Abstract: Techniques for calibrating a high fidelity (HF) model of molten droplet coalescence are disclosed. An example method includes selecting initial HF parameter values for the HF model. The method also includes iteratively refining the HF parameter values until the HF model converges with experimental data. At each iteration, the HF parameter values are applied to the HF model and a plurality of simulations are run using the HF model to generate the simulated numerical data. For each simulation, a Reduced Order Model (ROM) is fitted to the simulated numerical data to generate ROM parameter values for ROM parameters of the ROM. Correlations between the ROM parameters and the HF parameters are identified to narrow the search space to be searched in a next iteration.

Abstract: A computational method for characterizing a biopolymer property of a biopolymer. The computational method includes receiving a dimensional representation of a molecule concentration over time within a fluid flow of a fluid medium flowing through a fluid channel including the biopolymer; predicting a fluid flow velocity and/or a fluid flow pressure of the fluid medium in response to the dimensional representation of the molecule concentration over time within the fluid medium using a machine learning model; and characterizing the biopolymer property of the biopolymer in response to the fluid flow velocity and/or the fluid flow pressure.

Abstract: A composition of matter, has a solid foam, at least one ionic conductor in the foam, and an electronic conductor in the foam. A battery has an anode, comprising a metal electrode and a solid foam, a cathode, and a solid electrolyte between the anode and the cathode, the solid electrolyte in contact with the solid foam. A solid foam has an electronic conductor, a hard ionic conductor, and a soft ionic conductor.

Abstract: A method of fabricating a nanoscale topography system for inducing unfolding of a DNA molecule for sequencing includes providing a substrate and creating trench walls on the substrate which define a trench therebetween. The method further includes depositing a layer of a block copolymer (BCP) in the trench and forming cylindrical domains by self-assembly of the BCP between the trench walls, removing a first portion of the cylindrical domains to create a vacant region in the trench, and depositing a subsequent layer of the BCP in the vacant region and forming spherical domains by self-assembly of the BCP between the trench walls adjacent a second portion of the cylindrical domains. The spherical domains form staggered post structures for unfolding the DNA molecule and the cylindrical domains form parallel channel structures for entry of the DNA molecule for sequencing.

Abstract: A solid composite battery separator is used to enable the use of a metal negative electrode in a battery. The metal negative electrode may be lithium metal, sodium metal, magnesium metal, zinc metal, or alloys of the metals listed. The composite separator includes a matrix and reinforcing material introduced into the matrix to increase fracture toughness of the composite separator. The composite separator comprises, either wholly or in part, a layer of reinforced polymer, ceramic or glassy lithium ion conductor. The matrix of the composite separator can include polyethylene oxide, LLZO, LiPON, or LATP. The reinforcing material of the composite separator can include fibers, particles, plates, or layers. The reinforcing material can include silicate glass, carbon nanotubes, silver nanowires, silicon carbide particles, and metallic particles.
