Some of the most revealing signals about human health are carried in fluids that are almost impossible to measure. Tears, cerebrospinal fluid, and prostate fluid appear only in tiny volumes, yet their ...

Space probes, gas pipelines, and other applications require an ongoing source of thermoelectric power without direct human maintenance, but current technologies for the corresponding energy conversion ...

Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...
