Photorealistic modelling of metals from first principles

Nicola Marzari, Gianluca Prandini, Gian-Marco Rignanese

The colours of metals have attracted the attention of humanity since ancient times, and coloured metals, in particular gold compounds, have been employed for tools and objects symbolizing the aesthetics of power. In this work, we develop a comprehensive fr ...

Universal Oxide Shell Growth Enables in Situ Structural Studies of Perovskite Nanocrystals during the Anion Exchange Reaction

Raffaella Buonsanti, Anna Loiudice, Seryio Saris, Michal Stanislaw Strach

The ability to tune thin oxide coatings by wet-chemistry is desirable for many applications, yet it remains a key synthetic challenge. In this work, we introduce a general colloidal atomic layer deposition (c-ALD) synthesis to grow an alumina shell with tu ...

Discovery of a self-healing catalyst for the hydrolytic dehydrogenation of ammonia borane

Emad Oveisi, Mounir Driss Mensi, Fatmah Ebrahim, Kyriakos Stylianou, Ngoc Tú Nguyên, Andrzej Gladysiak, Bardiya Valizadeh, Fatma Pelin Uran

Sustainable catalysts based on earth-abundant elements are considered as economical alternatives to precious-metal-bearing catalysts and could be impactful for many applications. Self-healing sustainable catalysts, which in addition to their 'green' charac ...

CO2 hydrogenation reaction over pristine Fe, Co, Ni, Cu and Al2O3 supported Ru: Comparison and determination of the activation energies

Noris André Gallandat, Emanuele Moioli, Wen Luo, Robin Tobias Andreas Mutschler

Fe, Co, Ni and Cu are the main non-noble industrially significant catalysts in the CO2 and CO gas phase hydrogenation reaction towards hydrocarbons and alcohols. These catalysts are typically supported on metal oxides such as SiO2, TiO2, Al2O3 and ZnO, in ...

Predicting yield strengths of noble metal high entropy alloys

William Curtin, Céline Varvenne

Recent data on the Noble metal (Pd-Pt-Rh-Ir-Au-Ag-Cu-Ni) high entropy alloys (HEAs) shows some of these materials to have impressive mechanical properties. Here, a mechanistic theory for the temperature-, composition-, and strain-rate-dependence of the ini ...

The industrial production of aromatic amines, essential intermediates for the synthesis of several drugs, dyes, pigments and agrochemicals, requires the use of heterogeneous catalysis. These molecules were formerly produced by the Béchamp reduction, a non- ...

EPFL2017

Proton exchange membrane water electrolysis (PEMWE) is a promising technology for electricity-to-fuel conversion which allows for direct production of hydrogen from water. One of the key problems limiting widespread implementation of PEMWE into energy syst ...

Magnetoelectric micromachines with wirelessly controlled navigation and functionality

Mahmut Selman Sakar

The use of a single energy source for both manipulating micromachines and triggering their functionalities will result in highly integrated devices and simplify the design of the controlling platform. Here, we demonstrate this concept employing magnetoelec ...
