A simple approach for the fabrication of 3D microelectrodes for impedimetric sensing
(Iop Publishing Ltd, 2015)
In this paper, we present a very simple method to fabricate three-dimensional (3D) microelectrodes integrated with microfluidic devices. We form the electrodes by etching a microwire placed across a microchannel. For precise ...
Neutron Production Cross-Section and Geant4 Calculations of the Structural Fusion Material Co-59 for (alpha,xn) and (gamma,xn) Reactions
(Springer, 2015)
Recent advances in technology and computer sciences give us simplicity to investigate phenomena of nuclear physics. Scientists have improved various nuclear reaction codes such as Talys, Alice/ASH, Cem95, Empire, Geant4 ...
Calculations of Double-Differential Neutron Emission Cross Sections for Be-9 Target Nucleus at 14.2 MeV Neutron Energy
(Springer, 2015)
In this study, we investigated neutron-emission spectra induced by (n,xn) nuclear reactions for the Be-9 structural fusion material at 14.2 MeV neutron energy. We calculated double-differential cross sections () with ...
β-Decay half-lives and nuclear structure of exotic proton-rich waiting point nuclei under rp-process conditions
(Elsevier, 2016)
We investigate even even nuclei in the A similar to 70 mass region within the framework of the proton neutron quasi-particle random phase approximation (pn-QRPA) and the interacting boson model-1 (IBM-1). Our work includes ...
Numerical thickness optimization study of CIGS based solar cells with wxAMPS
(Elsevier Gmbh, 2016)
In this paper, a numerical investigation of the effects of thickness of absorber and buffer layers for a typical CIGS based solar cell was carried out for the first time, employing the wxAMPS software which is a new ...

Assessment of PMMA and polystyrene based microfluidic chips fabricated using CO2 laser machining
(ELSEVIER, 2020)
Laser machining could be an alternative way for the fabrication of microchannels. In this study, laser machining of polymethylmethacrylate (PMMA) and polystyrene (PS) substrates were characterized in detail. A fabrication ...
Alternative screening method for analyzing the water samples through an electrical microfluidics chip with classical microbiological assay comparison of P. aeruginosa
(ELSEVIER, 2020)
Pseudomonas aeruginosa is a pathogenic bacterium in fresh water supplies that creates a risk for public health. Microbiological analysis of drinking water samples is time consuming and requires qualified personnel. Here ...
Definition and detection of simulation noise via imaginary simulated particles in comparison with an electrical microfluidic chip noise
(SPRINGER HEIDELBERG, 2020)
Real problems in science and engineering generally do not have an analytical solution, which invariably leads to the application of numerical methods to analyze the problem. The numerical solutions to the same problem give ...
New empirical formula for calculating (n, p) reaction cross-sections at 14.5 MeV neutrons
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2020)
An empirical formula to calculate the (n, p) reaction cross-sections for 14.5 MeV neutrons for 183 target nuclei in the range 44 <= A <= 212 is presented. Evaluated cross-section data from TENDL nuclear data library were ...
