses of the constituent isotopes of an element, The relative masses of atoms of different elements.
An ionization reaction between identical molecules.
Refers to an optically active substance that rotates the plane of plane polarized light counterclockwise, also called levo.
The quantity of product formed by the interaction of two or more substances, generally expressed as a percentage of the quantity obtained to that theoretically obtainable.
A U-shaped tube containing electrolyte, which connects two half-cells of a voltaic cell.
Refers to the separation of charge between two covalently bonded atoms.

One equivalent weight of a substance is produced at each electrode during the passage of 96,487 coulombs of charge through an electrolytic cell.
The arrangement of atoms (not lone pairs of electrons) about the central atom of a polyatomic ion.
A catalyst that exists in the same phase (solid, liquid or gas) as the reactants. The process is called Homogeneous Catalysis.
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.
Oxidation of metals in the presence of air and moisture.
The direct vaporization of a sold by heating without passing through the liquid state.
