GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching

Advanced Functional Materials, EarlyView.
The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Novel structures for optimal space partitions

New Journal of Physics, 2016
Partitioning space into polyhedra with a minimum total surface area is a fundamental question in science and mathematics. In 1887, Lord Kelvin conjectured that the optimal partition of space is obtained with a 14-faced space-filling polyhedron, called ...

Engineering Intraframework Energy Transfer in Metal‐Organic Frameworks for Luminescent Discrimination of Bisphenol Pollutants

Advanced Functional Materials, EarlyView.
A family of isostructural lanthanide metal–organic frameworks serves as a model platform to disentangle metal‐to‐metal and linker‐to‐linker energy transfer during luminescence sensing. The results reveal that rigid lanthanide energy migration governs sensing performance, whereas linker‐mediated pathways exert only minor effects, providing mechanistic ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Space Tessellations. Polyhedral Sculpting

Symmetry: Art and Science | 12th SIS-Symmetry Congress, 2022
At the Institute for Art and Design, a subunit of the Department of Architecture at TU Wien, every year, a non-mandatory artistic project is organized, open for Master Students (5 ECTS points). I will report on the development and the outcomes of this assignment, a research and de- sign project in the realm of sculpting based on polyhedral aggregations,

Influence of POSS Type on the Space Environment Durability of Epoxy-POSS Nanocomposites

Nanomaterials, 2022
In order to use polymers at low Earth orbit (LEO) environment, they must be protected against atomic oxygen (AO) erosion. A promising protection strategy is to incorporate polyhedral oligomeric silsesquioxane (POSS) molecules into the polymer backbone ...
