The engineering calculation and simulation of absorption refrigeration systems require the availability of simple and efficient functions for the determination of thermodynamic property values of the operating fluid. This work presents a set of five simple and explicit functions for the determination of the vapor - liquid equilibrium properties of the ammonia-water mixture. The functions are co...

Model halogenated aromatic and aliphatic hydrocarbons and halogenated phenols were dehalogenated in seconds by solvated electrons generated from sodium in both anhydrous liquid ammonia and ammonia/water solutions. The minimum sodium required to completely dehalogenate these model compounds was determined by increasing the Na/substrate ratio until halogen loss was complete. Minimum sodium consum...

The individual concentrations of each of these substances could provide useful insight to the health condition of the entire body. Am...

The structure of the crystalline ammonia-bearing phase formed when ammonia monohydrate liquid is compressed to 3.5(1) GPa at ambient temperature has been solved from a combination of synchrotron x-ray single-crystal and neutron powder-diffraction studies. The solution reveals that rather than having the ammonia monohydrate (AMH) composition as had been previously thought, the structure has an a...

Nitrification is a fundamental component of the global nitrogen cycle and leads to significant fertilizer loss and atmospheric and groundwater pollution. Nitrification rates in acidic soils (pH < 5.5), which comprise 30% of the world's soils, equal or exceed those of neutral soils. Paradoxically, autotrophic ammonia oxidizing bacteria and archaea, which perform the first stage in nitrification,...

Fertigation is herein defined as the application of solid or liquid (fluid) mineral fertilizers via pressurized irrigation systems, thus forming nutrient containing irrigation water. Although the practice of fertigation only started commercially in the mid 20th century, there is evidence that the concept of irrigation with dissolved nutrients was well known in the past. The first reported examp...

Abstract The Red Squirrel ammonia field experiments were conducted at the DNV Spadeadam site in UK 2022. Field test data currently exists for high‐pressure (ambient temperature) two‐phase releases of from Desert Tortoise (1983) and FLADIS (1996) experiments. No tests have ever been done cold (refrigerated) liquid spills on dry land or into water. handling liquified ammonia, during storage/proce...
