A process for the industrial production of nitrogen oxide and nitric acid from ammonia and oxygen.
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
The arrangement of atoms (not lone pairs of electrons) around a central atom of a molecule or polyatomic ion.
A heterogeneous mixture in which solute-like particles settle out of solvent-like phase some time after their introduction.
A property that depends upon the amount of material in a sample.
Chemical Hygiene Plan (CHP)
A written program developed and implemented by an employer designating proceedures, equipment, personal protective equipment, and work practices that are capable of protecting employees from the health hazards presented by hazardous chemicals usid in that particular workplace.
The temperature at which liquid and solid coexist in equilibrium, also the freezing point.
The ability of one liquid to mix with (dissolve in) another liquid.
Molecule formed by combination of two smaller (identical) molecules.
Forcing solvent molecules to flow through a semipermable membrane from a concentated solution into a dilute solution by the application of greater hydrostatic pressure on concentrated side than the osmotic pressure opposing it.
The process by which solvent molecules surround and interact with solute ions or molecules.
Hydrolysis of esters in the presence of strong soluable bases.
Discovered : known to ancient civilisations.
Origin : The name comes from the Anglo-Saxon ‘iren’, and the symbol from the Latin ‘ferrum’, meaning iron.
Description :Iron is an enigma - it rusts easily and yet is the most important of all metals, world production exceeds 700 million tons a year. Small amounts of carbon are added to iron to produce steel and when chromium.
is added to this, the result is non-corroding stainless steel (small amounts of nickel may also be added). Iron is also an essential element for all forms of life. The average human contains about 4 grams, much of which circulates as haemoglobin in the blood, the job of which is to carry oxygen from our lungs to where it is needed. If the diet does not contain 10 milligrams a day, anaemia will eventually develop. Foods such as liver, kidney, molasses, brewer’s yeast, cocoa and liquorice contain a lot of iron.

Conjugate Acid-base Pair
In Bronsted-Lowry terminology, a reactant and product that differ by a proton, H+.
The degree of polymerization, the average number of monomer units per polymer unit.
Allotropic Modifications (Allotropes)
Different forms of the same element in the same physical state.
Forces between individual particles (atoms, molecules, ions) of a substance.
Compound in which a carbonyl group is bound to two alkyl or two aryl groups, or to one alkyl and one aryl group.
A substance that conducts electricity poorly in a dilute aqueous solution.
Metal with low ionization energy that loses electrons readily to form cations.
Compartment in which the oxidation or reduction half-reaction occurs in a voltaic cell.
In aqueous solution, the process in which a molecular compound reacts with water and forms ions.
