The only option to meet the energy demand is via fossil fuels. Global warming and environmental pollution are caused by the usage of fossil fuels and the fast expansion of industry. In addition, relying on renewable energy sources is vital due to the finite availability of fossil fuels. The most promising renewable energy source in the world is solar energy, which is generally accessible on the surface of the globe. In the solar flat plate collector, solar energy can be transformed into thermal energy. The working fluid employed in the collector is the only factor that influences its thermal efficiency.The majority of research found that increasing the collector's thermal efficiency can be accomplished by substituting high thermal conductivity fluids called nanofluids and hybrid nanofluids for the working fluid. A few decades ago, studies involving nanofluids in solar collectors were carried out. In order to significantly increase the efficiency of solar collectors employing hybrid nanofluids, researchers are currently working on these devices. By replacing one fluid in solar thermal systems with high thermal conductivity fluid, larger effectiveness has been achieved. Nanofluids offer larger thermal conductivity values over their base fluid. By using these nanofluids in solar thermal systems can provide the augmented heat transfer coefficient, effectiveness and thermal performance.Hybrid nanofluids are high thermal conductivity fluids compared to mono-dispersed nanofluids. Usage of hybrid nanofluids enhances the fluid thermal properties in solar thermal systems including the thermal conductivity, density, viscosity and specific heat. The tics, stability analysis and application of mono and hybrid nanofluids in solar thermal systemsspecifically to flat plate collectoris critically reviewed and presented in this paper.

Researchers in the field of thermal engineering have since devised strategies of combined passive methods for further heat transfer enhancement. From the available literature, the employment of nanofluids, coupled with extended surfaces is scarce, with limited studies optimizing both techniques. The current investigation summarizes the combined effects of nanofluids coupled with various types of extended surfaces, within numerous applications. Parameters involving the nanofluid type, volume concen-tration, fin geometry, and flow conditions were examined, whereby their respective effects were investigated on the thermal performances. It was deduced that the effects of surfactants, nanoparticle volume concentration, and Reynolds number significantly contributed to the heat transfer enhancement. The review presents a trend finding that nanoparticle volume concentration would positively contribute to heat transfer enhancement, up to an extent. Surpassing the optimal concentration would lead to lower Brownian motions associated with higher viscosity and density. In terms of extended surfaces, the state-of-the-art review denoted that each fin design possesses a unique attribute that alters the thermal and hydraulic performances. Nevertheless, researchers fabricating novel fin designs should highly prioritize the effects on pressure drop when employing fins. Combining both techniques, the nanofluids and extended surfaces achieved remarkable results. The outstanding results could potentially achieve the standards of active methods, for a fraction of the operational cost. Concluding, the information surrounding the present review may be of aid to researchers developing new ap-proaches utilizing nanofluids and extended surfaces.}, keywords = {Industry; Heat Transfer enhancement; Nanofluid; fin; geometrical effects; Compound methods}, year = {2023}, eissn = {2590-1230} } @article{MTMT:34685076, title = {SDS-Modified Iron Oxide Magnetic Nanoparticles for Removing of Methylene Blue from Aqueous Solution}, url = {https://m2.mtmt.hu/api/publication/34685076}, author = {Magomedov, K.E. and Omelyanchik, A.S. and Vorontsov, S.A. and Čižmár, E. and Rodionova, V.V. and Levada, E.V.}, doi = {10.3103/S1062873823702027}, journal-iso = {BULL RUSS ACAD SCI PHYS}, journal = {BULLETIN OF THE RUSSIAN ACADEMY OF SCIENCES - PHYSICS}, volume = {87}, unique-id = {34685076}, issn = {1062-8738}, abstract = {Abstract: It is shown that surface-modified magnetic iron oxide nanoparticles with an average size of about 10 nm have a high adsorption capacity for the sorption of pollutants from wastewater.

We adopt the single-phase Tiwari-Das model. The governing equations are transformed to a set of similarity differential equations with the help of similarity transformation, before being solved numerically using Maple 20. Validation of the velocity gradient and temperature solutions is achieved with the second-order implicit finite difference Keller Box method. Further validation is included for the special case of no-slip nanofluid flow in the absence of viscous heating. The effects of the parameters, namely velocity slip, thermal jump, channel apex angle, Eckert number, Prandtl number, Reynolds number, and nano-particle volume fraction on velocity, temperature, skin friction, and heat transfer rate are investigated in detail. It is found that with increasing velocity slip, for water-TiO2 and ethylene glycol-TiO2 nanofluids, the channel bulk flow is decelerated whilst with greater solid (nanoparticle) volume and in the presence of momentum slip, the flow is also retarded. With the increasing semivertex angle, the channel flow is generally accelerated. An increase in divergent semiangle leads to decelerate the flow from the centerline for the core flow region, whereas near and at the channel wall, it results in a weak acceleration. Higher temperatures are achieved with greater thermal slip values, for both water-TiO2 and ethylene glycol-TiO2 nanofluids, whereas for greater nanoparticle volume fraction, temperatures are weakly decreased for water-TiO2 whereas a more significant decrease is observed for ethylene glycol-TiO2 nanofluid. With a greater diverging channel angle, a substantial decrease in temperatures is caused by greater Reynolds numbers, and the reverse effect is computed for the converging channel. The novelty of the current work is that it extends previous studies to include multiple slip effects and viscous heating (Eckert number effects), which are shown to exert a significant influence on heat and momentum transfer characteristics.

This review tries to collect and analyze the available information in this field and to offer it already dissected to researchers, focusing on the preparation methods and how nanoparticles affect the main properties of the base fluids. Here we also addressed the influence of different parameters as particle characteristics or environmental conditions in nanofluids performance, the evolution with time of the measured properties, or the neighboring relationship of nanofluids with other transformer components. In this sense, the most reviewed articles reflect enhancements of thermal conductivity or dielectric strength, as well as an improvement of time evolution of these properties, with respect to those that are found in base fluids, and, also, a better interaction between these nanofluids and dielectric cellulosics. Thus, the use of dielectric nanofluids in transformers may allow these machines to work safer or over their design parameters, reducing the risk of failure of the electrical networks and enhancing their life expectancy.

Additionally, the thermal conductivity of nanofluids is high therefore, they are more useful for heat transportation. Evaluation of entropy generation has been a helpful technique for tackling improvements in thermal features because it provides information that cannot be obtained via energy analysis. For thermodynamic irreversibilities, a good approximation is the rate of entropy generation. As a result of a reduction of entropy production, energy transport infrastructure has become more efficient. This study aims to analyse the bioconvective flow of nanofluid flow through a stretching sheet in the occurence of gyrotactic motile microorganisms. A magnetised nanomaterial model with thermophoretic and Brownian diffusion properties is analysed. The impacts of activation energy, temperature dependent and exponential base heat source are investigated in this analysis. The entropy generation of the system is also observed for nanofluid flow. The mathematical model is developed as partial differential equations. The governing equations are reduced to a dimensionless system of ordinary differential equations by applying similarity transformations. The ODEs are tacked numerically with the aid of shooting scheme in commercial software MATLAB. For graphical and numerical results of flow controlling parameters versus subjective fields, the commercial software MATLAB tool bvp4 is used with the shooting scheme.

Furthermore, the consequence of thermal radiation and entropy of the system is considered. The porous medium with activation energy is also taken into consideration.

Nanofluid studies have become an important undertaking from both the basic and applied sciences viewpoint. Nanofluids have been considered a means to surpass the performance of the heat transfer rate of conventional heat transfer fluids because they exhibit several novel thermal transport phenomena. In this review chapter, the objective is two-fold: (a) reviewing in broad strokes of the relevant literature on current understanding and the developments of nanofluids over the past few years, some important issues, stream of thought in ongoing undertakings, nanotechnology policies, with the intent of reaching a broad technical audience, and (b) emphasizing current and potential applications of nanofluids. Emphasis is placed on the second objective considering that industrial applications of nanofluids have not been well addressed in the literature. The need for further investigation is identified throughout. The present review collates the relevant literature and examines the dynamics and complexities of nanofluids. An exhaustive discussion, however, goes beyond our present purposes. In summary, challenges, gaps, and outlook on nanofluids are discussed based on their current development. Also, there have been wide-ranging demonstrations of the potential applications of nanofluids.

The 1 wt.% CuO-PANI nanocomposite was selected for the heat transfer study for nanofluid concentration in the range of 0.05 to 0.3 volume % and Reynolds number range of was 1080 to 2160 (+/- 5). Around 37 % enhancement in the heat transfer coefficient was observed for 0.2 volume % of 1 wt.% CuO-PANI nanocomposite in the base fluid. in addition, significant enhancement in the heat transfer coefficient was observed with an increase in the Reynolds number and percentage loading of CuO nanoparticle in Polyaniline (PANI).}, keywords = {ultrasound; heat transfer coefficient; CuO-PANI nanocomposite based nanofluid; helical coil tube heat exchanger; CuO loading}, year = {2020}, eissn = {1587-3765}, pages = {271-282} } @article{MTMT:31436014, title = {Investigation of therapeutic-like irradiation effect on magnetic hyperthermia characteristics of a water-based ferrofluid with magnetite particles}, url = {https://m2.mtmt.hu/api/publication/31436014}, author = {Lazic, D. and Malaescu, I and Bunoiu, O.

The presented work reviews principal results that were obtained in thorough investigations of ferrofluid’s stability regarding changes in the structure at nanoscale under various conditions, including the determination and analysis of the agglomeration regimes in biocompatible ferrofluids for biomedical applications. The structural features of the ferrocolloids and concomitant surfactant solutions were revealed and further analyzed principally relying on the data of Small-Angle Neutron Scattering (SANS). Thereby, for magnetic fluids prepared on the basis of nonpolar liquids (benzene, decalin) with magnetite nanoparticles covered by a single-layer shell of monocarboxylic acids, the studying of the effect of surfactant excess showed a tendency to a significant enhancement of the effective attraction between free (non-adsorbed) acid molecules. This explains the sharp and sudden loss of a ferrofluid’s stability that occurs because of the liquid crystal transition when exceeding some critical concentration of an acid. This transition depends strongly on an interparticle solvent-acid interaction and peculiarity of the different critical concentrations is for different solvents. For an aqueous ferrofluid (nanomagnetite stabilized with a double-layered shell of sodium oleate (SO)) that is used as a precursor for a biocompatible modification with polyethylene glycol (PEG), the fraction of micelles of non-adsorbed surfactant and its change under modification were found by SANS. The comparison with another kinds of water-based ferrocolloids showed the different rate of surfactant adsorption on magnetite particles surface depending on the surfactant type. The aggregate reorganization and its growth in the ferrofluid after ‘PEGylation’ were observed. In order to illuminate the possible influence of the micelle formation with free surfactants on this process in the presence of polymer, the SANS study was performed on mixed SO/PEG aqueous solutions. SANS results revealed drastic morphological and interacting changes of micelles due to addition of PEG. In particular, it was concluded the screening of the micelle interaction due to the formation of an effective PEG shell around micelles at high (about 10 vol%) concentration of the polymer. © 2018, Springer International Publishing AG.}, keywords = {FLUIDS; NANOPARTICLES; Solutions; Micelles; MAGNETISM; Surface active agents; Synthesis (chemical); Liquids; biocompatibility; Biomedical applications; MAGNETITE; Liquid crystals; MAGNETIC FLUIDS; Organic solvents; neutron scattering; Medical applications; Magnetite Nanoparticles; SURFACTANT ADSORPTION; Nanomagnetics; SCATTERING TECHNIQUES; Magnetic nano-particles; Stabilization mechanisms; Critical concentration; monocarboxylic acids; Liquid crystal transition}, year = {2018}, pages = {205-226} } @article{MTMT:3397938, title = {Magnetic fluids: Structural aspects by scattering techniques}, url = {https://m2.mtmt.hu/api/publication/3397938}, author = {Petrenko, VI and Nagornyi, AV and Gapon, IV and Vekas, L and Garamus, VM and Almásy, László and Feoktystov, AV and Avdeev, MV}, doi = {10.1007/978-3-319-61109-9_10}, journal-iso = {SPRINGER PROC PHYS}, journal = {SPRINGER PROCEEDINGS IN PHYSICS}, volume = {197}, unique-id = {3397938}, issn = {0930-8989}, year = {2018}, eissn = {1867-4941}, pages = {205-226} } @article{MTMT:30478346, title = {Transient peristaltic diffusion of nanofluids: A model of micropumps in medical engineering}, url = {https://m2.mtmt.hu/api/publication/30478346}, author = {Tripathi, Dharmendra and Bhushan, Shashi and Beg, O.

If mobile, HS may enhance actinide solubility due to strong complexing properties. At the same time, they can retard actinide migration by reducing mobile actinides in their higher-valence states to less mobile III- and IV-valence species. If HS are present as mineral surface coatings, they can increase actinide retention on these surfaces. Therefore, gaining control over redox and surface-active properties of HS through directed modification of these natural polyfunctional nanomaterials could provide for nature-like nanotechnology solutions for remediation. To elucidate the roles of the particular structural features present within natural humic macromolecules pertinent to interactions with actinides, an original approach was developed by the authors of this manuscript to design humic materials with customized properties. These "designer" HS are enriched with redox, complexing, or surface-active structural units, which in turn magnifies the desired properties of parent natural humic materials (e.g., reducing capacity) or enables the acquisition of new properties (e.g., formation of covalent bonds with mineral surfaces). This chapter explains synthetic pathways that can be used for manufacturing functional humic derivatives having the desired remedial properties. Two major types of humic derivatives are considered here: (1) those enriched with quinonoid moieties (hydroquinone and catechol units), and (2) those with incorporated alkoxysilyl groups. The data on designer humics with enhanced redox capacity and acquired mineral adhesion capacity are provided here. Particular attention is also paid to the in situ immobilization of alkoxysilyl humic derivatives on solid surfaces and the use of atomic force microscopy (AFM) to characterize the surface morphology of resultant humic nanocoatings. These stationary surfaces of humic derivatives exhibit exceptional capacities to reduce and sequester Pu(V) and Np(V). The potential for developing nature-inspired nanotechnology solutions for remediation, based on a use of humic functional derivatives and coatings, is examined. The in situ installation of humic permeable reactive barriers in an actinide-contaminated aquifer is discussed as a viable alternative remediation solution to deep subsurface radioactive plumes. © 2014 John Wiley & Sons, Inc.}, keywords = {DESIGN; DESIGN; PHENOLS; COATINGS; NANOPARTICLES; NANOPARTICLES; nanostructured materials; atomic force microscopy; MINERALS; Surface Properties; nanomaterials; Aquifers; Actinides; Plutonium; Plutonium; Nanotechnology; Groundwater pollution; Remediation; Remediation; humic substances; humic substances; Neptunium; Neptunium; actinide; Surface-active property; Plutonium compounds; Nanocoatings; Contaminated environment; Permeable reactive barriers; Nano-coatings; Directed modifications; nature-like technologies; Functional derivatives; Nature likes}, year = {2015}, pages = {483-501} } @{MTMT:25552481, title = {Humic Functional Derivatives and Nanocoatings for Remediation of Actinide-Contaminated Environments}, url = {https://m2.mtmt.hu/api/publication/25552481}, author = {Perminova, IV and Kalmykov, SN and Shcherbina, NS and Ponomarenko, SA and Kholodov, VA and Novikov, AP and Haire, RG and Hatfield, K}, booktitle = {Nanomaterials for Environmental Protection}, doi = {10.1002/9781118845530.ch29}, publisher = {Wiley-Blackwell Publishing Ltd.}, unique-id = {25552481}, year = {2015}, pages = {483-501} } @article{MTMT:24387721, title = {In-situ precipitation of ultra-stable nano-magnetite slurry}, url = {https://m2.mtmt.hu/api/publication/24387721}, author = {Ramimoghadam, D and Bagheri, S and Hamid, SBA}, doi = {10.1016/j.jmmm.2014.12.005}, journal-iso = {J MAGN MAGN MATER}, journal = {JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS}, volume = {379}, unique-id = {24387721}, issn = {0304-8853}, year = {2015}, eissn = {1873-4766}, pages = {74-79} } @article{MTMT:25217700, title = {Review on thermal properties of nanofluids: Recent developments}, url = {https://m2.mtmt.hu/api/publication/25217700}, author = {S A, Angayarkanni and John, Philip}, doi = {10.1016/j.cis.2015.08.014}, journal-iso = {ADV COLLOID INTERFAC}, journal = {ADVANCES IN COLLOID AND INTERFACE SCIENCE}, volume = {225}, unique-id = {25217700}, issn = {0001-8686}, year = {2015}, eissn = {1873-3727}, pages = {146-176} } @article{MTMT:25186041, title = {Magnetic nanoparticles for magnetic drug targeting}, url = {https://m2.mtmt.hu/api/publication/25186041}, author = {Stefan, Lyer and Raminder, Singh and Rainer, Tietze and Christoph, Alexiou}, doi = {10.1515/bmt-2015-0049}, journal-iso = {BIOMED TECH}, journal = {BIOMEDIZINISCHE TECHNIK}, volume = {60}, unique-id = {25186041}, issn = {0013-5585}, year = {2015}, eissn = {1862-278X}, pages = {465-475} } @article{MTMT:33056401, title = {Monodisperse sodium oleate coated magnetite high susceptibility nanoparticles for hyperthermia applications}, url = {https://m2.mtmt.hu/api/publication/33056401}, author = {Araújo-Neto, R.P. and Silva-Freitas, E.L. and Carvalho, J.F. and Pontes, T.R.F. and Silva, K.L. and Damasceno, I.H.M. and Egito, E.S.T. and Dantas, A.L. and Morales, M.A. and Carriço, A.S.}, doi = {10.1016/j.jmmm.2014.04.001}, journal-iso = {J MAGN MAGN MATER}, journal = {JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS}, volume = {364}, unique-id = {33056401}, issn = {0304-8853}, abstract = {We report a simple and low cost methodology to synthesize sodium oleate coated magnetite nanoparticles for hyperthermia applications.

In the present work, magnetite nanoparticles (MNPs) were synthesized and stabilized in aqueous medium with different carboxylic compounds (citric acid (CA), polyacrylic acid (PAA), and sodium oleate (NaOA)), in order to prepare well stabilized magnetic fluids (MFs). The magnetic nanoparticles can be used in the magnetic resonance imaging (MRI) as contrast agents. Magnetic resonance relaxation measurements of the above MFs were performed at different field strengths (i.e., 0.47, 1.5 and 9.4 T) to reveal the field strength dependence of their magnetic responses, and to compare them with that of ferucarbotran, a well-known superparamagnetic contrast agent. The measurements showed characteristic differences between the tested magnetic fluids stabilized by carboxylic compounds and ferucarbotran.

Their colloidal stability under physiological conditions (blood pH ∼ 7.2-7.4 and salt concentration ∼0.15 M) and more in high magnetic field gradient is crucial. Magnetite or maghemite nanoparticles are used in general. In the present work, magnetite nanoparticles were stabilized with different compounds (citric acid (CA) and phosphate) and sodium oleate (NaO) as the most used surfactant in the stabilization of MFs. The adsorption and overcharging effect were quantified, and the enhancement in salt tolerance of stabilized systems was studied. Adsorption, electrophoretic mobility and dynamic light scattering (DLS) measurements were performed. The electrolyte tolerance was tested in coagulation kinetic measurements. Above the adsorption saturation, the nanoparticles are stabilized in a way of combined steric and electrostatic effects. The aim was to research these two important effects and demonstrate that none of them alone is enough. The phosphate was not able to stabilize the ferrofluid in spite of our expectation, but the other two additives proved to be effective stabilizing agents. The magnetite was well stabilized by the surface complexation of CA above pH ∼ 5, however, the salt tolerance of citrate stabilized MFs remained much below the concentration of physiological salt solution, and more the dissolution of magnetite nanocrystals was enhanced due to Fe-CA complexation in aqueous medium, which may cause problems in vivo. The oleate double layers were able to stabilize magnetite nanoparticles perfectly at pH ∼ 6 preventing particle aggregation effectively even in physiological salt solution. © 2008 Springer-Verlag.}, year = {2008}, pages = {29-37}, orcid-numbers = {Jedlovszky-Hajdú, Angéla/0000-0003-2720-783X; Csákiné Tombácz, Etelka/0000-0002-2068-0459; Nyergesné Illés, Erzsébet/0000-0002-2901-9616} }
