Mor lahana özütü kullanarak grafen oksitin indirgenmesi ve oksidasyon ile fotokatalitik aktivitesinin incelenmesi
(GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2023)
Grafen ve türevleri pek çok eşsiz sayılabilecek özelliğe sahip, fotokatalitik bozunum ve adsorpsiyon uygulamalarında potansiyeli olan önemli bir malzemelerdir. Grafen oksitin (GO) indirgenerek oksijen içeren fonksiyonel ...
Hydrophobic surface modification and characterization of melamine foam
(TUBİTAK, 2023)
Abstract: Superhydrophobic and oleophilic modification of commercial acoustic melamine foam (MF) was made in this study. The modification was carried out with chitosan (CHI) and silica particles (SiO2 ), by using both a ...
The relationship between neutrophil lymphocyte ratio, platelet lymphocyte ratio, and depression in dialysis patients
(LIPPINCOTT WILLIAMS & WILKINS, 2023)
Chronic kidney disease is a worldwide public health issue with rising incidence, morbidity/mortality, and cost. Depression and chronic renal disease often coexist, and psychological illnesses are associated with poor ...
Thiolated Cellulose: A Dual-Acting Mucoadhesive and Permeation-Enhancing Polymer
(AMER CHEMICAL SOC, 2023)
This study aims to design an anionic, thiolated cellulose derivative and to evaluate its mucoadhesive and permeation-enhancing properties utilizing enoxaparin as a model drug. 2-Mercaptosuccinic acid-modified cellulose ...
The removal of heavy metals from refinery effluents by sulfide precipitation
(BERG FAC TECHNICAL UNIV KOSICE, 2023)
This study investigated the selective precipitation of copper (Cu2+), nickel (Ni2+) and zinc (Zn2+) ions from industrial wastewater by using sodium sulfide (Na2S). The effects of pH, time and free sulfide concentration on ...
A New Approach for Cu and Fe/FexB Production from Chalcopyrite by Molten Salt Electrolysis
(Springer Science and Business Media Deutschland GmbH, 2020)
Abstract: In the present study, copper (Cu) and iron boride (FexB) were produced for the first time through molten salt electrolysis using chalcopyrite (CuFeS2) in an oxide-based borax electrolyte. Molten salt electrolysis ...
Enhancing the thermal performance of a solar air heater by using single-pass semi-flexible foil ducts
(Pergamon-Elsevier Science Ltd, 2020)
This study focused on improving the thermal performance of a solar air heater (SAH) using a single-pass semi-flexible foil duct that can be applied directly as an absorber without requiring any surface modification. In ...
Experimental and numerical analysis of the splay impact on the performance of splayed cross-cut fin heat sink
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021)
In this study, splayed effects on the thermal performance of standard cross-cut heat sink (S-CCHS), fixed-array splayed (FAS-CCHS), and full splayed (FS-CCHS) under natural and forced conditions are studied experimentally ...
Experimental and numerical investigation on the thermal performance of linear LED housings under forced convection
(Pergamon-Elsevier Science Ltd, 2021)
This study aims to experimentally and numerically test the thermal performances of three different linear housings (Model 1-without fin, Model 2-with inner fin, and Model 3-with inner and outer fin) with medium power ...
