(Springer International Publishing Ag, 2021)
Polyimides, high-performance polymers with superior properties such as high temperature stability, resistance to solvents and high strength, can be used in high-tech applications of the aerospace and aviation, medical or ...
B4C particulate-reinforced Al-8.5 wt% Si-3.5 wt% Cu matrix composites: Powder metallurgical fabrication, age hardening, and characterization
(Elsevier Sci Ltd, 2021)
The present work investigates microstructural and mechanical properties of B4C particulate-reinforced Al-8.5 wt % Si-3.5 wt% Cu matrix composites prepared by a successive process of mechanical alloying (MA), cold pressing, ...
Novel SWCNT-hybrid nanomaterial functionalized with subphthalocyanine substituted asymmetrical zinc (II) phthalocyanine conjugate: Design, synthesis, characterization and sensor properties for pesticides
(Elsevier Science Sa, 2021)
The novel asymmetric zinc (II) phthalocyanines containing one ethyloxy azido and three iodine (Iodo-Pc) or subphthalocyanine (SubPc-Pc) groups were designed and synthesized for the first time. These novel phthalocyanines ...
Investigation of the surface properties of dibutyl amine modified poly(styrene) based polymer by inverse gas chromatography method
(Springer, 2021)
In the present study, poly(vinyl benzyl chloride) (PVBC) was prepared by the radical polymerization method. Then, PVBC was reacted with dibutyl amine to obtain tertiary amine-modified poly(styrene) based polymer (PVBC-Dibutyl ...
A comparative experimental study on the impact strength of standard and asymmetric involute spur gears
(Elsevier Sci Ltd, 2021)
Gears are one of the main components of the power transmission systems and are used in various fields. Problems caused by sudden load changes in mobile systems are frequently encountered today. Gear dynamics have become ...
Mechanical characteristics and hydrophobicity of alkyl ketene dimer compatibilized hybrid biopolymer composites
(Wiley, 2021)
In this study, the effect of alkyl ketene dimer (AKD) on the mechanical and physical properties of natural fiber (NF) and glass fiber (GF) reinforced poly(lactic acid) (PLA) composites were investigated in detail. The ...
A review on treatment of membrane concentrates generated from landfill leachate treatment processes
(Elsevier, 2021)
Landfill leachate (LL) is highly toxic wastewater and comprises various pollutants such as organic compounds, biological organisms, xenobiotics, heavy metals, inorganic salts, and ammonia. The integration of conventional ...
Riemannian Warped Product Submersions
(Springer Basel Ag, 2021)
In this paper, we introduce Riemannian warped product submersions and construct examples and give fundamental geometric properties of such submersions. On the other hand, a necessary and sufficient condition for a Riemannian ...
Bioaccumulation and biomagnification of potential toxic elements (PTEs): An Avicennia germinans-Uca rapax trophic transfer story from Jobos Bay, Puerto Rico
(Elsevier, 2021)
In southern Puerto Rico along the coastline bordering the Jobos Bay National Estuarine Research Reserve, environmental encroachment has exposed mangrove forest to different sources of pollution. Potentially toxic element ...
Evaluation of pesticide residues in fruits and vegetables from the Aegean region of Turkey and assessment of risk to consumers
(Springer Heidelberg, 2021)
Pesticides may cause a potential risk to human health when applied in excess to control pests, diseases, and weeds in crop fields. In the current study, conducted in the Aegean region of Turkey from 2012 to 2016, a total ...
