Bifunctional WO3 Photoelectrodes Decorated by Inkjet Printing for Solar Supercapacitors
Advanced Sustainable Systems, EarlyView.WO3 bifunctional photoelectrodes, produced by screen printing and then superficially decorated by inkjet printing, are successfully applied to prepare solar supercapacitors. Under illumination, the areal capacitance is enhanced thanks to the positive contribution of the photogenerated charges and the higher exposed area; its value becomes even more ...

Prandtl number effect on near wall temperature profile in high-Reynolds number channel flows
Nihon Kikai Gakkai ronbunshu, 2014 Prandtl number (Pr) effects on characteristics of the thermal boundary layer were investigated by means of Direct Numerical Simulations (DNS) in high-Reynolds number turbulent channel flows. The molecular Pr conditions were changed from 0.71 to 25.0, and

Etherification of Bio‐Based Furanic Compounds via Continuous Flow
Advanced Sustainable Systems, EarlyView.A comprehensive investigation on the etherification of bio‐based furanic compounds using a continuous flow apparatus. Reaction conditions are optimized for the synthesis of BEMF and then used to obtain a library of BAMFs. Additionally, the self‐etherification of HMF to produce OBMF is explored both in heterogeneous and by employing the homogeneous ...

Advanced Theory and Simulations, EarlyView.FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

Advanced Theory and Simulations, EarlyView.Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude
