Local structural investigation of hafnia-zirconia polymorphs in powders and thin films by X-ray absorption spectroscopy

Reinis Ignatans

Despite increasing attention for the recently found ferro- and antiferroelectric properties, the polymorphism in hafnia- and zirconia-based thin films is still not sufficiently understood. In the present work, we show that it is important to have a good qu ...

Dopaminergic modulation of motor network compensatory mechanisms in Parkinson's disease

Michael Herzog, Bogdan Draganski, Maya Anna Jastrzebowska, Renaud Marquis

The dopaminergic system has a unique gating function in the initiation and execution of movements. When the interhemispheric imbalance of dopamine inherent to the healthy brain is disrupted, as in Parkinson's disease (PD), compensatory mechanisms act to st ...

How Do London Dispersion Interactions Impact the Photochemical Processes of Molecular Switches?

Alberto Fabrizio

In the last two decades, linear-response time-dependent density functional theory (LR-TDDFT) has become one of the most widely used approaches for the computation of the excited-state properties of atoms and molecules. Despite its success in describing the ...

In Situ Tethering Strategies for the 3-Component Synthesis of Vicinal Amino Alcohols and Diamines via Pd-Catalyzed Carboetherification and Carboamination

Ugo Jonathan Orcel

Vicinal amino alcohols and diamines are privileged motifs in organic chemistry. As such, they have been targets of choice for exploring and developing novel and more efficient strategies in organic synthesis. In this context, the difunctionalization of ole ...

Mechanistic Aspects of the Formation of Adsorbable Organic Bromine during Chlorination of Bromide-containing Synthetic Waters

Urs von Gunten

During chlorination of bromide-containing waters, a significant formation of brominated disinfection byproducts is expected. This is of concern because Br-DBPs are generally more toxic than their chlorinated analogues. In this study, synthetic water sample ...

A molecularly engineered hole-​transporting material for efficient perovskite solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ulf Anders Hagfeldt, Peng Gao, Michael Saliba, Filippo de Angelis, Antonio Abate, Juan-Pablo Correa-Baena, Sadig Aghazada, Taisuke Matsui

Soln.-​processable perovskite solar cells have recently achieved certified power conversion efficiencies of over 20​%, challenging the long-​standing perception that high efficiencies must come at high costs. One major bottleneck for increasing the efficie ...

Zinc-gold cooperative catalysis for the direct alkynylation of benzofurans

Jérôme Waser, Yifan Li

The direct alkynylation of benzofurans was achieved for the first time using the hypervalent iodine reagent 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX) based on the cooperative effect between a gold catalyst and a zinc Lewis acid. H ...

Electrical Properties of Nb-, Ga-, and Y-Substituted Nanocrystalline Anatase TiO2 Prepared by Hydrothermal Synthesis

Michael Graetzel, Aravind Kumar Chandiran

Nanocrystalline anatase titanium dioxide powders were produced by a hydrothermal synthesis route in pure form and substituted with trivalent Ga3+ and Y3+ or pentavalent Nb5+ with the intention of creating acceptor or donor states, respectively. The electri ...

Selective three-phase hydrogenation of aromatic nitro-compounds over β-molybdenum nitride

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...
