摘要： A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.

摘要： A system for heat transfer along with the method of preparation of the same is described. System includes a first surface, a second surface, and an interface material. The interface material is disposed between the first and second surfaces such that it is solid at an assembling temperature and liquid at an operating temperature. The first surface of the system is configured to adhere to the solid and liquid thermal interface material, and the second surface is configured to adhere to the liquid thermal interface material and be detachable from the solid interface material. The method of preparation of the system includes disposing the first surface, an interface material, and a second surface, heating the interface material to above its melting point and then cooling to a temperature below melting point to detach and remove the second surface from the interface material.
