Investigation of the effects on rheological and filtration properties of water-based drilling mud of boron minerals: An experimental study
(Pamukkale University, 2019)
The aim of this study is to determine the effect on the rheological and filtration properties of water based drilling fluid of boron minerals. For this purpose, water-based drilling mud was prepared and borax (Na2B4O7.10H2O) ...
Application of polyoxometalate/carbon nitride nanotubes nanocomposite for directly methanol oxidation
(Pamukkale Univ, 2019)
Fuel cell in this study consumes methanol as fuel and they are very important for clean environment and effective energy conversion. Graphitic carbon nitride (g-C3N4) is carbon allotrope among carbon based nanomaterials. ...
Kablosuz algılayıcı ağlarda küme başı kapsama alanının farklı ağ boyutları ve düğüm sayıları altında ağ yaşam süresine etkisi
(Gazi University, 2019)
The problem of energy efficiency due to the limited resources in Wireless Sensor Networks (WSNs) has made cluster-based architectures widespread use in these networks. The studies in literature regarding WSNs aim to make ...
An Investigation of Punching the MWCNTs Doped Composite Plates by Using Different Cutting Profiles
(University of Osijek, 2021)
In this study, glass fiber reinforced composite layers which are with and without additives of 0.1 wt.% multi walled carbon nanotubes (MWCNTs) of epoxy were manufactured by vacuum infusion method. Unlike the conventional ...
Bidirectional DC–DC converter based multilevel battery storage systems for electric vehicle and large-scale grid applications: A critical review considering different topologies, state-of-charge balancing and future trends
(John Wiley and Sons Inc, 2021)
The expanding share of renewable energy sources (RESs) in power generation and rise of electric vehicles (EVs) in transportation industry have increased the significance of energy storage systems (ESSs). Battery is considered ...
Improved Modeling of Microwave Structures Using Performance-Driven Fully-Connected Regression Surrogate
(Institute of Electrical and Electronics Engineers Inc., 2021)
Fast replacement models (or surrogates) have been widely applied in the recent years to accelerate simulation-driven design procedures in microwave engineering. The fundamental reason is a considerable-and often prohibitive-CPU ...
Wideband Microwave Absorber Comprising Metallic Split-Ring Resonators Surrounded With E-Shaped Fractal Metamaterial
(Institute of Electrical and Electronics Engineers Inc., 2021)
A specially designed metallic E-shaped fractal-based perfect metamaterial absorber (PMA) with fairly wideband absorptivity in the K- and Ka-bands of the microwave regime was investigated. The PMA top surface is comprised ...
Pressure leaching of chalcopyrite with oxalic acid and hydrogen peroxide
(Elsevier, 2021)
This study investigated the dissolution behavior of metals from chalcopyrite concentrate in a pressure reactor system in the presence of hydrogen peroxide by oxalic acid leaching. The fact that the compounds formed by ...
Dynamic coefficient-based cluster head election in wireless sensor networks
(Pamukkale Üniversitesi, 2020)
Owing to the fact that the selection of cluster heads has a significant effect on the lifetime of the network, many researches have proposed various cluster head election methodologies for cluster-based WSNs. Although ...
