Various metastable ice phases and their complicated transition pathwayshave been found by pressurization at low temperatures at which slowkinetics and high metastability are easily achieved. By contrast, suchdiversity is less expected at room or elevated temperatures. [...]

The development of advanced materials with optimum structural and mechanical propertiesrequires a detailed control of their microstructures, textures and crystalline defects. Differenttechniques can be used for the characterization of those microstructures and defects, but it istheir combination that could result in an exhaustive understanding of the microstructural andorientational developments on these materials.X-Ray Diffraction (XRD) can be employed to obtain a “global” characterization ofmicrostructure and texture, since the presence of defects in the sample produces shift andbroadening of diffraction peaks.

The microstructural evolution and carbon partitioning mechanism involved during one-step quenching and partitioning (Q&P) process with shorter partitioning time (from 10 to 60 s) were investigated in a CMnSiAl steel. The final microstructure consisted of carbon depleted tempered or partitioned lath martensite, fresh lath martensite, blocky retained austenite (of 5 to 7.8 vol.%) along the prior austenite grain boundaries (PAGB’s) and inter-lath austenite films.

Scintillation detectors are essential tools in high-energy physics, medical imaging, and security, due their efficiency in converting ionizing radiation into visible light. Lead-based inorganic perovskites, particularly 3D CsPbBr3, have emerged as promising next-generation scintillators due to their high photon attenuation and fast emission properties. [...]

We have investigated the humidity-responsive structure of polymer–surfactant multilayer nanofilms composed of a hydrophilic maleic acid polymer and an amphoteric amine oxide surfactant (C12-AO). Neutron reflectometry (NR) revealed the presence of a smooth thin film comprising several surfactant bilayers intercalated with the polymer. [...]
