Columnlike free-interface flows: symmetry breaking and linear instability

This thesis is dedicated to the analysis of a subclass of interfacial flows, columnlike free-interface flows, from two view angles: (i) the symmetry breaking under geometry-induced or external forces, (ii) their stability against infinitesimal disturbances ...

Voltage-driven Reactivity of Liquid Ga and CuGa Nanoparticles for Electrocatalytic CO2 Reduction and Synthesis

Valery Okatenko

The rising atmospheric level of carbon dioxide, CO2, contributes to climate change and poses urgent need to find scalable solutions both to decrease its emissions and to be able to recycle it, if the goals of Paris Agreement to limit the temperature rise a ...

Enhancement of Pressure-Sensitive Adhesive by CO2 Laser Treatment

Dario Floreano, Yegor Piskarev, Jun Shintake, Vivek Ramachandran, Michael Dickey, Jianhang Yang

Pressure-sensitive adhesives (PSAs) are polymeric films that can be adhered to and detached from surfaces without leaving residue. Researchers are looking to enhance the bond strength between PSAs and different substrates. It can be achieved by tuning PSA' ...

Using collective knowledge to assign oxidation states of metal cations in metal-organic frameworks

Berend Smit, Seyedmohamad Moosavi, Daniele Ongari, Kevin Maik Jablonka

Knowledge of the oxidation state of metal centres in compounds and materials helps in the understanding of their chemical bonding and properties. Chemists have developed theories to predict oxidation states based on electron-counting rules, but these can f ...

C-C bond activation enabled by dyotropic rearrangement of Pd(iv) species

Qian Wang, Jieping Zhu, Hua Wu, Jian Cao

The weak carbon-metal bond combined with the kinetic inertness of the carbon-carbon bond renders metal-catalysed C-C bond activation to be highly challenging. Most of the reported C-C bond activation methodologies involve strain-releasing cleavage of small ...

Shear behavior of single- and triple-thickness masonry panels strengthened by bed-joint structural repointing

Ricardo Javier Serpell Carriquiry

Bed-joint structural repointing is a widely used strengthening technique in historic masonry constructions, particularly in applications where the material appearance needs to be preserved. Despite its wide use, limited research is available on the effecti ...

Evidence of a coupled electron-phonon liquid in NbGe2

Mathieu François Padlewski, Matthias Carsten Putzke, Philip Johannes Walter Moll, Hao Yang

Whereas electron-phonon scattering relaxes the electron's momentum in metals, a perpetual exchange of momentum between phonons and electrons may conserve total momentum and lead to a coupled electron-phonon liquid. Such a phase of matter could be a platfor ...

Band alignment at beta-Ga2O3/III-N (III = Al, Ga) interfaces through hybrid functional calculations

Alfredo Pasquarello, Sai Lyu

The band alignment and the chemical bonding at the beta -Ga2O3/AlN and beta -Ga2O3/GaN interfaces are studied through hybrid functional calculations. We construct realistic slab models with III-O (III = Al, Ga) bonds dominating the chemical bonding at both ...
