Compositionally complex carbides, nitrides, and carbonitrides represent a promising class of ceramics stable under high temperatures, high pressures, and ultra-harsh environmental conditions. However, their structural stability under simultaneous high-pressure and high-temperature conditions remains largely unexplored. [...]

NaY9Si6O26 nanoparticles with varying Pr3+ concentrations were synthesized by an alkaline hydrothermal process, yield-ing agglomerated spherical particles ∼55 nm in diameter with a hexagonal crystal structure. Emission spectra show thatthe intensity of UV 4f¹5d¹→4f² emissions is partially suppressed by efficient nonradiative relaxation, resulting in sharpvisible emissions from intraconfigurational Pr3+ 4f² transitions. [...]

A significant problem associated with additively manufactured components is the development of high residual stresses,which impact their structural integrity and performance. Measuring these residual stresses in components with curvedsurfaces is often challenging. [...]

This study provides a critical assessment of transverse cold rolling as an alternative deformation route forcontrolling anisotropy in UNS S32304 lean duplex stainless steel by correlating microstructural evolutionwith mechanical, corrosion, and tribological responses. Although transverse cold rolling up to 50%thickness reduction did not fully randomize the microstructure or suppress the anisotropy inherited fromprior cold rolling, it revealed distinct section-dependent deformation behavior and pronounced strainhardening. [...]

Advanced low-density (LD) steels of the Fe–Mn–Al–C system are promising for transportation applications due to their combination of high strength, ductility, and reduced density. In these steels, austenite remains the stable matrix; however, aging promotes phase transformations involving ferrite and κ-carbide. [...]

Ternary eutectic V-Si-B alloys are prime contenders for ultra-high-temperature structural applications due to their low densityand excellent mechanical properties. To optimise their performance, understanding real-time phase transformations underthermal exposure is crucial. [...]

Fe(II) containing spin crossover (SCO) complexes can be reversibly switched between a low-spin (S = 0) and a high-spin (S = 2) state. Switching between the two spin states can be performed e.g. [...]

cquisition, analysis, and decision-making frameworks. While such systems have been demonstrated at individual facilities, adapting them to additional instruments remains challenging due to differences in local infrastructure. [...]
