Parametric evaluation of electrical discharge coatings on nickel-titanium shape memory alloy in deionized water

Heliyon, 2020
Nickel-titanium shape memory alloy (NiTi) has a unique capacity to restore its initial shape after deformation, which is highly applicable to orthopaedic implantations, especially for the minimization of invasive surgeries.

Minimal resonances in annular non-Euclidean strips [PDF]

, 2010
Differential growth processes play a prominent role in shaping leaves and biological tissues. Using both analytical and numerical calculations, we consider the shapes of closed, elastic strips which have been subjected to an inhomogeneous pattern of ...

Linking Process‐Induced Degradation to Mechanical Property Deterioration in Flax Fiber–Reinforced Bio‐Polymer Matrix Composites

Polymer Composites, EarlyView.
Effect of processing‐induced thermal degradation on the mechanical performance of thermoplastic flax fiber composites. ABSTRACT The drawback of biobased polymer matrix composites (PMCs) is their limited temperature stability, resulting from degradation, which restricts their processability in established composite manufacturing processes requiring ...

Estimation of Excess Ice and Thaw Settlement in Frozen Soil Using Industrial Computed Tomography

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost thaw can induce terrain instabilities and hazards as a result of the loss of excess ice from host sediments. The loss of excess ice threatens the integrity of infrastructure and drives ecosystem changes across northern landscapes. This study tests a nondestructive approach to estimate excess ice and potential thaw settlement using ...

A nested hybridizable discontinuous Galerkin method for computing second-harmonic generation in three-dimensional metallic nanostructures

, 2020
In this paper, we develop a nested hybridizable discontinuous Galerkin (HDG) method to numerically solve the Maxwell's equations coupled with the hydrodynamic model for the conduction-band electrons in metals.

Turbulent Friction in Rough Pipes and the Energy Spectrum of the Phenomenological Theory [PDF]

, 2005
The classical experiments on turbulent friction in rough pipes were performed by J. Nikuradse in the 1930's. Seventy years later, they continue to defy theory.

A First-Principles Study of the Electronic Reconstructions of LaAlO3/SrTiO3 Heterointerfaces and Their Variants

, 2010
We present a first-principles study of the electronic structures and properties of ideal (atomically sharp) LaAlO3/SrTiO3 (001) heterointerfaces and their variants such as a new class of quantum well systems.

Dwelling in a post‐fallout landscape: re‐shaping and sustaining life in a former evacuation zone in Fukushima Habiter après la catastrophe : redonner forme au monde et entretenir la vie dans une ancienne zone évacuée à Fukushima

Journal of the Royal Anthropological Institute, EarlyView.
This article explores the activities of daily life in a village neighbouring the TEPCO nuclear power plant in Fukushima. It argues that one of the potentials of taking a dwelling perspective – a phenomenological approach to living within the ecological and social environments – emerges most compellingly within a polluted landscape.

Quantum point contact due to Fermi-level pinning and doping profiles in semiconductor nanocolumns

, 2006
We show that nanoscale doping profiles inside a nanocolumn in combination with Fermi-level pinning at the surface give rise to the formation of a saddle-point in the potential profile. Consequently, the lateral confinement inside the channel varies along
