Enhanced Ionic Conductivity And Mechanical Strength In Nanocomposite Electrolytes With Nonlinear Polymer Architectures, Recep Bakar, Saeid Darvishi, Erkan Şenses
Turkish Journal of Chemistry
Solvent-free polymer-based electrolytes (SPEs) have gained significant attention to realize safer and flexible lithium-ion batteries. Among all polymers used for preparing SPEs electrolytes, poly(ethylene oxide), a biocompatible and biodegradable polymer, has been the most prevalent one mainly because of its high ionic conductivity in the molten state, the capability for the dissolution of a wide range of different lithium salts as well as its potential for the environmental health and safety. However, linear PEO is highly semicrystalline at room temperature and thus exhibits weak mechanical performance. Addition of nanoparticles enhances the mechanical strength and effectively decreases the crystallization of linear …

Additive-Free Synthesis Of Poly(N-Vinyl Pyrrolidone) And Poly(N-Isopropylacrylamide) Nanogels With Controlled Sizes, Semi̇ha Duygu Süteki̇n, Feyza Kiraç, Olgun Güven
Turkish Journal of Chemistry
An easy method is proposed to prepare poly(vinyl pyrrolidone) (PVP) and poly(N-isopropylacrylamide) (PNiPAAm) nanogels with sizes less than 100 nm. The underlying principle is to prepare dilute polymer solutions in acetone/water mixtures where acetone acts to break tridimensional structure of water hence disrupting the H-bonds bridging polymer coils causing separation and shrinkage in their sizes. Irradiation of these solutions by gamma-rays directly leads to the formation of intramolecular crosslinks within the coils resulting with nanogels with sizes smaller than precursor coils. While the average size of nanogels of PVP irradiated in water only is 236 nm, they were reduced to …

Boron Toxicity Induces Sulfate Transporters At Transcriptional Level In Arabidopsis Thaliana, Ceyhun Kayihan, Emre Aksoy, Su Naz Mutlu
Turkish Journal of Botany
Plants activate glutathione (GSH)-dependent detoxification pathways at biochemical and molecular levels under boron (B) toxicity. Sulfate uptake and transport are necessary for GSH biosynthesis in plants. Therefore, the transcriptional regulation of some sulfate transporters was determined in this study to clarify the importance of these transporters in leaf and root tissues of Arabidopsis thaliana under toxic B conditions. The expression level of SULTR1;3 was dramatically increased in leaf and root tissues under moderate and severe toxic B conditions, suggesting source-to-sink sulfate translocation under B toxicity. Stable expression levels of SULTR2;1, SULTR2;2, and low SULTR3;5 expression might restrict the sulfate movement …

Histochemical And Surface Microstructural Analyses Of Floral Cuticles Provide Evidence For Differential Behaviors In Scent Volatiles Emission In Two Tuberoses (Agave Amica (Medik.) Theide And Govaerts) Cultivars From Asparagaceae, Raktim Bhattacharya, Adinpunya Mitra
Turkish Journal of Botany
Two popular cultivars of tuberose (Agave amica (Medik.) Theide and Govaerts syn. Polianthes tuberosa L.) from the family Asparagaceae, widely cultivated for floricultural purposes are ,'Calcutta Single' (CS) and 'Calcutta Double' (CD). It was evidenced that CS flowers emit intense scent volatiles as compared to CD flowers, while CD flowers retained higher contents of internal pool of scent volatiles than CS flowers. Such contrasting observations between the flowers of two cultivars suggest the role of possible barriers such as cuticles that prevent the emission of scent volatiles. The cuticular structure of both cultivars was studied using different histochemical approaches, …

Turkish Journal of Electrical Engineering and Computer Sciences
In imaging systems, the mixed Poisson-Gaussian noise (MPGN) model can accurately describe the noise present. Total variation (TV) regularization-based methods have been widely utilized for Poisson-Gaussian removal with edge-preserving. However, TV regularization sometimes causes staircase artifacts with piecewise constants. To overcome this issue, we propose a new model in which the regularization term is represented by a combination of total variation and high-order total variation. We study the existence and uniqueness of the minimizer for the considered model. Numerically, the minimization problem can be efficiently solved by the alternating minimization method. Furthermore, we give rigorous convergence analyses of our algorithm. …

Accordingly, there is a need to understand the effects of extreme climate events on ecosystems. Here, we designed a temperature and precipitation manipulation system to simulate extreme climate events of heat, drought, and heavy rainfall. We constructed three soil surface temperature manipulation levels (control, 3 °C, and 6 °C increases) and three precipitation manipulation levels (control, drought, and heavy rainfall) with six replicates, and operated these from day of year …
