Ancient effect harnessed to produce electricity from waste heat

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind ...

Tiny generators turn waste heat into power

The second law of thermodynamics is a big hit with the beret-wearing college crowd because of its implicit existential crunch. The tendency of a closed systems to become increasingly disordered if no energy is added or removed ...

Fractons as information storage: Not yet tangible, but close

Excitations in solids can also be represented mathematically as quasiparticles; for example, lattice vibrations that increase with temperature can be well described as phonons. Mathematically, also quasiparticles can be described ...

Imaging magnetic instabilities using laser accelerated protons

The magnetic structures resulting from a plasma instability predicted by the physicist Erich Weibel about 50 years ago have been evidenced at surprisingly large scales in a laser-driven plasma in the prestigious journal Nature ...

Isolating water's impact on vibrations within DNA

In a biological system, the ratio of water-to-non-water molecules, known as the hydration level, influences both the arrangement of biomolecules and the strength of the electric interactions that occur between biomolecules, ...

Pulsating dust cloud dynamics modeled

The birth of stars is an event that eludes intuitive understanding. It is the collapse of dense molecular clouds under their own weight that offers the best sites of star formation. Now, Pralay Kumar Karmakar from the Department ...
