Crystalline ZnO offers an excellent host matrix to create a dilute magnetic semiconductor (DMS) owing to its facile Zn-atom substitution with the transition metal dopant atom. The exchange interactions between the spin of the dopant atoms and the carriers in the ZnO matrix results in the room-temperature ferromagnetic order in the entire lattice. In this work, we report on the enhanced solubility (doping) of Fe atoms in ZnO matrix. Zn1-x FexO DMS nanoparticles were synthesized with different doping concentrations (x = 0.01, 0.05, 0.20, 0.22, and 0.25) via a modified version of co-precipitation method, in which the precursors’ solution was heated at 60 ℃ during the stirring process. Only the wurtzite phase was obtained for all Zn1-x FexO samples in X-ray diffraction, and no secondary phase was observed, which supports the idea of an enhanced solubility limit of Fe doping up to 25%. A systematic broadening of the Raman characteristic peak at 525 cm−1 associated with Fe substitution across the entire range of doping accompanied with the suppression of ZnO peak at 371cm−1 and 435 cm−1, supporting the enhanced doping effect further. The bandgap exhibited a systematic trend — it first increased from 3.13 eV for undoped to 3.23 for x = 0.1 and dropped to the value of 2.94 for the highest concentration (x = 0.25) with few in band transitions for high doping. VSM results showed magnetic behavior for all the doped samples at room temperature.

Liquid properties of Pd-Ni alloys
Kart, SO; Tomak, Mehmet; Uludogan, M; Cagin, T (2004-07-01)
Liquid properties of Pd-Ni metal alloys are computed by molecular dynamics (MD) simulation with the use of quantum SuttonChen potential (Q-SC) model. The thermodynamical, structural, and transport properties of the alloy are investigated. The melting temperatures for Pd-Ni system are predicted. The temperature and concentration dependence of diffusion coefficient and viscosity are reported. The transferability of the potential is tested by simulating the liquid state. The values of melting point are in exce...

An amperometric biosensor was designed using immobilizing alcohol oxidase in conducting polymer of poly 4-(2,5-di(thiophen-2-yl)-1H-pyrrole-1-1) benzenamine matrix via crosslinking with glutaraldehyde on platinum electrode. An electrochemical technique was used for the polymerization of conducting polymer onto the electrode. Carbon nanotubes and gold nanoparticles were also added to the biosensing system to observe the effects of nanoparticles. The proposed biosensor was characterized and optimized in terms...

A new tetrakis 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl) substituted nickel phthalocyanine (NiPc-SNS) was synthesized and characterized by elemental analysis, Fourier Transform Infrared (FT-IR), and UV-vis spectroscopies. The electrochemical polymerization of this newly synthesized NiPc-SNS was performed in dichloromethane (DCM)/tetrabutylammonium perchlorate (TBAP) solvent/electrolyte couple. An insoluble film was deposited on the electrode surface, both during repetitive cycling and constant potential electr...
Pyrolysis mass spectrometry analysis of polycarbonate/poly(methyl methacrylate)/poly(vinyl acetate) ternary blends
Uyar, Tamer; Rusa, Cristian C.; Tonelli, Alan E.; Hacaloğlu, Jale (2007-01-01)
Direct insertion probe pyrolysis mass spectrometry (DIP-MS) analyses of polycarbonate/poly(methyl methacrylate)/poly(vinyl acetate), (PC/PMMA/PVAc), ternary blends have been performed. The PC/PMMA/PVAc ternary blends were obtained by coalescing from their common gamma-cyclodextrin-inclusion compounds (CD-ICs), through the removal of the gamma-CD, host (coalesced blend), and by a co-precipitation method (physical blend). The coalesced ternary blend showed different thermal behaviors compared to the co-precip...
Effect of silver encapsulation on the local structure of titanosilicate ETS-10
GALIOGLU, Sezin; ZAHMAKIRAN, Mehmet; Kalay, Yunus Eren; Özkar, Saim; Akata, Burcu (2012-09-01)
Silver(0) nanoparticles stabilized by titanosilicate (ETS-10) framework were synthesized by following a simple two step procedure involving the incorporation of silver(I) (Ag+) ions into ETS-10 matrix via ion-exchange with extra framework Na+ and K+ cations followed by their reduction with sodium borohydride (NaBH4) in aqueous medium all at room temperature. Silver(0) nanoparticles dispersed in the ETS-10 matrix were collected as gray powders and characterized by using advanced analytical methods including ...
