Broadband one way propagation via dielectric waveguides with unequal effective index
(Institute of Electrical and Electronics Engineers Inc., 2014)
We present an efficient approach for broad band one way propagation of light by parallel and unequal dielectric waveguides leading different effective phase shifts. Three dimensional numerical simulations show that 30% ...
Wide bandwidth absorption in the MWIR region using a thin and simple metamaterial absorber
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of ...
Bacterial cellulose nanofibers for efficient removal of Hg2+ from aqueous solutions
(Wiley Blackwell, 2018)
The removal of mercury from wastewater is gaining much attention because of being one of the common heavy metal pollutants found in water source affecting human health and environment. Dye affinity chromatography is a ...
Low velocity impact response of glass fiber reinforced aluminium foam sandwich
(European Conference on Composite Materials, ECCM, 2012)
The aim of this study was the analysis of the bending and the low - velocity impact response of aluminium foam sandwich reinforced by the outer skins made of glass fiber reinforced epoxy matrix and the results were compared ...
Elastoplastic stress analysis of functionally graded disc under internal pressure-complas XII
(2013)
The study deals with elastoplastic stress analysis of a hollow disk made of functionally graded materials (FGMs) subjected to an internal pressure. The material properties of disc are assumed to vary radially according to ...
Design of sma based actuators used in robotics
(2013)
This work introduces to Shape Memory Alloy (SMA) using in Robotics as actuators. We investigated a quadruped platform actuated by SMAs which act with variable elasticity. SMAs ought to prove necessary forces for all gaits. ...
Effect of different resistant starch sources and wheat bran on dietary fibre content and in vitro glycaemic index values of cookies
(Academic Press, 2019)
Cross-linked starches produced in lab-scale from corn and wheat starches with TDF contents of 80.4% and 83.6% were used in cookie formulation to obtain high fibre and low glycaemic index (GI) cookies. Different resistant ...
Synthesis and characterization of silicon carbide powders converted from metakaolin-based geopolymer
(Blackwell Publishing Inc., 2016)
Silicon carbide (SiC) ceramic powders were synthesized by carbothermal reduction in specific geopolymers containing carbon nanopowders. Geopolymers containing carbon and having a composition M2O·Al2O3·4.5SiO2·12H2O+18C, ...
Structural, electronic, and electrochemical analyses of sputter-coated Pt and Pt–Co/GCE electrodes with ultra-low metal loadings for PEM fuel cell applications
(Springer Netherlands, 2017)
In this study, unsupported platinum and platinum–cobalt ultra-thin catalyst layers with varying metal loadings were prepared by a sequential magnetron sputtering technique. The deposited catalyst layers were characterized ...
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Kluwer Academic Publishers, 2014)
This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ...
