  • 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...

  • 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'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...

Atomic Mass Unit (amu)

One twelfth of a mass of an atom of the carbon-12 isotope, a unit used for stating atomic and formula weights, also called dalton.

Solubility Product Constant

Equilibrium constant that applies to the dissolution of a slightly soluble compound.

Flash Point

The temperature at which a liquid will yield enough flamable vapour to ignite. There are various recognized industrial testing methods, therefore the method used must be stated.

Dipole

Refers to the separation of charge between two covalently bonded atoms.

Formal Charge

A method of counting electrons in a covalently bonded molecule or ion, counts bonding electrons as though they were equally shared between the two atoms.

Mole Fraction

The number of moles of a component of a mixture divided by the total number of moles in the mixture.

 

Hydrocarbons

Compounds that contain only carbon and hydrogen.

Buffer Solution

Solution that resists change in pH, contains either a weak acid and a soluble ionic salt of the acid or a weak base and a soluble ionic salt of the base.

Covalent Compounds

Compounds containing predominantly covalent bonds.

Solution

Homogeneous mixture of two or more substances.

Homonuclear

Consisting of only one element.

Safranine

Also called "phenosafranine". A purplish-red, water-soluble dye, C18H14N4, used for textiles and as a stain in microscopy.

DP number

The degree of polymerization, the average number of monomer units per polymer unit.

Coordination Isomers

Isomers involving exchanges of ligands between complex cation and complex anion of the same compound.

Energy

The capacity to do work or transfer heat.

xylidine

Any of six isomeric compounds that have the formula C8H11N, are derivatives of xylene, and resemble aniline: used in dye manufacture.

Chemical Change

A change in which one or more new substances are formed.

Molecular Formula

Formula that indicates the actual number of atoms present in a molecule of a molecular substance.

Critical Temperature

The temperature above which a gas cannot be liquefied, the temperature above which a substance cannot exhibit distinct gas and liquid phases.

Homogeneous Catalyst

A catalyst that exists in the same phase (solid, liquid or gas) as the reactants. The process is called Homogeneous Catalysis.
