Book Part Citation - Scopus: 1Atr1, Boron Exporter in Yeast(Springer Science+Business Media, 2013) Koç, Ahmet; Uluisik, Irem[No abstract available]Book Part Boron Stress Tolerance, Ymr279c and Yor378w(Springer Science+Business Media, 2013) Koç, Ahmet; Uluisik, Irem[No abstract available]Article Design of Sulfur Resistant Cobalt Catalysts by Boron Promotion: Atomic Scale Insights(Sakarya University, 2024) Kızılkaya, A.C.The effect of boron promotion on atomic sulfur formation by hydrogen sulfide dissociation on Co(111), flat surfaces of cobalt nanoparticles, was investigated using Density Functional Theory calculations. The results show that on clean Co(111), hydrogen sulfide dissociation proceeds fast due to low activation barriers, yielding atomic sulfur on the cobalt surfaces. Boron promotion hinders the dissociation of hydrogen sulfide due to increased activation barriers. Furthermore, boron prevents the interaction of sulfur compounds with cobalt surface atoms, as these poisons bind on boron. The findings indicate that boron is an effective promoter that can be used to design sulfur resistant cobalt catalysts. © 2024, Sakarya University.

In order to ensure the sustainable operation of geothermal power plants, it is necessary to recharge geothermal fluids back into the reservoirs. It is worth mentioning that the accidental release of geothermal brines or the accumulation of salts and silica from geothermal power facilities can lead to significant environmental issues. Geothermal fluids brought to the surface for any application must be treated in the most practical and feasible way before discharge to the any receiving body or back to the reservoirs. The objective of this chapter was therefore to study the hydrogeochemical properties of geothermal fluids in different regions and propose some scientific approached for the treatment of spent geothermal fluid prior to its use as an alternative water source, especially in agriculture applications. © 2024 Elsevier Inc.

However, the highest concentrations of naturally occurring aqueous arsenic (As) and boron (B) are found in certain types of geothermal fluids, generally those related to faults and volcanic activity which have caused wide-ranging alteration from argillic type to silica type. The argillic alteration zones are typically enriched in sulfur in volcanic rocks. Also, epithermal systems, which have a high concentration of As in the form of realgar and orpiment along the fracture zones of metamorphic and carbonate aquifers. On the other hand, B can easily rise to the surface by hydrothermal activity or concentrate in residual magma fluids or coexisting liquid and gas phases depending on the geology. The concentration of As and B in geothermal fluids changes in each geothermal field because of the geological properties of the region. For example, the concentration of As in geothermal fluids ranges from 10 μg/L to 50 mg/L in different parts of world whereas the concentration of B ranges from 0.04 to 119 mg/L. This chapter describes the sources and behavior of As and its relationship to elements such as B and chlorine (Cl−) using data from the samples taken from boiling and warm hot springs and geothermal wells in different geothermal fields in Turkey to evaluate their environmental impacts. © Springer Nature Switzerland AG 2021.
