research worker have discovered a " shape - recover liquidity " that appears to defy the law ofthermodynamics . The liquid state , which is made up of oil color , piss and magnetic particle , consistently separates into a form resembling a Greek urn .
This discovery began whenAnthony Raykh , a polymer science and engineering alumna student at the University of Massachusetts Amherst , was studying a mixture of crude , water and atomic number 28 atom in a ampul . He shook the ampule to create an emulsion — or a portmanteau word of liquids that do n’t mix . But instead of split up into a clear top and bottom , the mixture formed the shape of a Greek urn . Even after shaking the ampoule over and over , it keep render to this shape .
" That ’s really odd , " study co - authorThomas Russell , a prof of polymer science and engineering at University of Massachusetts Amherst , told Live Science . It ’s unusual , he explain , because typically when a commixture of liquids that do n’t intermix takings to sense of balance before emulsion , they want to minimize the interfacial area , or the limit between the two liquids . This inclination to minimize the interfacial area is govern by the law of nature of thermodynamics , which report how temperature , heat , employment and energy are related in physical system .
In typical photographic emulsion of fossil oil and water , the liquids form ball-shaped droplets , which have minimal Earth’s surface arena . In comparison , the Hellenic urn build has a higher surface arena . This eminent Earth’s surface area , which seems to negate the police force of nature , puzzled the researcher .
After investigating this odd conduct , they found that fundamental interaction between the nickel atom " sort of guide over " to create what come out to be a violation of the Torah of thermodynamics , Russell said . The particle created magnetic dipole , a phenomenon where their magnetised poles pull in each other , create a field of " chain " on the liquid ’s surface . This interaction interferes with how the photographic emulsion assort .

While Russell say researchers have antecedently analyze the sequestration of particles in oil color - water mixing — as Raykh had been doing — nobody else had conduct the same experimentation . So , no other researchers had observe or report the high interfacial energy seen with the Grecian urn form .
While at first glance this mixture seems to defy the laws of thermodynamics , Russell clarified that it ’s just a strange character of them . The scientists realized that the particle ' magnetic intervention played a role , as its influence created a higher interfacial energy , which resulted in the higher surface orbit - anatomy . And in oecumenical , the laws of thermodynamics apply to system overall , not to the fundamental interaction between private particles , Russell said .
The researchers published their findings on April 4 in the journalNature Physics .
