Summary: Sophorolipids are surface-active glycolipids produced by non-pathogenic yeast species and have extensive industrial applications due to their unique physicochemical properties. Compared to chemically synthesized surfactants, sophorolipids are less toxic, more environmentally friendly, biodegradable, and exhibit robustness for industrial applications. They also possess low critical micelle concentrations, reduced interfacial surface tension, and the ability to dissolve non-polar components. The article highlights the utilization of these properties, discusses the advantages and disadvantages of sophorolipids, and explores their potential commercial applications in real-world scenarios. The review also compares biosurfactants with man-made equivalents and provides insights for manufacturing natural or green surfactants with innovative qualities.

Summary: 3-D bioprinting is a novel approach used to promote skin regeneration after chronic wounds and injuries. A novel bioink composed of PEO-CS-PMMA laden with Nicotinamide and human dermal fibroblast was synthesized successfully. The bioink was characterized in terms of swelling, structure confirmation, morphology, thermal properties, 3-D bioprinting, rheology, and DNA interaction. The addition of PEO (5.0%) improved the self-healing and printability of the bioink for producing skin tissue constructs.

Summary: With the advancement in 3D bioprinting technology, the design of complex and physiologically relevant 3D environments through cell culture methods has become possible. The choice of bioink and bioprinting process is crucial and depends on factors such as material properties, biological interaction, gelation, and viscosity. The foundation of 3D bioprinting lies in the precise layer-by-layer implantation of biological elements onto biofabricated 3D structures, with three basic strategies being used: autonomous self-assembly, micro tissue building blocks, and biomimicry. However, there are still obstacles to overcome before functional tissues can be effectively produced and used in clinical settings, requiring a better understanding of bioink materials and the ability to reproduce intricate 3D structures mimicking biology and physiology.

Summary: Mangroves provide ecosystem services, including carbon sequestration, biodiversity conservation, and livelihood support. Despite being threatened by toxic contaminants like heavy metals, mangroves have the potential to survive in saline environments and absorb pollutants. This study explores the dynamics of heavy metal levels in mangrove soil, their absorption, accumulation, and transport. It also highlights the potential of mangrove species in removing heavy metals from marine and coastal environments. The review concludes that mangroves can clean up contaminated water, soil, and sediments through phytoremediation, particularly through root absorption with limited upward translocation. Promoting biodiversity conservation and coastal stability is recommended as an environmentally friendly and potentially cost-effective approach.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
