The combination of advantages of using zeolites and gold nanoparticles were aimed to be used for the first time to improve the characteristic properties of ion selective field-effect transistor (ISFET)-based creatinine biosensors. The biosensors with covalently cross-linked creatinine deiminase using glutaraldehyde (GA) were used as a control group, and the effect of different types of zeolites on biosensor responses was investigated in detail by using silicalite, zeolite beta (BEA), nano-sized zeolite beta (Nano BEA) and zeolite BEA including gold nanoparticle (BEA-Gold). The presence of gold nanoparticles was investigated by ICP, STEM-EDX and XPS analysis. The chosen zeolite types allowed investigating the effect of aluminium in the zeolite framework, particle size and the presence of gold nanoparticles in the zeolitic framework.

Applications of ions produced by low intensity repetitive laser pulses for implantation into semiconductor materials Wolowski, J.; Badziak, J.; Czarnecka, A.; Parys, P.; Pisarek, M.; Rosinski, M.; Turan, Raşit; Yerci, Selçuk (2008-01-01) This work reports experiment concerning specific applications of implantation of laser-produced ions for production of semiconductor nanocrystals. The investigation was carried out in the IPPLM within the EC STREP 'SEMINANO' project. A repetitive pulse laser system of parameters: energy up to 0.8 J in a 3.5 ns-pulse, wavelength of 1.06 mu m, repetition rate of up to 10 Hz, has been employed in these investigations. The characterisation of laser-produced ions was performed with the use of 'time-of-flight' io...
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 ...
Induction thermal plasma synthesis of Mg2Ni nanoparticles Aktekin, Burak; ÇAKMAK, GÜLHAN; Öztürk, Tayfur (2014-06-15) A study was carried out into possibility of thermal plasma synthesis of Mg2Ni nanoparticles. Both prealloyed powders and elemental powders were used as precursors in an inductively coupled thermal plasma incorporating two injection probes located axially in the reactor one from the top and the other from the bottom. The study has shown that the use of prealloyed Mg2Ni as precursor leads to its disintegration in the plasma condensing into separate phases and therefore was not suitable for the synthesis of Mg...
Photovoltaic Properties of Poly(Triphenylamine-Thiazolo[5,4-d] Thiazole) Copolymer Dye in Bulk-Hetorojunction Organic Solar Cells Olgun, Ugursoy; Gulfen, Mustafa; HIZALAN, Gonul; Çırpan, Ali; Toppare, Levent Kamil (2017-04-01) In this study, the photovoltaic properties of poly(triphenylamine-thiazolo[5,4-d]thiazole) alternating copolymer dye in bulk heterojunction polymer solar cells were examined. The copolymer is a red colored dye material with high thermal stability, good solubility and low-band gap energy. The band gap energy of the polymer was determined as 1.36 eV. The conductivity of the polymer thin film was measured as 1.5x10(-5) S/cm. The polymer solar cells were fabricated using the different ratios of the blends of th...
Multicomponent ion exchange on zeolite 4A Kadaifci, Bijen; Yücel, Hayrettin; Department of Chemical Engineering (2011) In this study binary and ternary ion exchange on Zeolite NaA using silver and cadmium ions were investigated. Ion exchange were conducted at constant temperature (25oC) and normality (0.1N) in a batch system for both binary and ternary experiments. Zeolite weights were varied between 0.1 and 1 g for binary experiments. Thermodynamic analysis of binary ion exchange between Cd2+-Na+ and Ag+-Na+ were examined and thermodynamic equilibrium constant and Gibbs free energy were calculated. Thermodynamic equilibriu...
