Adsorption and dissociation of hydrogen molecules on bare and functionalized carbon nanotubes

Dag, S.; Ozturk, Y.; Çıracı, Salim; Yildirim, T. (American Physical Society, 2005)

Interaction between hydrogen molecules and bare as well as functionalized single-wall carbon nanotubes (SWNT) is investigated using first-principles plane wave method. It is found that the binding energy of the H2 physisorbed ...

Characterization, slab-pair modeling and phase analysis of circular fishnet metamaterials

Ozturk, Y.; Yilmaz, A. E.; Colak, E.; Özbay, Ekmel (Elsevier, 2012-06-09)

Planar metamaterials, which have incident to normal plane excitation unlike SRR-type structures and that are easily fabricated in multilayer form, have received great interest in recent years. In this paper, one-dimensional ...

Conversion from constitutive parameters to dispersive transmission line parameters for multi-band metamaterials

Ozturk, Y.; Yilmaz, A. E.; Özbay, Ekmel (Taylor and Francis Ltd., 2016)

In this study, we explain an approach including conversion from constitutive parameters to dispersive transmission line parameters using the double-band DNG (double-negative) properties of the circular type fishnet ...

Resting heart rate estimation using PIR sensors

Kapu, H.; Saraswat, K.; Ozturk, Y.; Çetin, A. Enis (Elsevier B.V., 2017)

In this paper, we describe a non-invasive and non-contact system of estimating resting heart rate (RHR) using a pyroelectric infrared (PIR) sensor. This infrared system monitors and records the chest motion of a subject ...
