Abstract: A lab-on-chip platform is provided and includes a substrate. The substrate includes a microfluidic path. The microfluidic path has multiple inputs and an output and an analysis area downstream from a mixing area. The lab-on-chip platform further includes a cover disposed on the substrate to partially enclose the microfluidic path, a mineral layer deposited in at least the mixing area and obstructions. The mineral layer is configured to at least partially chemically react with fluid within the microfluidic path to form at least first particles and second particles, which are substantially smaller than the first particles. The obstructions are formed or disposed in the analysis area and configured to capture the first particles in the analysis area and to allow the second particles and unreacted fluid to pass out of the analysis area.

Abstract: A rapid test device includes a micropad chip configured for a multi-parameter chemical testing of an input sample. A plurality of paper layers of the micropad chip are in fluid communication, including a sample absorption element, a filtering element configured to filter the input sample, and a sample distribution element configured to distribute the input sample received from the filtering element to a remainder of the plurality of paper layers. One or more reacting elements associated with the multi-parameter chemical testing of the input sample have one or more colorimetric reagents in fluid communication with the sample distribution element. A colorimetric result displaying element in fluid communication with the one or more reacting elements is configured to display a colorimetric result of the testing of the input sample with the at least one reacting element for a respective chemical test of the multi-parameter chemical testing.

Abstract: Devices and methods for controlling collection of liquid sample are described. In an example, a microfluidic device can include an analytical device and an actuator. The actuator can be connected to the analytical device. The actuator can be operable to absorb fluid. The actuator can guide the absorbed fluid to an input layer of the analytical device. The actuator can deform in response to an occurrence of an absorption condition. A degree of deformation of the actuator indicates a volume of fluid collected by the analytical device.

Abstract: A multiplexed lateral flow assay device includes an impermeable internal reservoir having an opening to receive a sample deposition. A fluid distributor pad is arranged in fluid communication with a lower surface of the internal reservoir and divides a portion of the sample deposition substantially equally among a plurality of flow paths. Lateral flow assays having a plurality of flow lines are aligned with flow paths of the distributor pad. An impermeable paper top cover has a first window arranged over the opening of the internal reservoir, and at least a second window arranged over the test results of the lateral flow assays. A housing element houses the reservoir, the distributor pad and lateral flow assays. The housing element includes an impermeable bottom cover and a spacer element arranged between the top and bottom covers and, provides a gap between the lateral flow assays and the impermeable paper top cover.

Abstract: A method can include determining by photogrammetry, a first volume of a food-product unit and a second volume of a food-product subunit. The food-product subunit can be a separated portion of the food-product unit. The method can further include generating a code for the food-product subunit. The code can include a first identifier for the food-product unit and a second identifier for the food-product subunit. The first identifier can be based, at least in part, on the first volume. The second identifier can be based, at least in part, on the second volume. The method can further include assigning the code to the food-product subunit.

Abstract: Ranking materials for post combustion carbon capture by characterizing sorbent materials with a molecular model workflow that generates microscopic figures of merit for materials by microscopic properties; and evaluating the materials from the molecular model workflow with a process model workflow that generates macroscopic figures of merit for process steps of a carbon recovery process. The materials for applicability as a sorbent material are ranked using a combined microscopic performance and macroscopic process feasibility generator that ranks the materials according to the microscopic figures of merit for materials and the macroscopic figures of merit for the process steps.

Abstract: In response to receiving an input of a user criteria for operating a system, one or more predictive models are selected in dependence on the user criteria. The predictive models predict behavior of the system and are stored in the memory with one or more system performance models that control operation of the system. The selected performance model(s) is implemented to select a subset of sensors that monitor physical conditions of the system and/or environmental parameters thereof, and is also used to select one or more of the system performance models that conform to the user criteria. One or more actuators associated with the system are controlled according to inputs received from the selected subset of sensors and the selected performance model(s). The same concepts are valid for other areas rather than maintenance, like optimization in the area of the internet of things, dynamic system reconfiguration, preventive healthcare.
