Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Interfacial oxygen vacancies yielding long-lived holes in hematite mesocrystal-based photoanodes

Nature Communications, 2019
The performance of hematite (α-Fe2O3) photoanodes is limited by fast charge recombination. Here, authors develop hematite mesocrystal-based photoanodes with abundant interfacial oxygen vacancies for highly efficient solar water splitting under back ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Elastic scattering of deuterons from 16O in the α-cluster model with dispersion [PDF]

Ядерна фізика та енергетика, 2011
On the basis of the α-cluster model with dispersion, multiple diffraction scattering theory and diffraction model the calculations of d-16O scattering observables at 700 MeV have been performed. The used approach could allow us to describe interaction of

Influence of the Broken Surface Layer on Dynamic Scattering in Crystals with Defects

Успехи физики металлов, 2004
The model of scattering for a crystal with the disturbed surface layer (DSL) and randomly distributed defects (RDD) is proposed and developed within the framework of dynamical theory of the total integrated reflective power in Bragg-diffraction geometry.

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

Advanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

Effect of Collimation on Diffraction Signal-to-Background Ratios at a Neutron Diffractometer

Quantum Beam Science
High diffraction signal-to-background ratios (SBRs), the ratio of diffraction peak integrated intensity over its background intensity, are desirable for a neutron diffractometer to acquire good statistics for diffraction pattern measurements and ...
