Solid and liquid nitrogen

open access: yesPhysics Reports, 1976
Abstract Condensed nitrogen, one of the simplest molecular systems, has been the focus of vigorous and productive study in recent years. This paper reviews the experimental and theoretical literature on nitrogen giving primary emphasis to the solid state, although some attention is devoted to the liquid phase also.

Liquid nitrogen fertilization on the yield and phenologic variables of narrow-row cotton

open access: yesBioscience Journal, 2020
Slow-release liquid nitrogen fertilizer sources have been around since 1970. However, this technique is not widely used in the field, probably due to the low cost per ton of nitrogen in the solid form.

Liquid nitrogen for cryotherapy [PDF]

open access: yesBritish Journal of General Practice, 2012
The West Lothian Community Health and Care Partnership along with the local pharmacy department have unilaterally decided that they will no longer supply practices with liquid nitrogen for cryotherapy. The liquid nitrogen had been supplied for over 20 years to our practice.

Mechanical Properties of High-Temperature Granite under Liquid Nitrogen Cooling

open access: yesGeofluids, 2023
The cooling characteristics of liquid nitrogen can effectively weaken the mechanical properties of dry hot rock reservoirs, improve the porosity and permeability of dry hot rock, and thus improve the development and utilization of geothermal resources ...
