Conference Object Cleaner Production Solutions For Abrasive Waterjet Cutting System(Kocaeli Üniversitesi, 2022) Ayturan, Zeynep Cansu; Dursun, ŞükrüWaterjet technology is one of the fastest-growing machining processes used for cutting metal to depths over 100 mm. It is used in a wide range of industries from automotive and aerospace to medical and food industries. The impact of the water alone is enough to machine material, however, with the addition of abrasive, the material removal rate in the process is several orders of magnitude higher. Therefore abrasıve waterjet cuttıng system (AWJC) was developed for better performance. In the AWJC, an abrasive material is used in the cutting process to increase cutting efficiency for harder materials. The abrasive material is mixed with water. Mixing means gradual entrainment of abrasive particles within the water jet and finally, the abrasive water jet comes out of the focusing tube or the nozzle. During the mixing process, the abrasive particles are gradually accelerated due to the transfer of momentum from the water phase to the abrasive phase and when the jet finally leaves the focusing tube, both phases, water and abrasive, are assumed to be at the same velocity. Consumables in this process include water, abrasive, orifice, and mixing tubes. The cutting head is the main part of the machine where cutting occurs. In this study, a company using the AWJC system was visited and environmental problems with wastewater handling, abrasive material sludge, and waste cut materials were detected. To solve these problems, three applicable cleaner production solutions have been offered such as recycling of abrasive material, recycling of water, and good housekeeping applications.Article Konya Gürültü Kirliliği ve Eylem Planlarının Yorumlanması(2019) Dalkılıç, Emre; Dursun, Şükrü; Ayturan, Zeynep Cansuİnsanoğlunun hayatında huzurun değeri hiçbir varlıkla değiştirilemeyecek kadar yüksektir. Ancak dünyamızdaki hızlı nüfus artışı, teknolojik gelişmeler, sanayileşme ve trafikteki araç sayısının artışı gibi birçok faktör pek çok sorunu beraberinde getirmektedir. Gürültü: çevresel kaliteyi, hoş görüntüyü ve insan sağlığını olumsuz yönde etkileyen önemli bir sorundur. Gürültüyü hoşa gitmeyen ses veya var olan doğal sesin kirlenmiş hali olarak tanımlanabilmektedir. Özellikle büyük kentlerimizdeki gürültü, çağımızın hastalığı olan stres başta olmak üzere insan yaşamını ve doğal hayatı etkileyerek, kentlerimizi yaşanmaz hale getirmekte ve toplumsal sorunlar açığa çıkmaktadır. Bu çalışmada Konya’da Konya Büyükşehir Belediyesi tarafından yapılan uzun süreli ölçüm, izleme ve değerlendirme sonucunda oluşturulan eylem planları uygulama çalışmalarının gürültü kirliliği üzerindeki sonuçlarının değerlendirilmesi yapılmıştır. Kentte eğlence mekânları civarındaki gürültünün kontrolünün gerektiği, trafikte yeşil şerit uygulamaları, raylı sistem ve demiryolu hattında yapılan iyileştirmeler değerlendirilmiş, mevcut iyileştirmelerin problemin çözümünde yeterli olmadığı görülmüştür. Eylem planları uygulama mevcut azaltıcı ve önleyici faaliyetlerin kent gürültü kirliliği üzerine olası etkileri değerlendirilmiştir. Eğlence yerleri, trafik, raylı sistemler ve sanayi kaynaklı gürültü kirliliğinin azaltılması ve önlenmesini içeren Gürültü Haritaları ve Maruziyet Analizleri yorumlanmıştır. Bu çalışma sonrasında Çevresel Gürültü Eylem Planı kapsamında; Konya Kent Merkezine (Meram, Karatay, Selçuklu ilçeleri) ait topoğrafik haritalar ile birlikte modellenmesi, her bir gürültü kaynağına ilişkin (Eğlence yerleri, Raylı sistem ve demiryolu, endüstri ve trafikten kaynaklı) gürültü haritaları yorumlanmıştır.Article Citation - WoS: 6Citation - Scopus: 8Modeling and Assessment of PM10 and Atmospheric Metal Pollution in Kayseri Province, Turkey(MDPI, 2023-02-10) Semerci, Mumin; Kunt, Fatma; Karagonen, Ilknur; Yumun, Feray; Akgun, Mehmet; Ayturan, Zeynep CansuAir pollution has numerous detrimental consequences for human health, visibility, climate, materials, plant health, and animal health. A portion of air pollution consists of metals, which are emitted into the environment via the combustion of fossil fuels, industrial activities, and the incineration of metal-containing products. In this work, the particulate matter and particle-related metal pollution from various sources, in the Turkish province of Kayseri, were determined. AERMOD modeling was also used to examine the distribution of PM10 around the Kayseri Organized Industrial Zone (OIZ). Particulate matter (PM10) samples were collected using MCZ dust collecting devices at six monitoring locations mainly affected by residential heating (Hurriyet, Talas, and Kocasinan), industry (OIZ), and traffic (Tramway and Cumhuriyet) during the autumn/winter months and at three monitoring locations mainly affected by residential heating (Kocasinan), industry (OIZ), and traffic (Tramvay) during the spring months. ICP-MS analysis was used to assess the concentrations of the heavy metals (Pb, As, Cd, and Ni) in samples collected over 6 different time periods of 16 days each. During the autumn/winter months, the concentrations of Pb near roadways were found to exceed the Air Quality Assessment and Management Regulation of Turkey (AQAMR) limit value. During all the sampling periods, the Ni and Cd concentrations were below the AQAMR limit values. At the points associated with winter heating, the concentrations exceeded the AQAMR limit value, which may result from coal combustion.Article Cam Yüzeye Ag ve Ni Nano Parçacıkların Tutunmasına Hazırlama Tekniğinin Etkisi(2020-01-31) Dursun, Şükrü; Ayturan, Zeynep CansuNano malzeme üretimi günümüz dünyasının gelişen konularından bir tanesidir. Bu malzemelerin hazırlanması amacıyla kullanılan hidrotermal, ıslak emdirme gibi birçok yöntem bulunmakla birlikte bunlardan en çok tercih edileni sol-jel yöntemidir. Sol-gel yönteminde, bir öncü malzeme uygun bir çözücü içinde çözülür. Belirli bir karışım periyodunun ardından elde edilen sol üretilmek istenilen malzemeye göre işlemden geçirilir. Bu çalışma kapsamında sol-jel yöntemi kullanılarak nano parçacıklar üretilmiş ve cam yüzeye daldırma ile kaplama yöntemi kullanılarak kaplanmıştır. Temel nano malzeme olarak TiO2 içeren sol daha önceden denenmiş bir teknikle hazırlanmıştır. Doplama amacıyla Ag ve Ni içeren başka bir sol daha hazırlanarak karışmaları sağlanmıştır. Bu sol’ün hazırlanması sırasında karışım periyodu, kimyasal ilave sırası, çeşidi, molar oranları ve miktarları gibi parametrelerde değişiklikler yapılarak elde edilen son ürün üzerindeki tutunma yüzdeleri kıyaslanmıştır. Toplamda 8 adet deneme yapılarak cam yüzeye kaplanmıştır. Nano parçacıkların hazırlanmasında kullanılan bu denemelerin sonuçları, enerji yayılımlı X-Işını (EDX) analizlerine göre Ag ve Ni' nin cam yüzeyinde tutunma konsantrasyonlarına bakılarak karşılaştırılmıştır. Bunun yanı sıra ilk 5 deneme için X-ışını kırınım (XRD) analizleri de yaptırılmış ve elde edilen kırınım grafikleri de dikkate alınarak yorumlanmıştır. Çalışma sonucunda denemelerin çoğunluğunda yüksek yüzdelerde tutunma oranları elde edilmiştir. Hazırlama sırasında kullanılan kimyasal ve reaktif sayısının son ürünü ciddi şekilde etkilediği ve kompleks bileşik oluşumuna sebep olabileceği ve yüzeydeki Ag ve Ni tutunmasına en çok etki eden faktörlerin doplanan bileşik yüzdesi, sol içerisine kimyasal ekleme sırası ve sol içerisinde kullanılan kimyasalların molar oranları olduğu tespit edilmiştir.Conference Object Removal of Vocs With Photocatalytic Oxidation Method by Using Doped Tio2 Photocatalyst(Imascon, 2021) Dursun, Şükrü; Ayturan, Zeynep CansuOrganic air pollutants are also known as volatile organic compounds (VOCs). All compounds containing carbon (except for carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate) that are volatile under normal conditions are defined as volatile organic compounds. These compounds may create serious health problems, especially at high dosages. Photocatalytic oxidation is one of the most preferred methods for the removal of VOCs. Of course, it is possible to use photocatalytic oxidation for the removal of both inorganic and organic air pollutants. Studies have shown that more successful results are obtained in the removal of organics. In photocatalytic oxidation hydroxyl radicals and superoxide O2 ions, usually from the cleavage of water, are used to remove air pollutants. The pollutants in the air stream are passed through a semiconductor material exposed to light at a certain humidity. The semiconductor structures used during the photocatalytic oxidation process are selected based on the chemical properties of the photocatalyst and its light absorption capacity. Semiconductors such as TiO2, ZnO, WO3, ZnS and CdS are widely used as photocatalysts. Among these photocatalysts, the most widely used photocatalyst is TiO2. In recent years, the number of studies in the field of photocatalytic oxidation process and development of new photocatalysts has been increasing. Both morphological design (improvements related to the surface area of the catalyst) and electronic modifications (additions to the photocatalyst to improve its charge transport properties) can be applied in order to spread the photocatalyst activity of photocatalysts to wider wavelengths and to reduce the tendency to carry photogenic charges for recombination. In this study, the removal of VOCs with photocatalytic oxidation was investigated with the help of a doped TiO2 photocatalyst.Conference Object Indoor Formaldehyde Emission in Air and Health Impacts(Sage Publication, 2019) Kunt, Fatma; Ayturan, Zeynep Cansu; Dursun, Şükrü; Mankolli, HysenIn this review, formaldehyde emission sources in indoor air and its effects on human health are examined. The most important sources of formaldehyde compound, which has several different varieties, have many different usage areas such as kitchen materials, binders in wooden materials and chemical materials. Nowadays, people spend most of their time in a closed environment. There are 3 kinds of formaldehyde according to usage area. Formaldehyde is polymerized to produce urea formaldehyde, melamine formaldehyde and phenol formaldehyde. These substances are volatile and have harmful effects on indoor air.Article Citation - WoS: 6Citation - Scopus: 8Modeling and Assessment of Pm10 and Atmospheric Metal Pollution in Kayseri Province, Turkey(MDPI, 2023-02-10) Kunt, Fatma; Ayturan, Zeynep Cansu; Yumun, Feray; Karagönen, Ilknur; Semerci, Mumin; Akgün, MehmetAir pollution has numerous detrimental consequences for human health, visibility, climate, materials, plant health, and animal health.

Many European countries use these areas to evaluate the potential contamination risk encountered by the water sources. Germany has described three different water protection zones changing with respect to the types of water sources. Zone I covers the immediate water catchment area within a radius of at least 10 meters. Zone II covers the area of zone I and distance which has been reached by the contaminant up to 50 days. Zone III is more comprehensive than others. It covers the area from Zone II to the very edge of the catchment area of the water source. Determination of priority classes in water sources is important to evaluate the risk of contamination. In this study, priority classes for nitrate leaching, which is dangerous for health if it is found higher levels in a drinking water source, in the water protection zones found in Lechtingen area of Osnabrück, Germany was determined with geographic information system (GIS). The data of nitrate leaching risk, land use, and water protection zones in that area were used to make evaluation about priority classes. As a result, almost 40% percent of the area found as a high priority against nitrate leaching.Conference Object Life Cycle Impact Assessment and Economic Evaluation of Material Cutting Technologies(Univ Porto, Fac Economics, 2022) Öztürk, Elif Göksu; Ayturan, Zeynep CansuAll industries create a certain amount of waste and burden to the environment for manufacturing. As sustainability has gained prominence lately, reducing the environmental impacts in manufacturing has become a must. Life cycle assessment (LCA) is a common method to measure the environmental effects of a manufacturing operation. Material cutting is a manufacturing procedure to obtain the final substance ready to be used regarding its shape and size and is widely used in several industry lines. Certain technologies conduct the cutting process, such as WaterJet and Laser. Evaluating material cutting methods for their environmental outputs is also necessary with the rising awareness of environmentally friendly technologies. Thus, WaterJet and Laser cutting technologies are compared within the scope of LCA in this work. In addition to the LCA, economic evaluation is required to overcome heterogeneities among different industries that use the same technology. Thus, the two technologies are also evaluated regarding their operating costs. To the best of our knowledge, no work compares these two technologies from these perspectives before. Our results showed that the replacement of WaterJet by Laser could lessen the cost of material cutting both environmentally and economically.Article Photocatalytic Reduction of Vocs With Ag/Ni-doped Photocatalyst in Different Temperature and Humidity Environments(MDPI, 2024-01-06) Ayturan, Zeynep Cansu; Dursun, ŞükrüThe photocatalytic oxidation (PCO) process is one of the most preferred, inexpensive, and environmentally friendly methods for VOC removal. It has been determined that this method can remove a wide range of organic pollutants. The removal of benzene and toluene pollutants, two important VOCs commonly encountered in flue gases, has been studied in the scope of this study using the photocatalytic oxidation method under UVA irradiation. For this purpose, the photocatalytic activity of the photocatalyst increased by the metal/metal doping process. Two different metals, a noble metal (Ag) and a transition metal (Ni), were used together for the doping of TiO2 nanoparticles, and the photocatalysts attached to a glass surface were prepared. Four different doping percentages were used for photocatalysts: 0.5%, 1%, 2.5%, and 5%. Several PCO experiments were conducted under different temperatures (120, 150, and 180 degrees C) and humidity conditions (25 and 50%). Photocatalytic oxidation experiments were carried out with artificially produced benzene and toluene gases, and the success of the system was evaluated with respect to removal efficiency calculations. The UVA light source was used for the photocatalytic experiments. The results of the study indicated that the removal efficiencies of toluene were found to be higher than those of benzene, and the most suitable conditions were determined to be 50% humidity and a 120 degrees C environment with the use of a 1% doped photocatalyst.
