According to one embodiment, a method includes forming a structure by printing an ink, the ink including a glass-forming material, and heat treating the formed structure for converting the glass-forming material to glass. According to another embodiment, an ink composition includes a glass-forming material and a solvent.

Engineered feedstocks for additive manufacture of glass

The present disclosure relates to a method for forming a transport mechanism for transporting at least one of a gas or a liquid. The method may comprise using a 3D printing operation to form the mechanism with an inlet and an outlet, and controlling the 3D printing operation to create the mechanism as an engineered surface structure formed in a layer-by-layer process. The method may further comprise controlling the 3D printing operation such that the engineered surface structure includes a plurality of cells propagating periodically in three dimensions, with non-intersecting, non-flat, continuously curving wall portions which form two non-intersecting domains, and where the wall portions have openings forming a plurality of flow paths extending in three orthogonal dimensions throughout from the inlet to the outlet, and such that the engineered surface structure has wall portions having a mean curvature other than zero.

Systems and methods for periodic nodal surface based reactors, distributors, contractors and heat exchangers

The present disclosure relates to a transport mechanism apparatus for transporting at least one of a gas or a fluid. The transport mechanism may have an inlet, an outlet and an engineered cellular structure forming a periodic nodal surface, which may include a triply periodic minimal surface (TPMS) structure. The structure is formed in a layer-by-layer three dimensional (3D) printing operation to include cells propagating in three dimensions, where the cells include non-intersecting, continuously curving wall portions having openings, and where the opening in the cells form a plurality of flow paths throughout the transport mechanism from the inlet to the outlet, and where portions of the cells form the inlet and the outlet.

The silicone-based ink for additive manufacturing includes a siloxane macromer, and a porogen mixture comprising a water-soluble porogen and a surfactant. The product of additive manufacturing with a silicone-based ink includes a three-dimensional printed structure including a plurality of continuous filaments arranged in a predefined pattern and a plurality of inter-filament pores defined by the predefined pattern of the continuous filaments. In addition, each continuous filament of the three-dimensional printed structure includes a silicone matrix having an open cell structure with a plurality of intra-filament pores, and the intra-filament pores form continuous channels through the silicone matrix.

A composite material for gas capture including COcapture and capture of other gases. The composite material includes solid or liquid reactive material, filler material, and a gas-permeable polymer coating such that the reactive material forms micron-scale domains in the filler material.

Composite 3D-printed reactors for gas absorption, purification, and reaction

A composite material for gas capture, notably COcapture and storage. The composite material includes a mixture of a solid or liquid reactive filler and a gas-permeable polymer such that the reactive filler forms micron-scale domains in the polymer matrix.

A system is provided to automatically monitor and control the operation of a microfluidic device using machine learning technology. The system receives images of a channel of a microfluidic device collected by a camera during operation of the microfluidic device. Upon receiving an image, the system applies a classifier to the image to classify the operation of the microfluidic device as normal, in which no adjustment to the operation is needed, or as abnormal, in which an adjustment to the operation is needed. When an image is classified as normal, the system may make no adjustment to the microfluidic device. If, however, an image is classified as abnormal, the system may output an indication that the operation is abnormal, output an indication of a needed adjustment, or control the microfluidic device to make the needed adjustment.
