Russian and French researchers say an experimental approach for demonstrating the existence of an axionic behavior in specific materials may not have found it as previously reported. In Applied Physics Letters, the multinational team was unable to detect the expected increased magnetoconductivity in the charge density wave of a compound made up of tantalum, selenium, and iodine, called (TaSe4)2I. The findings come three years after published research seemed to provide sufficient evidence for an axionic behavior using a similar approach.
In Physics of Fluids, researchers use dissipative particle dynamics simulations to examine the translational diffusion of Janus nanoparticles at the interface between two immiscible fluids. The simulations shed light on the dynamic behavior of the nanoparticles at a water-oil interface, and the work reveals a strong influence of their shape on their orientation at the interface as well as on their mobility. In theory, these findings imply the geometrical characteristics of Janus particles can be modified without their surface chemistries becoming altered to produce either stable or unstable emulsions.
Quarks and gluons are found deep inside protons and neutrons but also combine in less common configurations to make other subatomic particles.
