Aydemir, Önder; Ergün, Ebru (Elsevier Science Bv, 2019)

Background: the input signals of electroencephalography (EEG) based brain computer interfaces (BCI) are extensively acquired from scalp with a multi-channel system. However, multi-channel signals might contain redundant ...

The role of intrinsic atomic defects in a Janus MoSSe/XN (X = Al, Ga) heterostructure: a first principles study

Yelgel, Övgü Ceyda (Institute for Condensed Matter Physics, 2023)

The interactions between different layers in van der Waals heterostructures have a significant impact on the electronic and optical characteristics. By utilizing the intrinsic dipole moment of Janus transition metal ...

Schottky diode fabrication via cold substrate evaporated ag on sol-gel derived ZnO ultra-thin films for semiconductor devices

Keskenler, Eyüp Fahri; Haıdar, M. (S.C. Virtual Company of Phisics S.R.L, 2020)

ZnO thin films were grown on glass and SnO2 substrate by using Sol-gel method with a simple, low cost-temperature and high controlled away. ZnO thin films were contacted with Ag in two different temperatures at 200K (cold ...

Self-Q-switched and multicolor operation of a Tm:LuAG laser

Beyatlı, Ersen; Kaya, Fatma; Bilici, Hatice (Optical Soc Amer, 2020)

Single and multiple doping effects of silicon-boron and fluorine on ZnO thin films deposited with sol-gel spin coating technique

Turgut, Güven; Keskenler, Eyüp Fahri (Springer, 2014)

Undoped, Si and B single doped, Si-B co-doped and Si-B-F triple doped ZnO thin films were grown by sol-gel spin coating method. Effects of these doping elements on microstructural, morphological and optical properties were ...

Solar energy sector under the influence of Covid-19 pandemic: A critical review

Eroğlu, Hasan; Cüce, Erdem (2021)

Different controversies arise when the world is dealing with the Covid-19 outbreak and fast solutions are produced in the field of health. However, the impact of Covid-19 on some critical sectors is perspicuous. One of the ...

Solution and performance analysis of subset sum problem with a new metaheuristic approach

Keskenler, Mustafa Furkan; Keskenler, Eyüp Fahri (TUBITAK, 2020)

Subset sum problem was solved with two different metaheuristic approaches in the study. After these approaches, which are simulated annealing and genetic algorithms, a hybrid model of two methods was created and better ...

Solution blown nanofibrous air filters modified with glass microparticles

Polat, Yusuf; Çalışır, Mehmet; Güngör, Melike; Sağırlı, Merve N.; Atakan, Raziye; Akgül, Yasin; Kılıç, Ali (Sage Publications Inc, 2021)

High-pressure drop and lower dust holding capacity reduce the performance of nanofibrous air filters. For that reason, this study was carried out to form filters with high-quality factor and high dust holding capacity, ...
