Double with Metasurface: Double layer devices can control many forms of polarization
Scanning electron microscope images of titanium dioxide metatras. Credit: Capasso Group / Harvard Seas Almost a decade ago, Harvard engineers introduced Lulatai’s thin flat device, the world’s first visible spectral metasurface, patterned with nanoscale structures that allow precise control of light behavior. Today, a powerful alternative to traditional bulky optical components, Metasurfaces enables compact, lightweight, multifunctional applications ranging from imaging…

The double magical core of the Lead-208 goes against expectations with its amazing shape properties
Experimental setup to study Double Magic Lead-208. Credit: Argonne National Laboratory. anl.gov/article/welcome-back-gretina. In a surprising event, an international team of scientists discovered that the heaviest known “double magic” nucleus, Lead-208 (208pb), exhibits unexpected geometric properties that current nuclear models cannot be accurately predicted. Double magic refers to a nucleus with a full shell of both protons (82) and neutrons (126).…

Scientists develop new model of electric double layer
Credit: CC0 Public Domain The new model takes into account a wide range of ion-electrode interactions and predicts the charge storage capacity of the device. The model’s theoretical predictions are consistent with the experimental results. Data on electric double layer (EDL) behavior can help develop more efficient supercapacitors for portable electronics and electric vehicles. The study was published in ChemPhysChem.…
