Welcome from the Chairs
Dear Colleagues,
It is my pleasure to invite you to join the 3rd International Online-Conference (IOCN 2022) that is hosted online by: https://sciforum.net/conference/IOCN2022.
Nanomaterials constitute an essential part of modern everyday life, both on holiday and at home. Many things we have been using for a long time contain nanosize components, though frequently we are not aware of them. For instance, mimicking nature's nanotech is becoming a big business. Many research groups around the world have turned to geckos and mussels in order to prepare adhesives that bind to dry and wet surfaces alike. Numerous technologies in the modern world rely on nanostructures, often inspired by evolution in the natural world. However, there is much unexploited potential left to explore.
The scope of IOCN 2022 on Nanomaterials is to cover the whole breadth of nanomaterials research and provide a forum for presenting and discussing new results. Topics of interest include but are not limited to:
- Synthesis, Characterization, and Properties of Nanomaterials (Session A)
- Modeling and Simulation of Nanostructures and Nanodevices (Session B)
- Carbon Nanomaterials, Graphene & 2D Materials (Session C)
- Polymer Nanomaterials, Soft Nanomaterials, Nanocoatings/Thin films, and Nanostructured Surfaces (Session D)

Show Abstract |
||||||||||||||||||||||||||||||||||||
Peroxidase was produced by a fungal isolate identified as Aspergillus flavus KIGC through ITS sequence and phylogenetic analysis on 11th day of fermentation when grown on banana peel as the sole carbon source. It was purified through ammonium sulphate, ion exchange including gel filtration. The peroxidase was purified to 8.86 folds with percentage recovery of 49.72%. The purified enzyme was a monomer of 57KDa. The purified peroxidase was immobilized on iron oxide magnetic nanoparticle and characterized using DLS, DSC, XRD, FTIR and SEM analyses. The characterization results suggest adequate nanoparticle formulation and effective enzyme immobilization therein. Optimal temperatures for both free and immobilized peroxidase were 75 and 70 °C, respectively, while the optimum pH peaks at 5.0 and 9.0 were obtained for free enzyme and 6.5 and 9.0 for immobilized peroxidase, respectively. The Michealis constant (Km) of 0.075mM and catalytic efficiency (turnover rate) of 90.66 Mol/S-1 were achieved by the immobilized peroxidase on guaiacol as substrate. The immobilized enzyme showed relatively high residual activity in towards ethanol > acetone > DMSO > methanol > Chloroform, respectively. Furthermore, metallic nanoparticle immobilized peroxidase exhibited an enhanced synthetic dyes decolorizationability compared to the free enzyme. The immobilization of peroxidase produced using organic waste as carbon source on iron oxide magnetic nanoparticles conferred considerable stability on the enzyme with great potential for various industrial applications. |

Carbon nanotubes (CNTs) represent a unique class of nanomaterials with remarkable applications in diverse domains. However, one of the many challenges still requiring improvements is undoubtedly their dispersion stability. The control of the dispersion stability of CNTs is still a challenge due to the strong of van der Waals forces that lead to their aggregation. |

Show Abstract |
||||||||||||||||||||||||||||||||||||
Beeswax is a bio-based organic phase change material. It undergoes solid to liquid phase transition at 61 ⁰C with the phase transition enthalpy of 216 J/g. The high thermal energy storage enthalpy of beeswax is suitable for maintaining constant temperature. However, the low thermal conductivity of beeswax limits the heat transfer rate. Also, beeswax should be form-stabilized to minimize leakage in the molten state. In this study, the thermal conductivity of beeswax was improved with carbon nanotube (CNT) incorporation. The leakage of molten beeswax was minimized by blending it with recycled paperboard. The beeswax-CNT-recycled paperboard nanocomposite was further coated with silicone adhesive. It ensured the retention of molten wax. Taguchi method was applied to obtain optimum constituent concentration in the nanocomposite. FTIR spectrum and SEM morphology of nanocomposite confirm physical dispersion of CNT into the fibrous matrix. DSC analysis of nanocomposites showed reduction of TES enthalpy to 98.52 J/g. The improved heat transfer rate of nanocomposite was confirmed with a special test of back surface heating. |

Self-Assembly of Polydisperse Y-Shaped Polymer Brushes under Good Solvent Conditions |
Petr Fridrich ,

N/A | N/A |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Polymers attached to the surface, e.g. polymer brushes, represent a unique way how to functionalize the surface. Its morphology is controlled by brush parameters such as grafting density, composition, chemical nature etc. and determine the response of the surface to external environment. Mixed binary brushes contain two different homopolymer branches attached to single point on the surface and exhibit a wide range of morphologies ranging from aggregates to ripple structure. Compositional fluctuations during the grafting process that hampers formation of morphology can be controlled by using Y-shaped initiators where each deposition point accepts different type of polymer. Phase behavior of Y-shaped brushes is described in theory and by simulation studies mainly for monodisperse cases. Nevertheless, real polymers are always polydisperse and using highly polydisperse polymer brings new options to control the formation of surface morphology. Here, we employ Dissipative Particle Dynamics (DPD) to study the influence of polydispersity on self-assembly of Y-shaped polymer brushes. We vary brush grafting density, composition of the branches and their incompatibility to describe complex behavior of brushes at good solvent conditions. Moreover, we introduce the polydispersity by varying chain length of one branch and keeping other branch of the brush monodisperse. We consider low and high polydispersity and restrict our investigations to polydispersity indexes (PDI) that are used in experiments. We model the polydispersity by Schultz-Zimm distribution. We show that our results for monodisperse systems agree with previous experimental and theoretical works and that ripple structure and aggregates are observed. Furthermore, the scaling of the brush height in our model agrees with theoretical predictions and with previous modeling results. In polydisperse systems, only disordered structures or aggregates are assembled by brushes with PDI < 1.5 sparsely grafted onto the surface with grafting density lower that 0.1 chains/nm2. Moreover, increasing the grafting density above 0.5 chains/nm2 triggers formation of perforated layer (PL) that is not observed in monodisperse systems. PL phase window widens with increasing the PDI up to 2 and the grafting density up to 1.0 chains/nm2. At high grafting densities and PDIs the PL phase is stable over wide range of phase diagram. Finally, we show that increasing PDI lead to asymmetry of phase diagrams. High content of polydisperse chains prefer formation of aggregates over the ripple structure and increase the order-disorder transition while high content of monodisperse chains favours ripple structure and lowers the order-disorder transition. |

Show Abstract |
||||||||||||||||||||||||||||||||||||
Medical-grade titanium implants were functionalized with hydroxyapatite (HA) coatings of marine origin (derived from fish bones or sea-shells) by Pulsed laser deposition technique. Lithium phosphate, magnesium fluoride and silver were used as doping agents in three different concentrations, of 0.5, 1 and 2 wt.%, respectively. Besides morphological, structural and compositional investigations, the synthesized coatings were also submitted to mechanical testing. SEM analysis revealed surfaces with rough morphologies, made of generally round-shaped particulates. This type of surface was shown to determine a good adhesion of grown cells and excellent in situ anchorage of implants. XRD and FT-IR investigations demonstrated the synthesis of coatings with different degrees of crystallinity, generally influenced by the concentration of the dopant and the source material. Compositional tests evidenced the presence of trace-elements generally found in the composition of the bone mineral phase, which play a key-role in its functionality. Surfaces with a strong hydrophilic behavior were demonstrated by contact angle measurements. The inferred pull-out bonding strength adherence values were three times higher than the ones imposed by international standard (> 15 MPa) in the case of implant coatings with high biomechanical loads. Taking into consideration their improved mechanical characteristics and the morphological, structural and compositional results, along with the fact that the base materials are cheap and derived from sustainable resources, one can conclude that these marine-derived materials should be considered as viable candidates to HA synthetic ones, for implant coating applications.
