Modeling non-covalent interactions in condensed phase

The modeling of non-covalent interactions, solvation effects, and chemical reactions in complex molecular environment is a challenging task. Current state-of-the-art approaches often rely on static computations using implicit solvent models and harmonic ap ...

The Status Quo of Rashba Phenomena in Organic-Inorganic Hybrid Perovskites

Mohammad Khaja Nazeeruddin

In this Perspective, we address the fundamentals and possible implications of Rashba phenomena particularly for noncentrosymmetric and heavy element-containing hybrid perovskite systems. The work sheds light on the application paradigm of these exciting ph ...

Ultralow-Profile Circularly Polarized Reflectarray Antenna for CubeSat Intersatellite Links in K-B and

Anja Skrivervik, Miroslav Veljovic

An ultralow-profile circularly polarized (CP) reflectarray (RA) antenna is presented in this article, based on the variable-rotation technique for beam collimation and scanning. Starting from a conventional split-loop element, a new wideband element is des ...

A three-dimensional macroelement for modelling the in-plane and out-of-plane response of masonry walls

Katrin Beyer, Francesco Vanin, Andrea Penna

The seismic performance of unreinforced masonry buildings is commonly assessed using equivalent frame modelling. Its computational efficiency allows for a large number of analyses to be conducted, which are often required to account for epistemic and aleat ...

Bosonic superfluid transport in a quantum point contact

Jean-Philippe Brantut

We present a microscopic theory of heat and particle transport of an interacting, low-temperature Bose- Einstein condensate in a quantum point contact.We show that, in contrast to charged, fermionic superconductors, bosonic systems feature tunneling proces ...

Optimum design of frame structures from a stock of reclaimed elements

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

This paper presents optimization methods to design frame structures from a stock of existing elements. These methods are relevant when reusing structural elements over multiple service lives. Reuse has the potential to reduce the environmental impact of bu ...

The Pristine survey IV: approaching the Galactic metallicity floor with the discovery of an ultra-metal-poor star

Pascale Jablonka, Carmela Lardo, Nicolas Lawrence Etienne Longeard, Marc Gentile, Silvia Martin de Nicolas Agut

The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Galactic stages, but are exceedingly rare and difficult to find. Here, we presen ...

Optimization Formulations for the Design of Low Embodied Energy Structures Made from Reused Elements

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

The building sector is one of the major contributors to material resource consumption, greenhouse gas emission and waste production. Load-bearing systems have a particularly large environmental impact because of their material and energy intensive manufact ...

Description of the capacity degradation mechanism in LaNi5-based alloy electrodes

Andreas Züttel, Philippe Mauron, Mariana Spodaryk, Marco Roman Holzer

The mechanism of the capacity degradation of LaNi5-based alloy electrodes was investigated with a special focus on the influence of the alloy and surface composition, as well as the unique structure obtained by gas atomisation. The electrochemical properti ...

Room temperature concurrent formation of ultra-dense arrays of ferroelectric domain walls

Nava Setter, Alexander Tagantsev, Petr Yudin, Ludwig Feigl, Mahamudu Mtebwa, Konstantin Shapovalov

Properties of ferroelectric domain walls are attractive for future nano- and optoelectronics. An important element is the potential to electrically erase/rewrite domain walls inside working devices. Dense domain wall patterns, formed upon cooling through t ...
