While niobium dust is an eye and skin irritant and a potential fire hazard, elemental niobium on a larger scale is physiologically inert (and thus hypoallergenic) and harmless.

It differs considerably among species anatomically, chemically, and physiologically.

The target synapse of the postganglionic neuron is mediated by adrenergic receptors and is activated by either norepinephrine (noradrenaline) or epinephrine (adrenaline).

All of this effort results in an inert object.

It is a lightweight inexpensive oil that is odorless and tasteless.

A well known but minor use is as a lifting gas in balloons and airships.

Because if you don't have that sameness, physiologically, you're going to be sick or you're going to die.

Cyclamates are used outside the U.S., but have been prohibited in the U.S. since 1969.

again, give each species what it wants, let it realize its desires, its physiological distinctiveness.

How does the Sun reach out across empty inert space and exert influence?

In many applications, the noble gases are used to provide an inert atmosphere.

They can also be used to couple a bio inert layer on a titanium implant.

And this is really bad news because plastic is not an inert substance.

More and more of the inert matter of the globe is being touched and animated by life.

He uses tiny bottles, the glass is tinted, he tops the olive oil off with an inert gas.

You become whatever it is that will freeze you, numb you and protect you from doubt or change.

Molten metal must be kept in a vacuum or an inert atmosphere to avoid reaction with air.

Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species.

In relatively old, very massive stars, a large core of inert iron will accumulate in the center of the star.

Floyd adds that it has remained completely inert, except for a single, very powerful radio emission aimed at Jupiter.

Denitrification Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle.

One of our collaborators is chemist Martin Hanczyc, and he's really interested in the transition from inert to living matter.

In raft solution culture, plants are placed in a sheet of buoyant plastic that is floated on the surface of the nutrient solution.

And what they've demonstrated is that people who report being more politically conservative are also more physiologically aroused when you show them disgusting images like the ones that I showed you.

Other types of chlorine compounds are rare in living organisms, and artificially produced chlorinated organics range from inert to toxic.

Now helium's a gas, there're a lot of reasons why helium's good, it's a tiny molecule, it's inert, it doesn't give you narcosis.

And instead of using human figures to develop ideas of time and space, I work in the mineral world. I work with more or less inert matter.

Solid argon is also used for the study of very unstable compounds, such as reactive intermediates, by trapping them in an inert matrix at very low temperatures.

Later, also in Avengers , the Intelligencia, a cabal of super intelligent supervillains, discover the inert body of a Galadorian Spaceknight and attempt to reactivate its powersource, hoping to exploit it.

Tungsten has also been used in Dense Inert Metal Explosives, which use it as dense powder to reduce collateral damage while increasing the lethality of explosives within a small radius.

Chemically, muonic helium, possessing an unpaired valence electron, can bond with other atoms, and behaves more like a hydrogen atom than an inert helium atom.

Its high melting point also makes tungsten suitable for aerospace and high temperature uses such as electrical, heating, and welding applications, notably in the gas tungsten arc welding process (also called tungsten inert gas (TIG) welding).

For example, it is possible for sodium cations to be reduced at a mercury cathode to form sodium amalgam, while at an inert electrode (such as platinum) the sodium cations are not reduced.

In terms of fabrication, all welding of titanium must be done in an inert atmosphere of argon or helium in order to shield it from contamination with atmospheric gases such as oxygen, nitrogen, or hydrogen.

The highly corrosive gas uranium hexafluoride would have to be used, as no substitute could be found, and the motors and pumps would have to be vacuum tight and enclosed in inert gas.

What the essence of that is, is that we're taking the sand at our feet, the inert silicon at our feet, and we're breathing a level of complexity into it that rivals that of life itself, and may even surpass it.

For instance, in the case of iodine being distributed between water and an inert organic solvent such as carbon tetrachloride then the presence of iodide in the aqueous phase can alter the extraction chemistry.

In the mid 1990s, Janssen Pharmaceutica developed and introduced into clinical trials the Duragesic patch, which is a formation of an inert alcohol gel infused with select fentanyl doses, which are worn to provide constant administration of the opioid over a period of 48 to 72 hours.

Powders of plutonium, its hydrides and certain oxides like Pu2O3are pyrophoric, meaning they can ignite spontaneously at ambient temperature and are therefore handled in an inert, dry atmosphere of nitrogen or argon.

The PUREX process that is commonly used in nuclear reprocessing uses a mixture of tri n butyl phosphate and an inert hydrocarbon (kerosene), the uranium(VI) are extracted from strong nitric acid and are back extracted (stripped) using weak nitric acid.

Its name is derived from the Old Norse word nár , meaning corpse , in reference to the animal's greyish, mottled pigmentation, like that of a drowned sailor and its summer time habit of lying still at or near the surface of the sea (called logging ).

Syrian opposition groups beg for the kinds of weapons needed to fight President Bashar al Assad s planes, defend hard won territory, provide safety for civilians, and signal to Assad that the world will not stand by as he does whatever it takes to subdue his own people.

In 1906, William D. Coolidge filed a patent for rendering molybdenum ductile, leading to its use as a heating element for high temperature furnaces and as a support for tungsten filament light bulbs oxide formation and degradation require that molybdenum be physically sealed or held in an inert gas.

Although elemental platinum is generally unreactive, it dissolves in hot aqua regia to give aqueous chloroplatinic acid (H2PtCl6) Pt 4 HNO3 6 HCl H2PtCl6 4 NO2 4 H2OAs a soft acid, platinum has a great affinity for sulfur, such as on dimethyl sulfoxide (DMSO) numerous DMSO complexes have been reported and care should be taken in the choice of reaction solvent.
