Published in 2019 at "Advanced materials"

DOI: 10.1002/adma.201900323

Abstract: Single-atom catalysts (SACs) aim at bridging the gap between homogeneous and heterogeneous catalysis. The challenge is the development of materials with ligands enabling coordination of metal atoms in different valence states, and preventing leaching or… read more here.

Published in 2022 at "Advanced Science"

DOI: 10.1002/advs.202200640

Abstract: Motivation and its hedonic valence are powerful modulators of sleep/wake behavior, yet its underlying mechanism is still poorly understood. Given the well‐established role of midbrain dopamine (mDA) neurons in encoding motivation and emotional valence, here,… read more here.

Published in 2023 at "Advanced science"

DOI: 10.1002/advs.202206342

Abstract: MnTe has been considered a promising candidate for lead-free mid-temperature range thermoelectric clean energy conversions. However, the widespread use of this technology is constrained by the relatively low-cost performance of materials. Developing environmentally friendly thermoelectrics… read more here.

Published in 2017 at "Journal of Consumer Behaviour"

DOI: 10.1002/cb.1647

Abstract: Whereas previous studies investigated the affect transfer from one specific affective stimulus of the brand placement context (such as an artist or the genre) to the brand, this research study investigates the effect of the… read more here.

Published in 2017 at "Depression and Anxiety"

DOI: 10.1002/da.22656

Abstract: Internalizing disorders (IDs), consisting of the syndromes of anxiety and depression, are common, debilitating conditions often having onsets in adolescence. Scientists have developed dimensional self‐report instruments that assess putative negative valence system (NVS) trait‐like constructs… read more here.

Published in 2019 at "Hippocampus"

DOI: 10.1002/hipo.23143

Abstract: Sleep is important for memory consolidation, and an abundant literature suggests that reactivation in the hippocampus during sleep is instrumental to this process. Yet, the current interpretation of activity during sharp‐waves ripples (SWRs), as replay… read more here.

Published in 2022 at "Journal of Computational Chemistry"

DOI: 10.1002/jcc.26845

Abstract: Density functional theory (DFT) is used to explore the structure, stability, and bonding in CSiGaAl2−/0 and CGeGaAl2−/0 systems having planar tetracoordinate carbon (ptC). The neutral systems have 17 valence electrons and the mono‐anionic systems have… read more here.

Published in 2022 at "Small"

DOI: 10.1002/smll.202200303

Abstract: High-valence metal-doped multimetal (oxy)hydroxides outperform noble metal electrocatalysts for the oxygen evolution reaction (OER) owing to the modified energetics between 3d metals and high-valence dopants. However, the rational design of sufficient and subtle modulators is… read more here.

Published in 2020 at "Theoretical Chemistry Accounts"

DOI: 10.1007/s00214-020-02649-1

Abstract: Does the optically bright $$B_2(\pi \rightarrow \pi ^*)$$ transition in pyrrole correspond to an inter-valence or to a mixed valence–Rydberg transition? State-of-the-art electronic structure methods provide inconclusive results and relegate the answer to future time-resolved… read more here.

Published in 2017 at "Journal of Autism and Developmental Disorders"

DOI: 10.1007/s10803-016-3017-9

Abstract: Adolescents with and without autism spectrum disorder (ASD) performed two priming experiments in which they implicitly processed a prime stimulus, containing high and/or low spatial frequency information, and then explicitly categorized a target face either… read more here.
