inert: Encyclopedia II - ChromiumIII chloride - Chemical properties

Chromium(III) chloride is a Lewis acid, classified as "hard" according to the Hard-Soft Acid-Base theory. However it is also a chloro complex which is quite inert to substitution, so in fact it is ordinarily quite unreactive. The low reactivity of the d3 Cr3+ ion can be explained using crystal field theory. One way of opening CrCl3 up to substitution in solution is to reduce even a trace amount to CrCl2, for example using zinc in hydrochloric acid. This chromium(II) compound undergoes substi ...

inert: Encyclopedia II - Fullerene - Possible dangers

Although buckyballs have been thought in theory to be relatively inert, a presentation given to the American Chemical Society in March 2004 and described in an article in New Scientist on April 3, 2004, suggests the molecule is injurious to organisms. An experiment by Eva Oberdörster at Southern Methodist University, which introduced fullerenes into water at concentrations of 0.5 parts per million, found that largemouth bass suffered a 17-fold increase in cellular damage in the brain tissue after 48 hours. The damage was of the type lipid p ...

inert: Encyclopedia II - Bipropellant rocket - Principle of operation

Bipropellant rockets have to introduce the propellants into the chamber at high pressure, mixing them well to give stable and thorough combustion and stop the chamber from melting. As propellants need to leave the tanks at sufficiently high rate they are stored under pressure. The propellants are frequently stored as liquids for maximum density; gaseous storage can be used but is rarely employed as the tanks are inevitably heavy. Liquid propellants are pressurised by a pressurant gas, either an inert one, often heli ...

inert: Encyclopedia II - Shaped charge - Explosive lenses

Explosive lenses used in nuclear weapons are highly specialised shaped charges. They are used to change the approximately spherical diverging detonation wave into a spherical converging one. The converging wave is then used to collapse the various shells (tamper, reflector, pusher, etc) and finally compresses the core (pit) to a super-critical state. They are (usually) machined from a plastic bonded explosive (PBX) and an inert insert, sometimes called a wave shaper, which is often a high density foam or plastic, though many other material c ...

inert: Encyclopedia II - Rhodium - Occurrence

The industrial extraction of rhodium is complex as the metal occurs in ores mixed with other metals such as palladium, silver, platinum, and gold. It is found in platinum ores and obtained free as a white inert metal which it is very difficult to fuse. Principal sources of this element are located in South Africa, in river sands of the Ural Mountains, in North and South America and also in the copper-nickel sulfide mining area of the Sudbury, Ontario region. Although the quantity at Sudbury is very small, the large amount of nickel ore proce ...

Main Article: Rules of Quidditch Quidditch is played on a long oval field with three goal hoops on posts at each end. The team that scores the most points wins. There are seven players to a team: one Keeper, two Beaters, three Chasers, and a Seeker. They play with four balls. The Quaffle is inert and the equivalent to the one ball used in many Muggle games, though it has a charm placed on it so that it slows as it falls and to make it easier to hold. Chasers handle it, trying to throw it through one of the hoops o ...

inert: Encyclopedia II - Radon - Notable characteristics

Essentially chemically inert, but radioactive, radon is the heaviest noble gas and one of the heaviest gases at room temperature. (The heaviest is Uranium hexafluoride, UF6.) At standard temperature and pressure radon is a colorless gas but when it is cooled below its freezing point it has a brilliant phosphorescence which turns yellow as the temperature is lowered and orange-red at the temperature air liquefies. Natural radon concentrations in Earth's atmosphere are so low that natural waters in contact with the atmosphere ...

inert: Encyclopedia II - AGM-78 Standard ARM - Variants

An inert training version of the AGM-78A was built as ATM-78A. Of equal size, mass and shape, the missile lacked a seeker head, warhead, or propulsion systems and was essentially just a dead weight. An A2 model introduced a Bomb Damage Assessment (BDA) capability and an SDU-6/B phosphorus target marker flare to facilitate targeting of the site for follow up attacks. In 1969 an improved model called the AGM-78B was produced. This featured a broadband seeker which allowed the missile to be used against a much wider variety of tar ...

inert: Encyclopedia II - Salt bridge - Filter paper bridges

The other type of salt bridges consists of a filter paper, also soaked with a relatively inert electrolyte, usually potassium chloride or sodium chloride. No gelification agent is required as the filter paper provided a solid medium for conduction. Conductivity of this kind of salt bridges depends on a number of factors: the concentration of the electrolyte solution, the texture of the filter paper and the absorbing ability of the filter paper. Generally a smoother texture and a higher absorbancy contributes to a higher conductivity. A porous disk between the two half-cells may be used instead of a salt bri ...

inert: Encyclopedia II - Raney nickel - Safety

Due to its large surface area and high volume of contained hydrogen gas, dry, activated Raney nickel is a pyrophoric material that should be handled under an inert atmosphere. Raney nickel is typically supplied as a 50% slurry in water. Care should be taken never to expose Raney nickel to air. Even after reaction, Raney nickel contains significant amounts of hydrogen gas, and will ignite when exposed to air. Raney nickel will produce hazardous fumes when burning, and therefore the use of a gas mask is recommended when extinguishing fi ...

inert: Encyclopedia II - Wave soldering - Soldering

The tank of molten solder has a pattern of standing waves (or, in some cases, intermittent waves) on its surface. When the PCB is moved over this tank, the solder waves contact the bottom of the board, and stick to the solder pads and component leads via surface tension. Precise control of wave height is required to make sure solder is applied to all areas but does not splash to the top of the board or other undesired areas. This process is sometimes performed in an inert gas atmosphere to incre ...

inert: Encyclopedia II - Poly vinyl pyrrolidone - Uses

The monomer is carcinogenic and is extremely toxic to aquatic life. However the polymer PVP in its pure form is so safe that not only is it edible by humans, it was used as a blood plasma expander for trauma victims after the first half of 20th century. It is used as a binder in many pharmaceutical tablets; being completely inert to humans, it simply passes through. PVP added to Iodine forms a complex; in solution it is known under the trade name Betadine. PVP binds to polar molecules exceptionally well, owing to its polarity. This has led to its application in coatings for photo-quality ink-jet papers and transpar ...

inert: Encyclopedia II - RBMK - Containment

The RBMK design includes several kinds of containment needed for normal operation. There is a sealed metal containment structure filled with inert gases surrounding the reactor to keep oxygen away from the graphite (which is normally at about 700 degrees Celsius). There is also a large amount of shielding to absorb radiation from the reactor core. This includes a concrete slab on the bottom, sand and concrete around the sides, and a large concrete slab on top of the reactor. Much of the reactor's internal machinery is attached to this ...

inert: Encyclopedia II - Petrushka - Story

The play opens up at a carnival/fair, called Shrovetide, (the Russian Maslenitsa - akin to Mardi Gras) which is a celebration a few days prior to a long religious fast. The people rejoice before the long fast when they won’t be able to enjoy themselves for a while. Stravinsky's orchestration and rapidly changing rhythms depict the hustle and bustle of the fair. An organ grinder and dancing girl entertain the crowd. Drummers announce the appearance of the Old Wizard, who charms the captivated audience. Suddenly, the curtain rises on a tiny theater, as the Wizard introduces the inert, lifeless puppet figures of Petrushka, the ...

inert: Encyclopedia II - Pebble bed reactor - Basic design

The reactor provides heat, which is used to turn a generator. However, there are a number of different design choices. The uranium, thorium or plutonium nuclear fuels are in the form of a ceramic (usually oxides or carbides) contained within spherical pebbles made of pyrolytic graphite (see discussion below). The pebbles are in a bin or can. An inert gas, helium, nitrogen or carbon dioxide, circulates through the spaces between th ...

inert: Encyclopedia II - Microchip implant animal - Components of a microchip

Microchips are passive, or inert, RFID devices and contain no internal power source. They are designed so that they do not act until acted upon. Three basic elements comprise most microchips: A silicon chip (integrated circuit); a core of ferrite wrapped in copper wire; and a small capacitor. The silicon chip contains the identification number, plus electronic circuits to relay that information to the scanner. The ferrite -- or iron -- core acts as a radio antenna, ready to receive a signal from the scanner. The ...

inert: Encyclopedia II - NaS battery - Operation

During the discharge phase, molten metallic sodium at the core acts as the anode, separated by a beta alumina cylinder from a sulfur container made from an inert metal acting as the cathode. The sulfur is absorbed in a carbon sponge. Alumina is a good conductor of sodium ions but a bad conductor of electrons, avoiding self discharge. When sodium gives off an electron, the Na+ ion migrates to the sulfur container. The electron travels through the molten sodium to the contact and through the electric load to the sulfur container. He ...

inert: Encyclopedia II - Gold - Occurrence

Due to its relative chemical inertness gold is usually found as the native metal or alloy. Occasionally large accumulations of native gold (also known as nuggets) occur but usually gold occurs as minute grains. These grains occur between mineral grain boundries or as inclusions within minerals. Common gold associations are quartz often as veins and sulfide minerals. The most common sulfide associations are pyrite, chalcopyrite, galena, sphalerite, arsenopyrite, stibnite and pyrrhotite. Rarer mineral associations are petzite, calaverite, sylvanite, mut ...

inert: Encyclopedia II - Decompression sickness - Introduction

Decompression sickness can happen in any of the following situations: A diver ascends from a dive. An unpressurized aircraft flies upwards. The cabin pressurization system of an aircraft fails. Divers flying in any aircraft after diving. Pressurized aircraft are not risk-free, since the cabin pressure is not maintained at sea-level pressure. A worker comes out of a pressurized caisson, or out of a mine, which has been pressurized to keep water out. This causes inert gases (mainly nitrogen), normally dissolved in body fluids and tissues, to ...

inert: Encyclopedia II - Breathing gas - Unwelcome components of breathing gases

Many gases are not suitable for use in diving breathing gases. Here is an incomplete list. Breathing gas - Argon. Argon (Ar) is an inert gas that is more narcotic than nitrogen, so is not suitable as a diving breathing gas. It is used for dry suit inflation because of its good thermal insulation properties. Argon is much more expensive than air. Breathing gas - Carbon dioxide. Carbon dioxide (CO2) is produced by the metabolism of the human body and causes carbon dioxide ...

inert: Encyclopedia II - Aristotle - Aristotle's critics

Aristotle has been criticised on several grounds. His analysis of procreation is frequently criticised on the grounds that it presupposes an active, ensouling masculine element bringing life to an inert, passive, lumpen female element; it is on these grounds that some feminist critics refer to Aristotle as a misogynist. At times, the objections that Aristotle raises against the arguments of his own teacher, Plato, appear to rely on faulty interpretations of those arguments. Although Aristotle advised, against P ...

inert: Encyclopedia II - Asgard Stargate - The Replicators

The Asgard have been largely unable to help Earth with their fight against the Goa'uld due to a war with a greater enemy, the Replicators. Asgard weapons had largely proven ineffective against Replicators because they were energy-based, which the Replicators were able to develop sophisticated technological countermeasures against. Human weapons, on the other hand, used simple chemical reactions to propel inert projectiles - a crude attack that proved difficult for the physically small and weak replicators to adapt to. SG-1 has provided assis ...
