Power Generation from Concentration Gradient by Reverse Electrodialysis in Anisotropic Nanoporous Anodic Aluminum Oxide Membranes

open access: yesEnergies, 2020
In this study, reverse electrodialysis power generation using an anisotropic anodic aluminum oxide membrane with nanopores of two different pore diameters is proposed and experimentally investigated for the first time.

Formation Mechanism of Rounded SiGe-Etch Front in Isotropic SiGe Plasma Etching for Gate-All-Around FETs

open access: yesIEEE Journal of the Electron Devices Society, 2021
We investigated the formation mechanism of a rounded silicon-germanium (SiGe)-etch front (rounding) in gate-all-around field-effect transistor (GAA-FET) manufacturing.

Minimal geometric deformation decoupling in $$2+1$$ 2+1 dimensional space–times

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We study the minimal geometric deformation decoupling in $$2+1$$ 2+1 dimensional space–times and implement it as a tool for obtaining anisotropic solutions from isotropic geometries.

Compact anisotropic models in general relativity by gravitational decoupling

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Durgapal’s fifth isotropic solution describing spherically symmetric and static matter distribution is extended to an anisotropic scenario. To do so we employ the gravitational decoupling through the minimal geometric deformation scheme.

Instability zones for isotropic and anisotropic multibladed rotor configurations [PDF]

open access: yesMechanism and Machine Theory, 2011
Helicopter ground resonance is an unstable dynamic phenomenon which can lead to the total destruction of the aircraft during take-off or landing phases. The earliest research in this domain was carried out by Coleman and Feingold during the decade of 60s.

Minimal Geometric Deformation: the inverse problem

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
In this paper we show that any static and spherically symmetric anisotropic solution of the Einstein field equations can be thought as a system sourced by certain deformed isotropic system in the context of Minimal Geometric Deformation-decoupling ...

Anisotropic Characteristics of Turbulence Dissipation in Swirling Flow: A Direct Numerical Simulation Study

open access: yesAdvances in Mathematical Physics, 2015
This study investigates the anisotropic characteristics of turbulent energy dissipation rate in a rotating jet flow via direct numerical simulation. The turbulent energy dissipation tensor, including its eigenvalues in the swirling flows with different ...
