Impact of sonication time in nanoparticle synthesis on the nutrition and growth of wheat (Triticum aestivum L.) plant
(Elsevier, 2024)Nanotechnology in agricultural applications is promising in improving plant nutrition and yield, pest control, and gene delivery. However, the method to synthesize nanoparticles or nanocomposites (NCs) can play a crucial ... -
Microplastic contamination in some beverages marketed in türkiye: Characteristics, dietary exposure and risk assessment
(Elsevier, 2024)In this study, microplastic contamination in water, natural mineral water and mineral water, sparkling soft drinks, cold tea and some traditional beverages marketed in Türkiye were assessed. Microplastics physically and ... -
Application of phthalocyanine complexes of Cu(II), Co(II), Ni(II), and Zn(II) as catalysts in the transfer hydrogenation of acetophenone and its derivatives
(Elsevier, 2024)In this study, tetra substituted metallophthalocyanines (M: Ni, Zn, Co, and Cu) containing imine and azo groups were synthesized using microwave irradiation. The structures of all complexes have been totally characterized ... -
Evaluation of radioactivity and radiological parameters in soil samples in Isparta, Türkiye
(Elsevier, 2024)In the city centre of Isparta, located in the southwestern part of Türkiye, indoor radon concentrations and gamma dose rate levels were observed above the world and country averages. For this reason, the determination of ... -
The effective polymeric macromolecule as peroxymonosulfate activator as an alternative to metal oxides in the treatment of organic dye pollutants
(Elsevier, 2024)Catalyst efficiency is affected by inhomogeneous catalyst atom placement on the substrate, leading to nano-level aggregation and reduced performance. Research on single-atom catalysts aims to place them at the atomic level ... -
Iron nanoparticles in combination with other conventional Fe sources remediate mercury toxicity-affected plants and soils by nutrient accumulation in bamboo species
(Elsevier, 2024)The issue of mercury (Hg) toxicity has recently been identified as a significant environmental concern, with the potential to impede plant growth in forested and agricultural areas. Conversely, recent reports have indicated ... -
Shape-preserving properties of the limit q-Durrmeyer operator
(Elsevier, 2024)The present work aims to establish the shape-preserving properties of the limit q-Durrmeyer operator, Dq for 0<q<1. It has been proved that the operator is monotonicity- and convexity-preserving. What is more, it maps a ... -
Investigation of radioactivity concentrations and soil-to-plant transfer factors in soil samples taken from different distance zones to the Metsamor nuclear power plant
(Walter de Gruyter, 2024)Monitoring radioactivity around nuclear power plants is important to avoid the risks of radiation. This study provides an overview of the radioactive emission impact on the near surroundings of the Metsamor nuclear power ... -
Molecular diversity of Klebsiella pneumoniae clinical isolates: antimicrobial resistance, virulence, and biofilm formation
(Taylor & Francis Ltd., 2024)One of the mechanisms responsible for antibiotic resistance in Klebsiella pneumoniae is the enzymes produced by the bacteria; another important mechanism is the ability to form biofilm. In this study, antibiotic resistance, ... -
Determination of plant growth promoting properties and bioremediation potentials of Bacillus mycoides Flugge and B. thuringiensis Berliner
