Near-Field Ptychographic Tomography on Freeze-Quenched Liquids Using CryoTEM Methods

William CHEVREMONT · Frédéric GOBEAUX · Johannes IHLI · Mark LEVENSTEIN · y 3 más

In materials chemistry, there is currently intense debate on the nature of non-classical phases that form as precursors to crystalline materials: are they true thermodynamic phases or simply mixing heterogeneities? To date, neither case has been demonstrated conclusively. The goal of this proposal is to use cryogenic n...

Exploring gelation and contact aging in colloidal gels: Insights from casein micelles with tuneable softness

Florence ROUSSEAU · Fanny GUYOMARC'H · Erik JUSTE · Thomas CROGUENNEC · y 4 más

Enzymatic milk gels result from the destabilization of casein micelles, which are natural colloids found in milk. After aggregation, these soft particles have been shown to display “contact-aging”, i.e. the reinforcement of their contact or “sintering” over time. This microscopic mechanism may drive the pronounced stru...

Regularized Estimation of High-Dimensional Matrix-Variate Autoregressive Models

Jiang, Hangjin · Shen, Baining · Li, Yuzhou · Gao, Zhaoxing

Matrix-variate time series data are increasingly popular in economics, statistics, and environmental studies, among other fields. This paper develops regularized estimation methods for analyzing high-dimensional matrix-variate time series using bilinear matrix-variate autoregressive models. The bilinear autoregressive...

Structural Characterization of Consensus TetratricoPeptide Repeat (CTPR) Protein Nanoparticles via SAXS

Petra PERNOT · Paolo BLESIO · Paula MALO DE MOLINA

Ultra-small protein single-chain nanoparticles (SCNPs) offer promising potential for biomedical applications. Building on advances in synthetic polymer chain collapse through intramolecular cross-linking, this proposal aims to apply these principles to proteins using bioengineered Consensus TetratricoPeptide Repeat (CT...

The Israeli BAG

SIHYUN SUNG · Oded LIVNAH · Moshe DESSAU · Adarsh PATEL · y 1 más

The Israeli BAG plans to increase its usage of ESRF in the coming year. We are having more projects that utilize the ESRF single crystal capabilities as well as the continuous increase in SAXS time. As mentioned last year It is not trivial to provide a summary that covers all research topics encompassed by the BAG. We...

In-situ combined X-ray powder diffraction and vibrational spectroscopy study on SrO-based CO2 sorbents for Direct Air Capture applications

Mathilde JACQ · Diana PIANKOVA · Dominik RICHERT · Dmitry CHERNYSHOV · y 1 más

The goal of this project is to improve our understanding of the carbonation, hydration, and regeneration reactions within the strontium oxide - strontium carbonate (SrO-SrCO3) system. This knowledge is crucial for the development SrO-based materials for the direct air capture (DAC) of carbon dioxide (CO2). In situ X-ra...

Chasing crucial stages of ultrafast FAU-to-AEI interzeolite conversion by operando spectroscopy

Martin ROSENTHAL · Elena BROZZI · Sven ROBIJNS · Gleb IVANUSHKIN · y 1 más

Zeolites are molecular sieves that hold great importance in the field of catalysis, where they are used as (both) an active phase and/or a catalyst support. Here, we aim to study the interzeolite crystallization process of a FAU mixture to AEI, utilizing SAXS/WAXS techniques. As a result, engaging the studied mechanism...

Investigating the structural origin of luminescence in lanthanide-based metal-organic frameworks.

Tommaso GENTILI · Paola D'ANGELO · Alessandro TOFONI · Davide SALUSSO · y 1 más

Lanthanide-based metal-organic frameworks (MOFs) exhibit highly promising photoluminescent properties as these materials can emit light from the visible to the near-infrared regions due to the unique 4f-orbital electronic structure of the lanthanide nodes. While down-shifting emission is the most common luminescence pr...

Hydrogen in the Earth’s core: Sound velocities of hydrogen bearing Fe-Si-alloys at extreme conditions

Xiang LI · DENNIS KOSOBOKOV · Georgios APRILIS · Ilya KUPENKO · y 2 más

In this experiment, we aim to investigate the density as well as the electronic, elastic and thermodynamic properties of hydrogen-bearing Fe-Si-alloys at pressures above 300 GPa and temperatures up to several thousands of degrees. Therefore, nuclear inelastic scattering (NIS) and powder x-ray diffraction (XRD) are plan...
