As per available reports about 42 Relevant Journals, 48 Conferences, 145 Workshops are presently dedicated exclusively to breathing disorder and about 91 articles are being published on Liquid Nitrogen.
Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. It is produced industrially by fractional distillation of liquid air. Liquid nitrogen is a dull clear liquid with density of 0.807 g/ml at its BP and a dielectric constant of 1.43. Liquid nitrogen is usually indicated to by the abridgement, LN2 or "LIN" or "LN" and has the UN number 1977. Liquid nitrogen is a diatomic liquid means the diatomic character of the covalent N bonding in N2 gas is retained even after condensation.
Liquid nitrogen can easily be transformed to a solid by setting it in a vacuum cubicle pumped by a rotary vacuum pump. Liquid nitrogen freezes at −210 °C; −346 °F. Despite its fame, liquid nitrogen's ability as a coolant is limited by the fact that it boils instantly on meeting with a warmer object, enveloping the matter in insulating nitrogen gas. This effect, referred as the Leidenfrost effect, applies to any liquid in contact with an object much hotter than its boiling point. Hastier cooling may be obtained by plunging an object into a slush of liquid and solid nitrogen rather than liquid nitrogen alone.
OMICS International Organizes 1000+ Global Events Every Year across USA, Europe & Asia with support from 1000 more scientific societies and Publishes 700+ Open access journals which contains over 100000 eminent personalities, reputed scientists as editorial board and organizing committee members. The conference series website will provide you list and details about the conference organize worldwide.
Scope and Importance:
Liquid nitrogen is the liquefied form of the element nitrogen that is commercially produced by fractional distillation of liquid air. Sometimes liquid nitrogen is denoted as LN2, LN, or LIN.Liquid nitrogen has the UN number 1977. At normal pressure, liquid nitrogen boils at 77 K (−195.8°C or −320.4°F). The liquid to gas expansion ratio of nitrogen is 1:694, which means liquid nitrogen boils to fill a volume with nitrogen gas very quickly.Nitrogen is non-toxic, odorless, and colorless. It is relatively inert. It is not flammable.Nitrogen gas is slightly lighter than air once it reaches room temperature. It is slightly soluble in water.
