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 ...
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 ...
Structural investigation of mechanically activated ZnO powder
(Elsevier Science Sa, Lausanne, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
Optimization of gravity flow discharge chutes under the speed dependent resisting forces: Maximizing exit velocity
(Elsevier, Amsterdam, 2015)
Using the optimal control theory, the problem of finding profiles of gravity flow discharge chutes required to achieve maximum exit velocity of granular material under the speed dependent resisting forces is solved. A model ...
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 ...
DUV fluorescence bioimaging study of the interaction of partially reduced graphene oxide and liver cancer cells
(IOP Publishing Ltd, 2018)
The interaction of partially reduced graphene oxide (prGO) and Huh7.5.1 liver cancer cells was investigated by means of DUV fluorescence bioimaging. The prGO sample was obtained by the reduction (to a certain extent) of ...
Achieving sustainable work of the heat pump with the support of an underground water tank and solar collectors
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with the methodology of sizing a sustainable heating-cooling system, which consists of a heat pump, thermo-solar collectors and underground water tank, as a seasonal thermal energy storage. The methodology ...
Contribution to the determination of the global minimum time for the brachistochronic motion of a holonomic mechanical system
(Springer, Dordrecht, 2017)
The problem of the brachistochronic motion of a holonomic scleronomic mechanical system is analyzed. The system moves in an arbitrary field of known potential forces. The problem is formulated as an optimal control task, ...
Free vibration analysis of axially functionally graded tapered, stepped, and continuously segmented rods and beams
(Elsevier Sci Ltd, Oxford, 2018)
In this paper a new non-iterative computational technique referred to as the symbolic-numeric method of initial parameters (SNMIP) is proposed. The SNMIP represents a modification of the iterative numeric method of initial ...
