Hydride vapour-phase epitaxy (HVPE) is an epitaxial growth technique often employed to produce semiconductors such as GaN, GaAs, InP and their related compounds, in which hydrogen chloride is reacted at elevated temperature with the group-III metals to produce gaseous metal chlorides, which then react with ammonia to produce the group-III nitrides.
A metal hydride can be a thermodynamically a weak acid and a weak H − donor; it could also be strong in one category but not the other or strong in both. The H − strength of a hydride also known as its hydride donor ability or hydricity corresponds to the hydride's Lewis base strength. Not all hydrides are powerful Lewis bases.
It is possible to farm it in 100% seawater and directly connect its cultivation system to an aquaculture system for a wide range of fish species. [2] Common ice plant is known to accumulate high levels of heavy metals when grown in soil. This new system enables the farming of safe-to-eat organic ice plant by removing it from this environment.

The Game of the Day wants you to go under the sea one more time. In Fish Tycoon: The object of this fishy tycoon game is to discover the 7 MAGIC FISH. You start with a small selection of fish ...
The hydride adds to an electrophilic center, typically unsaturated carbon. Hydrides such as sodium hydride and potassium hydride are used as strong bases in organic synthesis. The hydride reacts with the weak Bronsted acid releasing H 2. Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from ...
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
The work presented experiments on the co-cultivation of tilapia and tomatoes, showcasing the practicality of a recirculating system that supports both fish and plant production. [20] This research is among the efforts by a global community of researchers to develop modern aquaponics systems. Balarin and Haller conducted studies on the thermal ...
Plants respond differently depending on the form of nitrogen, e.g., ammonium has a positive charge, and thus, the plant expels one proton (H +) for every NH + 4 taken up resulting in a reduction in rhizosphere pH. When supplied with NO − 3, the opposite can occur where the plant releases bicarbonate (HCO − 3) which increases rhizosphere pH ...
