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 |
||||||||||||||||||||||||||||||||||||
Gold nanoclusters (AuNCs) with diameter less than 2 nanometres have fluorescent properties. These nanoclusters can be prepared by microwave assisted synthesis using BSA (bovine serum albumin) as a template (1). During the synthesis, Au(III) ions are reduced to Au(I) or Au(0) which are bonded to BSA forming thus Au(I)-BSA complexes and/or AuNCs-BSA, respectively. Here, femtosecond stimulated Raman spectroscopy (FSRS), an ultrafast nonlinear optical technique is used to study vibrational structure of Au(I)-BSA complexes and AuNCs-BSA. FSRS has time resolution comparable to the vibrational period of molecular movements (ps to fs) and energy resolution less than 10 cm-1. Three laser pulses are exploited in a typical FSRS experiment: actinic pulse, Raman pulse and probe pulse (2). According to our preliminary results, FSRS represents a very promising tool in the investigation of Au(I)-BSA complexes and AuNCs-BSA systems. This research was funded by Grant Agency of the Czech Republic, grant number 19-03207S. References: (1) P.

We examined the optoelectronic properties of atomically thin 1D van der Waals heterostructures comprising the single-walled carbon nanotubes (NT) wrapped by insulating BN NT layers and MoS2 NT outer layers ([email protected]@MoS2NT). We will present the equilibrium properties of such materials (through optical absorption, transmission, reflection, ellipsometry, Raman scattering, THz spectroscopy, and XPS studies) along with the transmission electron microscopy measurements. Through all of these techniques, we evaluated intertube excitonic interactions in addition to the charge transport characteristics of a large area 1D heterostructure. In addition, non-equilibrium, ultrafast pump–probe spectroscopy across the visible and terahertz frequency ranges identified that, in the MoS2 nanotubes, excitons coexisted with a prominent population of free charges. |

sciforum-057609 | Formulation of a Multifunctional Nanocomposite Hydrogel Based on Natural Polysaccharides, Biogenic Copper Nanoparticles and Essential Oils | , | N/A |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Background: Copper nanoparticles are of tremendous interest due to their strong antibacterial properties, thereby having potential to enhance not only the physical and biochemical characteristics of hydrogels, but also their antimicrobial activity. Objective: the goal of this study was to develop a multifunctional hydrogel embedded with copper nanoparticles that were manufactured in an eco-friendly manner. Material and Methods: Copper nanoparticles were biologically synthesized using Cinnamon extract which was mixed with the CuSO4 (pentahydrate copper sulphate) solution (0.1 M) in a 1:5 ratio. The CuNPs suspension was primarily characterized by UV–Visible spectroscopy, the spectrums being recorded from 200 to 800 nm. Xanthan gum, a natural polysaccharides, was used as thickening agent in the formulation of the following hydrogels: control gel, with CuSO4 alone), G1, with biogenic CuNPs and G2 with CuNPs and essential oils (oregano, cinnamon, clove, eucalyptus, thyme, and lavender). The Kirby-Bauer diffusimetric method was used to assess comparatively the antimicrobial activity against Gram-positive, Gram-negative bacteria and fungal species for the formulated gels. Results: The presence of the copper nanoparticles was confirmed by the presence of a surface plasmon resonance (SPR) peak recorded at 234-255 nm. The lowest antimicrobial activity was observed in the case of control hydrogel. Hydrogel G1 showed significantly better antimicrobial activity, especially on Staphylococcus epidermidis and Candida albicans. Hydrogel G2, embedded with biogenic CuNPs and essential oils, presented a higher antimicrobial activity against both Gram-positive and negative bacteria. It also displayed antibiotic activity against MRSA ATCC 33591, a methicillin-resistant Staphylococcus aureus strain with public health significance. Conclusions: When coupled with the specified essential oil blend, copper sulfate demonstrated strong synergistic antibacterial action. Altogether, this work assessed and validated the in vitro antibacterial activity of a polysaccharides-based composite hydrogel comprising biologically synthesized copper nanoparticles and essential oils with potential applications in both human and veterinary medicine. |

sciforum-058216 | MNPs-Enriched Biomaterials as Promising Candidates for Nervous Tissue Engineering Applications | , , , , , | N/A |

Show Abstract |
||||||||||||||||||||||||||||||||||||
Nervous tissue regeneration represents a huge challenge in tissue engineering and therefore, numerous strategies are being investigated for this purpose. Current approaches are focused on the use of magnetic biomaterials to support nerve regeneration, since magnetic field was proved to have a beneficial effect on neuronal differentiation. Our aim was to develop and investigate the cytocompatibility and potential of natural-based materials enriched with magnetic nanoparticles (MNPs) to support the growth, viability and proliferation of neural stem cells (represented by NE-4C cell line, CRL-2925, ATCC). These composites were developed using electrospinning technique and were enriched with different concentration of MNPs (0.5% -2%, to be compared to a pure fish gelatin control material) then they were seeded with NE-4C cells and maintained in standard culture conditions for up to seven days. Cell viability and proliferation were tested using the MTT assay, while eventual cytotoxic effects were evaluated based on lactic dehydrogenase (LDH) release in culture medium. The proportion of live and dead cells in contact with MNPs-enriched scaffolds was revealed using Live/Dead assay. Investigation of changes in cytoskeleton distribution and focal adhesion assembly was observed by immunolabeling and confocal microscopy. Our results indicated that all tested scaffolds proved to be biocompatible with neural stem cells and didn’t induce any significant cytotoxic effects for up to one week of in vitro culture. MNPs concentration influenced proportionally the rate of cell growth and proliferation, while cytoskeleton immunolabeling revealed an elongated profile of actin microfilaments and emphasized focal adhesion kinase distribution, suggesting beneficial effects of MNPs-enriched composites. Thus, biomaterials embedding low concentrations of MNPs display good interaction with neural stem cells and could be used in further studies for nervous tissue regeneration. This work was supported by PN-III-P1-1.1-TE-2019-1191/MAGNIFICENT grant. |

Show Abstract |
||||||||||||||||||||||||||||||||||||
The rechargeable aqueous zinc ion battery has great promise owing to its non-flammability and low cost, but is still limited by the lack of suitable cathode materials. Vanadium oxides cathode materials suffer from unsatisfactory rate and cycle performance for their poor conductivity and vanadium dissolution in aqueous solutions. Herein, we reported the zinc vanadium oxides with different stoichiometric converted from in-situ electrochemical oxidation of VOOH precursors in various space groups. The introduction of zinc atoms not only improves the conductivity of the materials but also stabilizes the layered structure without hindering ion migration and inhibits vanadium dissolution, thus greatly optimizing the comprehensive behaviors of the battery. The materials obtained through this route possess low crystallinity and such disordered structure facilitates electrolyte penetration and provides shortcuts for ion transportation. Zn0.36V2O5·nH2O has a specific capacity of 508.3 mAh/g and the retention of 95% and 80% after 2000 and 5000 cycles respectively. |
