Quantum confinement of Bi2S3 in glass with magnetic behavior
AIP Advances - Tập 3 Số 2 - 2013
Rajendra P. Panmand, Milind V. Kulkarni, Matjaž Valant, Suresh Gosavi, Bharat B. Kale
The novel Bi2S3 quantum dots (QDs) glass nanosystems with unique magnetic properties have been investigated. The monodispersed QDs of size in the range of 3 to 15 nm were grown in the glass matrix. The optical study of these nanosystems clearly demonstrated the size quantization effect resulting in a pronounced band gap variation with QD size. The magnetic properties of the pristine glass and the ... hiện toàn bộ
Electrical characteristics of a low-temperature, atmospheric-pressure helium plasma jet
AIP Advances - Tập 11 Số 1 - 2021
Hajime Sakakita, Tetsuji Shimizu, S. Kiyama
In this work, we precisely measure the electrical properties of a low-temperature atmospheric-pressure helium plasma jet, such as the rf current and voltage, and analyze in detail its characteristics. The results show that the instantaneous plasma current and voltage are nearly in phase, which means that the plasma is purely resistive. The instantaneous plasma power is always active, and the avera... hiện toàn bộ
Influence of heat and mass flux conditions in hydromagnetic flow of Jeffrey nanofluid
AIP Advances - Tập 5 Số 3 - 2015
F. M. Abbasi, Sabir Ali Shehzad, Tasawar Hayat, A. Alsaedi, Mustafa Ali Obid
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
Effect of magnetic-field orientation on dual-peak phenomenon of magnetoelectric coupling in Ni/PZT/Terfenol-D composites
AIP Advances - Tập 9 Số 4 - 2019
Longfei Niu, Yang Shi, Yuanwen Gao
Magnetoelectric (ME) effect in a Ni/PZT/Terfenol-D composite cantilever was tested under three different magnetic loading modes. The frequency-dependent ME effect and dual-peak phenomenon were observed in the experiment. The influence of orientations of magnetic fields on the dual-peak phenomenon of ME coupling was investigated. Magnetic field distribution inside the ME composite structure was sim... hiện toàn bộ
Darcy-Forchheimer flow of Maxwell nanofluid flow with nonlinear thermal radiation and activation energy
AIP Advances - Tập 8 Số 3 - 2018
Tanveer Sajid, Muhammad Sagheer, Shafqat Hussain, Muhammad Bilal
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
Fe2O3 nanowires for thermoelectric nitrogen dioxide gas sensor
AIP Advances - Tập 8 Số 12 - 2018
Jin Yang Lin, A. J. Zhang, S. H. Huang
A thermoelectric nitrogen dioxide gas sensor developed based on Fe2O3 nanowires is capable of outputting DC voltages of tens of millivolts, which facilitates signal amplification and processing. In this paper, the Fe2O3 nanowires were synthesized in a horizontal electrical furnace under air pressure at 600°C for 8 h. SEM and XRD techniques as well as gas sensing performance of prepared sensors tow... hiện toàn bộ
Numerical simulation of two dimensional sine-Gordon solitons using modified cubic B-spline differential quadrature method
AIP Advances - Tập 5 Số 1 - 2015
H. S. Shukla, Mohammad Tamsir, Vineet K. Srivastava
In this paper, a modified cubic B-spline differential quadrature method (MCB-DQM) is employed for the numerical simulation of two-space dimensional nonlinear sine-Gordon equation with appropriate initial and boundary conditions. The modified cubic B-spline works as a basis function in the differential quadrature method to compute the weighting coefficients. Accordingly, two dimensional sine-Gordon... hiện toàn bộ
RDTM solution of Caputo time fractional-order hyperbolic telegraph equation
AIP Advances - Tập 3 Số 3 - 2013
Vineet K. Srivastava, Mukesh Kumar Awasthi, Mohammad Tamsir
In this study, a mathematical model has been developed for the second order hyperbolic one-dimensional time fractional Telegraph equation (TFTE). The fractional derivative has been described in the Caputo sense. The governing equations have been solved by a recent reliable semi-analytic method known as the reduced differential transformation method (RDTM). The method is a powerful mathematical tec... hiện toàn bộ
The flexoelectric effect associated size dependent pyroelectricity in solid dielectrics
AIP Advances - Tập 5 Số 9 - 2015
Gang Bai, Zhiguo Liu, Qiyun Xie, Yunli Guo, Wei Li, Xiaobing Yan
A phenomenological thermodynamic theory is used to investigate the effect of strain gradient on the pyroelectric effect in centrosymmetric dielectric solids. Direct pyroelectricity can exist as external mechanical stress is applied to non-pyroelectric dielectrics with shapes such as truncated pyramids, due to elastic strain gradient induced flexoelectric polarization. Effective pyroelectric coeffi... hiện toàn bộ
MoS2 nanotube field effect transistors
AIP Advances - Tập 4 Số 9 - 2014
Martin Strojnik, Andrej Kovič, A. Mrzel, Jože Buh, Jure Strle, D. Mihailovič
We report on electric field effects on electron transport in multi-walled MoS2 nanotubes (NTs), fabricated using a two-step synthesis method from Mo6SxI9-x nanowire bundle precursors. Transport properties were measured on 20 single nanotube field effect transistor (FET) devices, and compared with MoS2 layered crystal devices prepared using identical fabrication techniques. The NTs exhibited mobili... hiện toàn bộ
