In this work, the synthesis of stable silver nanoparticles by the bioreduction method was investigated. Aqueous extracts of the manna of hedysarum plant and the soap-root (Acanthe phylum bracteatum) plant were used as reducing and stabilizing agents, respectively. UV-Vis absorption spectroscopy was used to monitor the quantitative formation of silver nanoparticles. The characteristics of the obtained silver nanoparticles were studied using X-ray diffraction analysis (XRD), energy-dispersive spectroscopy (EDX), and scanning electron microscopy (SEM). The EDX spectrum of the solution containing silver nanoparticles confirmed the presence of an elemental silver signal without any peaks of impurities. The average diameter of the prepared nanoparticles in solution was about 29-68 nm. © TÜBİTAK.

Genotoxicity study of high aspect ratio silver nanowires
Charehsaz, Mohammad; COŞKUN, Sahin; Ünalan, Hüsnü Emrah; Reis, Rengin; Helvacioglu, Sinem; GIRI, Ashok Kumar; Aydin, Ahmet (2017-01-01)
The genotoxicity potential of silver nanowires synthesized via the solution-based polyol method has been investigated. They were found to be non-mutagenic in three Salmonella strains and were not genotoxic in a clastogenicity assay in mice. Residual surfactant was found to have an effect on the toxicological properties of the nanowires by increasing the rate of Ag+ release. Residual surfactant can be easily degraded via a UV treatment.
Microwave assisted synthesis of La-1 (-) xCaxMnO3 (x=0, 0.2 and 0.4): Structural and capacitance properties
Tabari, Taymaz; Singh, Dheerendra; Calisan, Atalay; Ebadi, Mehdi; Tavakkoli, Haman; Caglar, Basar (2017-12-01)
The effect of calcium incorporation on the physicochemical and electrochemical properties of the LaMnO3 (LM) perovskites was studied via several techniques. Moreover, a new microwave assisted method was used to synthesize La(1-x)Ca(,)M(x)nO(3)(LCM) perovskites with various calcium content (x = 0.2 and 0.4). Then, the physicochemical properties of the materials such as crystal structure, particle size, surface area, reducibility and band gap energy were investigated by X-ray Diffraction (XRD), High resolutio...
Highly selective Hg2+ colorimetric sensor using green synthesized and unmodified silver nanoparticles
Farhadi, Khalil; Forough, Mehrdad; Molaei, Rahim; Hajizadeh, Salahaddin; Rafipour, Aysan (2012-01-01)
The reaction between biologically green synthesized silver nanoparticles (Ag NPs) and mercury (II) ions was introduced as a new and high potential calorimetric sensor for the selective recognition and monitoring of mercuric ions in aqueous samples. The green synthesized silver nanoparticles were characterized with surface plasmon resonance (SPR) ultraviolet spectroscopy (UV-vis), SEM and X-ray diffraction analysis (XRD) techniques. The fresh biologically synthesized silver nanoparticles are yellowish-brown ...
Thermal decomposition of polystyrene-b-poly(2-vinylpyridine) coordinated to co nanoparticles
Elmaci, Ayşegül; Hacaloğlu, Jale; Kayran, Ceyhan; Sakellariou, Georgios; Hadjichristidis, Nikos (2009-11-01)
Direct pyrolysis mass spectrometry analyses of polystyrene-block-poly(2-vinylpyridne), PS-b-P2VP, indicated that the thermal degradation of each component occurred independently through the decomposition pathways proposed for the corresponding homopolymers; depolymerization for PS and depolymerization and loss of protonated oligomers for P2VP by a more complex degradation mechanism. On the other hand, upon coordination to cobalt nanoparticles, thermal decomposition of the P2VP blocks was initiated by loss o...
PARTIAL MOLAR PROPERTIES OF MGCL2 IN MGCL2-KCL-CACL2 MELTS
ZHU, J; Karakaya, İshak; THOMPSON, WT (The Electrochemical Society, 1988-01-01)
To further the understanding of electrolytes of value in industrial magnesium electrolysis, the reversible emf for the formation of in fused salts containing and was studied. The data made possible the calculation of thermodynamic solution properties which were used with other data to construct features of the ternary phase diagram. The multiple discrete complex anion (MDCA) model was tested against the thermodynamic findings from the present study. Reasonable agreement was obtained between the experimen...
