Persistent enhancement of exciton diffusivity in CsPbBr3 nanocrystal solids
In semiconductors, exciton or charge carrier diffusivity is typically described as an inherent material property. Here, we show that the transport of excitons among CsPbBr3 perovskite nanocrystals (NCs) depends markedly on how recently those NCs were occup ...
Amer Assoc Advancement Science2024Controlling the crystal structure of succinic acid via microfluidic spray-drying
Esther Amstad, Aysu Ceren Okur
Many properties of materials, including their dissolution kinetics, hardness, and optical appearance, depend on their structure. Unfortunately, it is often difficult to control the structure of low molecular weight organic compounds that have a high propen ...
ROYAL SOC CHEMISTRY2023Metastability of the Potts Ferromagnet on Random Regular Graphs
We study the performance of Markov chains for the q-state ferromagnetic Potts model on random regular graphs. While the cases of the grid and the complete graph are by now well-understood, the case of random regular graphs has resisted a detailed analysis ...
SPRINGER2023Antagonistic interactions among structured domains in the multivalent Bicc1-ANKS3-ANKS6 protein network govern phase transitioning of target mRNAs
Daniel Constam, Benjamin Marcel Daniel Rothé, Céline Gagnieux, Simon Fortier, Céline Emmanuelle Schmuziger
The growing number of diseases linked to aberrant phase transitioning of ribonucleoproteins highlights the need to uncover how the interplay between multivalent protein and RNA interactions is regulated. Cytoplasmic granules of the RNA binding protein Bica ...
CELL PRESS2023Planted XY model: Thermodynamics and inference
Lenka Zdeborová, Guanhao Huang, Giovanni Piccioli, Siyu Chen
In this paper we study a fully connected planted spin glass named the planted XY model. Motivation for studying this system comes both from the spin glass field and the one of statistical inference where it models the angular synchronization problem. We d ...
2022Structural Measures as Guides to Ultrastable States in Overjammed Packings
Jammed, disordered packings of given sets of particles possess a multitude of equilibrium states with different mechanical properties. Identifying and constructing desired states, e.g., of superior stability, is a complex task. Here, we show that in two-di ...
2022Development of High-Strength Aluminum Alloys for Additive Manufacturing
Metal additive manufacturing (AM) offers the possibility to rapidly produce complex geometries that are not achievable with conventional manufacturing methods. The two most common technologies, Laser Powder Bed Fusion (LPBF) and Direct Metal Deposition (DM ...
EPFL2022Evidence of a transient phase during the hydrolysis of calcium-deficient hydroxyapatite
In the present paper, calcium deficient hydroxyapatite (Ca-def OHAP) has been examined in a transmission electron microscope. During the observation, the initial Ca-def OHAP was seen to transform first into a transient intermediate phase, then to a final, ...
WALTER DE GRUYTER GMBH2022Giant switchable non thermally-activated conduction in 180 degrees domain walls in tetragonal Pb(Zr,Ti)O-3
Mihai Adrian Ionescu, Igor Stolichnov, Felix Risch
Conductive domain walls in ferroelectrics offer a promising concept of nanoelectronic circuits with 2D domain-wall channels playing roles of memristors or synoptic interconnections. However, domain wall conduction remains challenging to control and pA-rang ...
NATURE PORTFOLIO2022Partial lifting of degeneracy in the J1-J2-J3 Ising antiferromagnet on the kagome lattice
Frédéric Mila, Jeanne Colbois, Andrew James Smerald
Motivated by dipolar-coupled artificial spin systems, we present a theoretical study of the classical J(1)-J(2)-J(3) Ising antiferromagnet on the kagome lattice. We establish the ground-state phase diagram of this model for J(1) > |J(2) |, |J(3) | based on ...
