Exploring Beyond the Helmholtz Coils for Uniform Magnetic Field Generation with Topology Optimization

Yves Perriard, Adrien Jean-Michel Thabuis, Xiaotao Ren, Minh Trung Duöng

Uniform magnetic fields are desired in a wide range of applications. The most known device achieving such a purpose is the pair of Helmholtz coils. It consists of two identical circular coils, with their main axis aligned and placed at a distance equal to ...

The Role of Organic Promoters in the Electroreduction of Carbon Dioxide

Paul Joseph Dyson, Dmitry Vasilyev

The electrochemical reduction of carbon dioxide (CO2RR) currently attracts considerable attention as a way to make fuels and value-added products from CO2 using renewable energy. Much effort has been devoted to developing efficient electrode materials for ...

Crossover of liquid products from electrochemical CO2 reduction through gas diffusion electrode and anion exchange membrane

Andreas Züttel, Wen Luo, Jie Zhang

We reveal that a significant amount (>30%) of the liquid products from electrochemical CO2 reduction (CO2RR) in a flow reactor can cross the gas diffusion electrode (GDE) and anion exchange membrane (AEM). Crossover of volatile products through the GDE occ ...

Synergistic Cu/CeO2 carbon nanofiber catalysts for efficient CO2 electroreduction

Wen Luo, Jie Zhang

The electrochemical reduction of carbon dioxide (CO2RR) has attracted enormous interest because of the energy crisis and climate change; however, more efficient catalysts are required for practical applications. Herein, we present electrospinning as a faci ...

Multi-Channel AlGaN/GaN In-Plane-Gate Field-Effect Transistors

Elison de Nazareth Matioli, Jun Ma, Catherine Erine, Giovanni Santoruvo

In this letter, we present a multi-channel in-plane-gate field effect transistor (MC-IPGFET). In the proposed device, multiple vertically stacked two-dimensional electron gases (2DEGs) are simultaneously controlled by lateral in-plane gates formed with the ...

Pulses in Upward Negative Lightning at the Säntis Tower in Northeastern Switzerland

Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello, Lixia He

Upward lightning happens predominantly from tall objects. The channel-base currents associated with upward negative lightning initiated from towers exhibit pulses that can be classified, based on their waveform features and on the concurrence with other pr ...

Observation of tau(-) -> pi(-)nu(tau)e(+)e(-) and search for tau(-) -> pi(-)nu(tau)mu(+)mu(-)

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Ke Huang, Donghyun Kim, Lei Li

We present the first measurements of branching fractions of rare tau-lepton decays, tau(-) -> pi(-)nu(tau)l(+)l(-) (l = e or mu), using a data sample corresponding to 562 fb(-1) collected at a center-of-mass energy of 10.58 GeV with the Belle detector at t ...

Multirotor UAV-based platform for the measurement of atmospheric turbulence: validation and signature detection of tip vortices of wind turbine blades.

Fernando Porté Agel, Lionel Wilhelm, Fernando Carbajo Fuertes

The present study describes the development of a technique for the measurement of atmospheric turbulence and temperature at a point in space based on the integration of a fast-response multi-hole pressure probe and a thermocouple with an inertial measureme ...
