(TECHNO-PRESS, 2019)
Protection of cultural heritage and carrying it to the future are at the top of the significant topics of research and implementation in engineering in the 21st century. There are several historical structures in the ...
The effect of 2D-MoS2 doped polypyrrole coatings on brass corrosion
(Elsevier B.V., 2020)
Conductive polymers have an important potential against the corrosion applications because they arehighly resistant to chemicals besides they have homogeneous coating properties and transport metals tomore noble regions. ...
Energy absorption of thin-walled tubes enhanced by lattice structures
(Elsevier, 2019)
Thin-walled structures filled or covered by various materials have been proposed for energy absorption applications in recent years. At this point, additive manufacturing technologies provide an unprecedented opportunity ...
Effect of operational parameters on ultrasonic treatment of baker's yeast effluent
(Sakarya Üniversitesi, 2016)
In this study, ultrasound was employed to remove color and chemical oxygen demand (COD) from baker's yeast effluent. An ultrasonic homogenizator with 20kHz frequency was used for this purpose. The effect of operational ...
