Influencing Flow Patterns and Bed Morphology in Open Channels and Rivers by Means of an Air-Bubble Screen

Anton Schleiss, Koen Blanckaert, Violaine Dugué

The ability of a bubble screen to redistribute the flow field and bed morphology in shallow rivers and open channels has been investigated in laboratory experiments. Rising air bubbles generated by a pressurized porous tube situated on the bed induced seco ...

Redox couple for electrochemical and optoelectronic devices

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Jun Ho Yum, Aswani Yella, Hoi Nok Tsao

The present invention provides an improved redox couple for electrochemical and optoelectronic devices. The redox couple is based on a complex of a first row transition metal, said complex containing at least one mono-, bi-, or tridentate ligand comprising ...

Head losses in junction manholes for free surface flows in circular conduits

Michael Pfister, Corrado Gisonni

Former studies on combining flows resulted in an efficient layout of sewer junctions operated under supercritical approach flow conditions. Straight extensions allowed a reduction in the shock wave heights generated by the merging flows, so that the global ...

Renewable hydrogen generation from a dual-circuit redox flow battery

Hubert Girault, Christos Comninellis, Xile Hu, Heron Vrubel, Véronique Amstutz, Kathryn Ellen Toghill, Francis Powlesland

Redox flow batteries (RFBs) are particularly well suited for storing the intermittent excess supply of renewable electricity; so-called “junk” electricity. Conventional RFBs are charged and discharged electrochemically, with electricity stored as chemical ...

Dye Regeneration Dynamics by Electron Donors on Mesoscopic TiO2 Films

Michael Graetzel, Shaik Mohammed Zakeeruddin, Thomas Moehl

The influence of different redox mediators and electrolyte constituents on charge transfer processes in dye-sensitized solar cells (DSC) was studied by contactless transient photoconductance (TPC) measurements. Device subsets without FTO (Fluorine-doped ti ...

Influence of the Donor Size in D-pi-A Organic Dyes for Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Pascal Comte, Thomas Moehl, Chenyi Yi, Joël Teuscher, Thomas Wesley Holcombe, Jiabao Yang, Yongjoo Kim, Paramaguru Ganesan

We report two new molecularly engineered push-pull dyes, i.e., YA421 and YA422, based on substituted quinoxaline as a pi-conjugating linker and bulky-indoline moiety as donor and compared with reported IQ4 dye. Benefitting from increased steric hindrance w ...

Intrinsic toroidal rotation in the scrape-off layer of tokamaks

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

The origin and nature of intrinsic toroidal plasma rotation in the scrape-off-layer (SOL) of tokamaks is investigated both analytically and through numerical simulations. It is shown that the equilibrium poloidal E x B flow, the sheath physics, and the pre ...

Robust production of purified H-2 in a stable, self-regulating, and continuously operating solar fuel generator

Sophia Haussener, Miguel Antonio Modestino

The development of practical solar-driven electrochemical fuel generators requires the integration of light absorbing and electrochemical components into an architecture that must also provide easy separation of the product fuels. Unfortunately, many of th ...

A three-dimensional macroscopic fundamental diagram for mixed bi-modal urban networks

Nikolaos Geroliminis, Nan Zheng, Konstantinos Ampountolas

Recent research has studied the existence and the properties of a macroscopic fundamental diagram (MFD) for large urban networks. The MFD should not be universally expected as high scatter or hysteresis might appear for some type of networks, like heteroge ...
