Impact of Hydrocarbon Chain Ligands on the Stability of Dispersed Small Nanoparticles

Yehon LEVY · Elad OZERI · Gilbert CHAHINE · Isabelle MORFIN · y 2 más

An ongoing challenge in the field of semiconductor nanoparticles (NPs) is to increase their solubility, particularly in apolar solvents, where the colloidal stability of NPs is typically limited, and relevant theoretical treatment is lacking. One common strategy to increase this stability involves modifying the NP-graf...

Reconstructing Integumentary Innovation in Mammals and Dinosaurs from the Lower Cretaceous: Insights from Las Hoyas Fossils

Federico COVA · Hugo MARTIN · Jesús MARUGÁN · Kathleen DOLLMAN

The Lower Cretaceous was a period of major evolutionary innovation for plants and animals, especially in wetlands. The Las Hoyas fossil site (125–129 Mya) provides an exceptional record of this, preserving a nearly complete wetland ecosystem with detailed bone and soft tissue fossils.This project focuses on reconstruct...

Probing the N2 activation at the metal/LaN interface with N K edge RIXS

Guanghan ZHU · Xin DENG · Feng Ryan WANG (ORCID: 0000-0002-2475-606X) · Haoxin LIU · y 2 más

NH3 is one of the most important chemical products and is responsible for fertilizer production. NH3 synthesis from N2 is the current commercial process but suffers from the high activation barrier of N2, requiring 400-500 C and 150-300 bar operation conditions. Towards low temperature and pressure NH3 synthesis, we ha...

In Operando Investigation of the Gate Opening Process in Metal Organic Frameworks

Tao ZHOU · Dina SHEYFER · Jiangtao ZHAO · Tugba ISIK · y 2 más

Metal-organic frameworks (MOFs) are crystalline, modular, and porous materials used in catalysis, gas separation, and storage. Some MOFs exhibit "gate-opening" behavior, where structural changes upon gas exposure allow selective separation via preferential coordination, aiding in the recovery of gases like helium and a...

Tensor tomography of shark vertebral centra tissue

Dominique WINDISCH · NICOLAS CHARPENTIER · Marianne LIEBI · Mads CARLSEN · y 1 más

With rapidly accelerating climate change, populations of many marine species are at high risk, especially slowly reproducing apex predators like sharks. Growth bands in shark vertebral centra are used to estimate age, and numerous sub-bands exist, confounding band counts and negatively affecting population estimates an...

In-situ diffraction investigation of the structural evolution of a symmetric electrolytic cell device working reversibly in SOFC and SOEC co

Jakub DRNEC · Jonathan CAVAZZANI · Pietro TRAINOTTI · Davide CHINELLO · y 1 más

Solid Oxide Cells (SOC) devices are featured by reversibility since they can work in both SOFC (F=Fuel) and SOEC (E=Electrolysis) mode. Current electrolyte materials suffer of particles agglomeration and C poisoning reducing lifetime and performance. Very recently, advanced electrocatalysts, were metal nanoparticles ar...

Bridging the gap between cellular and whole body imaging using Hierarchical Phase-Contrast Tomography: HiP-CT

Bellier, Alexandre · Brunet, Joseph · Docter, Daniel · Lee, Peter · y 7 más

Humans and other large organisms are three-dimensional multiscale biological systems where large scale function and structure are dependent on the macrostructure’s interconnectivity down to the cellular and subcellular level. Using the exceptional coherence provided by the ESRF-EBS, we have demonstrated that propagatio...

Structural bases of striated muscle contraction

Vincenzo LOMBARDI · Mariano BALZANO · Marco LINARI · Pasquale BIANCO · y 4 más

Muscle contraction is regulated by both Ca2+ dependent thin filament activation and mechanosensing-based thick filament activation. Evidence is growing for the involvement in thick filament regulation of the cytoskeleton protein titin, which runs from the midpoint of the thick filament to the end of the sarcomere, and...
