Ionic biography, Ionic discography
There are two lesser orders, the stocky Tuscan order and the rich variant of Corinthian, the Composite order, added by 16th century Italian architectural theory and practice.The Ionic order column was being practiced in mainland Greece in the 5th century BC.It was in the great sanctuary of the goddess: it could scarcely have been in a more prominent location for its brief lifetime.Ionic temple was the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World.Unlike the Greek Doric order column, Ionic columns normally stand on a base which separates the shaft of the column from the stylobate or platform.The capital of the Ionic column has characteristic paired scrolling volutes that are laid on the molded cap ("echinus") of the column, or spring from within it.Originally the volutes lay in a single plane (illustration at right); then it was seen that they could be angled out on the corners.This feature of the Ionic order made it more pliant and satisfactory than the Doric to critical eyes in the 4th century BC: angling the volutes on the corner columns, ensured that they "read" equally when seen from either front or side facade.Scamozzi's version became so much the standard, that when a Greek Ionic order was eventually reintroduced, in the later 18th century Greek Revival, it conveyed an air of archaic freshness and primitive, perhaps even republican, vitality.Ionic capitals on a neoclassical Cincinnati life insurance headquarters.Below the volutes, the Ionic column may have a wide collar or banding separating the capital from the fluted shaft, as at Castle Coole (below, right).After a little early experimentation, the number of hollow flutes in the shaft settled at 24.Roman fluting leaves a little of the column surface between each hollow; Greek fluting runs out to a knife edge that was easily scarred.Arts architect John Russell Pope wanted to convey the manly stamina combined with intellect of Theodore Roosevelt, he left colossal Ionic columns unfluted on the Roosevelt memorial at the American Museum of Natural History, New York, for an unusual impression of strength and stature.The major features of the Ionic order are the volutes of its capital, which have been the subject of much theoretical and practical discourse, based on a brief and obscure passage in Vitruvius.Ionic order, in the area where the Doric order is articulated with triglyphs.Roman and Renaissance practice condensed the height of the entablature by reducing the proportions of the architrave, which made the frieze more prominent.Vitruvius, a practicing architect who worked in the time of Augustus, reports (De Architectura, iv) that the Doric has a basis of sturdy male body proportions while Ionic depends on "more graceful" female body proportions.Renaissance architectural theorists took his hints, to interpret the Ionic Order as matronly in comparison to the Doric Order, though not as wholly feminine as the Corinthian order.Renaissance libraries and courts of justice, learned and civilized.Because no treatises on classical architecture survive earlier than that of Vitruvius, identification of such "meaning" in architectural elements as it was understood in the 5th and 4th centuries BC remains tenuous, though during the Renaissance it became part of the conventional "speech" of classicism.The Parthenon, although it conforms mainly to the Doric order, also has some Ionic elements.Ionic mode to be seen on the Athenian Acropolis is exemplified in the Erechtheum.From the 17th century onwards, a much admired and copied version of Ionic was that which could be seen in the temple called that of "Fortuna Virilis" in Rome, first clearly presented in a detailed engraving in Antoine Desgodetz, Les edifices antiques de Rome (Paris 1682).Greek Revival "idea of primitivism, of searching back to the true, untainted sources of architectural beauty" (p.Massey and Shirley Maxwell, "Greek Revival in

(room temperature ionic liquids, RTIL's).At least one ion has a delocalized
charge and one component is organic, which prevents the formation of a stable
crystal lattice.The methylimidazolium and pyridinium ions have proven to be good starting
points for the development of ionic liquids:
Properties, such as melting point, viscosity, and solubility of starting
materials and other solvents, are determined by the substituents on the organic
component and by the counterion.Many ionic liquids have even been developed for
specific synthetic problems.This RTIL is not water stable.The catalyst and ionic liquid may be recycled several times.Ionic liquids can also make for safer
microwave synthesis methods, because
sudden pressure surges are not possible.The dipole characteristics of ionic
liquids translate into rapid excitation by microwaves, and consequently faster

Organic Reactions
Org.Ionic compounds are basically defined as
being compounds where two or more ions are held next to each other by electrical
attraction.One of the ions has a positive charge (called a "cation") and
the other has a negative charge ("anion").Think back to grade school: The same thing that makes the positive
and negative ends of a magnet stick to each other is what makes cations
and anions stick to each other.Usually, when we have ionic compounds,
they form large crystals that you can see with the naked eye.So, what are the main properties of salts?All ionic compounds form crystals.Again, salts like to
form crystals because when you have a whole bunch of little electrical
positive and negative charges all stuck together, they seem to like to
bunch into little stacking groups.There
are ten or so different general shapes of unit cells.When you get to graduate
school, ask me about them.For high school classes, it's really not all
that important.Ionic compounds tend to have high melting
and boiling points.Most of the time, when you work with ionic compounds in a chemistry class,
the melting point is hot enough that you can't melt them with a Bunsen
burner.Well, it has to do
with the way that ionic materials are held together.Remember how we said
above that ionic compounds form crystals?Ionic compounds are very hard and very
brittle.Again, this is because of the way that they're held together.Above, we said that it takes a lot of energy to break the positive and
negative charges apart from each other.This also explains the brittleness of ionic compounds.It takes a lot of energy to pull ionic charges apart from each other.However,
if we give a big crystal a strong enough whack with a hammer, we usually
end up using so much energy to break the crystal that the crystal doesn't
break in just one spot, but in a whole bunch of places.Instead of a clean
break, it shatters.Ionic compounds conduct electricity when
they dissolve in water.If we take a salt and dissolve it in water,
the water molecules pull the positive and negative ions apart from each
other.Dissolved salts are the same
way.Because the ions are stuck in one place due to the structure of the crystal,
the electricity doesn't move around very well.Another good question:
"Does water without salt in it conduct electricity?"The answer: Not very
well.Some of the crud is ionic, so when the dryer hits the water,
they get zapped.An interesting "thought experiment" would be to wash all
the salt off yourself and then drop a hairdryer in the bathtub with you.In real life, you'd still become a crispy
critter because tap water by itself has ionic compounds dissolved in it
anyway.If you put a hairdryer in the bathtub with you under ANY conditions, you
will fry yourself!How do we name
ionic compounds?For practice problems with complete solutions,
click here.Most ionic compounds (and any I would
ever give on a test) have two word names.There
is no exception to this rule.The best way to go about naming ionic compounds
is to take a look at the formula and figure out the names of the cation
and anion.When you've got that, just stick them together and you've got
the name of the compound.So, how do we name cations?So, the Na+ ion is the "sodium" ion.For example, iron can have a charge of either +2 or +3.When you've done this, just put the number after the name of the element
in Roman numerals.For example, the Fe+3 ion just has the name
"iron (III)".If the anion has more than one atom, then we'd
say that it's a "polyatomic ion", meaning (not surprisingly) that the anion
has more than one atom.Look up the polyatomic ion in a table (or pull
it out of your...Generally, if one of these ions has more than one atom in
it, you'll need to look it up in a chart.If you don't
know the formulas, look 'em up.If the cation in the compound you're naming
is not a transition metal, then you definitely don't need to use a Roman
numeral and the naming is done.If there is, then you need to figure out
whether or not the cation can exist in more than one charge.If not, then
you don't need a Roman numeral.Step Three: Figure out what the Roman
numeral should be
Basically, this should be fairly easy.Since iron
has a charge of +3 in this compound, the name in this example is iron
(III) sulfate.Is +3 a charge that iron can
have?If we solve the problem
using the first three steps, we find that the formula should be iron (I)
sulfide.When this happens, look at the anion.Since iron has a charge of +2, the name of the
compound is iron (II) sulfide.We'll use an example to find the formula
of an ionic compound: copper (II) fluoride
Step One: Translate the name into the
ions
In copper (II) fluoride, the cation is
the copper (II) ion and the anion is the fluoride ion.If not, then you need to go back and review the rules for naming
ions above.Step Two: Put brackets around the ions,
but leave the charges on the outside.Never
change anything in these brackets, ever!Step Three: Put the ions next to each
other.Exceptions:
IF the charges on the ions can be divided
by the same number, then do it before you do step four.For example, if
you were to find the formula for manganese (IV) oxide, you'd realize in
step three that both manganese (IV) and oxygen have charges that can be
divided by two.IF we have a polyatomic ion, such as sulfate
or ammonium, you need to replace the brackets with parentheses in step
five.Ionic compounds are usually formed when metal
cations bond with nonmetal anions.If you have two neutral elements, and one wants
to gain electrons to be like the nearest noble gas and the other wants
to lose electrons to be like the nearest noble gas, chances are that they
will react with each other and make an ionic compound.Is the dust and polluted air getting to you?Using no annoying fan or HEPA air filters, its silent operation is efficient in cleaning the room of airborne particles.Uses only 6 watts, this air purifier is designed to run 24 hours a day!Relieved from the general symptoms caused by stress, pollutants in the city and have more concentration ability.Excellent in sterilization of bacteria germs, etc as vitamin c is a acidity nature.Clean wastes in skin pores, as vitamin is absorbed easily into the skin during shower.Relieve modern people's mental stress, anger, overwork, fatigue and etc.Higher effect of negative ion than deep in the forest.Filter for particles including dust and mold spores.Air Purifiers 2 weeks ago.Both our cars were covered in ash.The air is fresh and clean.The NeoTech units were great for keeping the air in the house breathable.And one other story for you.Last week I was doing double sided printing.When you print the flip side all the pages stick together because of the static they built the first time they fed through the printer.We have a perfect solution for you.Ionic Air Purifier Campare to Ionic Breeze03.UV Ionic Air Purifier with Germicidal UVLamp04.
