Organic nitrogen in rain and aerosol in the eastern Mediterranean atmosphere: An association with atmospheric dust
Mace, KA; Kubilay, N; Duce, RA (2003-05-31)
From March through early May of 2000, rain and bulk aerosol samples were collected at a coastal site on the eastern Mediterranean Sea at Erdemli, Turkey, and analyzed for nitrogen (N) species, including nitrate (NO3-), nitrite (NO2-), ammonium (NH4+), water-soluble organic N, urea, and dissolved free amino acids. Other ions were also analyzed, including Ca2+, Mg2+, K+, Na+, Cl-, and SO42-. Water-soluble organic N was found to contribute similar to17% and similar to26% of the total water-soluble N in rain an...
Organic/metal-organic photosensitizers for dye-sensitized solar cells (DSSC): Recent developments, new trends, and future perceptions
Yahya, Mohamed; Bouzıanı, Asmae; OCAK, CEMİL; SEFEROĞLU, ZEYNEL; Sillanpää, Mika (2021-08-01)
Humankind is currently heavily reliant on fossil fuel for its energy supply. However, fossil fuels are a nonrenewable source. It requires hundreds of millions of years for fossil fuels to develop inside the earth, and with our daily rate of consumption, we will run out of fuel unless we find an alternative source. Solar energy has gained much attention as a solution for the current energy deficit since it converts light energy directly to electrical energy. Dye-sensitized solar cells deliver a cheaper and d...
Organic acid profile of Turkish white grapes and grape juices
Soyer, Yeşim; Karadeniz, F (Elsevier BV, 2003-10-01)
Organic acid compositions of 11 different white grape cultivars and grape juices were determined by high-pressure liquid chromatography (HPLC). The ranges of acid concentrations found in grapes were as follows: citric, 30-164 mg/l; tartaric, 4.98-7.48 g/l and malic, 1.43-3.40 g/l. Also the ranges of acid concentrations found in grape juices were as follows: citric, 31-181 mg/l, tartaric, 4.07-4.92 g/l and malic, 1.36-3.47 g/l. Tartaric acid was the major acid in every grape variety analyzed. Grape juices ha...
Biological treatment and nanofiltration of denim textile wastewater for reuse
ŞAHİNKAYA, Erkan; UZAL, Nigmet; Yetiş, Ülkü; Dilek, Filiz Bengü (2008-05-30)
This study aims at coupling of activated sludge treatment with nanofiltration to improve denim textile wastewater quality to reuse criteria. In the activated sludge reactor, the COD removal efficiency was quite high as it was 91 +/- 2% and 84 +/- 4% on the basis of total and soluble feed COD, respectively. The color removal efficiency was 75 +/- 10%, and around 50-70% of removed color was adsorbed on biomass or precipitated within the reactor. The high conductivity of the wastewater, as high as 8 mS/cm, did...
Organic/Organic Heterointerface Engineering to Boost Carrier Injection in OLEDs
Fathollahi, Mohammadreza; Ameri, Mohsen; Mohajerani, Ezeddin; Mehrparvar, Ebrahim; Babaei, Mohammadrasoul (2017-02-01)
We investigate dynamic formation of nanosheet charge accumulations by heterointerface engineering in double injection layer (DIL) based organic light emitting diodes (OLEDs). Our experimental results show that the device performance is considerably improved for the DIL device as the result of heterointerface injection layer (HIIL) formation, in comparison to reference devices, namely, the current density is doubled and even quadrupled and the turn-on voltage is favorably halved, to 3.7 V, which is promising...
