Microstructure, microhardness and tensile properties of FSWed DP 800 steel
(International OCSCO World Press, 2017)Purpose: Dual phase (DP) steels are widely used in the automotive industry due to their properties of a high balance of strength and formability. However, it is known that conventional welding of high strength steel leads ... -
Microwave-assisted synthesis and biological evaluation of some coumarin hydrazides
(2018)In this work, 15 different coumarin hydrazides were successfully synthesized and screened for their antioxidant and antilipase activities. To do this, firstly, salicylaldehyde derivatives and Meldrum's Acid were reacted ... -
Monitoring of microplastic pollution in sediments along the Çoruh River Basin, NE Türkiye
(Elsevier, 2024)Microplastic (MP) pollution has become a research issue on the world agenda. Monitoring studies are essential for MP content in aquatic environments since it is the final accumulation point. The present study focused on ... -
Monitoring sediment transport in certain harbor launches in the southeastern black sea
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Abstract: The problem of shoaling on coastal structures is the result of an event that occurs as part of the natural cycle. In cases where shoaling cannot be detected or prevented, various economic and operational problems ... -
