Methods for forming alane are described. The method drives the alane producing chemical reaction by a mechanical energy source such as a ball mill and includes stabilization of the product with solvent. At least one of the reactants is insoluble in the solvent. Thus, the product is both stabilized and phase-separated from the reactant(s) immediately upon formation. The method can be used to form -alane, for instance for use in hydrogen storage.

The present invention relates to a system for storing dihydrogen, characterized in that it comprises a suspension of elements, in the form of hydride particles having a mean diameter of between 1 nm and 800 nm, suspended in an alloy of at least two alkali metals, chosen from Na (sodium), K (potassium) and Li (lithium). The invention also relates to a method for storing dihydrogen in a system as described above, a method for producing dihydrogen from such a system and also a device for implementing the latter method.

The present invention provides novel two-dimensional van der Waals materials and stacks of those materials. Also provided are methods of making and using such materials.

Disclosed herein are systems and methods for heating alane etherate compositions for producing microcrystalline alpha alane. An exemplary heating method comprises introducing a preheated solvent into the alane etherate composition and rapidly stirring to effectuate rapid heating of the composition without the need to heat the reactor walls. In this way, the alane etherate composition can be heated while also reducing the risk of decomposition. In further embodiments, a two-stage reactor can be employed for producing alpha alane, wherein the heating occurs in the second stage.

A method for producing alane is provided. The method comprises forming a solution comprising an alane adduct and a Lewis acid. The alane adduct comprises alane and a coordinating ligand. The method further comprises exposing the solution to a laser or high-power light at a at least one wavelength selected to cause dissociation of a bond between the alane and the coordinating ligand, resulting in crystallization of the alane and binding of the coordinating ligand to the Lewis acid after dissociation and separating the crystallized alane from the coordinating ligand and Lewis acid.
