63. Development and commissioning of a capillary flow cell for quasi-simultaneous in situ/operando XAS-XRD catalysis studies: Oxidative de-ligation of atomically-precise supported metal oxo-cluster catalysts as a showcase study

Oral

Registering dynamic changes in short- and long-range atomic ordering of solid catalysts under operando conditions, i.e. during catalytic action under relevant operation settings, is essential for the rational development of this important class of functional materials. Synchrotron radiation X-ray absorption (XAS) and diffraction (XRD) techniques allow such studies, the challenge being to mimic...

5. Structure matters: asymmetric CO ignition at square and triangular Rh steps

Oral

Tracking the active site of catalytic metallic nanoparticles in mandatory for tailoring new catalysts and promote a clean and green environment. The activity of each of the facets of the nanoparticle will differ depending on the orientation and coordination of surface atoms [1], yet isolating their individual activity is typically challenging. Within this context, curved crystals possess...

69. Recent progress on synchrotron radiation based operando characterization of battery materials at Alba Synchrotron

Ashley P. Black (Instituto de Ciencia de Materiales de Barcelona)

Oral

Operando synchrotron radiation-based characterization techniques applied to energy storage materials are becoming a widespread characterization tool as they allow for non-destructive probing of materials with various depth sensitivities through spectroscopy, scattering, and imaging techniques. Moreover, they allow for faster acquisition rates, variable penetration depths, higher spectral or...

50. Effect of Cd pollution on Se-biofortified wheat: competing interactions and influence on the selenium species stored in the grains

Oral

Selenium (Se) plays a vital role in regulating the metabolic activities in humans as it is needed for the thyroid gland functioning, effective immune response, fertility, and detoxification of free radicals.[1] Unfortunately, the Se content in foods depends on the Se present in the cultivation soil which can be very low in certain regions to satisfy the dietary requirements. Indeed, around a...
