Nitrogen Fixation $124.27 Nitrogen fixation usually refers to the biological process by which nitrogen (N2) in the atmosphere is converted into ammonia. This process is essential for life because fixed nitrogen is required to biosynthesize the basic building blocks of life, e.g. nucleotides for DNA and amino acids for proteins. Formally, nitrogen fixation also refers to other abiological conversions of nitrogen, such as its conversion to nitrogen dioxide. Nitrogen fixation is utilized by numerous prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria. Microorganisms that fix nitrogen are called diazotrophs. Some higher plants, and some animals (termites), have formed associations (symbiosises) with diazotrophs. Nitrogen fixation also occurs as a result of nonbiological processes. These include lightning, industrially through the HaberBosch Process, and combustion. Biological nitrogen fixation was discovered by the Dutch microbiologist Martinus Beijerinck.

Nitrogen Asphyxiation $90.81 High Quality Content by WIKIPEDIA articles Nitrogen asphyxiation is an occasional cause of accidental death and a theoretical method of capital punishment advocated in a National Review article, Killing with kindness capital punishment by nitrogen asphyxiation (Creque 1995). The painful experience of suffocation is not caused by lack of oxygen intake in humans, but rather because of a buildup of carbon dioxide in the bloodstream which is exhaled under normal circumstances. Because of this property, nitrogen in Dutch is called stikstof ( suffocation matter ). Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Nitrogen Trifluoride $78.07 High Quality Content by WIKIPEDIA articles Nitrogen trifluoride is the inorganic compound with the formula NF3. This nitrogenfluorine compound is a colorless, toxic, odourless, nonflammable gas. It finds increasing use as an etchant in microelectronics. Nitrogen trifluoride is used in the plasma etching of silicon wafers. Today nitrogen trifluoride is predominantly employed in the cleaning of the PECVD chambers in the high volume production of liquid crystal displays and siliconbased thin film solar cells. In these applications NF3 is initially broken down in situ, by a plasma. The resulting fluorine atoms are the active cleaning agents that attack the polysilicon,silicon nitride and silicon oxide. Nitrogen trifluoride can be used as well with tungsten silicide, and tungsten produced by CVD. NF3 has been considered as an environmentally preferable substitute for perfluorocarbons such as hexafluoroethane,sulfur hexafluoride etc... The process utilization of the chemicals applied in plasma processes is typically below 20 . Therefore some of the PFCs and also of the NF3 always escape into the atmosphere. Modern gas abatement systems can decrease such emissions. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Nitrogen Trichloride $70.1 High Quality Content by WIKIPEDIA articles Nitrogen trichloride, also known as trichloramine, trichlorine nitride (wrong in nomenclature of binary compounds; Nitrogen trichloride is a sound name following the rules of systematic nomenclature) is the chemical compound with the formula NCl3. This yellow, oily, pungentsmelling liquid is most commonly encountered as a byproduct of chemical reactions between ammoniaderivatives and chlorine (for example, in swimming pools between disinfecting chlorine and urea in urine from bathers). In pure form, NCl3 is highly reactive. Nitrogen trichloride can form in small amounts when public water supplies are disinfected with monochloramine, and at given levels it can irritate mucous membranes. Nitrogen trichloride was trademarked as Agene and used to artificially bleach and age flour. It has the same effect as that of tear gas, but has never been used as such.

Biological Nitrogen Fixation $510.15 Nitrogen fixation is a key component of the nitrogen cycle, one of the most fundamental cycles in the biosphere. Conversion of atmospheric nitrogen into organic nitrogen compounds can be carried out only by certain bacteria and bluegreen algae (cyanobacteria). Some nitrogen fixing bacteria live symbiotically with leguminous plants such as peas, beans, clover, and certain tropical trees in nodules on the plants roots, while others live independently in the soil and aquatic habitats. By the activity of these microorganisms, the soil is enriched with the nitrogen required for plant growth and function. Thus the topic is of considerable practical as well as fundamental importance. In Biological Nitrogen Fixation, the leading researchers in nitrogen fixation from all over the world contribute uptotheminute general reviews on all aspects of the subject, from the molecular biology and genetics to the biochemistry, physiology, and ecology of nitrogen fixation. This compendium of current research is an indispensable reference for all involved in nitrogen fixation research, and of use to all who deal indirectly with the subject. It will also serve as a thoroughly uptodate textbook for graduate students in microbiology, plant science, biochemistry, molecular biology, plant pathology, agronomy, and genetics.

Highlights of Nitrogen Fixation Research $348.89 This volume will cover recent advances in nitrogen fixation research, including genetic engineering to modify nitrogen fixation, modulation of key symbiotic metabolic pathways, cloning and developmental expression, drought stress effects on nitrogen fixation, differential expression of symbiosisrelated genes, use of TDNA tagging to identify plant genes used in symbiotic nitrogen fixation, functional genomics, and cloning in defined and mobilizable regions. The topics covered extend from basic aspects to agricultural applications, ranging from bacterial genetics and metabolism to plant genetics and physiology. Nitrogen fixation, a process which supports life on this planet, has attracted the interest of researchers for the past century. Nitrogen fixation is responsible for the conversion of inert dinitrogen (N2) gas from the atmosphere into usable ammonia, replacing the fixed nitrogen constantly being lost to the atmosphere by the denitrification process. Worldwide agricultural productivity is determined by the availability of fixed nitrogen in all its forms, and upon it a continually increasing human population depends for survival.

Active Laser Medium $68.51 High Quality Content by WIKIPEDIA articles The active laser medium is the source of optical gain within a laser. The gain results from the stimulated emission of electronic or molecular transitions to a lower energy state from a higher energy state previously populated by a pump source. Examples of active laser media include: Certain crystals, typically doped with rareearth ions or transition metal ions; most often yttrium aluminium garnet, yttrium orthovanadate, or sapphire; Glasses, e.g. silicate or phosphate glasses, doped with laseractive ions; Gases, e.g. mixtures of helium and neon, nitrogen, argon, carbon monoxide, carbon dioxide, or metal vapors; Semiconductors, e.g. gallium arsenide, indium gallium arsenide, or gallium nitride. In order to lase, the active gain medium must be in a nonthermal energy distribution known as a population inversion. The preparation of this state requires an external energy source and is known as laser pumping. Pumping may be achieved with electrical currents or with light, generated by discharge lamps or by other lasers. More exotic gain media can be pumped by chemical reactions, nuclear fission, or with highenergy electron beams.

LE N2 low pressure longitudinal nitrogen laser - the story (reload)

Calculate the energy of a photon of electromagnetic radiation at each of the following wavelengths.?

1)632.8nm (wavelength of red light from helium-neon laser)
2)12.24nm (wavelength of microwave oven)
3)337.1nm (wavelength of nitrogen laser)

This is something you need to learn. I will give you the example then you need to figure out the others.

equations: c = λ*v, where c = speed of light in a vacuum = 2.9979 x 10^8 m/s; λ = wavelength in meters; v = frequency in s^-1 or 1/s, also Hz, hertz.
Energy = E = hv = hc/λ, where h = planck's constant = 6.626 x 10^-34 J*s
NOTE: 1 J = 1 joule = 1 kg*m^2/s^2

1. λ = 632.8 nm(1 m)/(1 x 10^9 nm) = 6.328 x 10^-7 m
E = (6.626 x 10^-34 J*s)(2.9979 x 10^8 m/s)/(6.328 x 10^-7 m) = 3.155 x 10^-19 J
Do you see how all of the units cancel except the joules?

1st step: convert nm to m
2nd step: calculate energy

That's how you do it. Now let's see you do the next two.

Just keep on Truckin!!
