(Institute of Electrical and Electronics Engineers Inc., 2021) Solmaz, Ramzan; Hansu, Fevzi
Surface treatment methods are a subject of increasing interest. Barrier discharge systems are one of the most widely used methods in surface treatment recently. In order to obtain a desired surface, the electric field distribution formed in the reactor is very important. In this study, the potential distribution in semiconductor barrier discharge reactors was numerically analyzed using the boundary element method. To evaluate the accuracy of the boundary element method in the SBD reactor, the same conditions were defined and the problem was solved using the finite element method and analytically. SEM images of the surfaces of the semiconductor layers, which are used as barriers and processed in different modes, were examined to examine the effect of the homogeneous plasma formed in the SBD reactor. The SEM images and the results of the numerical methods were evaluated together. The numerical results of the boundary element method were found to be in agreement with the experimental results. The results can be stated that the boundary element method can be used in reactor design. © 2021 IEEE.

(İESS publishing, 20-22 June, 2019/Siirt/Turkey) Solmaz, Ramazan; Hansu, Fevzi; Alisoy, Hafız
Teknolojinin gelişmesine paralel olarak yarıiletken malzemenin kullanıldığı alanlar giderek yaygınlaşmaktadır. Özellikle uzay teknolojisi, savunma sanayi ve tıp alanında kullanılan sistemlerin her koşulda kararlı, verimli ve uzun ömürlü olması istenmektedir. Elektronik teknolojisinin temelini oluşturan yarıiletken malzemelerin kararlılığı değişken kuvvetli elektrik alan ortamında incelenebilir. Bu çalışmada N tipi yarıiletken malzemenin kararlılığını analiz etmek için DBB sisteminde farklı ortam ve farklı frekans değerlerinde uygulamalar gerçekleştirilmiştir. Bu uygulamalar her ortam için rastgele seçilen 50 Hz, 100 Hz, 200 Hz, 350 Hz ve 500 Hz frekanslı gerilim değerlerinde yapılmıştır. Elde edilen deneysel veriler ile gerilim akım eğrileri oluşturularak N tipi yarıiletken malzeme DBB sistemi ile analiz edilmiştir. Sonuçlara göre vakum ortamında delinmeler 0,675 kV-0,855 kV aralığında meydana gelirken, hava ortamında 6 kV-7,05 kV aralığında ve azot ortamında 7,2 kV-7,95 kV aralığında meydana gelmiştir. Uygulamalara ait delinme gerilimleri ve boşalma akım osilasyonları incelendiğinde DBB sisteminde basıncın önemli bir faktör olduğu görülmektedir. İnert olan azot gazı ise sistemin kararlılığını artırmaktadır. N tipi yarıiletken malzemenin özellikleri düşük basınç, düşük gerilim ve düşük frekansta daha belirgin olduğu söylenebilir.

(Elsevier Ltd., 2014-11-04) Hansu, Fevzi
In this study, the effect of Alternating Current and Direct Current Dielectric Barrier Discharge cold plasmas on the catalytic activity of CoeCreB based catalysts reduced from CoCl2$6H2O ? Cr(NO3)3$9H2O is investigated. The catalytic properties of CoeCreB catalysts utilized in hydrogen generation from the hydrolysis of NaBH4 are examined in the plasma mediums depending on various voltages applied to plasmas. The catalysts are produced by AC plasma and DC plasma methods separately. In the presence of plasma-produced catalyst, the hydrolysis reactions complete within shorter time intervals than in the presence of non-plasma produced catalysts. The best chosen AC plasma-produced CoeCreB catalyst completes the hydrolysis reactions in 5 min; while the non-plasma produced catalyst completes the same reactions in 20 min. The hydrolysis reaction of sodium borohydride with CoeCreB catalyst produced in AC plasma media is controlled by zero order reaction whereas the same reaction is controlled by first order reaction in the presence of COeCreB catalyst produced in DC plasma medium. The activation energy carried out in the presence of CoeCreB catalyst produced in AC plasma and DC plasma mediums was found as 16.17 kJ$mol1 and 18 kJ$mol1, respectively.
Effect of Dielectric Barrier Discharges on the Elimination of Some Flue Gases
(IEEE-Inst Electrical Electronics Engineers Inc, 2020) Akdemir, Murat; Hansu, Fevzi
The rapid development of the industry, rapid population growth, and the increase in the number of modern vehicles used lead to excessive energy consumption. For the purpose of meeting this consumption, the majority of energy is produced as a result of the burning of fossil fuels, especially in underdeveloped countries due to the fact that renewable energy sources have not reached the technological maturity yet. In addition, fossil fuels are still used in factories and homes for heating purposes. As a result of the combustion of these fossil fuels, large amounts of toxic gases are emitted into the atmosphere, and these gases have negative effects on the environment and indirectly on living beings. In this study, a new method was proposed to eliminate toxic components of flue gases. No chemical additives or catalysts were used in this study. In the proposed method, the chemical decomposition of SO2, CO, nitrogen oxide (NOX) gases was simultaneously achieved by applying voltages at various frequencies to a specially designed dielectric barrier discharges (DBD) reactor, and in a controlled manner, the conversion of these gases to other various chemical products was carried out. In this study, it was found that a significant part of the gases could be easily separated with the help of DBD plasma without the need for any catalyst or other systems. According to the results, it was observed that the effect of high-frequency plasma charge bombardment was highly effective in the simultaneous decomposition of toxic gas compounds.
Effect of Induction Heating Aided Dielectric Barrier Discharge on the Elimination of SO2, NOX, and CO Gases
(Springer International Publishing Ag, 2020) Akdemir, Murat; Hansu, Fevzi
In recent years, there has been an increasing need for energy, depending on population growth and the rapid development of industry. Consequently, in large power plants, factories, and vehicles, large quantities of toxic gases are emitted into the air as a result of the burning of fossil fuels every year. These gases have negative effects on both human health and the environment. In this study, a new method was proposed for eliminating environmentally hazardous flue gases without the need of any chemical catalyst unlike existing methods. In the proposed method, chemical decomposition of toxic gases was achieved by applying voltages at various frequencies to a specially designed cylindrical and coaxial dielectric barrier discharges (DBD) reactor, and in a controlled manner, the conversion of these gases to other products which could be useful was carried out. In the study, it was found that most of the gases could be separated by DBD plasma, while some of them had to be subjected to a strong preheating process in order to be separated. According to the results, high frequency plasma charge bombardment has been shown to be highly effective in the decomposition of toxic gas compounds when used together with induction heating method.

Siirt Province has various natural and fossil energy sources such as solar, hydropower, biogas, geothermal, and petrol in terms of energy potential, by contrast with other provinces in Turkey. The data collected in Siirt Province indicate that Siirt has a strong potential for solar energy. The average sunshine duration and total solar radiation in Siirt are about 7.5 h-day and 4.3 kWh/m2-day, respectively. In Siirt, there are two hydropower plants with a total installed power of 263 MW. In addition, more than 10 hydroelectric power plants with a total installed capacity of 1094 MW of power generation will be established by means of the planned dam to be installed. Considering the establishment of biogas systems, Siirt has an annual biogas production of 20,000 m3 with around 500,000 small ruminants. Siirt Province is believed to be rich in geothermal care, but there has not been enough research on this topic, yet. And also, petroleum is an important energy source in Siirt Province, lately. As a result, Siirt Province has a rich variety of energy resources, and in case of investment, it would be an energy basin center in the Southeast Anatolia region.
Experimental Analysis of Current Oscillations of Semiconductor Barrier Discharge
(IEEE-Inst Electrical Electronics Engineers Inc, 2020) Solmaz, Ramazan; Hansu, Fevzi
In this study, experimental analysis of current oscillations of semiconductor barrier discharge (SBD) was carried out. In tests, the current oscillations of semiconductor barriers under various strong electric fields in vacuum, air, and nitrogen gas mediums have been investigated. Experiments were carried out by using p- and n-type semiconductor layers, creating single- and double-barrier electrode configurations. In addition, in the study, frequency response of p- and n-type semiconductor layers was investigated in randomly selected 50-, 100-, 200-, 350-, and 500-Hz frequency rates. With the using of experimental data, the voltage-current curves of SBD were created. It was observed that discharge current gives more stable results in Townsend mode. Furthermore, with increasing of test voltage, the discharge passed to the glow mode that contains the formation of unstable current oscillations. When the obtained data were evaluated, it was concluded that medium pressure had a significant effect on the development of SBD at fixed electrode gap. It was seen that current oscillations of semiconductor layers show more stable behavior at low-voltage, low-pressure, and low-frequency values. It has been concluded that electrical breakdown events in semiconductor barriers occur at higher voltage values than the barrier-free system in vacuum medium.
Experimental frequency analysis of p and n-type semiconductor barriers in SBD system
(Pergamon-Elsevier Science Ltd, 2020) Solmaz, Ramazan; Hansu, Fevzi
An experimental study was conducted to analyze the behavior of semiconductor materials in a variable strong electrical field medium, the effect of semiconductor barriers on the formation and development of the discharge, the barrier effect of semiconductor materials and the frequency response of Semiconductor Barrier Discharge (SBD) system. Applications were carried out in vacuum, air and nitrogen medium separately with randomly selected frequency values. It was seen from the first stage results that the barrier effect of the semiconductor layers on the current oscillations is quite striking in the vacuum medium. As the frequency of the applied voltage increases, the barrier effect of the semiconductor layers was seen to reduce. Besides, as the frequency values increase, the discharge current was determined to get more linear. In the second stage, the results have shown that the SBD operated with the AC voltage characterizes the structure of a band-stop filter. The frequency of the voltage applied to the SBD system and the design of the reactor determine the frequency at which the discharge current was suppressed. Knowing these new features of SBD effects on semiconductors, give an important contribution to the design of the semiconductor production industry.

(2024) Arı, İlker; Hansu, Fevzi
The impact of high-frequency voltage/current oscillations on the corona discharge’s ignition and damping in electrical networks were experimentally investigated as part of this study. Internal and external overvoltages caused by short-circuit faults or circuit opening/closing in the generation, transmission and distribution lines cause voltage/current oscillations on the lines at different frequencies. At frequencies of 50, 150, 250, 350, and 500 Hz in different electrode systems such as Sphere-Plane and Needle-Plane, the effects of these oscillations at various frequencies in the networks on the ignition and damping of corona discharges on transmission lines have been investigated. The results showed that the ignition and damping voltages of corona discharges are greatly influenced by high-frequency voltage/current oscillations, and that an increase in the frequency value significantly speeds up the corona discharge’s ignition.

The hydrogen production from NaBH4 hydrolysis with Ni(0) catalyst prepared in dielectric barrier discharge plasma media created by applying a certain amount of voltages (3–5 kV) and plasma applying times (5–15 min) was investigated depending on NaBH4 concentration (3.2–10%) in solutions, NaOH concentration (1.5–10%) in solutions, catalyst amount (5–20 mg), and temperature (20–60°C). Hydrolysis reaction of NaBH4 with Ni(0) prepared in the presence of dielectric barrier discharge plasma is completed in 45-min time intervals with fast hydrogen generation while the Ni(0) produced in a known method led to a slow hydrogen release and hydrolysis is completed in 70-min time intervals. The hydrogen yield of 3.2, 5, and 10% NaBH4 solution with Ni(0) catalyst prepared in the presence of dielectric barrier discharge plasma takes the values of 95.06, 57.42, and 31.78% at the end of 45 min, respectively. The experimental data were fitted to first-order. The activation energy for first-order was found to be 41.76 kJ mol-1.

(Springer, 2023) Avci Hansu, Tuelin; Hansu, Fevzi; Akdemir, Murat
The systems like portable electronic devices, electric vehicles, and uninterrupted power applications demonstrate the necessity of energy storage recently. Thus the interest in supercapacitor technology, which is thought to be an alternative solution to traditional energy storage devices and provides great advantages in terms of preventing environmental pollution, is increasing day by day. In this study, Prunus spinosa seed waste biomass (PS) was converted to supercapacitor active material for the first time through the different activation processes. The surface characterizations of the obtained materials were performed by using Scanning Electron Microscopy with Energy-Dispersive X-Ray (SEM-EDX), BET, X-Ray Diffraction Analysis (XRD) and Fourier-Transform Infrared Spectroscopy (FTIR) analysis methods. Three different supercapacitor cells were designed in the scoops of the study. When activation with KOH was used in addition to carbonization, there was an increase in the surface area and pore volume of the material, and the capacitance value of the electrodes increased from 15.75 F/g to 48.63 F/g at 1.0 A/g. When the pure material activated with H2SO4, the capacitance increased to 39.92 F/g and a high energy density of 7.05 Wh/kg was obtained as the potential operating range of the electrodes increased. As the electrodes were charged or discharged, their coulombic efficiency increased and the PS-H2SO4 electrode presented an excellent coulombic efficiency. It is tought that the created electrodes promise great potential for the energy storage in terms of cost, efficiency, capacity, and stability.

Yaşamın her alanında (uzay teknolojisi, savunma sanayi, tıp uygulamaları gibi) yaygın olarak kullanılan yarıiletken malzemelerin her koşulda doğru çalışması, verimli ve uzun ömürlü olması istenmektedir. Elektronik sistemlerin temelini oluşturan yarıiletken malzemelerin kararlılıklarının, kuvvetli elektrik alanı ortamlarında incelenmesiyle önemli sonuçlara ulaşılabilir. Bir malzemenin kararlılığının belirlenmesi, bilinen yöntemlerin yanı sıra kuvvetli elektrik alanı ortamında meydana getirdiği akım osilasyonları ile ilişkilidir. Dolayısıyla bu çalışmada, DBB sisteminde P tipi yarıiletken bir malzemenin değişken kuvvetli elektrik alan ortamındaki davranışı araştırılmıştır. P tipi yarıiletken malzeme DBB reaktöründeki düşük gerilim elektrotu üzerinde bariyer tabaka olarak kullanılarak deneysel analiz gerçekleştirilmiştir. Deneyler hava ve vakum ortamında, 50 Hz ile 500 Hz frekans değerlerinde gerçekleştirilmiştir. Elde edilen verilere göre P tipi yarıiletken bariyer tabakanın ortamda meydana gelen akım osilasyonları üzerinde önemli bir etkisi olduğu görülmüştür. Bu etki (P=-0,88 bar) vakum ortamında ve düşük boşalma akımı değerlerinde daha belirgin olarak ortaya çıkmıştır. Ayrıca, boşalma akımının analiz açısından, boşalmanın Townsend modunda daha kararlı sonuçlar verdiği görülmüştür. Yüksek akımlı glow modunda kararsız akım osilasyonları gözlemlenmiştir. DBB uygulamalarında (sabit elektrot açıklığında) delinme vakum ortamında yaklaşık 0,6 kV değerinde gerçekleşirken, atmosferik basınçtaki hava ortamında ise 6,075 kV değerinde meydana geldiği görülmüştür.

In this study, the effect of Alternating Current and Direct Current Dielectric Barrier Discharge cold plasmas on the catalytic activity of Co-Cr-B based catalysts reduced from CoCl2 center dot 6H(2)O Cr(NO3)(3)center dot 9H(2)O is investigated. The catalytic properties of Co-Cr-B catalysts utilized in hydrogen generation from the hydrolysis of NaBH4 are examined in the plasma mediums depending on various voltages applied to plasmas. The catalysts are produced by AC plasma and DC plasma methods separately. In the presence of plasma-produced catalyst, the hydrolysis reactions complete within shorter time intervals than in the presence of non-plasma produced catalysts. The best chosen AC plasma-produced Co-Cr-B catalyst completes the hydrolysis reactions in 5 min; while the non-plasma produced catalyst completes the same reactions in 20 min. The hydrolysis reaction of sodium borohydride with Co-Cr-B catalyst produced in AC plasma media is controlled by zero order reaction whereas the same reaction is controlled by first order reaction in the presence of CO-Cr-B catalyst produced in DC plasma medium. The activation energy carried out in the presence of Co-Cr-B catalyst produced in AC plasma and DC plasma mediums was found as 16.17 kJ.mol(-1) and 18 kJ.mol(-1), respectively.
