Photogenerated Charge Harvesting and Recombination in Photocathodes of Solvent-Exfoliated WSe2

Understanding and optimizing the effects of edge states and nanoflake dimensions on the photon harvesting efficiency in ultrathin transition-metal dichalcogenide (TMD) semiconductor photoelectrodes is critical to assessing their practical viability for sol ...

A Decentralized Switched System Approach to Overvoltage Prevention in PV Residential Microgrids

Florian Dörfler, Pulkit Nahata

In this paper, we consider the problem of overvoltage arising in PV residential microgrids due to excessive power injection into the grid by the PV generators. We propose a decentralized switched controller to curtail excess active power in order to avoid ...

The electronic, chemical and electrocatalytic processes and intermediates on iron oxide surfaces during photoelectrochemical water splitting

Michael Graetzel, Artur Braun, Yelin Hu, Florent Alexandre Boudoire

We re-assess experimental soft X-ray absorption spectra of the oxygen K-shell which we recorded operando from iron oxide during photoelectrochemical water splitting in KOH electrolyte. In particular, we refer to recently reported transitional electron hole ...

Iron oxide nanoparticles supported on activated carbon fibers catalyze chemoselective reduction of nitroarenes under mild conditions

Lioubov Kiwi, Duncan Thomas Lindsay Alexander, Oliver Anthony Beswick

Highly dispersed iron oxide (Fe2O3) nanoparticles (NPs) have been immobilized on structured supports of activated carbon fibers (ACF). Systematic catalyst characterizations suggest that ACF-based catalysts remain ultra-microporous after Fe2O3 NPs (similar ...

Electrochemical behaviour of ferrocenes in tributylmethylphosphonium methyl sulfate mixtures with water and 1,2-dichloroethane

Thomas James Stockmann, Zhifeng Ding

Electron transfer (ET) reactions in ionic liquid (IL)vertical bar organic solvent (1,2-dichloroethane, DCE) and IL vertical bar water mixtures were investigated using a Pt disk ultramicroelectrode (UME) along with ferrocene (Fc) and ferrocenemethanol (FcCH ...

Flow microcapillary plasma mass spectrometry-based investigation of new Al–Cr–Fe complex metallic alloy passivation

Christian Ludwig, Noémie Elise Ott, Andrea Ulrich

Al-Cr-Fe complex metallic alloys are new intermetallic phases with low surface energy, low friction, and high corrosion resistance down to very low pH values (0-2). Flow microcapillary plasma mass spectrometry under potentiostatic control was used to chara ...

Tensile fatigue behaviour of Ultra-High Performance Fibre Reinforced Concrete combined with steel rebars (R-UHPFRC)

Eugen Brühwiler, Tohru Makita

Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) combined with steel rebars, subsequently called R-UHPFRC, is a promising building material implying a novel technology for the improvement of concrete structures. Steel rebars enhance effectively th ...

Effects of surface oxide formation on germanium nanowire band-edge photoluminescence

Shruti Thombare

The effect of intentional surface oxide formation on band-edge photoluminescence (PL) of Ge nanowires was investigated. Thermal oxidation in molecular O-2 was used to produce a surface oxide layer on assemblies of single crystal nanowires grown by the vapo ...

Direct growth of nanotubes and graphene nanoflowers on electrochemical platinum electrodes

Giovanni De Micheli, László Forró, Sandro Carrara, Arnaud Magrez, Federico Matteini, Irene Taurino

Multi-walled carbon nanotubes and graphene nanoflowers were grown by a catalytic chemical vapor deposition process on metal surfaces. Electrodeposition was used as a versatile technique to obtain three different iron catalyst coatings on platinum microelec ...
