Abstract: Methods and systems for providing reward based verified recommendations. A method disclosed herein includes broadcasting a recommendation request to a plurality of registered users, on receiving the recommendation request from a customer. The method further includes receiving and verifying an input from at least user of the plurality of users in response to the broadcasted recommendation request using a blockchain. The received input relates to the recommendation request and the input includes at least one of at least one service provider and at least one service provided by the at least one service provider. The method also includes issuing reward points (RPs) to the at least one user who has provided the input and the service provider who is included in the input on verifying the input. The method further includes providing at least one recommendation to the requested customer using the verified input and maintained previous recommendations.

Abstract: An evaluation system that may include an imager; and a processing circuit. The imager may be configured to obtain an electron image of a hole that is formed by an etch process, the hole exposes at least one layer of a one or more sets of layers, each set of layers comprises layers that differ from each other by their electron yield and belong to an intermediate product. The processing circuit may be configured to evaluate, based on the electron image, whether the hole ended at a target layer of the intermediate product. The intermediate product is manufactured by one or more manufacturing stages of a manufacturing process of a three dimensional NAND memory unit. The hole may exhibit a high aspect ratio, and has a width of a nanometric scale.

Abstract: Exemplary embodiments in desalination by direct contact membrane distillation present a cylindrical cross-flow module containing high-flux composite hydrophobic hollow fiber membranes. The present embodiments are directed to a model that has been developed to describe the observed water production rates of such devices in multiple brine feed introduction configurations. The model describes the observed water vapor production rates for different feed brine temperatures at various feed brine flow rates. The model flux predictions have been explored over a range of hollow fiber lengths to compare the present results with those obtained earlier from rectangular modules which had significantly shorter hollow fibers.

Abstract: A method for determining overlay between layers of a multilayer structure may include obtaining a given image representing the multilayer structure, obtaining expected images for layers of the multilayer structure, providing a combined expected image of the multilayer structure as a combination of the expected images of said layers, performing registration of the given image against the combined expected image, and providing segmentation of the given image, thereby producing a segmented image, and maps of the layers of said multilayered structure. The method may further include determining overlay between any two selected layers of the multilayer structure by processing the maps of the two selected layers together with the expected images of said two selected layers.

Abstract: Using porous hollow fiber membranes, systems/methods for continuously synthesizing polymer-coated particles by anti-solvent crystallization are provided. The disclosed systems/methods provide for synthesis of polymer-coated drug particles/crystals from solutions of the polymer and the drug particles in suspension by exposing the solution to an anti-solvent through a porous hollow fiber device. A feed solution of a coating polymer with suspended drug particles can be exposed to an anti-solvent through hollow fiber pores, thereby causing the polymer to precipitate on and coat the drug particles. In addition, a feed solution of a coating polymer with drug in solution can be exposed to an anti-solvent through hollow fiber pores, thereby causing the drug to crystallize from the solution and the polymer to precipitate/coat the drug. Results indicate that a uniformly coated, free-flowing product may be developed in this advantageous porous hollow fiber anti-solvent crystallization method.

Abstract: The present disclosure relates to the field of polymer coating. The present disclosure provides improved systems and methods for continuous polymer coating of particles (e.g., nanoparticles). The present disclosure provides for a solid hollow fiber cooling crystallization (SHFCC) technique to continuously coat the nanoparticles with polymer. In certain embodiments, the present disclosure embraces continuous coating of particles from about 1 nm to about 10 microns. A polymer solution containing a suspension of submicron particles flows in the lumen of a solid polymeric hollow fiber, and controlled cooling of the polymer solution allows for polymer nucleation on the surface of the particles, and the precipitated polymer forms a thin film around the particles (the thickness of which can be varied depending on the operating conditions). The systems, methods and assemblies of the present disclosure are easily adaptable for coating nano-sized drug particles as well.
