Calcined and natural frustules filled epoxy matrices: The effect of volume fraction on the tensile and compression behavior

Gültürk, Elif; Güden, Mustafa; Taşdemirci, Alper (Elsevier, 2013-01)

The effects of calcined diatom (CD) and natural diatom (ND) frustules filling (0–12 vol.%) on the quasistatic tensile and quasi-static and high strain rate compression behavior of an epoxy matrix were investigated ...
Diatom frustule-filled epoxy: Experimental and numerical study of the quasi-static and high strain rate compression behavior

Taşdemirci, Alper; Yüksel, Sinan; Karsu, Deniz; Gültürk, Elif; Hall, Ian W.; Güden, Mustafa (Elsevier, 2008)

In this study, centric type diatom frustules obtained from a diatomaceous earth filter material were used as filler in an epoxy resin with a weight percentage of 15% in order to assess the possible effects on the compressive ...
Thermal and acid treatment of diatom frustules

Gültürk, Elif; Güden, Mustafa (International OCSCO World Press, 2011-06)

Purpose: Diatoms, belonging to Bacilariophyta family, are single-celled microscopic (1-100 micron) plants living in aquatic environment. The diatom cell is protected inside a shell (frustule) constructed from amorphous ...
