Air-breathing versus conventional polymer electrolyte fuel cells: A parametric numerical study
(Elsevier, 2022)
Two mathematical models have been built for air-breathing and conventional polymer electrolyte fuel cells to explore the reasons affecting the cell performance. A parametric study has been conducted to (i) investigate how ...
Structural and optical characteristics of antimony selenosulfide thin films prepared by two-step method
(Korean Physical Society, 2022)
Antimony triselenide (Sb2Se3) is one of the most promising absorber material choices among the inorganic semiconductors that has attracted much attention today. However, highest recorded efficiencies for Sb2Se3 solar cells ...
Classification of Surfaces of Coordinate Finite Type in the Lorentz–Minkowski 3-Space
(MDPI, 2022)
In this paper, we define surfaces of revolution without parabolic points in three-dimensional Lorentz–Minkowski space. Then, we classify this class of surfaces under the condition ∆I I I x = Ax, where ∆I I I is the Laplace ...
Electromagnetic skin depth of cement paste and its thickness dependence
(Elsevier, 2022)
The skin depth delta describes the ability of electromagnetic radiation (particularly microwave) to penetrate a material. This ability is relevant to radar-related applications, electromagnetic interference shielding and ...
Self-sensing reinforced concrete for damage assessment and real time strength development in smart structures
(Taylor and Francis, 2022)
In this study, a self-sensing smart structure was developed with a novel approach. Electromagnetic wave based self-sensing structure designed by sending waves to the reinforced concrete structure through the reinforcement ...
Detailed low temperature studies on thermoelectric performance of K-doped Bi2Ca2Co2Oy ceramics fibers
(Institute of Physics, 2022)
The effect of K substitution for Ca in Bi2Ca2-xKxCo2Oy (x = 0.0, 0.05, 0.075, 0.10, and 0.125) thermoelectric ceramics, produced via laser floating zone (LFZ) method, have been systematically investigated. XRD patterns are ...
An Innovative Experimental Study on Improving the Rheological Properties of Na-Bentonite Water Based Drilling Muds using Graphene, Graphene Oxide and Graphene Oxide Functionalized with Gold Nanoparticles
(Institute of Physics, 2022)
In this study; it is aimed to improve the rheological properties of Na-Bentonite water based drilling muds (WBDM) by graphene, graphene oxide (GO) and graphene oxide functionalized with gold nanoparticles (AuNPs/GO) at ...
Why Kalina (Ammonia-Water) cycle rather than steam Rankine cycle and pure ammonia cycle: A comparative and comprehensive case study for a cogeneration system
(Elsevier, 2022)
There are many studies on the Kalina cycle and steam Rankine cycles. However, there are not enough comparative and descriptive studies on why the Kalina cycle or steam Rankine cycle should be selected. In addition to that, ...
WEDM machining of MoNbTaTiZr refractory high entropy alloy
(Elsevier, 2022)
Refractory high entropy alloys (RHEAs) have shown great promise for a multitude of advanced engineering applications due to their high mechanical stability from cryogenic temperatures to 1600 °C. However, the low ductility ...
Dynamic models for air-breathing and conventional polymer electrolyte fuel cells: A comparative study
(Elsevier, 2022)
Two dynamic models have been built for air-breathing and conventional polymer electrolyte fuel cells (PEFCs) in order to comparatively investigate the impacts of some key parameters on the transient response to load ...
