Innovative operando HERFD-XAS characterization of diluted Cs promoters on Ag/alpha-Al2O3 as catalysts for ethylene epoxidation

Antonio AGUILAR · Samy OULD-CHIKH · Olivier PROUX · Ahmed ZIANI

Silver-based nanoparticle catalysts supported on alpha alumina are widely used for ethylene oxide production. Caesium alkali promoters, such as Cs oxide and Cs rhenate, are essential for improving selectivity. However, the molecular and electronic details of Cs species remain unknown. X-ray absorption spectroscopy with...

Foliar amino acid δ15N patterns reflect aridity and plant structure with implications for consumer diet reconstruction

Sean W. Hixon · Daniel Giddings Vassão · Ricardo Fernandes · Jörg U. Ganzhorn · y 8 más

Compound specific amino acid (AA) nitrogen isotope (δ15N) analysis complements direct observations by revealing food web structure and ecological interactions, yet interpretation of consumer δ15N values depends on understanding natural variability in autotroph AA δ15N values. To test hypotheses about how foliar AA δ15N...

On the model theory of second-order objects

Tapani Hyttinen · Joni Puljujärvi · Davide Emilio Quadrellaro

Motivated by team semantics and existential second-order logic, we develop a model-theoretic framework for studying second-order objects such as sets and relations. We introduce a notion of abstract elementary team categories that generalizes the standard notion of abstract elementary class, and show that it is an exam...

PXRD characterization of uranium and plutonium peroxide and hydroxide phases of interest for MOx fuel preparation

Paul ESTEVENON · Lucas MULLER · Fatima CHMALI · Christoph HENNIG · y 1 más

In order to develop alternative pathway for the synthesis of uranium and plutonium oxide mixture for MOx fuel preparation and to evaluate the behavior of representative surrogate systems for spent nuclear fuel, several conversion processes are under study. Among them, the hydrothermal processes of uranium and plutonium...

Electronic, magnetic, and structural properties of novel iron oxides

Xiang LI · Georgios APRILIS · Ilya KUPENKO · Cheng QIAN · y 1 más

The proposed experiment focuses on exploring the electronic configurations and magnetic properties of the known novel mixed-valence iron oxides (e.g. Fe5O7, Fe25O32), as well as discovering new novel iron oxides using the Synchrotron Mössbauer Source spectroscopy and Single-Crystal X-ray diffraction up to 200 GPa and 5...

Laccase-induced modification of lignin nanoparticles: Mechanisms and fractional analysis

Danila M. Carvalho · Patricia Figueiredo · Kristiina S. Hilden · Timo Hatanpää · y 4 más

The adjustment of the surface chemistry of lignin nanoparticles (LNPs) can be effectively achieved through laccase-induced biocatalysis. However, the mechanistic and fractional aspects of this process remain largely unknown. This study investigated the reaction mechanisms induced by recombinant Coprinopsis cinereus lac...

Revealing microscopic behaviors in strained infinite-layer nickelate membrane via RIXS with in-situ tunable strain

Jiarui LI · Yonghun LEE · Wei-Sheng LEE · Flora YAKHOU-HARRIS

Exploring infinite-layer nickelate properties is a topic of current interest. Our initial measurements unveiled strain-induced XAS dichroism, indicating significant electronic structure modification. We propose to perform Ni L3-edge RIXS on free-standing, strained nickelate membranes to investigate orbital, magnon, and...
