Finite element investigation of the Slotted-Hidden-Gap (SHG) connection for square HSS bracing members under cyclic loading
The Slotted-Hidden-Gap (SHG) connection is an improved version of the conventional welded tube-togusset connection between hollow braces and framing elements used in Concentrically Braced Frames (CBFs), offering an enhanced performance without the need for ...
2023Bidirectional Recoil Leaders in Upward Lightning Flashes Observed at the Säntis Tower
Marcos Rubinstein, Mohammad Azadifar, Antonio Sunjerga, Amirhossein Mostajabi
We report the observation of three negative upward flashes recorded by a high-speed camera at the Säntis Tower during the Summer of 2019. The camera was operating at 10,000 fps and an exposure time of 99 μs. Simultaneous measurements of the lightning curre ...

The transition in energy matrix, from fossil to renewable energy sources, will require the utilization of grid levelling alternatives to cope with the intermittent characteristic of renewable energy. Advanced electrochemical energy conversion and storage d ...
EPFL2019Print-Light-Synthesis of Ni and NiFe-nanoscale catalysts for oxygen evolution
Hubert Girault, Emad Oveisi, Mounir Driss Mensi, Andreas Stephan Lesch, Victor Costa Bassetto
By hyphenating inkjet printing and flash light irradiation, Ni- and NiFe-nano-electrocatalysts of diameters below 2.5 nm with ultralow loadings below 2 µg·cm–2 are synthesized. To achieve this, nanoliter ink volumes containing Ni and Fe chlorides as cataly ...
