11518864 · 2022-12-06 · ·

There is described a microwave pyrolysis process for the depolymerization of plastic for the production of monomers, waxes and heavy oils including the steps of: a) steam purge of the plastic from about 0.5% to about 50% w/w of a catalyst, in a media; b) pyrolysis of the plastic and the catalyst in the media with a microwave (MW) for a time sufficient to allow generation of heat providing a thermal treatment between 300° C. and 650° C. through absorption of microwaves by the catalyst and the media. The catalyst includes a compound having a high dielectric loss at the frequency of the MW to absorb microwaves, transfer heat to the plastic and initiate a pyrolysis reaction.

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.
