Concentrating particles in a turbulent gas flow may include receiving, in a receptacle, a turbulent gas flow that includes particles. The concentration of particles in a gas flow exiting the receptacle at a first port is increased as compared with a concentration of the particles in the gas flow received by the receptacle. The increased concentration of particles is accomplished by removing a portion of the gas flow by using a second port, and fluidly communicating the gas flow through a tube in the receptacle. The tube has a smaller diameter at the end of the tube at which the gas flow exits the tube than diameter at the end of the tube at which the gas flow is received.

A particle-harvesting material includes a flexible, reusable, and thermally conductive material including a rough surface having dimples of a size within a first range of sizes, a microstructure including interstices of a second range of sizes, the second range of sizes including sizes smaller than the first range of sizes, and an etched portion on the rough surface configured to attract particles upon contact between the particles and the etched portion.
