Graphene growth from photo-polymerized bi-phenylthiol self-assembled monolayers Open
We present an enhanced methodology for the synthesis of graphene, from photo-polymerized self-assembled monolayers (SAMs) of 1,1ʹ-biphenyl-4-thiol on both electropolished and oxidized copper substrates. The SAMs were subjected to a two-ste…
Microstructure and Mechanical Properties of Laser Additive Manufactured H13 Tool Steel Open
Hot working tool steel (AISI H13) is one of the most common die materials used in casting industries. A die suffers from damage due to friction and wear during its lifetime. Therefore, various methods have been developed for its repair to …
Temperature-Adaptive Ultralubricity of a WS<sub>2</sub>/a-C Nanocomposite Coating: Performance from Room Temperature up to 500 °C Open
This study reports on the ultralubricity of a high-temperature resilient nanocomposite WS2/a-C tribocoating. The coefficient of friction of this coating remains at around 0.02 independently of a thermal treatment up to ∼500 °C, as confirme…
Using X-Ray Scattering to Elucidate the Microstructural Instability of 3D Bicontinuous Nanoporous Metal Scaffolds for Use in an Aperiodic 3D Tricontinuous Conductor–Insulator–Conductor Nanocapacitor Open
The development of three-dimensional aperiodic energy storage devices is in part impeded by the lack of appropriate aperiodic templates that can withstand the thermal conditions required to deposit energy storage materials within their voi…
Depth Profile Analysis of Thin Oxide Layers on Polycrystalline Fe–Cr Open
Surfaces of polycrystalline ferritic Fe–Cr steel with grain sizes of about 13 µ m in diameter were investigated with surface sensitive techniques. Thin oxide layers, with a maximum thickness of about 100 nm, were grown by oxidation in air …
High Entropy Alloys: Ready to Set Sail? Open
Over the past decade, high entropy alloys (HEAs) have transcended the frontiers of material development in terms of their unprecedented structural and functional properties compared to their counterpart conventional alloys. The possibility…
Defect ferromagnetism induced by lower valence cation doping: Li-doped SnO<sub>2</sub> nanoparticles Open
To explore the role of Li in establishing room-temperature ferromagnetism in SnO2, the structural, electronic and magnetic properties of Li-doped SnO2 compounds were studied for different size regimes, from nanoparticles to bulk crystals.
Vapour confinement as a strategy to fabricate metal and bimetallic nanostructures Open
The schematic representation shows the synthesis of different Mg nanostructures using the thermal evaporation method.
In Situ Digital Image Correlation Observations of Laser Forming Open
In this study experimental and modelling methods are used to examine the microstructural and bending responses of laser-formed commercially pure titanium grade 2. The in situ bending angle response is measured for different processing para…
On the Self‐Repair of WS<sub>2</sub>/a‐C Tribocoating Open
This study investigates the self‐healing capacity of a WS 2 /amorphous carbon (a‐C) tribocoating. It is found that prenotches up to 45 µm wide in the WS 2 /a‐C coating surface can be completely healed under the stimulus of sliding operatio…
<i>In Situ</i> High-Temperature EBSD and 3D Phase Field Studies of the Austenite–Ferrite Transformation in a Medium Mn Steel Open
In this research, in situ high-temperature electron backscattered diffraction (EBSD) mapping is applied to record and analyze the migration of the α / γ interfaces during cyclic austenite–ferrite phase transformations in a medium manganese…
Defect ferromagnetism in SnO<sub>2</sub>:Zn<sup>2+</sup> hierarchical nanostructures: correlation between structural, electronic and magnetic properties Open
We report on the ferromagnetism of Sn1−xZnxO2 (x ≤ 0.1) hierarchical nanostructures with various morphologies synthesized by a solvothermal route.
Three-dimensional micron-porous graphene foams for lightweight current collectors of lithium-sulfur batteries Open
This paper reports a three-dimensional (3D) stochastic bicontinuous micron-porous graphene foam (3D-MPGF) developed as lightweight binder-free current collectors for sulfur cathodes of lithium-sulfur batteries. 3D-MPGF is synthesized by a …
Self-healing of a pre-notched WS<sub>2</sub>/a-C coating Open
This letter reports that a pre-notched WS2/a-C tribocoating surface can be fully healed through sliding. The healed notches act as superior lubricant micro-reservoirs affording frictionless responses leading to an ultralow coefficient of f…
