WebbThermal imaging, as the term is commonly used, refers to an infrared imaging system designed specifically for the portion of the infrared range which is emitted by object at or just above room temperature. This is typically in the neighborhood of 10 microns. WebbNanomembranes are the most widespread building block of life, as they encompass cell and organelle walls. Their synthetic counterparts can be described as freestanding or free-floating structures thinner than 100 nm, down to monatomic/monomolecular thickness and with giant lateral aspect ratios. The structural confinement to quasi-2D sheets causes a …
