Defying gravity with the Brazil nut effect

Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

Migrating ions through the perovskite layer in two dimensions

Electrostatic doping has been widely used in low-dimensional materials, including carbon nanotube (CNT) and two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs). Unlike conventional ...

Nanobiosensor developed for detecting SARS-CoV-2

Infection and immunity status of the population are considered key parameters for handling pandemics. For this purpose, detecting antigens and antibodies is of great importance. The devices currently used for this purpose—what ...

A new chapter in antiferromagnetic spintronics is unfolding

Electronics play a pivotal role in today's information society. Yet only the electron charge in electronic devices is at play, making energy dissipation an increasingly pressing issue that thwarts further development. Spintronics, ...
