Photoelectrochemical hydrogen production by Halobacterium halobium
Sediroglu, V; Yucel, M; Gunduz, L; Turker, L; Aydemir, A; Eroğlu, İnci (1996-06-28)
A bio-photoelectrochemical reactor has been designed and constructed in order to understand the biocatalytic effect of Halobacterium halobium on the electrochemical production of hydrogen in salt solution. Photoelectrochemical studies were carried out at 25 degrees C in 20 % NaCl solution containing 0.68 mu M bacteriorhodopsin. The reactor was illuminated by a 1000 W projector lamp which was 50 cm apart.
Photofermentative Hydrogen Production by Agar Immobilized Co-Cultures of Purple Non-Sulfur Bacteria
Koku, Harun; Yücel, Ayşe Meral (2021-05-28)
Purple non-sulfur (PNS) bacteria have the ability to produce biohydrogen via photofermentation. This study focuseson hydrogen production using co-cultures of immobilized PNS bacteria, investigates the possible synergistic effectof their co-cultures, and the advantages of immobilization. Growth, hydrogen production and substrate utilization ofsingle-cultures and, double and triple co-cultures of R. capsulatus hup- (YO3), Rp. palustris (DSM 127) and R.sphaeroides O.U.001 (DSM 5864) were compared using an arti...
Photovoltaic properties of benzotriazole containing alternating donor–acceptor copolymers: Effect of alkyl chain length
Baran, Derya; Balan, Abidin; Stubhan, Tobias; Ameri, Tayebeh; Toppare, Levent Kamil; Brabec, Christoph J. (Elsevier BV, 2012-12)
A series of variable alkyl chain length substituted donor-acceptor (D-A) conjugated polymers with thiophene ring as the donor and benzotriazole moiety as the acceptor has been investigated in bulk heterojunction solar cells. The optical and electrochemical properties showed that the absorption onsets and the energy levels of the copolymers were not affected by alkyl substitution revealing 1.9 eV of optical band gap. The morphologies of the blend film can be fine-tuned by increasing the chain length attached...
Photo-oxidative degradation of abs copolymer
Güzel, Aylin; Tinçer, Teoman; Department of Polymer Science and Technology (2009)
Acrylonitrile-butadiene-styrene (ABS) polymer is one of the most popular copolymer having an elastomeric butadiene phase dispersed in rigid amorphous styrene and semi-crystalline acrylonitrile. Due to double bonds in the polybutadiene phase, ABS copolymers are very sensitive to photo-oxidative degradation. Photo-oxidation of butadiene rubber phase results in the formation of chromorphores and these chromorphores act as initiators in photo-oxidative degradation and after a while ABS starts yellowing. In this...
