Moreover, since the resulting interference pattern also depends on the waves' frequency, the same array can concentrate SAWs in different ways at different frequencies, working the liquidsample in different ways.
Not only does the new test enable the TB bacteria to be identified more quickly, it allows doctors to add various drugs to the liquid media in which the sample is grown to determine which would be of benefit in tackling the infection.
They've shown that a synthetically grown sample of herbertsmithite crystal (what you see above) behaves as a quantum spin liquid: a material where fractional quantum states produce a liquid-like flux in magnetic orientations, even if the material is solid.
