Abstract: The present disclosure relates to photo-polymerizable resins, methods of photo-polymerizing and foaming resins, and foamed polymeric materials. Some disclosed resins comprise: a first monomer; a second monomer; a photo-activated polymerization catalyst; and a thermally activated foaming agent. Some disclosed methods of preparing photo-polymerized and foamed materials comprise photo-polymerizing a resin with a thermally activated foaming agent to obtain a photo-polymerized polymer material; and heating the photo-polymerized polymer material at a heating temperature to obtain the photo-polymerized and foamed polymer material, wherein the thermally activated foaming agent has a foaming onset temperature, and the heating temperature is greater than or equal to the foaming onset temperature. Also disclosed are photo-polymerized and foamed materials. Further disclosed are polymeric structures having a foam.

Abstract: A method for determining rock microscopic physical parameters and an apparatus may determine, based on the acquired macroscopic physical parameters and capillary pressure curve experimental data of a rock, a volume and a saturation of a nonwetting phase fluid injected into different pore throat distribution intervals, and calculate microscopic physical parameters of the rock, through which the properties of the rock, such as a pore structure, storage, seepage and the like can be depicted, thereby facilitating evaluation of hydrocarbon occurrences of a reservoir and formulation of a reasonable hydrocarbon field development strategy.

Abstract: The present disclosure relates to the use of occluding fluids, such as a high-density fluid (a “z-fluid”) or a low-density fluid (an “a-fluid”), to displace resin within a vat during 3D printing. Further, an a-fluid may act as a protective boundary for a 3D printing resin wherein the a-fluid sits on top of the printing resin. Another embodiment of the disclosure provides a process of assessing which regions of a computer-aided design (CAD) model take advantage of a buoying force supplied by the occluding fluid, such that fewer support structures are needed for printing a final CAD model compared to printing the CAD model without the occluding fluid.

Abstract: A soft neural interface connector apparatus includes a PCB having a two-dimensional array of solder balls, a transparent top board, a cushioning layer on one side of the transparent top board, and a soft neural interface including a flexible and/or stretchable microelectrode array (MEA) through which neural signals are obtained or delivered. The MEA includes a two-dimensional array of contact pads corresponding to the array of solder balls. The PCB, the transparent top board, the cushioning layer, and the MEA are stacked together such that the MEA is between the cushioning layer and the PCB, and the contact pads are aligned with and in electrical contact with associated solder balls. A magnetic connector system having at least one magnetic connector component on the transparent top board is magnetically connected with at least one magnetic connector component on the PCB to press the contact pads and associated solder balls together.
