We report on the design, verification and performance of MuMax3, an open-source
GPU-accelerated micromagnetic simulation program. This software solves the time-
and space dependent magnetization evolution in nano- to micro scale magnets
using a finite-difference discretization. Its high performance and low memory
requirements allow for large-scale simulations to be performed in limited time
and on... hiện toàn bộ
Graphene sheets that are now routinely obtained by the exfoliation/reduction of
graphite oxide exhibit Raman spectra unlike traditional graphene systems. The
general attributes of the Raman spectra of these ‘wrinkled graphene’ are first
reaffirmed by evaluating the spectra of samples prepared by seven different
exfoliation-reduction methods. These graphene sheets exhibit highly broadened D
and G R... hiện toàn bộ
Though widely used in modelling nano- and micro- structures, Eringen’s
differential model shows some inconsistencies and recent study has demonstrated
its differences between the integral model, which then implies the necessity of
using the latter model. In this paper, an analytical study is taken to analyze
static bending of nonlocal Euler-Bernoulli beams using Eringen’s two-phase
local/nonlocal ... hiện toàn bộ

The present article is about the study of Darcy-Forchheimer flow of Maxwell
nanofluid over a linear stretching surface. Effects like variable thermal
conductivity, activation energy, nonlinear thermal radiation is also
incorporated for the analysis of heat and mass transfer. The governing nonlinear
partial differential equations (PDEs) with convective boundary conditions are
first converted into t... hiện toàn bộ
In this work, we investigate how the film properties of silicon nitride (SiNx)
depend on its deposition conditions when formed by plasma enhanced chemical
vapour deposition (PECVD). The examination is conducted with a Roth & Rau AK400
PECVD reactor, where the varied parameters are deposition temperature, pressure,
gas flow ratio, total gas flow, microwave plasma power and radio-frequency bias

This paper presents a novel dual serial vortex-induced vibration energy
harvesting system for enhanced energy harvesting. It consists of two identical
cantilever-based piezoelectric vortex-induced vibration energy harvesters, which
are successively installed in one plane (which is paralleled with the wind flow
direction) of the wind tunnel. The Lattice Boltzmann method is employed to
predict the s... hiện toàn bộ

Inefficient vascularization hinders the optimal transport of cell nutrients,
oxygen, and drugs to cancer cells in solid tumors. Gradients of these substances
maintain a heterogeneous cell-scale microenvironment through which drugs and
their carriers must travel, significantly limiting optimal drug exposure. In
this study, we integrate intravital microscopy with a mathematical model of
cancer to ev... hiện toàn bộ

The optical and electrical response of metal thin films approaching thicknesses
in the range of the electron mean free path is highly affected by electronic
scattering with the interfaces and defects. Here, we present a theoretical and
experimental study on how thickness and microstructure affect the properties of
Ag thin films. We are able to successfully model the electrical resistivity and
IR o... hiện toàn bộ

This article explores the hydromagnetic steady flow of Jeffrey fluid in the
presence of thermal radiation. The chosen nanofluid model takes into account the
Brownian motion and thermophoresis effects. Flow and heat transfer
characteristics are determined by a stretching surface with flux conditions. The
nonlinear boundary layer flow through partial differential systems is converted
into the ordina... hiện toàn bộ

Preparation and characterization of polymer electrolyte films of PEO+10wt.%
LiPF6 + xwt.% BMIMPF6 (1-butyl-3-methylimidazolium hexafluorophosphate)
containing dopant salt lithium hexafluorophosphate (LiPF6) and ionic liquid
(BMIMPF6) having common anion PF6- are reported. The ionic conductivity of the
polymer electrolyte films has been found to increase with increasing
concentration of BMIMPF6 in ... hiện toàn bộ
