Halogen bonding (XB) is the non covalent interaction that occurs between a halogen atom (Lewis acid) and a Lewis base.

And it does have tungsten, a little bit of tungsten, left over, that's the kind of mine it was.

Future ozone concentrations are mainly driven by the changes in stratospheric halogen loading, with ozone recovery occurring after the peak of halogen loading.

You have to drill penetration of tungsten steel,

It's called the Pole Adit. And it does have tungsten, a little bit of tungsten, left over, that's the kind of mine it was.

After penetration, the projectile detonates Tungsten flipping through the concrete.

H is the hydrogen atom involved in hydrogen bonding (HB), and X is the halogen atom involved in XB.

The response to a bad idea like, say, a tungsten light bulb is a better idea. OK?

Clinical trials have demonstrated that among these three options, halogen light is the best source for producing optimal treatment results.

And then what about us? We, the higher elements we, made out of oxygen, carbon, nitrogen, tungsten, iron.

There are also important mineral resources, including zinc, tin and tungsten, as well as rare ores such as antimony.

The environmentalists put their money on chromium, copper, nickel, tin, and tungsten, and picked a time frame of 10 years.

H A and X A, when both atoms are considered together, are called hydrogen halogen bond donors, accordingly, and D is HB XB acceptor.

Other commodity related meetings held under UNCTAD auspices at Geneva from March to May 1994 dealt with iron ore, tungsten and bauxite.

Studies investigating the dynamical coupling between the upper troposphere and lower stratosphere, particularly as it applies to water vapour, short lived halogen species, and ozone.

If the acid is a carboxylic acid, the compound contains a COX functional group, which consists of a carbonyl group singly bonded to a halogen atom.

In fact, for several of the metals, such as manganese, iron, copper, zinc and tungsten, average prices in January June 1994 were still below 1993 levels.

Indeed, in real terms the current prices of tin, tungsten, antimony, coffee, rubber and petroleum are even lower than they were in 1930, during the great depression.

Furthermore, the Special Committee on Preferences and the three Intergovernmental Groups of Experts on Restrictive Business Practices, Tungsten and Iron Ore have continued with their existing mandates.

There are also substantial deposits of gold (Uzbekistan was the second largest producer of gold in the former Soviet Union), silver, copper, lead, zinc, wolframite and tungsten.

Then, most of the explosion, the penetration of tungsten steel actually penetrated to the end there is no doubt and then hit this concrete block and continued

Armor Piercing (AP) A hard bullet made from steel or tungsten alloys in a pointed shape typically covered by a thin layer of lead and or a copper or brass jacket.

Alloyed steels, which are sometimes also called special steels and may be considered specialty products, contain small portions of alloying elements such as chromium, cobalt, manganese, molybdenum, nickel, niobium, silicon, tungsten or vanadium.

For example, the authors of The Limits to Growth predicted that before 2013, the world would have run out of aluminum, copper, gold, lead, mercury, molybdenum, natural gas, oil, silver, tin, tungsten, and zinc.

When the equipment's halogen lamps, worth 12 per unit, had been used up, a professor tried to obtain new lamps from the company in Spain, but this was refused once it was discovered that she was of Cuban nationality.

11.1.1 Although considerable progress has been made over the last decade in understanding the role of halogen chemistry in stratospheric ozone loss, there are a number of uncertainties whose resolution define the need for present and future observations and research.

Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group R N2 X where R can be any organic residue such alkyl or aryl and X is an inorganic or organic anion such as a halogen.

Other chemical differences between these two groups include the nature of heteroatoms (O and N enriched in natural products, and S and halogen atoms more often present in synthetic compounds), as well as level of non aromatic unsaturation (higher in natural products).

(a) Annual and quarterly statistical bulletins on tungsten and tin annual and, with the assistance of a trust fund, quarterly statistical publications on iron ore and annual statistics on bauxite alumina aluminium (all the issues for 1993 have been published)

That message still resonates today, though it was spectacularly wrong. For example, the authors of The Limits to Growth predicted that before 2013, the world would have run out of aluminum, copper, gold, lead, mercury, molybdenum, natural gas, oil, silver, tin, tungsten, and zinc.

Theoretically, all five can decay into isotopes of element 72 (hafnium) by alpha emission, but only 180W has been observed ref to do so with a half life of (1.8 0.2) 1018 years on average, this yields about two alpha decays of 180W in one gram of natural tungsten per year.
