Systems for hydrocarbon pyrolysis are provided, which may comprise a reactor configured to contain a liquid metal; a heater operably coupled to the reactor to form a heating zone; a cooler operably coupled to the reactor to form a cooling zone; a gas delivery assembly comprising an inlet and configured to deliver a feed gas comprising a hydrocarbon as a plurality of bubbles through the liquid metal; an outlet configured to deliver a product gas to a separation assembly, the product gas formed from pyrolysis of the hydrocarbon in the liquid metal, the product gas comprising Hand carbon; and the separation assembly configured to separate the carbon from other components of the product gas. The reactor is configured to entrain the carbon from pyrolysis of the hydrocarbon in the liquid metal into the product gas without accumulating the carbon in the interior chamber during pyrolysis.

Systems and methods for hydrocarbon pyrolysis

A micro-assembly system includes a reservoir that stores a supply of chiplets suspended in a suspension fluid. Each of the chiplets has a bottom major surface that defines a right side down orientation. The system includes a delivery surface or belt that delivers the chiplets from the reservoir to an assembly surface. The system includes a micro assembler that may arrange the first subset of the chiplets in a pattern on the assembly surface. The micro assembler moves the first subset of chiplets towards a subsequent assembly stage. The micro assembler has an array of field generators fixed relative to the assembly surface that move the first subset of the chiplets along the assembly surface in response to signals applied to each of the field generators.

A method of producing hydrogen may include: providing a catalyst-carbon gel; and flowing a hydrocarbon through a catalyst, wherein catalyst is a metal or mixture of metals that is non-wetting to solid carbon at 1 bar absolute and 10° C. above a melting point of the metal or mixture of metals.

Disclosed are methods and systems of controlling the placement of micro-objects on the surface of a micro-assembler. Control patterns may be used to cause electrodes of the micro-assembler to generate dielectrophoretic (DEP) and electrophoretic (EP) forces which may be used to manipulate, move, position, or orient one or more micro-objects on the surface of the micro-assembler. The control patterns may be part of a library of control patterns.

Control loop latency can be accounted for in predicting positions of micro-objects being moved by using a hybrid model that includes both at least one physics-based model and machine-learning models. The models are combined using gradient boosting, with a model created during at least one of the stages being fitted based on residuals calculated during a previous stage based on comparison to training data. The loss function for each stage is selected based on the model being created. The hybrid model is evaluated with data extrapolated and interpolated from the training data to prevent overfitting and ensure the hybrid model has sufficient predictive ability. By including both physics-based and machine-learning models, the hybrid model can account for both deterministic and stochastic components involved in the movement of the micro-objects, thus increasing the accuracy and throughput of the micro-assembly.

Apparatus for controlling the placement of micro-objects on a micro-assembler

Disclosed are methods and systems of controlling the placement of micro-objects on the surface of a micro-assembler. Control patterns may be used to cause phototransistors or electrodes of the micro-assembler to generate dielectrophoretic (DEP) and electrophoretic (EP) forces which may be used to manipulate, move, position, or orient one or more micro-objects on the surface of the micro-assembler.

Method of controlling placement of micro-objects

One embodiment provides a chemical reactor, which can comprise a substrate for facilitating chemical reactions occurring at triple-phase boundaries. One possible substrate may further comprise a set of dynamically controllable sites and/or pixels upon which control signals may affect a desired formation of gas bubbles over an active catalytic (or other desired) solid surface in a liquid flow&#x2014;wherein a chemical reaction in two or more phase boundaries may occur. In yet another embodiment, a control algorithm may send control signals to controllable sites/pixels to maximize the operation of the reactor according to a desired metric (e.g., product formation) that may input a set of sensor data to affect its control.
