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, ...
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 ...
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 ...
Sliding mode controller-based switched-capacitor-based high DC gain and low voltage stress DC-DC boost converter for photovoltaic applications
(Elsevier Sci Ltd, 2021)
High-gain DC-DC power boost converters blocks have been converted to the main transitional topologies for the PV applications to enhance the level of the generated voltages of these panels for grid applications. The single ...
One-Pot Preparation of Electroactive Shape Memory Polyurethane/Carbon Black Blend
(Springer, 2021)
Shape memory polymers are the materials that can recover their original shape after a large deformation when exposed to an external stimulus such as electric field, pH, temperature, light, magnetism or humidity. With these ...
Host-guest complex properties of calix[4]arene derivatives: a DFT study of adsorption and sensing of an anticancer drug, 5-fluorouracil
(Springer Wien, 2021)
In this study, it has been reported the host-guest complex properties of calix[4]arene compounds (the 3rd generation supramolecule) against the 5-fluorouracil (5-FU) anticancer drug by density functional theory calculations ...
Phase transition of ultrasonically sprayed VOx thin films: The role of substrate temperature
(Elsevier Gmbh, 2021)
In this study, vanadium oxide (VOx) semiconductor films were deposited on glass substrates using ultrasonic spray pyrolysis technique. The effect of the substrate temperature on the physical properties of the deposited ...
