Specimens of pure and Pb-doped high-T-c superconductors Bi2Sr2Ca2Cu3O10 (BSCCO) were irradiated with gamma-rays up to an integrated dose of about 225 MR. The variations of normal state resistance, transition temperature, critical current and lattice parameters with gamma-irradiation were studied. The normal state resistance increases with increase of gamma-dose at zero applied magnetic field, whereas the transition temperature and the critical current decrease with the same gamma-dose. The intensities of the X-ray diffraction peaks of the pure samples decrease with increase of gamma-dose without significant change of diffraction angles or peak widths. BSCCO superconductor is found to be quite sensitive to gamma irradiation but drastic lattice expansion do not occur up to 225 MR. (C) 1997 Academic Press Limited.

EFFECT OF ELECTRON AND GAMMA-RAY IRRADIATION ON THE CHEMICAL-COMPOSITION AND ATOMIC DISTRIBUTION OF COPPER-BASED AND IRON-BASED ALLOYS
BINNATOV, KG; RODIONOV, YL; Mehrabov, Amdulla; ALIZADE, II (1990-01-01)
This paper reports that the oxygen, hydrogen, carbon, nitrogen, and sulfur contents of steels and alloys can vary as a result of irradiation by electrons and gamma rays at comparatively low temperatures. As this takes place, the materials can be either saturated with these elements, or these elements can be removed from the irradiated materials, depending on the irradiation medium. Transformations are initiated as a result of radiation-stimulated oxygenation of copper-iron, iron-manganese, and iron-nickel a...
Effect of hydrogen ion-exchange capacity on activity of resin catalysts in tert-amyl-ethyl-ether synthesis
Boz, N; Doğu, Timur; Murtezaoglu, K; Dogu, G (Elsevier BV, 2004-08-10)
Activities of ion-exchange resin catalysts, having different hydrogen exchange capacities ranging between 5.1 and 1.3 meq H+/g, on the etherification reactions of 2M1B (2-methyl-1-butene) and 2M2B (2-methyl-2-butene) with ethanol were experimentally tested in a fixed bed reactor. These catalysts were prepared by the heat treatment of Amberlyst-15 catalysts at 220 degreesC at different durations of time and also by the synthesis of sulfonated styrene divinyl benzene cross-linked resins. Activity of these cat...
Effect of boron implantation on the electrical and photoelectrical properties of e-beam deposited Ag-In-Se thin films
ÇOLAKOĞLU, TAHİR; Parlak, Mehmet; KULAKCI, MUSTAFA; Turan, Raşit (2008-06-07)
In this study, e-beam evaporated Ag-In-Se (AIS) thin films were doped by the implantation of boron (B) ions at 75 keV with a dose of 1 x 10(15) ions cm(-2) and a subsequent annealing process was applied to the doped AIS films at different temperatures under nitrogen atmosphere. The effects of implantation and annealing on the electrical and photoelectrical properties of AIS thin films were investigated through temperature dependent conductivity, spectral photoresponse and photoconductivity measurements unde...
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 ...
Effect of biogenic substrate concentration on 4-chlorophenol degradation kinetics in sequencing batch reactors with instantaneous feed
ŞAHİNKAYA, Erkan; Dilek, Filiz Bengü (Elsevier BV, 2006-09-01)
Two sequencing batch reactors (SBRs) instantaneously fed with 200mg/l 4-chlorophenol (4-CP) were operated at different feed peptone concentrations to investigate the effect of biogenic substrate (peptone) concentrations on reactor performance, yield coefficient (Y) and 4-CP degradation kinetics. One of the reactors was operated at 10 days of sludge retention time (SRT) and the other was operated at 20 days of SRT. High chemical oxygen demand (COD) removal efficiencies (90-95%) and complete 4-CP removals (de...
