Niobium

Niobium is a ductile transition metal. It is found in the minerals pyrochlore, the main commercial source for niobium, and columbite. It is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials. Other applications of niobium include its use in welding, nuclear industries, electronics, optics, numismatics and jewelry. In the last two applications, niobium's low toxicity and ability to be colored by anodization are particular advantages.

Nitric Oxide

Nitric Oxide is a free radical. It is an important intermediate in the chemical industry. Nitric oxide is a by-product of combustion of substances in the air, as in automobile engines, fossil fuel power plants, and is produced naturally during the electrical discharges of lightning in thunderstorms. It is a powerful vasodilator with a short half-life of a few seconds in the blood. Nitric oxide in the air may convert to nitric acid, which has been implicated in acid rain. Nitric oxide can be used for detecting surface radicals on polymers. Nitric oxide is one of the few gaseous signaling molecules known and is additionally exceptional due to the fact that it is a radical gas. It is a key vertebrate biological messenger, playing a role in a variety of biological processes. Nitric oxide is a known bioproduct in almost all types of organisms, ranging from bacteria to plants, fungi, and animal cells. Nitric oxide, known as the 'endothelium-derived relaxing factor', or 'EDRF', is biosynthesized endogenously from L-arginine, oxygen, and NADPH by various nitric oxide synthase (NOS) enzymes. It contributes to vessel homeostasis by inhibiting vascular smooth muscle contraction and growth, platelet aggregation, and leukocyte adhesion to the endothelium. Nitric oxide is also generated by phagocytes as part of the human immune response.

Nitrobenzene

Nitrobenzene is an organic compound. It is produced on a large scale as a precursor to aniline. Although occasionally used as a flavoring or perfume additive, nitrobenzene is highly toxic in large quantities. In the laboratory, it is occasionally used as a solvent, especially for electrophilic reagents. It is also used in shoe and floor polishes, leather dressings, paint solvents, and other materials to mask unpleasant odors. A significant merchant market for nitrobenzene is its use in the production of the analgesic paracetamol. It is also used in Kerr cells, as it has an unusually large Kerr constant.

Nitrogen

Nitrogen is a inert diatomic gas at standard conditions. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates, and cyanides, contain nitrogen. It occurs in all living organisms, and the nitrogen cycle describes movement of the element from air into the biosphere and organic compounds, then back into the atmosphere. It is a constituent element of amino acids and thus of proteins and nucleic acids. It resides in the chemical structure of almost all neurotransmitters, and is a defining component of alkaloids, biological molecules produced by many organisms.

Nitrogen Dioxide

Nitrogen dioxide is a chemical compound. It is an intermediate in the industrial synthesis of nitric acid. It has been used as a catalyst in certain oxidation reactions, as an inhibitor to prevent polymerization of acrylates during distillation, as a nitrating agent for organic compounds, as an oxidizing agent, as a rocket fuel, as a flour bleaching agent and in increasing the wet strength of paper.

Nitroglycerin

Nitroglycerin is a explosive liquid obtained by nitrating glycerol. Since the 1860s, it has been used as an active ingredient in the manufacture of explosives, specifically dynamite, and as such is employed in the construction and demolition industries. Similarly, since the 1880s, it has been used by the military as an active ingredient, and a gelatinizer for nitrocellulose, in some solid propellants, such as Cordite and Ballistite. It is also used medically as a vasodilator to treat heart conditions, such as angina and chronic heart failure. It is one of the oldest and most useful drugs for treating heart disease by shortening or even preventing attacks of angina pectoris.
