Method by which hydrophobic (water-repelling) particles of an ore are separated from hydrophilic (water-attracting) particles of a metallurgical pretreatment process.
- 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 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...
- 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?
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
A common type of dry cell.
Forces between individual particles (atoms, molecules, ions) of a substance.
A measure of the relative tendency of an atom to attract electrons to itself when chemically combined with another atom.
The substance that reduces another substance and is oxidized.
The basic unit used to describe the intensity of radioactivity in a sample of material. One curie equals 37 billion disintegrations per second or approximately the amount of radioactivty given off by 1 gram of radium.
Ideal Gas Law
The product of pressure and the volume of an ideal gas is directly proportional to the number of moles of the gas and the absolute temperature.
Theory of reaction rates that states that effective collisions between reactant molecules must occur in order for the reaction to occur.
A heterogeneous mixture in which solute-like particles do not settle out.
A measure of the intensity of heat, i.e. the hotness or coldness of a sample. or object.
The unit used to express dipole moments.
Physical properties of solutions that depend upon the number but not the kind of solute particles present.
Method of dating ancient objects by determining the ratio of amounts of mother and daughter nuclides present in an object and relating the ratio to the object?s age via half-life calculations.
It is the force in dynes acting along the surface of the liquid 1cm in length and perpendicular to it.
Benzene and its derivatives.
A mixture that does not have uniform composition and properties throughout.
Hydrated sulfates of the general formula M+M3+(SO4)2.12H2).
An impure form of carbon obtained by destructive distillation of coal or petroleum.
Substances consisting largely of hydrocarbons, derived from decay of organic materials under geological conditions of high pressure and temperature (metamorphism) include coal, petroleum, natural gas, peat and oil shale. For further information see Fuel Chemistry
A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
Reaction in which two substances (elements or compounds) combine to form one compound.
