Secondary voltaic cell used in most automobiles.
- 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...
- 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?
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
A noncrystalline solid with no well-defined ordered structure.
Homogeneous mixture of two or more substances.
The hydrostatic pressure produced on the surface of a semipermable membrane by osmosis.
The prefix used to indicate that groups are located on the same side of a bon about which rotation is restricted.
Absorption of high energy radiation by a substance and subsequent emission of visible light.
A large molecule consisting of chains or rings of linked monomer units, usually characterized by high melting and boiling points.
The relative order of tendencies for elements and their simple ions to act as oxidizing or reducing agents, also called the activity series.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
A spherically symmetrical atomic orbital, one per energy level.
Ytterbia is a colorless compound, Yb2O3, used in certain alloys and ceramics. Also known as ytterbium oxide.
Adhesion of a species onto the surfaces of particles.
Very weak and very short-range attractive forces between short-lived temporary (induced) dipoles, also called dispersion Forces.
The heat content of a specific amount of substance, defined as E= PV.
Resistance offered by the molecules of a liquid to flow is termed as viscosity.
Outer Orbital Complex
Valence bond designation for a complex in which the metal ion utilizes d orbitals in the outermost (occupied) shell in hybridization.
A compound that contains more than one double bond per molecule.
A soap-like emulsifer that contains a sulfate, SO3 or a phosphate group instead of a carboxylate group.
Regular periodic variations of properties of elements with atomic number (and position in the periodic table).
Law of Definite Proportions (Law of Constant Composition)
The law stating that a pure substance will always have the same percent by weight. Different samples of a pure compound always contain the same elements in the same proportions by mass.
The degree of polymerization, the average number of monomer units per polymer unit.
