Investigation into the influence of boronizing on the wear behavior of additively manufactured Inconel 625 alloy at elevated temperature
(Springer, 2023)
Directed energy deposition (DED) technology is a cost-effective additive manufacturing method widely used in the production of complex-shaped parts made of various engineering alloys as well as superalloys due to its ...
Geochemical, mineralogical and diagenetic characteristics of marine chert in the Hatay region, S-Turkey: Its origin and depositional environment
(Carpathian Journal of Earth and Environmental Sciences, 2023)
Trace elements and rare earth elements (REEs) were studied to determine the formation of chert and siliceous limestones, which are predominantly observed in the Okçular formation. Cherts are divided into four types according ...
High-temperature effect on mechanical properties of fiber reinforced concretes including waste tire rubber
(Wiley, 2023)
In this paper, concretes including three different fiber types (carbon steel fiber [CSF], forta ferro fiber [FFF], and polypropylene fiber [PPF]) with different percentages by volume (0.5%, 1%, and 1.5%) and crumb rubber ...
Experimental and Numerical Study on Flow Control Using 3-Array Submerged Vane in Laboratory Channel Bend
(MDPI, 2023)
Regulation structures such as submerged vane are needed to reduce and eliminate environmental damage due to increased flooding in rivers. In particular, scours on the outer bank due to increased flow velocities cause the ...
Decision making in the manufacturing environment using the technique of precise order preference
(Yildiz Technical University, 2023)
Wrong decisions in manufacturing systems can jeopardize the continuity of production and reduce productivity and efficiency. Therefore, it is essential to make the right decisions in solving the problems encountered in ...
Conceptual design and optimal sizing of a small unmanned aerial vehicle with fuel cell and battery-powered hybrid propulsion system by meta-heuristic algorithms based on energy consumption
(Taylor and Francis, 2023)
In this paper, a new conceptual design methodology for a hybrid propulsion system consisting of the battery and hydrogen fuel cells is presented based on the minimum energy consumption of the UAV. In this context, an ...
Presence of microplastic in the Patella caerulea from the northeastern Mediterranean Sea
(Elsevier, 2023)
This study reports first evidence of microplastic detection in the Patella caerulea collected from 5 different stations located in İskenderun Bay and Mersin Bay. A total of 160 P. caerulea specimens were examined and 40 ...
Synthesis, structural characterization and determination of the nitro-containing explosives detection potential of supramolecular lanthanum complex and Lanthana nanoparticles
(Elsevier, 2023)
A novel nanoparticle sized complex, [La(HO-C6H4-CH2COO)3(H2O)].(H2O), has been prepared by the reaction of LaIII ion and a versatile carboxylate ligand, 4-hydroxyphenylacetatic acid. The obtained complex was structurally ...
Absorbing the entire X-band via conductive polymer polyaniline coated Y3Fe5O12/NiFe2O4 hybrid composites
(Springer, 2023)
Conductive polymer coated Y3Fe5O12 (YIG)/NiFe2O4 (NFO) hybrid radar absorbing composites were studied in this work. The magnetic YIG and NFO particles were synthesized by sol-gel method, and then covered with a conductive ...
Novel Properties of q-Sine-Based and q-Cosine-Based q-Fubini Polynomials
(MDPI, 2023)
The main purpose of this paper is to consider q-sine-based and q-cosine-Based q-Fubini polynomials and is to investigate diverse properties of these polynomials. Furthermore, multifarious correlations including q-analogues ...
