Synthesis and Reactivity of an Anionic Diazoolefin
Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Bastiaan Kooij, Zhaowen Dong
Bent (hetero)allenes such as carbodicarbenes and carbodiphosphoranes can act as neutral C-donor ligands, and diverse applications in coordination chemistry have been reported. N-Heterocyclic diazoolefins are heterocumulenes, which can function in a similar ...
2023Decoupling the Contributions of Different Instability Mechanisms to the PEMFC Performance Decay of Non-noble Metal O2-Reduction Catalysts
Vasiliki Tileli, Robin Pierre Alain Girod, Secil Unsal
Non-noble metal catalysts (NNMCs) hold the potential to replace the expensive Pt-based materials currently used to speed up the oxygen reduction reaction (ORR) in proton exchange membrane fuel cell (PEMFC) cathodes, but they feature poor durability that in ...
AMER CHEMICAL SOC2023Exfoliated 2D Layered and Nonlayered Metal Phosphorous Trichalcogenides Nanosheets as Promising Electrocatalysts for CO2 Reduction
Michael Graetzel, Hong Zhang, Dan Ren, Yelin Hu, Yunfei Jiao, Bing Wu, Chen Shen, Fei Liang
Two-dimensional (2D) materials catalysts provide an atomic-scale view on a fascinating arena for understanding the mechanism of electrocatalytic carbon dioxide reduction (CO2 ECR). Here, we successfully exfoliated both layered and nonlayered ultra-thin met ...
WILEY-V C H VERLAG GMBH2023Resonant Inelastic X-Ray Scattering Study of Electron-Exciton Coupling in High-T-c Cuprates
Fabrizio Carbone, Thorsten Schmitt, Ivan Madan, Christophe Berthod, Francesco Barantani, Yi Tseng, Dirk Van der Marel
Explaining the mechanism of superconductivity in the high-T-c cuprates requires an understanding of what causes electrons to form Cooper pairs. Pairing can be mediated by phonons, the screened Coulomb force, spin or charge fluctuations, excitons, or by a c ...
AMER PHYSICAL SOC2022Phase transition of layer-stacked borophene under pressure
Oleg Yazyev, Quansheng Wu, Xiao Dong
The 8-Pmmn borophene, a boron analog of graphene, hosts tilted and anisotropic massless Dirac fermion quasiparticles owing to the presence of a distorted graphenelike sublattice. First-principles calculations show that stacked 8-Pmmn borophene is transform ...
AMER PHYSICAL SOC2022Assessment of metal-based dihydrofolate reductase inhibitors on a novel mesofluidic platform
Paul Joseph Dyson, Sarah Alexandra Pais Pereira
A new miniaturized micro sequential injection coupled with the lab-on-valve (mu SIA-LOV) technique was full-blown to perform inhibitory studies on dihydrofolate reductase (DHFR). The system was used to evaluate the DHFR inhibition activity of metal-based a ...
ELSEVIER SCIENCE SA2022Development of remote C-H bond functionalization of redox-active alcohol derivatives and oxidative transformations under photoredox catalysis
Alexandre Julien Florent Leclair
The development of radical-based remote C(sp3)-H functionalizations of redox-active alcohol derivatives, oxidative cycloaddition and rearrangement transformations under visible light photocatalysis constitute the basis of this thesis.The first chapter desc ...
EPFL2021Confinement of fluorine anions in nickel-based catalysts for greatly enhancing oxygen evolution activity
Herein, we highlighted fluorine-anion-modification as a useful method for enhancing OER catalytic activity. Fluorine-anion-doped Ni foam exhibits an almost 10-fold enhancement in OER catalytic activity. Moreover, fluorine-anion-modification could be used a ...
ROYAL SOC CHEMISTRY2020Ab Initio Flexible Force Field for Metal-Organic Frameworks Using Dummy Model Coordination Bonds
Berend Smit, Seyedmohamad Moosavi, Matthew David Witman, Sudabeh Jawahery, Nakul Rampal
We present force fields developed from periodic density functional theory (DFT) calculations that can be used in classical molecular simulations to model M MOF-74 (M = Co, Fe, Mg, Mn, Ni, Zn) and its extended linker analogs. Our force fields are based on c ...

Philippe Gillet, Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri
Gas hydrates consist of hydrogen-bonded water frameworks enclosing guest gas molecules and have been the focus of intense research for almost 40 y, both for their fundamental role in the understanding of hydrophobic interactions and for gas storage and ene ...
