Summary: The present study focuses on fabricating electrospun nano fibrous membranes (ENMs) from the blend of polycaprolactone (PCL), gelatin (GEL) and chitosan (CHI) to achieve superior mechanical strength and water flux. The ENMs showed significant changes in morphology, hydrophilicity, porosity, mechanical and thermal stability with different blending compositions. The efficiency of ENMs in filtration applications was evaluated using methylene blue (MB) based model effluent and wastewater, showing high efficiency for MB removal and reduction of physicochemical parameters of wastewater.

Summary: The mechanical, barrier, and thermal properties of biodegradable films composed of gelatin/chitosan blends with and without betel leaf ethanolic extract (BLEE) were investigated. The addition of BLEE improved the elasticity and heat-seal ability of the films, while the seal ability decreased with increasing chitosan proportion. Films containing 2% BLEE exhibited enhanced ultraviolet and visible light barrier abilities and reduced water vapor permeability. The incorporation of BLEE also led to decreased swelling and water solubility of the films, increased antioxidant and antibacterial activities, and improved thermal stability. Therefore, gelatin/chitosan films containing BLEE could serve as active packaging materials with satisfactory properties.

Summary: Anisotropic diffusion filtering is effective for noise removal and edge preservation but highly dependent on diffusion coefficient and threshold parameter. A new technique with faster convergence rate and image-dependent threshold parameter outperforms traditional models of anisotropic diffusion. Experimental results demonstrate the superiority of the proposed method over traditional anisotropic diffusion models.

Summary: This study uses diffusive permeation tests to clarify the barrier performance of geomembranes against bisphenol A and 1,4-dioxane, and finds that dissolved bisphenol A can be adsorbed on the geomembranes, but does not pass through them during the testing period. In addition, dissolved 1,4-dioxane is not adsorbed on any geomembranes and hardly passes through any of them. Thus, geomembranes exhibit a good barrier performance against these two organic compounds.

Summary: Catalytic membrane based oxidation-filtration processes (AOP-CM) provide an efficient water purification strategy by combining physical separation and chemical oxidation. However, the low efficiency of heterogeneous AOPs in catalytic membranes has hampered the application of AOP-CM. To improve the efficiency, an isoporous AlOx/La2CoMnO6-delta ceramic membrane (IAPCM) with nano-confinement characteristics was prepared. The well-designed pore structure of IAPCM resulted in excellent water permeance and size-exclusion performance. Addition of peroxymonosulfate (PMS) enabled ultrafast degradation of organic micropollutants in the IAPCM system. This work emphasizes the significance of pore structure design for high-performance AOP-CM processes.

Summary: In this study, pure and transition metal ions (Cu)-doped V2O5 nanosheets were synthesized and investigated as photocatalysts for the degradation of organic pollutants. The doped nanosheets showed improved efficiency for degrading methyl blue and rhodamine B under visible light. The incorporation of Cu dopant ions improved catalytic efficacy by separating charge carriers and facilitating their movement. The smaller crystalline size and increased specific surface area of the doped nanosheets also enhanced their photocatalytic activity.

Summary: Engineered nanomaterials (ENMs) have been introduced into the market for various applications. The synthesis of new generations of ENMs is now considering environmental, economic, and social criteria alongside technical aspects for sustainability. Therefore, it is crucial to identify the appropriate criteria for ENM synthesis as the technologies move from laboratory to pilot and full-scale production. This study adopts a fuzzy-Delphi methodology to identify the main criteria and sub-criteria for sustainable fabrication of ENMs, and assesses the level of consensus among experts on their relative importance. Health and safety risks of equipment and materials, solvent used, and availability of green experts were identified as the most critical criteria.

Summary: Most biomarker testing is currently done in centralized laboratories, but the development of miniaturized, low-cost microdevices is expected to replace these conventional methods and allow for direct transfer of diagnostic results to a patient's smartphone. While biosensor-based approaches show promise for decentralized testing, there are still issues to be resolved for the understanding of different biomarkers. The creation of biosensors is seen as a promising solution to address the demand for quick, affordable analysis techniques in medical diagnostics.
