Optimizing Polyamide Thin-Film Composite Desalination Membranes: Simple And Performance-Effective Modification By Zwitterionic Monohydroxyl Monomer, Selda Erkoç İlter

Turkish Journal of Chemistry

A synthesized zwitterionic monohydroxyl monomer (ZHM) was used as an additive to incorporate zwitterionic sulfobetaine groups into the polyamide (PA) active layers of thin-film composite membranes. Incorporation of ZHM into the PA active layers was achieved through interfacial polymerization, involving the introduction of ZHM and m-phenylenediamine (MPD) into the aqueous phase, and the addition of trimesoyl chloride (TMC) to the hexane phase. The surfaces of the resulting reverse osmosis (RO) membranes were subjected to characterization through water contact angle (WCA) and field emission scanning electron microscopy (FESEM) analyses. The successful incorporation of ZHM into the active PA layers was confirmed …

Turkish Journal of Chemistry

Conducting polymers exhibit interesting dielectric properties due to their unique conjugated π-electron backbone. The objective of this study was to examine the dielectric properties of nanocomposites containing a conducting nanohybrid (NH) as a filler. Polyaniline was grafted onto sepiolite by in situ emulsion graft polymerization to synthesize a conducting NH. This NH was blended with poly(vinyl chloride) (PVC) using a melt blending technique. Nanocomposites with variable amounts of nanofiller were prepared and characterized. Fourier-transform infrared (FT-IR) spectra of the NH composites show strong interactions between their individual components. The addition of the nanofiller into PVC increased its thermomechanical properties. Dielectric …

Selective Extraction Of Scandium From Other Rare Earth Elements Using A Hydrophobic Protic Ionic Liquid Composed Of Decanoic Acid And Toa, Pius Dore Ola, Reo Nishioka, Yoshiro Tahara, Michiaki Matsumoto

Turkish Journal of Chemistry

Rare earth elements (REEs) are increasingly being used in advanced materials, but their extraction remains a major challenge. This is primarily due to their nearly identical ionic radii and similarity in chemical and physical properties. Therefore, this study aims to explore the use of a hydrophobic protic ionic liquid (PIL) composed of decanoic acid and trioctylamine (TOA) to selectively extract scandium (Sc) from other REEs using acid or salt as the extraction medium. In the acidic medium, the extraction efficiency of all tested REEs was inversely proportional to the acid concentration. Meanwhile, the extraction percentage of Sc was significantly higher …

Turkish Journal of Veterinary & Animal Sciences

In this study, the relationship between the Growth Differentiation Factor-9 (GDF9) gene polymorphism and birth weight, as well as weights on days 30, 60, 90, was investigated in Akkaraman lambs, one of the indigenous sheep breeds of Türkiye. For this purpose, a total of 314 lambs were genotyped by PCR-RFLP method for the single nucleotide polymorphism (SNP) c.260G>A in the GDF9 gene. While GG and GA genotypes were observed in the studied breed, the AA genotype was not observed. The results showed that Akkaraman lambs were in Hardy–Weinberg (H–W) equilibrium for the GDF9-c.260G>A polymorphism (p < 0.05). In this study, a significant association was observed between GDF9-HhaI polymorphism and 30th day weight and 60th day weight in Akkaraman lambs. When the animals were analyzed according to birth type, it was observed that this factor was associated with birth weight, as well as weights on days 30, 60, and 90. It is suggested that the c.260G>A coded SNP …


Work Extracting And Second Law-Like Inequalities From Non-Extensive Small Systems With Feedback, Mehdi Mirzaee, Saman Amiri Aug 2025

Work Extracting And Second Law-Like Inequalities From Non-Extensive Small Systems With Feedback, Mehdi Mirzaee, Saman Amiri

Turkish Journal of Physics

The Gibbs-Boltzmann entropy effectively characterizes systems with a significant reliance on initial conditions. Nonetheless, the majority of materials generally exhibit behavior that is independent of their initial conditions. Conversely, Tsallis entropy—a nonextensive entropy that underpins nonextensive statistical mechanics—provides a comprehensive framework for modeling systems that engage with their environment. In this study, we derive the Tsallis formulation of the Clausius inequality in a quantum context and establish an upper limit for the work that can be extracted from a small system within the framework of nonextensive quantum statistical mechanics. Furthermore, by utilizing a principle from quantum information theory—which posits that …


Implications Of Mexican Hat-Like Band Structure On Thermoelectric Properties, Muhammad Hilal, Oğuz Gülseren Aug 2025

Implications Of Mexican Hat-Like Band Structure On Thermoelectric Properties, Muhammad Hilal, Oğuz Gülseren

Turkish Journal of Physics

Electronic band structure of low dimensional materials significantly impacts their thermoelectric performance. A Mexican hat-like band structure, characterized by a ring-shaped extremum in momentum space, offers distinct advantages due to its singularity in the density of states at the band edge and its ability to enhance energy-dependent transport. This work investigates a two-dimensional tight-binding model hamiltonian that incorporates both nearest-neighbor (t1) and next-nearest-neighbor (t2) hopping. The ratio of the hopping amplitudes, ξ = t2/t1, serves as a tunable parameter that modulates the shape and depth of the Mexican hat dispersion. We use an analytical expression for the energy band of …

Optimization And Model Averaging Of Histogram-Based Place Cell Firing Rate Maps Using The Point Process Framework, Murat Okatan Jul 2025

Optimization And Model Averaging Of Histogram-Based Place Cell Firing Rate Maps Using The Point Process Framework, Murat Okatan

Turkish Journal of Electrical Engineering and Computer Sciences

The firing rate of hippocampal place cells depends on the spatial position of the organism in an environment. This position dependence is often quantified by constructing spike-in-location and time-in-location histograms, the ratio of which yields a firing rate map. The purpose of this study is to present a new method for optimizing the spatial resolution of histogram-based firing rate maps. It is pointed out that histogram-based firing rate maps are conditional intensity functions of inhomogeneous Poisson process models of neural spike trains, and, as such, they can be optimized through model selection within the point process framework. The point process …
