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.

Photon generating substrates for oligonucleotide synthesis

Photon generating substrates for light-directed oligonucleotide synthesis are disclosed. Light is generated within a solid-state stack that supports growing oligonucleotides. The light may be generated by microLEDs, a pass-through liquid crystal panel, or an LCoS system. Light passes through a transmissive layer on which growing oligonucleotides are attached. Patterning of the light is controlled by selective activation of the microLEDs or by selective control of the transparency of a liquid crystal layer. Photolabile blocking groups are selectively removed by exposure to patterned light emitted from the photon generating substrate.

20170244212 · 2017-08-24 · ·

Laser diode drivers include switching power supplies situated proximate one or more laser diode arrays so as to provide laser diode drive currents at frequencies of 200 kHz or more. The switching power supplies are generally buck/boost supplies that can provide well regulated outputs even when regulating remote power received from a power supply via a cables having inductances in the hundreds of nH. Multiple laser diode arrays can be driven with independently selectable powers. A drive current for a particular laser array can be controlled so as to reduce voltage drop at voltage control elements such as FETs, leading to increased efficiency, increased product life and decreased sense element failure.

MASK-LESS FABRICATION OF THIN FILM BATTERIES
20170214062 · 2017-07-27 ·

Thin film batteries (TFB) are fabricated by a process which eliminates and/or minimizes the use of shadow masks. A selective laser ablation process, where the laser patterning process removes a layer or stack of layers while leaving layer(s) below intact, is used to meet certain or all of the patterning requirements. For die patterning from the substrate side, where the laser beam passes through the substrate before reaching the deposited layers, a die patterning assistance layer, such as an amorphous silicon layer or a microcrystalline silicon layer, may be used to achieve thermal stress mismatch induced laser ablation, which greatly reduces the laser energy required to remove material.
