MOS-C Based Electronically Tuneable Current/Voltage-Mode Third Order Quadrature Oscillator and Biquadratic Filter Realization
(Kauno Technologijos Universitetas, 2021)
This paper introduces a new electronically tuneable third order quadrature oscillator and biquadratic filter with MOS-C realization using all grounded passive components. Voltage-mode second order low-pass, high-pass, ...
Non-fullerene organic photovoltaics based on thienopyrroledione comprising random copolymers; effect of alkyl chains
(Elsevier, 2021)
Two new random donor-acceptor (D-A) copolymers, signed as P1 and P2, were designed and synthesized. Electrochemical and spectroelectrochemical measurements were performed to investigate absorption, energy levels, electronic ...
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, ...
Numerical study of a swirl gas turbine combustor for turbulent air and oxy-combustion of ammonia/kerosene fuels
(Elsevier, 2021)
Since ammonia has a carbon-free substance and involves hydrogen atoms per volume unit, many scientists think it could be used as an alternative fuel instead of natural gas or kerosene-based fuels in gas turbine combustors. ...
Quantitative Analysis of Stakeholder Perspective on the University-Industry-Government Collaboration in İzmir, Turkey
(Springer, 2021)
Industry 4.0 necessitates the transformation of businesses towards the use of digital technologies and become more competitive in a global market. The collaboration of businesses and academic institutions is a fundamental ...
The brominated flame retardants TBECH and DPTE alter prostate growth, histology and gene expression patterns in the mouse
(Elsevier, 2021)
The brominated flame retardants (BFRs), 1,2-dibromo-4-(1,2 dibromoethyl)cyclohexane (TBECH) and 2,3-dibromopropyl-2,4,6-tribromophenyl ether (DPTE) bind to the androgen receptor (AR). in vitro bioassays have shown that ...
Reviewing Flexibility in Housing with Free Sorting Method
(Yıldız Technical University Faculty of Architecture, 2021)
It is seen that houses which fail to satisfy user needs - even though they are newly built- are modified/transformed by users. As these modifications and transformations sometimes require significant physical procedures ...
Tuning thermoelectric properties of Bi2Ca2Co2Oy through K doping and laser floating zone processing
(Elsevier, 2021)
In the present study, thermoelectric Bi2Ca2-xKxCo2Oy ceramic materials (x = 0.0, 0.05, 0.075, 0.10, and 0.125) in different forms (called bulk, as-grown and annealed fibers) have been manufactured via a classical solid-state ...
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 ...
A thermally stable and polarization insensitive square-shaped water metamaterial with ultra-broadband absorption
(Elsevier, 2021)
In this paper, square-shaped water metamaterial is reported, which can be used as a perfect absorber for ultra-broadband absorption in the microwave frequency range. Computer Simulation Technology (CST) software was used ...
