Surface science studies of metal hexaborides

open access: yesScience and Technology of Advanced Materials, 2012
Over 30 years of surface science research on metal hexaborides are reviewed. Of this class of compounds, lanthanum hexaboride has been the subject of the majority of the studies because of its outstanding properties as a thermionic emitter.

Metal ceramic wear mechanisms [PDF]

open access: yes, 1990
Sliding wear of metal-on-ceramic, ceramic-on-metal, and ceramic-on-ceramic have been investigated using a tri-pin-on-disc machine. A technique has been developed for thin foil preparation for transmission electron microscopic examination perpendicular ...

Compressive characteristics of metal matrix syntactic foams [PDF]

open access: yes, 2012
The compressive behaviour of eight different metal matrix syntactic foams (MMSFs) are investigated and presented. The results showed that the engineering factors as chemical compositions of the matrix material, the size of the microballoons, the ...

Aromaticity in catalysis: metal ligand cooperation via ligand dearomatization and rearomatization

open access: yes, 2021
Unlike the conventional model of transition metal catalysis, ligands in metal–ligand cooperative (or bifunctional) catalysis are involved in the substrate activations.

A parametric study of metal-to-metal contact flanges with optimised geometry for safe stress and no-leak conditions [PDF]

open access: yes, 2004
This paper presents the results of a parametric study of the behaviour of metal-to-metal contact flanges that have different surface profiles. Using a finite element analysis approach, the important stress values in the flange and bolts and flange ...

Absence of critical thickness for polar skyrmions with breaking the Kittel’s law

open access: yesNature Communications, 2023
The period of polar domain (d) in ferroics was commonly believed to scale with corresponding film thicknesses (h), following the classical Kittel’s law of d ∝ $$\sqrt{h}$$ h .

Long-term field metal extraction by pelargonium:phytoextraction efficiency in relation to plant maturity [PDF]

open access: yes, 2011
The long length of periods required for effective soil remediation via phytoextraction constitutes a weak point that reduces its industrial use. However, these calculated periods are mainly based on short-term and/or hydroponic controlled experiments ...

Modelling of Metal-Coating Delamination Incorporating Variable Environmental Parameters [PDF]

open access: yes, 2014
A mathematical model for metal-coat delamination of degrading metal was developed incorporating multiple variable environmental parameters. Metal-coat delamination not only depends on the electrochemical reactions at metal-coat interface but also on the ...

Research of structural entropy of sheet aluminium alloys depending on annealing temperature

open access: yesMATEC Web of Conferences, 2018
Sheet blanks’ structure uniformity determines their ability to sheet stamping. Level of entropy may represent the characteristic of structural uniformity.
