materials Xploration - on the discovery of new materials
High-pressure materials genome - taking materials discovery to the next level Many known materials are not thermodynamically stable, but exist as metastable states which are kinetically protected. This behavior is analogous…
Higher pressure ⇒ denser packing ⇒ better superconductivity! Recently, we had reported the discovery of novel Cu-Bi phases at elevated pressures. Both the Cu11Bi7 and CuBi compounds have unexpected low densities, with…
How to force elements to bond Most non-elemental materials that we know have been synthesized using chemical processes that occur at conditions close to what we call "ambient", meaning with temperatures within a few hundred…
Discovery of ultralow thermal conductivity in new Heusler compounds Semiconducting half and, to a lesser extent, full Heusler compounds are promising thermoelectric materials due to their compelling electronic properties…
LASSP Special Seminar - Cornell In silico materials design: porous high-pressure intermetallics and rattling Heusler compounds. I will give a talk on my recent reserach results at the Cornell University. The talk will…
Kickoff I am delighted to announce the launch of Materials X, my personal platform reporting on discoveries in the area of materials exploration.

Welcome to Materials X!
My name is Maximilian Amsler and I am a researcher in the field of materials exploration. Using computational methods, I discover, design and study the properties of various materials. My research takes place in an interdisciplinary environment, where physics, chemistry and materials science meet to investigate exciting phenomena in condensed matter.
Recently, we had reported the discovery of novel Cu-Bi phases at elevated pressures. Both the Cu11Bi7 and CuBi compounds have unexpected low densities, with one and two dimensional channels running through the materials. We showed that these voids are not completely empty, but provide room for the stereochemically active bismuth lone electron pairs. Such low density Read More ...
Machine learning is a technique that was developed in the field of computer science, but is meanwhile rapidly spreading for applications in many other disciplines. Originally intended as a tool for pattern recognition, machine learning algorithms can be taught to extract trends in large data-sets, which can then be used to make accurate predictions beyond the Read More ...
Most non-elemental materials that we know have been synthesized using chemical processes that occur at conditions close to what we call “ambient”, meaning with temperatures within a few hundred °C and at atmospheric pressures. At these conditions, many elements react with each other and form compounds. However, there are some exceptional elements that simply will Read More ...
The surface of our earth only exposes a fraction of matter the planet is made of, and most of it lies below the earth’s crust, where the pressure and temperatures differ significantly from ambient conditions. At the core of the earth, the pressures are as high as 360 GPa, more than three million times the Read More ...
Materials properties are very closely linked to the underlying crystal structure, the way how atoms or molecules are arranged in the crystal lattice. The knowledge of the atomic arrangement is the very first and most important information one needs to study and understand a material. Crystal structure prediction (CSP) methods are techniques to determine the Read More ...
Superconductivity, the phenomenon of vanishing electrical resistivity, was first discovered by the Dutch physicist Heike Kamerlingh Onnes in 1911 when he was able to produce liquid helium and cool mercury down to below 4.2 K. At that time, it was not known how the conductivity of a metal would behave if the temperature was reduced Read More ...
At the beginning of the current century we are facing massive challenges due to the increasing global demand for energy, focused on two major issues. On one hand, conventional fossil fuel resources such as oil, natural gas and coal are limited and dwindling. On the other hand, the emissions due to combustion of fossil fuels Read More ...
