This study presents a novel microfluidic chip integrated with biosensors and capillary microfluidics, specifically designed for target screening and precise fluid control. The capillary pumps facilitate spontaneous fluid delivery to the sensors, eliminating the necessity for external ... En savoir plus

Photoacoustic spectroscopy (PAS) enables highly sensitive gas detection without optical detectors by directly measuring the sound generated from light absorption. However, the performance of PAS systems strongly depends on the photoacoustic cell’s acoustic design. In this work, we ... En savoir plus

Guided wave technology offers a promising approach for non-destructive testing (NDT), particularly in the detection of corrosion in critical structures such as pipelines. This study focuses on utilizing COMSOL Multiphysics to simulate guided wave propagation for optimizing corrosion ... En savoir plus

Large underground mines (LUMs), which constitute over 60% of metal and nonmetal mining operations in the United States, are critical to national infrastructure and materials supply (Bhattacharyya et al., 2023; Gendrue et al., 2021). These mines are characterized by vast entries exceeding ... En savoir plus

The aim of this work was to simulate the electro-thermal behavior of a micro-hotplate used as a gas sensor, in order to compare the obtained results with a real structure. The structure has been designed in 3D and a stationary and a temporal study has been realized. En savoir plus

Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... En savoir plus

Curing concrete is best achieved by keeping it nearly saturated at an appropriate temperature until all the cement has fully reacted. However, when installing flooring materials that require low relative humidity (RH) in the concrete, the slab needs to dry as quickly as possible. ... En savoir plus

Electrodialysis (ED) is a unit operation for the separation of electrolytes with numerous applications in the chemical, food and biotechnological fields. Its modeling requires estimating several parameters and performing many batch desalination experiments (Fidaleo and Moresi, 2005). ... En savoir plus

Introduction Most current thermoregulation models represent the body in significantly simplified forms, e.g., cylinders or spheres. These simple geometries do not fully represent the complexity of bones, organs, etc. contained in the human body. Modern medical technologies allow for more ... En savoir plus

Rapid advancements in composites have positioned epoxy resins as a critical material in high-pressure applications such as water transport systems, oil and gas transport, and marine and aerospace applications. Epoxies are preferred over other materials due to their enhanced mechanical ... En savoir plus
