Nonlocal mass-nanosensor model based on the damped vibration of single-layer graphene sheet influenced by in-plane magnetic field
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Nano-materials such as graphene sheets have a great opportunity to be applied in development of a new generation of nanomechanical sensors and devices due to their unique physical properties. Based on the nonlocal continuum ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier Sci Ltd, Oxford, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100-240 min) and ...
Investigation of ZnFe2O4 spinel ferrite nanocrystalline screen-printed thick films for application in humidity sensing
(Wiley, 2019)
Zinc ferrite nanocrystalline powder was obtained by solid state synthesis of starting zinc oxide and hematite nanopowders. Field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), ...
The effect of ball milling on properties of sintered manganese-doped alumina
(Elsevier, 2019)
Alumina-based compounds have many technological applications and attract great attention even after decades of investigation, due to their good chemical, electrical, and mechanical properties. A mixture of several alumina ...
Multistep generalized transformation method applied to solving equations of discrete and continuous time-fractional enzyme kinetics
(Elsevier Science Bv, Amsterdam, 2017)
In this paper, Caputo based Michaelis-Menten kinetic model based on Time Scale Calculus (TSC) is proposed. The main reason for its consideration is a study of tumor cells population growth dynamics. In the particular case ...
Closed-form solution for the free axial-bending vibration problem of structures composed of rigid bodies and elastic beam segments
(Elsevier Science Inc, New York, 2020)
In this paper, the coupled axial-bending vibration of planar serial frame structures composed of rigid bodies and Euler-Bernoulli beam segments is considered. The corresponding mode orthogonality conditions for this kind ...
Workspace design for crane cabins applying a combined traditional approach and the Taguchi method for design of experiments
(Taylor & Francis Ltd, Abingdon, 2016)
Procedures in the development process of crane cabins are arbitrary and subjective. Since approximately 42% of incidents in the construction industry are linked to them, there is a need to collect fresh anthropometric data ...
Controllable synthesis of Fe3O4-wollastonite adsorbents for efficient heavy metal ions/oxyanions removal
(Springer Heidelberg, Heidelberg, 2019)
Iron oxide, in the form of magnetite (MG)–functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous ...
Statistical methods for designing a Geiger-Muller counter suitable for an early warning system
(Elsevier, 2022)
The paper discusses statistical methods that can be applied when constructing the Geiger–Muller counters to obtain the same response to radiation, regardless of their dimensions. This issue is relevant for the improvement ...
The simplified method for the assessment of the potential for thermal energy recovery from the manufacturing processes of mushrooms compost
(Elsevier, Amsterdam, 2017)
This study deals with the manufacturing process of compost production, followed by the release of large amounts of heat. The wheat straw and manure of broilers were the basic components of the raw mixture, monitored during ...
