New Insights into the Key Role of Thermal Treatment in V/P/O Catalysts for the Selective Oxidation of -Butane to Maleic Anhydride.

This work explores the thermal treatment of V/P/O catalyst precursors to achieve active and selective catalysts for the oxidation of -butane to maleic anhydride (MA) in a continuous-flow fixed-bed reactor. Vanadyl pyrophosphate (V, VPP), the key catalyst component, is produced together with suitable V vanadium orthophosphate (VOPO) allotropic forms by thermally treating vanadyl hydrogen phosphate hemihydrate (VHP) under various atmospheres and temperature ramps. The characterization conducted by using X-ray diffraction, Raman spectroscopy, and reaction testing allowed the identification of optimal conditions for active and selective catalysts.

Artificial Intelligence as a Potential Catalyst to a More Equitable Cancer Care.

As we enter the era of digital interdependence, artificial intelligence (AI) emerges as a key instrument to transform health care and address disparities and barriers in access to services. This viewpoint explores AI's potential to reduce inequalities in cancer care by improving diagnostic accuracy, optimizing resource allocation, and expanding access to medical care, especially in underserved communities. Despite persistent barriers, such as socioeconomic and geographical disparities, AI can significantly improve health care delivery.
