  • 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...

  • 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...

  • 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...

  • 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.

Hydrophilic Colloids

Colloidal particles that repel water molecules.

Homonuclear

Consisting of only one element.

Raoult's Law

The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.

S Orbital

A spherically symmetrical atomic orbital, one per energy level.

Polyprotic Acid

An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.

Coordination Number

In describing crystals, the number of nearest neighbours of an atom or ion. The number of donor atoms coordinated to a metal.

Thermal Cracking

Decomposition by heating a substance in the presence of a catalyst and in the absence of air.

 

Allotropes

Different forms of the same element in the same physical state.

Doublet

Two peaks or bands of about equal intensity appearing close together on a spectrogram.

Dispersed Phase

The solute-like species in a colloid.

Kinetic-molecular Theory

A theory, that attempts to explain macroscopic observations on gases in microscopic observations on gases in microscopic observations on gases in microscopic or molecular terms.

Dimer

Molecule formed by combination of two smaller (identical) molecules.

Nuclides

Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.

Electrolyte

A substance whose aqueous solutions conduct electricity.

 

Ioniztion

The breaking up of a compound into separate ions.

Sigma Orbital

Molecular orbital resulting from head-on overlap of two atomic orbitals.

Metallic Conduction

Conduction of electrical current through a metal or along a metallic surface.

Electrophoresis

A technique for separation of ions by rate and direction of migration in an electric field.

Nitric Acid

HNO3: A strong acid, it is toxic and can cause severe burns. Transparent colorless or yellowish, fuming, suffocating, caustic and corrosive liquid. Nitric acid boiling point is 83C. A 70 percent solution is used in the S.S.E. laboratory for junction depth measurements. Nitric acid is also present in the metal etch solution used for the Aluminum etch procedure.

Resonance

The concept in which two or more equivalent dot formulas for the same arrangement of atoms (resonance structures) are necessary to describe the bonding in a molecule or ion.
