Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Versatile X-ray reflector extension setup for grazing-incidence experiments at SAXS facilities for liquid surface study

Journal of Synchrotron Radiation
Existing beamlines for in situ grazing-incidence small-angle scattering on liquids are either limited in angular range or incompatible with the large sample–detector distance required for submicrometre resolution.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Molecular Exchange in Lipid Nanoparticles via Time-Resolved Small Angle Neutron Scattering

, 2023
The nano-scale dynamics of lipid nanoparticles (LNPs) for drug delivery play a large role in their function. Limited molecular motion is important for avoiding degradation prior to entering cells.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Structural insights into the dynamics and function of the C-terminus of the E. coli RNA chaperone Hfq

, 2011
The hexameric Escherichia coli RNA chaperone Hfq (Hfq(Ec)) is involved in riboregulation of target mRNAs by small trans-encoded RNAs. Hfq proteins of different bacteria comprise an evolutionarily conserved core, whereas the C-terminus is variable in ...

Small-Angle Scattering from Weakly Correlated Nanoscale Mass Fractal Aggregates

Nanomaterials, 2019
Formation of fractal aggregates is generally an undesired effect which may lead to end products with worse properties as compared to those of the individual components, especially in nanocomposite materials.

Small-angle Delbrück scattering [PDF]

Il Nuovo Cimento, 1964
The Bethe-Rohrlich approximation for small angle Delbruck scattering, which is valid for photon energies of some l00MeV, can be easily modified so as to be also applicable at low energies of a few MeV. This allows to calculate the real and imaginary part of the scattering amplitude at low energies and scattering angles not larger than some 10 mrad ...
