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.

Evaluation of van der Waals density functionals for layered materials [PDF]

, 2018
© 2018 American Physical Society. In 2012, Björkman et al. posed the question "Are we van der Waals ready?" [T. Björkman, J. Phys.: Condens. Matter 24, 424218 (2012)JCOMEL0953-898410.1088/0953-8984/24/42/424218] about the ability of ab initio modeling to

Geckos, ceilings and van der Waals

Chimia, 2018
The ability of a gecko to run rapidly across ceilings and up and down vertical walls is a striking example of the application of van der Waals interactions.

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

Advanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Light-emitting diodes by band-structure engineering in van der Waals heterostructures. [PDF]

Nature Materials, 2014
The advent of graphene and related 2D materials has recently led to a new technology: heterostructures based on these atomically thin crystals. The paradigm proved itself extremely versatile and led to rapid demonstration of tunnelling diodes with ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Quantum Oscillations and Chiral Anomaly in a Bi0.96Sb0.04 Single Crystal

Advances in Condensed Matter Physics, 2019
Bi1-xSbx alloys are of special significance in topological insulator research. Here we focus on the Bi0.96Sb0.04 alloy in which the conduction band edge just touches the valence band edge.

Dynamic van der Waals theory [PDF]

Physical Review E, 2007
We present a dynamic van der Waals theory starting with entropy and energy functional with gradient contributions. The resultant hydrodynamic equations contain the stress arising from the density gradient. It provides a general scheme of two-phase hydrodynamics involving the gas-liquid transition in nonuniform temperature.
