Synthesis, characterization and comparative studies on the photophysical and photochemical properties of metal-free and zinc(II) phthalocyanines with phenyloxyacetic acid functionalities
(Pergamon-Elsevier Science Ltd, 2011)
The synthesis and characterization of new peripherally and non-peripherally tetra-substituted metal-free and zinc(II) phthalocyanines with 2-, 3- and 4-phenyloxyacetic acid functionalities are described for the first time ...
Modelling of dynamic cutting force coefficients and chatter stability dependent on shear angle oscillation
(Springer London Ltd, 2017)
Productivity of high-speed turning operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting tool ...
Metal (Al, Fe, Mn and Cu) distributions and origins of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments of the Marmara Sea and the coast of Istanbul, Turkey
(Pergamon-Elsevier Science Ltd, 2011)
In this study, total metal (Al, Fe, Mn and Cu) and PAHs analyses have been done in the surface sediments. Sediment samples have been collected from seven parts of the Marmara Sea and the coast of Istanbul during 2009. Total ...
CFD modelling and experimental validation of cell performance in a 3-D planar SOFC
(Pergamon-Elsevier Science Ltd, 2019)
Fuel cells can be used to provide power for most electrical or electronic devices designed for operation from batteries or from conventional utility power sources. In this study, a three dimensional Computational Fluid ...
A comparative analysis study of alternative energy sources for automobiles
(Pergamon-Elsevier Science Ltd, 2015)
Depletion of oil resources and some environmental factors have been pushing automobile makers and the scientific communities to study on the use of alternative energy sources in automobiles. In this respect, some energy ...
Characterizations of special time-like curves in Lorentzian plane L-2
(World Scientific Publ Co Pte Ltd, 2017)
In this paper, we first obtain the differential equation characterizing position vector of time-like curve in Lorentzian plane L-2. Then we study the special curves such as Smarandache curves, circular indicatrices, and ...
Investigation of carbonates in the Sutter's Mill meteorite grains with hyperspectral infrared imaging micro-spectroscopy
(Pergamon-Elsevier Science Ltd, 2018)
Synchrotron-based high spatial resolution hyperspectral infrared imaging technique provides thousands of infrared spectra with high resolution, thus allowing us to acquire detailed spatial maps of chemical molecular ...
Preparation of RF sputtered AZO/Au thin film hydrogen peroxide sensitive electrode for utilization as a biosensor
(Springer, 2014)
In this study, hydrogen peroxide (H2O2) sensitive Al doped ZO(AZO)/Au thin film electrode has been developed for the utilization as a biosensor. A preferred c-axis oriented AZO/Au thin film was deposited on quartz substrate ...
Special functions in transferring of energy; a specific case: Airy function
(Sila Science, 2012)
Analysis of transferring of transient signals along time-harmonic waveguide modes consists of two main parts. The first one is a modal basis problem. The second one is a modal amplitude problem. Surplus of energy could be ...
A research on SCADA application by the help of OPC server for the water tank filling system
(Academic Journals, 2010)
This study deals with the data exchange issues based on object linking and embedding for process control (OPC) server in industrial automation systems. OPC server is a software developed to solve the driver device problem, ...
