Performance-Enhanced Non-Enzymatic Glucose Sensor Based on Graphene-Heterostructure
Mahmoud A. Sakr, Karim Elgammal, Anna Delin +1
This study proposes a novel design of glucose sensor with enhanced selectivity and sensitivity by using graphene Schottky diodes, which is composed of Graphene (G)/Platinum Oxide (…
Skyrmion lifetimes in ultrathin films
Stephan von Malottki, Pavel F. Bessarab, Soumyajyoti Haldar +2
We show that thermal stability of magnetic skyrmions can be strongly affected by entropic effects. The lifetimes of isolated skyrmions in atomic Pd/Fe bilayers on Ir(111) and on Rh…
Turbulence modulation by finite-size spherical particles in Newtonian and viscoelastic fluids
Sagar Zade, Fredrik Lundell, Luca Brandt
We experimentally investigate the influence of finite-size spherical particles in turbulent flows of a Newtonian and a drag reducing viscoelastic fluid at varying particle volume f…
Buoyant finite-size particles in turbulent duct flow
Sagar Zade, Walter Fornari, Fredrik Lundell +1
Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) have been employed to investigate the dynamics of finite-size spherical particles, slightly heavier than th…
Turbulent channel flow of finite-size spherical particles with viscous hyper-elastic walls
M. N. Ardekani, M. E. Rosti, L. Brandt
We study single-phase and particulate turbulent channel flows, bounded by two incompressible hyper-elastic walls. Different wall elasticities are considered with and without a 10%…
Hemorheology in dilute, semi-dilute and dense suspensions of red blood cells
Naoki Takeishi, Marco E. Rosti, Yohsuke Imai +2
We present a numerical analysis of the rheology of a suspension of red blood cells (RBCs) in a wall-bounded shear flow. The flow is assumed as almost inertialess. The suspension of…
