Altering Electronic and Optical Properties of Novel Benzothiadiazole Comprising Homopolymers via π Bridges
(IOP Publishing, 2021)
Four novel benzo[c][1,2,5]thiadiazole comprising monomers namely 5-fluoro-6-((2-octyldodecyl)oxy)-4,7-di(thiophen-2-yl)benzo[c][1,2,5]thiadiazole (TBTT), 5-fluoro-4,7-bis(4-hexylthiophen-2-yl)-6-((2-octyldodecyl)oxy)benz ...
Sensitivity analysis of laminated composite plates with different orientations in low to high order modes
(IOP Publishing, 2021)
Laminated composite plates are utilized due to their high strength/weight ratios. Since such structures are light and have less stiffness, their natural frequencies are lower than usual isotropic structures. Therefore, ...
Synthesis and characterization of nanoparticles reinforced epoxy based advanced radar absorbing composites
(Springer, 2021)
In this study, the structural and magnetic properties of NixCo1-xFe2O4 (0.0 <= x <= 1.0) and ZnO nanoparticles synthesized by the sol-gel method were investigated. The microwave property of the composite structures produced ...
The effect of nanoparticle additive on surface milling in glass fiber reinforced composite structures
(SAGE Publications, 2021)
In this study, the effect of adding nanosize additive to glass fiber reinforced composite plates on mechanical properties and surface milling was investigated. In the light of the investigations, with the addition of MWCNTs ...
An ultrathin and dual band metamaterial perfect absorber based on ZnSe for the polarization-independent in terahertz range
(Elsevier, 2021)
In this work, a new metamaterial design is proposed to yield an ultra-thin and dual band metamaterials perfect absorber (MPA) to be operated in the frequency range from 15 to 35 THz. The proposed structure is consisted of ...
A monopole microwave-assisted electrochemical sensor for the detection of liquid chemicals
(S.C. Virtual Company of Phisics S.R.L, 2021)
In this paper, a new sensor structure is presented based on a printed circuit board (PCB) monopole antenna with operating frequency of f=2 GHz. Numerical investigation was performed in order to determine the ethanol alcohol ...
Microstructure, some mechanical properties and tribocorrosion wear behavior of boronized Al0.07Co1.26Cr1.80Fe1.42Mn1.35Ni1.10 high entropy alloy
(Elsevier, 2021)
High-entropy alloys (HEAs) with face-centered cubic (FCC) structures exhibit high toughness and corrosion resistance, but their average strengths and relatively low wear resistance can limit their engineering ap-plications. ...
Natural hydroxyapatite obtained from pufferfish teeth for potential dental application
(Hanyang University, 2021)
Hydroxyapatite and associated calcium phosphate ceramic materials are commonly applied as implant resources because of their close resemblance in structure with natural bone. In the present study, the elemental composition ...
Polarization-based surface enhanced Raman scattering from single colloidal DNA decorated with 3 nm silicon nanoparticles
(American Institute of Physics Inc., 2021)
Surface enhanced Raman scattering (SERS), in which sample molecules are placed in the proximity of conducting nanostructures, subjects the molecules to intense electron oscillation (plasmon) field. The intense field, ...
Pack-Boriding of Monel 400: Microstructural Characterization and Boriding Kinetics
(Korean Institute of Metals and Materials, 2021)
Monel 400 was pack-borided in the temperature range of 1173-1273 K for exposure times of 2-6 h. The boride layers produced on the surface of the alloy were examined by scanning electron microscopy and phase identification ...
