Special Issue Information

Dear Colleagues,

The study of low-dimensional materials began to gain prominence with the discovery of graphene in 2004, a single layer of carbon atoms with exceptional electrical, thermal, optical, and mechanical properties. Before this, carbon nanotubes, discovered in 1991, had already showcased remarkable strength and conductivity as one-dimensional materials. Quantum dots, zero-dimensional nanoparticles, emerged in the 1980s, offering size-tunable electronic and optical properties due to quantum confinement.

It is worth mentioning that the exploration of two-dimensional materials expanded with the discovery of monolayer transition metal dichalcogenides like monolayer molybdenum disulfide (MoS2) around 2011, which displayed versatile electronic and optical properties. The study of topological insulators introduced materials with insulating bulk states but conductive surface states, enriching our understanding. Further, the integration of various 2D materials into heterostructures, including twisted heterostructures in the 2010s, led to new phenomena and potential applications, marking significant progress in nanotechnology.

As will be seen in this Special Issue, low-dimensional materials exhibit a wide range of new properties that can be employed to fabricate improved and novel devices. The ongoing research on these materials is advancing electronics, materials science, and related fields. We would like you to consider submitting a manuscript in this field that provides detailed and rigorous methodologies or processes, as these are crucial for advancing the field and ensuring replicability and robustness in research findings.

Oral disintegration films (ODFs) offer a convenient alternative for administering active compounds with quick absorption, no need for water, customizable formulation, and promising pharmaceutical applications. This study aimed to develop chia mucilage films as a new polymer to carry vitamin C. Chia mucilage was extracted using the method of immersing the seeds in water, separated by vacuum filtration and using a sieve to remove the mucilaginous gel, then centrifuged and finally freeze-dried, with the mucilage obtained being used to produce films using the casting technique. The formulations included a control and a 1% vitamin C variant, with glycerol as a plasticizer. The produced films showed high solubility, pH close to the oral and a disintegration time of 53.17 s for the formulation with 1% vitamin C. The presence of vitamin C in the polymer matrix, as well as the interactions between them, were confirmed by DSC and FTIR spectra. On the first day of storage, after 1 min of reaction at 30 °C, the vitamin C concentration obtained was 477.50 mg/g, while at 40 °C was 411.28 mg/g. After 35 days of storage, the films showed a reduction in vitamin C concentration. Chia mucilage proved to be a promising polymer in the production of ODFs carrying vitamin C. Full article

In this study, we used Principal Component Analysis (PCA) to evaluate the physical and operational properties of palladium (Pd)-based membrane composites, focusing on variables like temperature, differential pressure (ΔP), thickness, hydrogen (H2) permeability, and H2 flux. The analysis revealed that the first two principal components explained 53.16% of the total variance, indicating moderate explanatory power. Interdependencies were observed among temperature, thickness, H2 flux, and H2 permeability, while ΔP functioned independently. This study found similarities among membranes, such as eco-friendly chitosan-based membranes, which performed comparably to conventional options like Pd–PSS and Pd–Cu/αAl2O3. Overall, PCA proved to be an invaluable tool for uncovering hidden patterns, optimizing experimental processes, and deepening the understanding of Pd-based membranes. The findings underscore PCA’s potential to enhance material performance and promote sustainable alternatives, with practical benefits for advancing hydrogen separation technologies. This study illustrates how data-driven approaches can refine material analysis and drive innovation in membrane design. Full article
