“…Calorimetric analysis revealed that the Extrudr BDP Flax sample exhibited three representative transformations, the first at 62.7 • C (inflection point), which can be associated with the glass transition of amorphous material components (probably PLA or copolyester), [24,25], followed by the ascending slope, which suggests an enthalpy relaxation, [26,27]. The exothermic peak at 124.5 • C (curve II) that takes place with a heat release within the 109.9-136.3 • C temperature range, could correspond to the hot crystallization of the material, the process taking place with minimal energy consumption [24,25]. The Curve III endothermic peak at 154.1 • C corresponded to the melting point of the material.…”

It is essential to combine current state-of-the-art technologies such as additive manufacturing with current ecological needs. Due to the increasing demand for non-toxic biodegradable materials and products, human society has been searching for new materials. Consequently, it is compulsory to identify the qualities of these materials and their behavior when subjected to various external factors, to find their optimal solutions for application in various fields. This paper refers to the biodegradable Polylactic acid (PLA)-based filament (commercially known as Extrudr BDP (Biodegradable Plastic) Flax) compared with the biodegradable composite material PLA-lignin filament whose constituent’s trade name is Arboblend V2 Nature as a lignin base material and reinforcement with Extrudr BDP Pearl, a PLA based polymer, 3D printed by Fused Deposition Modeling technology. Certain mechanical properties (tensile strength, bending strength and DMA—Dynamic Mechanical Analysis) were also determined. The tribology behavior (friction coefficient and wear), the structure and the chemical composition of the biodegradable materials were investigated by SEM—Scanning Electron Microscopy, EDX—Energy Dispersive X-Ray Analysis, XRD—X-Ray Diffraction Analysis, FTIR—Fourier Transform Infrared Spectrometer and TGA—Thermogravimetric Analysis. The paper also refers to the influence of technological parameters on the 3D printed filaments made of Extrudr BDP Flax and the optimization those of technological parameters. The thermal behavior during the heating of the sample was analyzed by Differential scanning calorimetry (DSC). As a result of the carried-out research, we intend to recommend these biodegradable materials as possible substituents for plastics in as many fields of activity as possible.

“…9 The possibility to intercalate organic compounds into the layers of the LDHs also make them useful for multifunctional applications, such as usage in dye sensitized solar cells, enhancement of ame retardant properties, and resistance to thermal degradation. [10][11][12][13][14][15][16] Most recently, the development of novel layered materials attracts great interest in various elds. [17][18][19][20][21] There exist many techniques to prepare LDHs, the most common being co-precipitation, urea hydrolysis, ion exchange and hydrothermal synthesis.…”

“…However, adsorption affinity of the surface area of the adsorbent is independent of the surface area and dependent on the favorable attractive interactions present at the pH value range below 7. When the pH is higher than 7, the electrostatic repulsion forces of the adsorbate-adsorbent are weakened, hence, the reduced adsorption efficiency or removal percentage of contaminants [41,49,131]. The adsorption of contaminants from water mostly depends on hydrophobic interactions between adsorbate and adsorbent, which make great contributions to the affinity of the organic anion to LDH.…”

Their exceptional characteristics and uniqueness make Layered Double Hydroxides (LDHs) and their derivatives promising two-dimensional layered materials that are suitable for several existing and future applications in diverse fields. To name a few, we can mention environmental monitoring and preservation, biotechnology, pharmaceutical and chemical processes, the design and realization of new functional polymers and new magnetic materials with a high-saturation magnetic field, and new composite materials for sustainable concrete infrastructure.The number of research and review articles in high-impact journals highlights the growing attention paid to these materials by not only academic, but also applied-science researchers. This is due to the peculiar properties of LDHs, such as their ease of synthesis even on a large scale, their chemical and thermal stability, their uniform distribution of metal cations, and their ability to intercalate anionic species within the interlayer space and possibly release them, together with their high biocompatibility.This growing interest has led to a parallel growth in the number of publications, some of which appear in this Special Issue of Crystals, presenting both research and review papers. In particular, deeper attention has been paid to innovative synthesis techniques, focusing on those with a low environmental impact, to applications for renewable energy sources, and to interlayer anions' exchange capability for drug release. The ability of Layered Double Hydroxides to form hybrid inorganic/organic nanomaterials is stressed in the review articles.We are confident that reading the articles published in this Special Issue, written by accomplished researchers working for years in the field, will be a source of inspiration to any scientist who studies LDHs within any discipline.
