Therefore, it was utilized to fabricate a functional paper chip to perform the visualized detection of formaldehyde gas. The result displayed a sensitive response to formaldehyde gas in the concentration range of 0.02 ~ 0.08 mg/m 3. Besides, the whole colorimetric assay merely takes 150 s, suggesting a favorable application prospect in the on ...

7.1.1 Leaks and leak detection. In non-destructive testing, a leak is defined as a hole, a porous area, a permeable area for gases or a different structure in the wall of a test specimen through which a gas can escape from one side of the wall to the other due to a difference in pressure or concentration .Expressed in simpler terms, leaks are small holes through which gases or liquids flow ...

2 days agoCaption: A test version of the new detection system is seen in the lab, where it underwent tests inside glass tubes to allow its operation to be observed. The propulsion module, at right, is fitted with electric wheels and motors to move the device through the pipe. The leak sensor, at left, is a drum-shaped membrane that can sense changes in pressure caused by the presence of a leak.
