Effect of strontium additions on the microstructural and mechanical properties of Al-17Si-4Cu-0.6Mg-3Zn (B390+2 wt%Zn) alloy
(Springer, 2022)One Al-17Si-4Cu-0.6Mg-3Zn (B390 + 2 wt%Zn) alloy and five B390 + 2 wt% Zn-Sr alloys were produced by permanent mold casting method. Microstructural evaluations were carried out with microscopic techniques. The phases of ... -
Design, synthesis and biological evaluation of novel bischalcone derivatives as potential anticancer agents
(Elsevier, 2021)Building on our previous work that discovered chalcone as a promising pharmacophore for anticancer activity, we have various other chalcone derivatives and have synthesized a series of novel bischalcone to explore their ... -
Reinforcement effect of polypropylene fiber on dynamic properties of cemented tailings backfill under SHPB impact loading
(Elsevier, 2021)Dynamic loads such as blasting may lead to diverse levels of failure in cemented tailings backfill (CTB) under diverse strain rates and frequency spectral amplitudes. Hence, changes in dynamic properties of filling due to ... -
Petrogenesis and U-Pb zircon geochronology of migmatitzation during Neo-Tethyan Jurassic magmatic arc extension: The Boroujerd example, western Iran
(Elsevier, 2021)The migmatites in the Boroujerd region, Western Iran are spatially associated with felsic and mafic magmatism. However, the genetic relationship between partial melting and magmatism in the region is unclear. Four metapelite ... -
Comparative study of the marine terraces along the Bulgarian and Turkish Black Sea coasts for determination of the tectonic effect and environmental change

An overview on MOSFET drivers and converter applications
(Taylor & Francis Ltd., 2021)The metal oxide semiconductor field effect transistor (MOSFET) drivers are among the main components for most power electronic applications. Increasing the switching frequency from kHz to MHz levels, MOSFETs' current, power ... -
Late Jurassic Paleotethyan oceanic slab break-off revealed by Sr-Nd-Hf isotopes of Na-rich adakitic granites from northwestern Turkey
(Elsevier, 2021)The Mesozoic geodynamic evolution of the Paleotethys Ocean is critical but a poorly known piece of the geological history of the Sakarya Zone, north Turkey. Here, we describe new integrated research of zircon U-Pb ... -
Influence of types and shapes of 3D printed polymeric lattice on ductility performance of cementitious backfill composites
(Elsevier, 2021)The compression properties of cementitious backfill composite (CBC) is strong, but their tension properties are weak and presents little ductility because of their low fatigue crack growth rate and resistance. Thus, proper ... -
