Special Issue Information

Dear Colleagues,

In recent years, the scientific community has shown considerable interest in multifunctional materials, which exhibit the remarkable capability of manifesting multiple functionalities concurrently. These materials exhibit a unique combination of advantageous mechanical, electrical, thermal, and optical properties, thereby facilitating the execution of diverse tasks within a single structural framework. Such materials possess the potential to bring about a transformative impact across a wide range of industries, encompassing aerospace, automotive, energy, healthcare, electronics, and various other sectors.

This Special Issue will focus on the advancements in multifunctional materials that hold promise for next-generation applications. The scope of interest encompasses various aspects, including, but not limited to, the synthesis and fabrication techniques employed for multifunctional materials, the characterization and evaluation of their diverse properties, modeling and simulation approaches to comprehend their behavior, their application in structural contexts, their utilization for energy harvesting and storage purposes, their implementation in sensing and actuation systems, bio-inspired and biomimetic variations of multifunctional materials, the development of smart and responsive materials for adaptive applications, their integration into wearable devices and electronics, as well as their potential environmental applications.

Manuscripts shedding light on any of these topics or related areas are encouraged to submit.

Chemical agents pose a significant threat to social security, highlighting the crucial role of representative chemical agents adsorption in ensuring the safety our environment. This study explored the application of Magnetic Graphene Oxide Nanoplatelet Composites (MGONCs) in adsorbing the representative chemical agents such as Lewisite (L), O-ethyl S-2-diisopropylaminoethyl methylphosphonothiolate (VX), Sarin (GB), and Soman (GD). MGONCs were synthesized through a physical blending method, with the combination of graphene oxide (GO) and Fe3O4 nanoparticles at a mass ratio of 1:1. Optimization of the adsorption process involved investigating the effects of contact time, temperature, and adsorbent dosage. Remarkably, the adsorption rate of L and VX exceeded 99% when the dosage of MGONCs was 2.5 mg, with a contact time of 30 s at room temperature. Furthermore, GB and GD achieved maximum adsorption rates after a contact time of 20 min, with the dosages of MGONCs at 10 mg and 20 mg, respectively. Characterization of the magnetic composite was accomplished through XRD, TEM, VSM, FTIR, TGA, and BET analyses. Kinetical analysis revealed that the adsorption mechanism of GB and GD on MGONCs followed pseudo-second-order (PSO) kinetics, exhibiting a high regression coefficient. The calculated qe values were 0.103125 mg/g and 0.081349 mg/g, respectively. This research demonstrated the feasibility of utilizing MGONCs as highly efficient adsorbents for representative chemical agents, particularly in on-site sampling scenarios. Full article

This article sums up and compares the most important techniques for magnetic sensing of ferromagnetic nanoparticles. In addition, the most well-known magnetic sensing instruments are presented, while the advantages and disadvantages of each instrument category are summarized. Finally, a measurement system based on fluxgate magnetometers is proposed for the magnetic characterization of a cobalt-based material applicable in the catalysis process. The authors conclude that this arrangement can provide ferromagnetic material sensing with the most advantages for this catalysis application. Indeed, as nanoparticle materials can be used in many applications, like catalysis, their properties and the phase of the catalyst should be known at any time. Moreover, as the industrial processes operate at a rapid pace, the need for simple, fast, and low-cost measurement systems that will also enable in vivo material characterization is rising. Consequently, this article aims to propose the best candidate magnetic sensing method as well as the best candidate instrument for every application based on the advantages and disadvantages of each sensor.
