Osmotic energy is a renewable source of energy which is obtained from the physical movement of water molecules between semipermeable membrane due to salinity gradient difference. Pressure retarded osmosis (PRO) is a system which is derived from salinity gradient and uses that osmotic pressure forces to produce energy by the help of turbines at locations such as river mouths where river and sea provides the required salinity gradient. It is a rather new technology which is still in research and development stage. Fresh water from rivers flow into seas surrounding Turkey which have different salinity. The potential of osmotic power at these meeting points of the rivers have not been studied yet. This study assesses the potential of major rivers of Turkey and discusses the utility of the osmotic power. Study areas are selected according to data attainability of salinity gradient, flow rate, temperature of water bodies and membrane water relationships. The yearly change of the parameters needed for production of osmotic power is analysed and potential capacities for PRO facilities are calculated for Turkey. Land area required for membranes for the proposed PRO capacities are also determined and possible locations were selected at the study sites.

Türkiye’nin osmotik enerji potansiyeli
Özyurt Tarakcıoğlu, Gülizar; Korkmaz, Ahmet Berkan (null; 2018-11-30)
Osmotik enerji, tuzluluk değişim farkına bağlı olarak yarı geçirgen zar arasındaki su moleküllerinin fiziksel hareketi sonucu elde edilen yenilenebilir bir enerji kaynağıdır. Osmotik enerji üretimi ise farklı iki konsantrasyona sahip su kaynaklarının özel yarı geçirgen membranlar ile ayrılarak, yoğun çözeltide artan su miktarının sahip olduğu potansiyel enerjinin türbinler aracılığıyla kinetik enerjiye dönüştürülmesiyle meydana gelmektedir. Yenilenebilir bir enerji olan osmotik enerjiye en uygun doğal alanl...
A photoelectrochemical device for water splitting using oligoaniline-crosslinked [Ru(bpy)(2)(bpyCONHArNH(2))](+2) dye/IrO2 nanoparticle array on TiO2 photonic crystal modified electrode
YILDIZ, HÜSEYİN BEKİR; Carbas, Buket Bezgin; Sonmezoglu, Savas; KARAMAN, MUSTAFA; Toppare, Levent Kamil (Elsevier BV, 2016-09-07)
This article describes the construction of photoelectrochemical cell system splitting water into hydrogen and oxygen using UV-vis light under constant applied voltage. Oligoaniline-crosslinked 2-(4-aminobenzyl)malonic acid functionalized IrO2 center dot nH(2)O nanoparticles and visible light absorbing dye, [Ru(bpy)(2)(bpyCONHArNH(2))(+2)] arrays on titanium dioxide (TiO2) photonic crystals modified electrodes were used as photoanode, and nanostructures based on bonding of Pt nanoparticles by using electropo...
ANALYSIS OF THE INTEGRATED INTENSITY OF THE CENTRAL PEAKS CALCULATED AS A FUNCTION OF TEMPERATURE IN THE FERROELECTRIC PHASE OF LITHIUM TANTALATE
Kiraci, Ali; Yurtseven, Hasan Hamit (National Library of Serbia, 2018-01-01)
The integrated intensity of the central peak is calculated as a function of temperature in the ferroelectric phase (T < T-C) of nearly stoichiometric LiTaO3. This calculation is performed using the temperature dependence of the order parameter obtained from the mean field theory at temperatures lower than the transition temperature T-C (T-C = 963 K) of this crystal. The calculated values of the order parameter (squared) are fitted to the integrated intensity of the central peaks as observed from the Raman a...
Efficient energy transfer in cofacial boradiazaindacene (BODIPY) dyes built on a xanthane scaffold as a model for early steps in photosynthesis
Dinç, Tarık; Akkaya, Engin Umut; Department of Biochemistry (2006)
Energy transfer is a natural phenomena that bases of the photosynthesis. In photosynthesis, chlorophyls and auxlary absorbing dyes units absorb solar energy and transfer the energy to the reaction center where other chemical reactions occur. Studies showed that energy transfer depends strongly on distance and rigidy of the structure. Rigid structures that close in space transfer energy nearly %100 efficiency. Supramolecular chemistry tries to mimic nature and miniurize natural phenomence on to molecular sca...
Application of Nanoparticle Antioxidants to Enable Hyperstable Chloroplasts for Solar Energy Harvesting
Boghossian, Ardemis A.; Sen, Fatih; Gibbons, Brenna M.; Sen, Selda; Faltermeier, Sean M.; Giraldo, Juan Pablo; Zhang, Cathy T.; Zhang, Jingqing; Heller, Daniel A.; Strano, Michael S. (Wiley, 2013-07-01)
The chloroplast contains densely stacked arrays of light-harvesting proteins that harness solar energy with theoretical maximum glucose conversion efficiencies approaching 12%. Few studies have explored isolated chloroplasts as a renewable, abundant, and low cost source for solar energy harvesting. One impediment is that photoactive proteins within the chloroplast become photodamaged due to reactive oxygen species (ROS) generation. In vivo, chloroplasts reduce photodegradation by applying a self-repair cycl...
