Controlling ice formation

(Phys.org)—Researchers have demonstrated that ice crystals will grow along straight lines in a controlled way on microgrooved surfaces. Compared to the random formation of ice crystals on smooth surfaces, the ice on the ...

Unusual fluid behavior observed in microgravity

(Phys.org)—Normally when a liquid is heated above its boiling point, it evaporates, turning into a vapor. But when scientists recently performed an experiment on the International Space Station (ISS), they observed that ...

How small can superconductors be?

For the first time, physicists have experimentally validated a 1959 conjecture that places limits on how small superconductors can be. Understanding superconductivity (or the lack thereof) on the nanoscale is expected to ...

Quantum shortcuts cannot bypass the laws of thermodynamics

(Phys.org)—Over the past several years, physicists have developed quantum shortcuts that speed up the operation of quantum systems. Surprisingly, some of these shortcuts theoretically appear to enable systems to operate ...

Nanoscale logic machines go beyond binary computing

(Phys.org)—Scientists have built tiny logic machines out of single atoms that operate completely differently than conventional logic devices do. Instead of relying on the binary switching paradigm like that used by transistors ...

Scientists solve puzzle of turning graphite into diamond

(Phys.org)—Researchers have finally answered a question that has eluded scientists for years: when exposed to moderately high pressures, why does graphite turn into hexagonal diamond (also called lonsdaleite) and not the ...

Friction in the vacuum?

(Phys.org)—When three physicists first discovered through their calculations that a decaying atom moving through the vacuum experiences a friction-like force, they were highly suspicious. The results seemed to go against ...
