Special Issue Information

Dear Colleagues,

Progress in technology and engineering is greatly affected by the development of advanced functional materials with improved properties. Most industrial sectors, such as construction, automobile and aerospace industries, microelectronics, sensors, medicine, security, etc., demand cost-effective materials with tunable and optimized properties (i.e., enhanced physical (magnetic or mechanical) or chemical characteristics, biocompatibility, etc.).

Another challenge is related to the miniaturization of modern devices, which tends to stimulate a rapid development of micro- and nano-scale magnetic materials, including nanostructured thin films, micro- and nano-wires, nano-dots, and nanoparticle assemblies.

Additionally, most materials’ physical and chemical properties need optimization in order to be suitable for technological applications. Materials engineering is intrinsically related to the understanding and application of the fundamental principles and laws of nature allowing the transformation at an industrial level of raw material and energy into products useful to society. However, the insecure supplies of critical materials (i.e., rare-earth or Co) could hinder the development of new technologies related to massive applications. Accordingly, the development of novel technologies and applications is critically affected by the development of new cost-effective materials and by the improvement of the physical properties of existing materials.

The overall goal of this Special Issue is to provide the most up-to-date information about recent developments of cost-effective and innovative materials with advanced functional properties, made suitable for technological applications. Both reviews and original research papers will be considered. Reviews should provide an up-to-date, well-balanced overview of the current state of the art of a particular application and include main results from different groups.

This Special Issue aims to  promote research and developmental activities in Innovative Engineering Materials and Process Engineering.

Potential topics of interest include, but are not limited to, the following:

New advanced functional materials: Ceramics and Glasses, Composites, Amorphous Materials, Biomaterials

Multifunctional Materials, Magnetic Materials

Title: Electrospun Fibers of Chitosan / PVP for the effective chemotherapeutic drug delivery of 5-Fluorouracil
Authors: Jamie J. Grant; Tatiana S. Perova; Suresh C. Pillai; et al
Affiliation: Trinity College Dublin, The University of Dublin Dublin 2, Ireland
Abstract: Electrospun nanofibrous mats consisting of chitosan (CS) and polyvinylpyrrolidone (PVP) were constructed. Optimisation of solution and process parameters was performed and resulted in an electrospun system containing a 6:4 ratio of PVP: CS. This is a significant increase in the proportion of spun CS on the previously reported highest ratio PVP:CS blend. SEM analysis showed that the nanofibrous mats with 4 wt% CS/ 6 wt% PVP (sample E) comprised homogenous, uniform fibers with an average diameter of 0.569μm. XPS analysis showed that the surface of the samples consisted of PVP. Raman and FTIR analysis showed intermolecular interactions (via H-bonding) between PVP and CS. In FTIR spectra, the contribution of chitosan to CS/PVP complexes was shown by the downshift of the C=O band and by the linear increase of intensity of C-O stretching in CS. XPS analysis showed a smaller shift at the binding energy 531 eV, which relates to the amide of the acetylated functional groups. The chemotherapy drug 5-Fu was incorporated into the constructs and cell viability studies were performed.WST-8 viability assay showed that exposure of A549 human alveolar basal epithelial cells to 10mg/mL 5-Fu loaded fibers was most effective at killing cells over 24 hours. On the other hand, the constructs with loading of 1mg/mL of drug were not efficient at killing A549 human alveolar basal epithelial cells. This study showed that CS/PVP/5-Fu constructs have potential in chemotherapeutic drug delivery systems.

Abstract: We report on routes allowing to obtain Fe-rich microwires exhibiting both the single domain wall propagation and giant magneto-impedance (GMI) effect by appropriate post-processing. Usually, these two effects were hardly achieved in the same magnetic microwire: while Co-based amorphous microwires show a high GMI effect, Fe-based amorphous microwires usually show low GMI effect, although they exhibit single domain wall (DW) propagation. However, Fe-rich microwires are less expensive and present a higher saturation magnetization. We studied the influence of post-processing on magnetic properties of Fe-rich microwires and identifined the routes to obtain Fe-rich cost-effective microwires with unique combination of magnetic properties allowing observation of fast and single DW propagation and substantial GMI effect in the same microwire. By modifying the annealing conditions, we have identified the appropriate regimes allowing to achieve remarkable improvements in GMI ratio and single DW dynamics. The observed experimental results are discussed considering the radial distribution of the magnetic anisotropy and the correlation of the GMI effect and DW dynamics with hysteresis loops.
