Summary: This study reports on the adsorption of tetracycline using magnetic chitosan as the adsorbent. The highest adsorption capacity was achieved at pH 7.0, and the efficiency of the adsorbent depended on pH, initial concentration, and dosage. Ionic strength significantly affected the process. The Sips and Elovich models provided the best fit for the experimental data, indicating heterogeneous surface adsorption predominantly through chemical mechanisms. The adsorption of tetracycline was governed by hydrogen bonds and cation-pi interactions, and the incorporation of magnetite on the chitosan surface enhanced its removal efficiency. Thermodynamic parameters suggested a spontaneous and exothermic process. Magnetic chitosan proved to be effective in tetracycline removal even after multiple adsorption/desorption cycles.

Summary: The paper presents experimental results on fabricating composite nanostructures consisting of magnetic and nonmagnetic metal oxide nanoparticles using pulsed laser deposition in the presence of a magnetic field. The study found that the difference in the ablation threshold of the initial ablated materials determines the specific methodology for composite fabrication, which could be used in the design of novel magneto-optic and sensor devices. The morphology and structure of the nanostructures obtained were controlled by the magnetic field during deposition.

Summary: To address arsenic contamination in groundwater, hydrated iron oxide gel beads (CS-HFO) and iron manganese oxide gel beads (CS-FMO) adsorbents were prepared. CS-FMO adsorbent showed better adsorption performance due to rich adsorption sites and oxidation capacity. Langmuir model calculations revealed the saturation adsorption of As(V) and As(III) by CS-FMO as 26.65 mg/g and 35.96 mg/g respectively. After 10 cycles of regeneration, CS-HFO and CS-FMO demonstrated excellent sustainable arsenic removal ability. The high selectivity of CS-HFO and CS-FMO adsorbents was confirmed through competing pollutants and fixed-bed column experiments, making them promising for future application in arsenic contamination removal.

Summary: Thermoplastic polymers, or plastics, are essential in our daily life due to their multipurpose, inexpensive and durable nature. Among them, PET, HDPE, and PP are the most commonly used plastics, especially in the packaging industry. However, the increasing production of plastics has resulted in a significant amount of plastic waste, posing a major threat to the environment. The focus now is on improving recycling methods and addressing the quality of recycled plastics and potential contaminations.

Summary: In this study, melt electro written (MEW) scaffolds of poly(e-caprolactone) PCL were decorated with anti-inflammatory yeast-derived peptide for skin wound healing. Thirteen different yeast-derived peptides were screened and analyzed using in vitro and in vivo assays. The selected peptide VLSTSFPPW (VW-9) was conjugated to the MEW scaffolds using carbodiimide (CDI) and thiol chemistry, with and without plasma treatment, as well as by directly mixing the peptide with the polymer before printing. The peptide-modified MEW scaffolds showed improved fibroblast and macrophage penetration and adhesion, increased cell proliferation, and superior anti-inflammatory properties.

Summary: The increasing tendency of population aging is directly correlated with a significant number of associated pathologies. Implantable bone substitutes have proven to be an efficient solution for metabolic bone diseases such as osteoporosis or chronic kidney disease-mineral and bone disorders. This study aimed to develop composite beads with a combination of biopolymers (specifically alginate and guar gum/carboxymethyl guar gum) and ceramics (specifically calcium phosphates). The results showed that the beads based on a higher concentration of guar gum had superior properties for bone tissue repair.

Summary: In this study, a printable biomaterial ink for 3D printing of shape-maintaining hydrogel scaffolds was developed. The ink was composed of tyramine-modified hyaluronic acid (HA-Tyr) and gelatin methacrylate (GelMA), and was dually cross-linked. By adjusting the polymer ratios, a stable hydrogel with varying responses was produced, offering precision and flexibility in 3D printing. The ink exhibited shearthinning behavior and high swelling capacity, making it an ideal candidate for soft tissue matrices with ECM-like characteristics and biocompatibility.

Summary: This review aims to evaluate the antioxidant properties of gellan and guar gums in wound healing. It is found that wound-healing dressings based on gellan gum possess significant antioxidant properties, while the antioxidant properties of guar gum are often overlooked, despite their potential in improving wound healing outcomes. Further research is needed to develop customized wound dressings that can scavenge excess reactive oxygen species, especially in clinical practice.
