Vacuum-processed polyethylene as a dielectric for low operating voltage organic field effect transistors
Kanbur, Yasin; Irimia-Vladu, Mihai; Glowacki, Eric D.; Voss, Gundula; Baumgartner, Melanie; Schwabegger, Guenther; Leonat, Lucia; Ullah, Mujeeb; Sarica, Hizir; ERTEN ELA, ŞULE; Schwoediauer, Reinhard; Sitter, Helmut; Kucukyavuz, Zuhal; Bauer, Siegfried; Sariciftci, Niyazi Serdar (2012-05-01)
We report on the fabrication and performance of vacuum-processed organic field effect transistors utilizing evaporated low-density polyethylene (LD-PE) as a dielectric layer. With C-60 as the organic semiconductor, we demo...
Preliminary results of the alignment and Hartmann tests of the AZT-22 telescope
Aslan, Z; Bikmaev, IF; Vitrichenko, EA; Gumerov, RI; Dembo, LA; Kamus, SF; Keskin, V; Kiziloglu, U; Pavlinsky, MN; Panteleev, LN; Sakhibullin, NA; Selam, SO; Sunyaev, RA; Khamitov, I; Yaskovich, AL (2001-06-01)
The AZT-22 telescope installed in Turkey (Antalia) was aligned and tested on stars by the Hartmann method. The rms normal deviation of an equivalent optical system is 0.040 +/- 0.016 mum. The circle of confusion is 0.40 +/...
Enzymatically induced mineralization of platelet-rich fibrin
Douglas, Timothy E. L.; Gassling, Volker; Declercq, Heidi A.; Purcz, Nicolai; Pamula, Elzbieta; Haugen, Havard J.; Chasan, Safak; de Mulder, Eric L. W.; Jansen, John A.; Leeuwenburgh, Sander C. G. (Wiley, 2012-05-01)
Membranes of the autologous blood-derived biomaterial platelet-rich fibrin (PRF) were functionalized by incorporation of alkaline phosphatase (ALP), an enzyme involved in mineralization of bone, and subsequently incubated ...
High mobility, low voltage operating C-60 based n-type organic field effect transistors
Schwabegger, G.; Ullah, Mujeeb; Irimia-Vladu, M.; Baumgartner, M.; Kanbur, Y.; Ahmed, R.; Stadler, P.; Bauer, S.; Sariciftci, N. S.; Sitter, H. (Elsevier BV, 2011-10-01)
We report on C-60 based organic field effect transistors (OFETs) that are well optimized for low voltage operation. By replacing commonly used dielectric layers by thin parylene films or by utilizing different organic mate...
Application of the RIMARC Algorithm to a Large Data Set of Action Potentials and Clinical Parameters for Risk Prediction of Atrial Fibrillation
Ravens, Ursula; Katircioglu-Ozturk, Deniz; Wettwer, Erich; Poulet, Claire; Loose, Simone; Knaut, Michael; Oto, Emre; Oto, Ali; GÜVENİR, H. ALTAY (2015-01-27)
Three Dimensional Microfabricated Broadband Patch and Multifunction Reconfigurable Antennae for 60 GHz Applications
Hunerli, H. V.; Mopidevi, H.; Cagatay, E.; Imbert, M.; Romeu, J.; Jofre, L.; Cetiner, B. A.; BIYIKLI, NECMİ (2015-05-17)
In this paper we present two antenna designs capable of covering the IEEE 802.11ad (WiGig) frequency band (57-66 GHz and 59-66 GHz respectively). The work below reports the design, microfabrication and characterization of ...
Antibiotic loaded nanocapsules functionalized with aptamer gates for targeted destruction of pathogens
Kavruk, M.; ÇELİKBIÇAK, ÖMÜR; Ozalp, V. C.; Borsa, B. A.; Hernandez, F. J.; BAYRAMOĞLU, GÜLAY; SALİH, BEKİR; ARICA, MEHMET YAKUP (2015-01-01)
In this study, we designed aptamer-gated nanocapsules for the specific targeting of cargo to bacteria with controlled release of antibiotics based on aptamer-receptor interactions. Aptamer-gates caused a specific decrease ...
Mass and charge distributions in the very asymmetric thermal neutron induced fission of the odd-Z nucleus Am-242m
Tsekhanovich, I; Denschlag, HO; Davi, M; Buyukmumcu, Z; Wostheinrich, M; Gonnenwein, F; Oberstedt, S; Faust, HR (1999-10-25)
Yields of light fission products (A = 68, 70-84, 87, 88, 94, 96, 98, 102 and 106-108), their kinetic energies and nuclear charge distributions (A = 71-84, 87 and 88) in the thermal neutron induced fission of the odd-Z nucl...
