Understanding the effects of material properties and operating conditions on component aging in polymer electrolyte water electrolyzers

Ugljesa Babic, Mohamed Tarik, Thomas Justus Schmidt

If polymer electrolyte water electrolysis (PEWE) is to penetrate the energy market in the context of power-to-x, challenges related to component durability need to be understood and addressed. In this study, PEWE component degradation mechanisms are induce ...

Selective, Fast-Response, and Regenerable Metal-Organic Framework for Sampling Excess Fluoride Levels in Drinking Water

Paul Joseph Dyson, Fatmah Ebrahim, Serhii Shyshkanov, Patrick Favre, Kyriakos Stylianou, Ngoc Tú Nguyên, Andrzej Gladysiak

Prolonged consumption of water contaminated with fluoride ions (F-) at concentrations exceeding 1.5 ppm can lead to considerable health implications, particularly in children and developing embryos. With irreversible and potentially severe forms of fluorid ...

Divergent Synthesis of Densely Substituted Arenes and Pyridines via Cyclotrimerization Reactions of Alkynyl Triazenes

Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Florian Gérald Abela, Jin Fay Tan, Frederick Mark Chadwick

Densely substituted fused aromatic triazenes can be prepared by [2 + 2 + 2] cyclotrimerization reactions of 1-alkynyl triazenes. The Cp*Ru-catalyzed cyclization proceeds well with both simple alkynyl triazenes and tethered 1-diynyl triazenes. Attractively, ...

Corrosion behaviour of Ti6A14V ELI nanotubes for biomedical applications

Surfaces engineering on titanium biomedical alloys aiming for improving bone regeneration, healing periods and increasing lifetime needs fora fundamental understanding of the electrochemical reactions occurring at the interface biomaterial/human fluid. The ...

Catalyst design for the transformation of CO2 into value-added products.

Felix Daniel Bobbink

The mass-utilization of fossil resources has led to a dramatic increase in carbon dioxide (CO2) production, most of which is released directly into the Earth's atmosphere, resulting in global warming. Efforts to contain CO2 emissions and to capture, store ...

Calcium impurity as a source of non-radiative recombination in (In,Ga)N layers grown by molecular beam epitaxy

Nicolas Grandjean

Ca as an unintentional impurity has been investigated in III-nitride layers grown by molecular beam epitaxy (MBE). It is found that Ca originates from the substrate surface, even if careful cleaning and rinsing procedures are applied. The initial Ca surfac ...

Strontium hydroxyapatite and strontium carbonate as templates for the precipitation of calcium-phosphates in the absence and presence of fluoride

Janet Gordon Hering, Michèle Bernadette Heeb

The heterogeneous precipitation of calcium phosphates on calcium hydroxyapariLe (Ca-10(PO4)(4)OH)(2) or HAP) in the presence arid absence of fluoride is important in the formation of bone and teeth, protection against tooth decay, dental and skeletal fluor ...

Mid-infrared optical frequency combs at 2.5 mu m based on crystalline microresonators

Tobias Kippenberg, Albert Schliesser, Tobias Herr

The mid-infrared spectral range (lambda similar to 2-20 mu m) is of particular importance as many molecules exhibit strong vibrational fingerprints in this region. Optical frequency combs-broadband optical sources consisting of equally spaced and mutually ...

The effect of NaF in vitro on the mechanical and material properties of trabecular and cortical bone

Blake William Erickson

High doses of sodium fluoride in bones lead to severe softening, by weakening interfacial properties between the inorg. minerals and the org. components, while leaving mineralization unchanged. This leads to redn. of microdamage and assocd. stress-whitenin ...

Effect of fluoride plasma treatment on InAlN/GaN HEMTs

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Marcel Py, Marcus Gonschorek

Fluoride plasma treatment similar to that used in AlGaN/GaN HEMTs has been applied to InAlN/GaN HEMTs. Enhancement mode of operation is obtained with a pinch-off voltage shifted by 3 V. Owing to the fluoride treatment an increase of the forward gate thresh ...
