Enhanced crystallization of GeTe from an Sb2Te3 template
, 2012 Crystalline Sb 2Te 3 templates reduce the crystallization time of the phase change material GeTe by four orders of magnitude to 20 ns. Structural measurements and density functional theory molecular dynamics atomistic modeling show that this reduction is

Structural stability during remelting of foundry binary alloys
Литьë и металлургияA nanostructural mechanism of structural stability during remelting of foundry binary alloys has been developed. This mechanism is determined by the stability of the centers of crystallization of microcrystals of α‑phases and β‑phases.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Journal of Synchrotron Radiation, 2007 Crystal centering is a key step in macromolecular X-ray crystallography experiments. A new method using image-processing and machine-vision techniques allows the centering of small crystals in the X-ray beam. This method positions crystals even when the loop is initially out of the camera's field of view and adapts to the difficulty of the experiment ...

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy
Advanced Engineering Materials, EarlyView.A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation
