The ability of a substance to be broken down into simpler substances by bacteria.
- 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?
- 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...
- 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...
Secondary Voltaic Cells
Voltaic cells that can be recharged, original reactanats can be regenerated be reversing the direction of the current flow.
A substance that does not conduct electricity at low temperatures but does so at higher temperatures.
Colloidal suspension of a solid dispersed in a liquid, a semirigid solid.
A thin partition between two solutions through which certain molecules can pass but others cannot.
A unit of pressure, the pressure that will support a column of mercury 760 mm high at 0 °C.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
Having the same electronic configurations.

All orbitals of a given sublevel must be occupied by single electrons before pairing begins.
Different forms of the same element in the same physical state.
Ideal Gas Law
The product of pressure and the volume of an ideal gas is directly proportional to the number of moles of the gas and the absolute temperature.
An aliphatic acid, many can obtained from animal fats.
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.
Regular periodic variations of properties of elements with atomic number (and position in the periodic table).
A chemical or compound that causes a sudden, almost instantaneous release or pressure, gas, heat and light when subjected to sudden shock, pressure, high temperature or applied potential.
