To protect the mineral, the researchers first apply a thin wash of a chemical called aminoethylaminopropylsilane, more mercifully known as aeaps, that seeps into
microscopic cracks in the stone and binds to calcium carbonate.
The simplest «experiment» is to watch as a container full of liquid helium suddenly springs a leak as it is cooled below the lambda point and the frictionless superfluid fraction begins to pour
through microscopic cracks that the normal liquid fraction can not enter.
Over-scrubbing, exfoliating too harshly or too often, and even washing your face with harsh formulas can
create microscopic cracks in your outer skin, leading to irritation and loss in hydration, according to Dr. Zeichner.
Radon can enter a home or workplace through the hot water tank, sink, shower, and
microscopic cracks in a building's foundation.
In science and industry, we attempt to find the limits; what and when stress factors push something to breaking point, where
the microscopic cracks start to develop, and at what point breaking become inevitable.
