A shape memory alloy based on photodiode for optoelectronic applications
(Elsevier Ltd, 2018)
A photodiode was fabricated as a Schottky contact using Cu-Al-Mn shape memory alloy and p-Si substrate. The alloy was characterized by some characterization techniques such as (SEM), XRD and DSC. The electrical and ...
Aflatoxin M 1 in UHT milk consumed in Turkey and first assessment of its bioaccessibility using an in vitro digestion model
(Elsevier, 2012)
Contamination of milk and dairy products with aflatoxin M 1 (AFM 1) continues to receive increased attention because of its potential health hazard to humans. The first aim of this study was to know the occurrence and ...
Frequency effect on electrical and dielectric characteristics of In/Cu 2 ZnSnTe 4 /Si/Ag diode structure
(Springer New York LLC, 2019)
In/Cu 2 ZnSnTe 4 /Si/Ag diode structure was fabricated by sputtering Cu 2 ZnSnTe 4 (CZTTe) thin film layer on the Si layer with In front contact. The frequency dependent room temperature capacitance and conductance ...
Determination of aflatoxins and ochratoxin A in retail cereal products from Turkey by high performance liquid chromatography with fluorescence detection
(Elsevier Ltd, 2012)
In this study, a total of 110 retail cereal products from Turkey were analysed for aflatoxins (AFB1, AFB2, AFG1 and AFG2) and ochratoxin A (OTA). The mycotoxins were determined by liquid–solid extraction, immunoaffinity ...
Aflatoxin M 1 and ochratoxin A in baby formulae in Turkey: Occurrence and safety evaluation
(Elsevier, 2012)
During 2011, 62 samples of baby formulae were checked for aflatoxin M 1 (AFM 1) and ochratoxin A (OTA) by immunoaffinity column (IAC) clean-up and high performance liquid chromatography with fluorescence detection (HPLC-FD). ...
Natural co-occurrence of aflatoxins and ochratoxin A in spices
(Elsevier, 2012)
The present study aims to determine the co-occurrence of aflatoxins (AFs) and ochratoxin A (OTA) in spices marketed in Turkey. During the period from November 2010 to August 2011, 105 samples of spices were checked for ...
Analysis of temperature-dependent transmittance spectra of Zn0.5In0.5Se (ZIS) thin films
(Springer New York LLC, 2019)
Temperature-dependent transmission experiments of ZnInSe thin films deposited by thermal evaporation method were performed in the spectral range of 550–950 nm and in temperature range of 10–300 K. Transmission spectra ...
Incidence and level of aflatoxin contamination in chilli commercialised in Turkey
(Elsevier Ltd, 2013)
During the years 2011–2012, a total of 182 chilli samples were collected from two provinces of Turkey and checked for aflatoxins (AFs). The samples were analysed using immunoaffinity column (IAC) clean-up and high performance ...
Self-assembly of an organocatalyst for the enantioselective synthesis of Michael adducts and α-aminoxy alcohols in a nonpolar medium
(2013)
A proline-thiourea host-guest complex is described as a self-assembled organocatalyst for the enantioselective Michael addition of aldehydes to nitroolefins and for the asymmetric ?-aminoxylation of both aldehydes and ...
Study of asymmetric aldol and Mannich reactions catalyzed by proline-thiourea host-guest complexes in nonpolar solvents
(2013)
A proline-thiourea host-guest complex has been described as a good catalyst for asymmetric reactions such as aldol and Mannich reactions. High stereoselectivities were obtained under optimal conditions. Thiourea was observed ...
