PET-based prognostic survival model after radiotherapy for head and neck cancer

PurposeThe aims of this multicentre retrospective study of locally advanced head and neck cancer (LAHNC) treated with definitive radiotherapy were to (1) identify positron emission tomography (PET)-F-18-fluorodeoxyglucose (F-18-FDG) parameters correlated w ...

Stability of metallo-porphyrin networks under oxygen reduction and evolution conditions in alkaline media

Klaus Kern, Jan Gui-Hyon Dreiser, Markus Etzkorn, Claudius Morchutt, Sebastian Stepanow, Benjamin Wurster

Transition metal atoms stabilised by organic ligands or as oxides exhibit promising catalytic activity for the electrocatalytic reduction and evolution of oxygen. Built-up from earth-abundant elements, they offer affordable alternatives to precious-metal b ...

Oxygen Isotope Labeling Experiments Reveal Different Reaction Sites for the Oxygen Evolution Reaction on Nickel and Nickel Iron Oxides

Xile Hu, Magalí Alejandra Lingenfelder, Seunghwa Lee, Karla Banjac

Nickel iron oxide is considered a benchmark nonprecious catalyst for the oxygen evolution reaction (OER). However, the nature of the active site in nickel iron oxide is heavily debated. Here we report direct spectroscopic evidence for the different active ...

Effect of the Solvent on the Oxygen Evolution Reaction at the TiO2-Water Interface

Alfredo Pasquarello, Francesco Ambrosio, Patrick Gono

We investigate the solvation effect of water on the overpotentials of the oxygen evolution reaction on rutile TiO2 by applying the thermodynamic integration method on atomistic model interfaces with and without the water molecules. We compare the results a ...

An Unconventional Iron Nickel Catalyst for the Oxygen Evolution Reaction

Xile Hu, Michaël Bensimon, Fang Song, Michael Markus Busch, Elitsa Petkucheva

The oxygen evolution reaction (OER) is a key process that enables the storage of renewable energies in the form of chemical fuels. Here, we describe a catalyst that exhibits turnover frequencies higher than state-of-the-art catalysts that operate in alkali ...

An ultrathin cobalt-iron oxide catalyst for water oxidation on nanostructured hematite photoanodes

Xile Hu, Jingshan Luo, Laurent Liardet, Jordan Emanuel Katz

The harvesting of sunlight by a photoelectrochemical (PEC) cell to split water into hydrogen and oxygen is an attractive strategy to store solar energy in the form of chemical bonds. The oxygen evolution reaction (OER) remains a bottleneck for the developm ...

Ethynylbenziodazolones (EBZ) as Electrophilic Alkynylation Reagents for the Highly Enantioselective Copper-Catalyzed Oxyalkynylation of Diazo Compounds

Rosario Scopelliti, Jérôme Waser, Farzaneh Fadaei Tirani, Durga Prasada Rao Hari, Lionel Schouwey, Verity Barber

Ethynylbenziodoxol(on)e (EBX) cyclic hypervalent iodine reagents are now established reagents for the alkynylation of radicals and nucleophiles, yet they present limited possibilities for further structure and reactivity modification. Herein, the first syn ...

Dissolution-reprecipitation reaction of dolomite: investigation of self- and tracer-diffusion using SIMS mini-spot and NanoSIMS profiles

Anders Meibom, Stéphane Laurent Escrig, Lukas Baumgartner

Recrystallization of minerals due to fluid infiltration modifies their original chemical and isotopic signature. Such processes are sought after as they give access to timescales of geologic processes, which are commonly quantified using diffusion chronome ...

Trellises of Molecular Oxygen on Anatase TiO2(101)

Klaus Kern, Christian Alexander Stephan Dette, Feliciano Giustino, Shai Mangel

The adsorption of molecular oxygen has important implications for the catalytic activity of oxide surfaces, especially for oxidative TiO2 catalysts. In the case of anatase TiO2(101), several studies have noted the importance of surface defects which stabil ...
