A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.
- 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...
An artificially induced nuclear reaction caused by the bombardment of a nucleus with subatomic particiles or small nucei.
A colorless, crystalline pentose sugar, C5H10O5, derived from xylan, straw, corncobs, etc., by treating with heated dilute sulfuric acid, and dehydrating to furfural if stronger acid is used.
An atomic emission or absorption spectrum.
A very slightly soluble compound.
Complex species that contain ammonia molecules bonded to metal ions.
A solid characterized by a regular, ordered arrangement of particles.
Band of Stability
Band containing nonradioactive nuclides in a plot of number of neutrons versus atomic number.
The metal ion and its coordinating ligands but not any uncoordinated counter-ions.
A compound that contains more than one double bond per molecule.
Substances consumed in a chemical reaction.
An atom or group of atoms that contains one or more unpaired electrons (usually very reactive species)
Noble Gases (Rare Gases)
Elements of the periodic Group 0, also called rare gases, formerly called inert gases, He,Ne,Ar, Kr, Xe, Rn.
An atom or a group of atoms that carries an electric charge.
A system in which controlled nuclear fisson reactions generate heat energy on a large scale, which is subsequently converted into electrical energy.
Nuclide that is produced in a nuclear decay.
Short-lived species formed by the collision of dissolved ions of opposite charges.
To estimate the value of a result outside the range of a series of known values. Technique used in standard additions calibration procedure.
A substance capable of causing or producing cancer in mammals.
A relatively large energy separation between an insulator's highest filled electron energy band and the next higher energy vacant band. Beginning in the fourth energy level, a set of seven degenerate orbitals per energy level, higher in energy than s, p, and d orbitals of the same energy level.
Resistance offered by the molecules of a liquid to flow is termed as viscosity.
