Mixed Mg-Co spinel ferrites: Structure, morphology, magnetic and photocatalytic properties
(Elsevier, 2021)
CoxMg1-xFe2O4 (where x was 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1) spinel ferrites were synthesized by the sol-gel combustion method using citric acid as fuel, following the rules of propellant chemistry. Amorphous powders ...
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 ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Nonlinear vibration of a nonlocal functionally graded beam on fractional visco-Pasternak foundation
(Springer, Dordrecht, 2022)
This paper investigates the nonlinear dynamic behavior of a nonlocal functionally graded Euler-Bernoulli beam resting on a fractional visco-Pasternak foundation and subjected to harmonic loads. The proposed model captures ...
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 ...
Mass minimization of an Euler-Bernoulli beam with coupled bending and axial vibrations at prescribed fundamental frequency
(Elsevier Sci Ltd, Oxford, 2021)
The problem of determining the optimum shape of a homogeneous Euler-Bernoulli beam of a circular cross-section, in which the coupled axial and bending vibrations arose due to complex boundary conditions, is considered. The ...
Novel fractal analysis of nanograin growth in BaTiO3 thin film
(Elsevier Science Sa, Lausanne, 2020)
The grain size and the ferroelectric morphology are the two most important factors in the research and development of advanced dielectric devices. It is important to synthesize nanostructures in order to achieve optimal ...
Rolling Bearing Fault Detection in the Range of Ultrasound
(Tehnički vjesnik – Technical Gazette, 2023)
Acoustic signals have been used widely to detect the integrity of metal parts and the soundness of their contact. Diverse methods are developed to evaluate the actual quality of metal-to-metal contact having a lubricating ...
Assessment of corroded API 5L X52 pipe elbow using a modified failure assessment diagram
(Elsevier Sci Ltd, Oxford, 2021)
Pipe elbows (bends) are considered critical pressurized components in the piping systems and pipelines due to their stress intensification and the effect of bend curvature. They are prone and hence more exposed to different ...
