The synthesis, characterization and energy transfer efficiency of a dithienylpyrrole and BODIPY Based Donor-Acceptor System

Atalar, Taner
Algi, Fatih
A dithienylpyrrole-BODIPY based donor-acceptor system with 1,4-phenylene spacer as a model system for energy transfer was designed and synthesized. Absorption and emission spectra have revealed an efficient resonance energy transfer from dithienylpyrrole as donor to BODIPY as acceptor.

GOREKE, Utku; HABİBİABAD, Sahar; Azgın, Kıvanç; Serinağaoğlu Doğrusöz, Yeşim; Beyaz, Mustafa Ilker (2016-02-01)
The design, optimization, and performance characterization of turbine prototypes for the development of a Microelectromechanical Systems spirometer is reported. Four different turbines were designed based on large-scale Savonius turbine architecture. The number of turbine blades was optimized through finite-element simulations to maximize the induced moment and rotational speed at normal breathing flow rates. The turbines were manufactured and tested for their speed performance with respect to input flow ra...
A theoretical and experimental investigation for developing a methodology for co/poly-generation systems: with special emphasis on testing, energy and exergy rating
Özgirgin Bingöl, Ekin; Eralp, O. Cahit; Kılkış, Birol; Department of Mechanical Engineering (2010)
A poly-generation system can be defined as the simultaneous and collocated generation of two or more energy supply types, aimed to maximize the utilization of the thermodynamic potential (efficiency) of the consumed energy resources. A Polygeneration system may involve co-generation (power and heat) or tri-generation (power, heat, and cold) processes and may also be connected to a district energy system. A poly-generation plant reclaims heat in a useful form that would be wasted otherwise in separate electr...

Balkan, N; O'Brien, A; Thoms, AB; Potter, R; Poolton, N; Adams, M; Masum, J; Bek, Alpan; Serpenguzel, A; Aydinli, A; Roberts, J (1998-01-01)
The hot Electron Light Emission and Lasing in Semiconductor Heterostructure devices (HELLISH-1)is novel surface emitter consisting of a GaAs quantum well (QW), within the depletion region, on the n side of Ga1-xAlxAs p-n junction. It utilises hot electron transport parallel to the layers and injection of hot electron hole pairs into the quantum well through a combination of mechanisms including tunnelling, thermionic emission and diffusion of 'lucky' carriers. Super Radiant HELLISH-I is an advanced structur...
The formation and characterization of cyclodextrin functionalized polystyrene nanofibers produced by electrospinning
Uyar, Tamer; Havelund, Rasmus; Hacaloğlu, Jale; Zhou, Xingfei; Besenbacher, Flemming; Kingshott, Peter (2009-05-18)
Polystyrene (PS) nanofibers containing the inclusion complex forming beta-cyclodextrin (β-CD) were successfully produced by electrospinning aimed at developing functional fibrous nanowebs. By optimization of the electrospinning parameters, which included varying the relative concentration of PS and β-CD in the solutions, bead-free fibers were produced. Homogeneous solutions of β-CD and PS in dimethylformamide (DMF) were used with concentrations of PS varying from 10% to 25% (w/v, with respect to DMF), and β...
A New production methodology for vacuum infusion process of advanced composite structures
Poorzeinolabedin, Mohsen; Parnas, Kemal Levend; Department of Mechanical Engineering (2017)
Vacuum Infusion Process (VIP) is one of the Liquid Composite Molding (LCM) methods which are widely used in out-of-autoclave processes especially for the manufacturing of large scale composite parts in aerospace, automotive, wind energy and marine industries. In order to simulate the infusion process, the permeability of preforms is an essential parameter. Absence of any standard is a challenge for the determination of in-plane permeabilities of a preform. The first objective of this study is to develop an ...
