  • The most expensive metal in the world

    Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

  • 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...

  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.



Most Popular

Canal Ray

Stream of positively charged particles (cations) that moves toward the negative electrode in cathode ray tubes, observed to pass through canals in the negative electrode.

Functional Group

A group of atoms that represents a potential reaction site in an organic compound.

Hydrogenation

The reaction in which hydrogen adds across a double or triple bond.

Primary Voltaic Cells

Voltaic cells that cannot be recharged, no further chemical reaction is possible once the reactants are consumed.

Secondary Voltaic Cells

Voltaic cells that can be recharged, original reactanats can be regenerated be reversing the direction of the current flow.

Bonding Orbital

A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.

Sulfuric Acid

H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.

Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.

Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.

xylidine

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

Coordination Isomers

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

Coordination Sphere

The metal ion and its coordinating ligands but not any uncoordinated counter-ions.
