Figure 1: Graphene-clad silicon photonic crystal nanostructures. Figure 4: Parametric four-wave mixing in graphene-clad silicon nanocavities. We have demonstrated, for the first time, a hybrid ...

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

As many believe, the Big Bang started our universe. But not everyone is aware that the early world is nothing like what we can see these days. There's no stars, planets, galaxies or nebulas. For a bit ...

Jean-Michel Ménard, Associate Professor of Physics at the University of Ottawa and a team of researchers have paved the way for developing devices capable of upconverting electromagnetic signals to ...

ABSTRACT The North Atlantic Oscillation (NAO) response to the northeast Pacific climate variability is examined using the ERA-40 dataset. The main objective is to validate a mechanism involving ...

Scientists have recently found that the temperatures in Saturn's equatorial atmosphere oscillate with a period of about 15 Earth years. The temperature swing's signal was detected by analyzing ...
