Transitions in the wintertime near-surface temperature inversion at Dome C, Antarctica

Etienne Gabriel Henri Vignon

In this work we study the dynamics of the surface-based temperature inversion over the Antarctic Plateau during the polar winter. Using 6 years of observations from the French-Italian Antarctic station Concordia at Dome C, we investigate sudden regime tran ...

Triboelectric effect to harness fluid flow energy

Danick Briand, Rubaiyet Iftekharul Haque

We are reporting energy scavenging from fluid flows inside tubular structures using triboelectric effects. Two separate designs of triboelectric generators are proposed. A tubular design that uses liquid-solid interaction mechanism for water, and freestand ...
