Hydrophobic surface modification and characterization of melamine foam

Okutan, Merve; Boran, Filiz; Ergün, Ayça; Kanca, Yusuf; Özkahraman, Bengi; Deligöz, Hüseyin (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 ...

Hydrophobicity of galena with ovalbumin and dithiophosphinate in relation to its potential response

Güler, Taki; Deniz, Vedat; Polat, Ercan (Polish Mineral Engineering Society, 2018)

This study was performed to elucidate the role of ovalbumin (OVA) on the hydrophobicity and potential response of galena in the presence of dithiophosphinate (DTPI). OVA was tested as environmentally friendly depressing ...

Hydrothermal synthesis of CoyZnyMn1-2yFe2O4 nanoferrites: Magneto-optical investigation

Asiri, Sarah Mousa; Sertkol, Murat; Güner, Sadık; Güngüneş, Hakan; Mujasam Batoo, Khalid; Saleh, Tawfik A.; Sözeri, Hüseyin; Almessiere, Munirah Abdullah; Manikandan, A.; Baykal, Abdulhadi (Elsevier Ltd, 2018)

Manganese ferrites nanoparticles (NPs) substituted with both Co2+ and Zn2+ simultaneously (CoyZnyMn1-2yFe2O4 NPs for y=0.0 to 0.5), have been produced by hydrothermal approach. The substitution with both Co2+ and Zn2+ ions ...
