Deformation of hydrogel used to measure the negative pressure of water

Water has the potential to withstand a massive stretching force or tension due to its internal cohesive force. The hydrostatic pressure of the water would display as absolute negative. The comprehension of such a unique thermodynamic non-equilibrium state in the phase diagram of water...

Nanomagnet arrays can order themselves by increasing entropy, without violating thermodynamics laws

Extremely small arrays of magnets with strange and unusual properties can order themselves by increasing entropy. The tendency of physical systems to disorder which is a behaviour that appears to contradict standard thermodynamics, but doesn't. The system examined in this work is known as tetris...
