Non-fullerene organic photovoltaics based on thienopyrroledione comprising random copolymers; effect of alkyl chains
Yasa, Mustafa; Yılmaz, Ayşen; Alemdar, Eda; Hacioglu, Serife O.; Çırpan, Ali; Toppare, Levent Kamil (2021-11-01)
Two new random donor-acceptor (D-A) copolymers, signed as P1 and P2, were designed and synthesized. Electrochemical and spectroelectrochemical measurements were performed to investigate absorption, energy levels, electroni...
The effects of dietary calcium tetraborate on the ovalbumin levels and some egg quality traits in laying quails exposed to cadmium
İflazoğlu, Sera; İflazoğlu Mutlu, Seda; Seven, Pınar Tatlı; Yılmaz, Ayşen; Şimşek, Ülkü Gülcihan (2021-05-01)
Cadmium (Cd) is a toxic heavy metal and one of the most important environmental pollutant that is derived from agricultural and industrial sources. Boron (B) is a metalloid that has beneficial physiological effects on th...
Structural, photo, optical and thermal luminescent properties of beta barium metaborate
Yılmaz, Ayşen; Bulur, Enver (2020-07-15)
Barium borate compounds (BaB4O7-beta-BaB2O4) were produced by different synthesis methods, which include solution assisted solid state synthesis method (SAS), microwave assisted solid state synthesis method (MAS) and high ...
Tunable optical properties and DFT calculations of RE3+ codoped LaBO3 phosphors
Yılmaz, Ayşen; Esentürk, Okan (2019-12-01)
In this study, single phase DyxLa1-xBO3, DyxCeyLa1-x-yBO3, DyxEuyLa1-x-yBO3, and TbxCeyLa1-x-yBO3 phosphors were successfully synthesized through the microwave assisted solid state method with urea. Synthesized compounds w...
Phytoplankton biomass, primary production and chemoautotrophic production of the Western Black Sea in April 2003
Ediger, Dilek; Murray, James W.; Yılmaz, Ayşen (2019-10-01)
The multilayered surface waters of the Black Sea contain aerobic, suboxic and anoxic layers that support both photoautotrophic (PP) and chemoautotrophic (ChP) biological production. During the R/V Knorr cruise from 15 to 2...
