Summary: Adsorption technology is a promising method for removing pollutants in fluids, and Ti-MOFs are widely used as efficient adsorbents. However, the use of Ti-MOFs with different morphologies for dye removal has not been reported. In this study, three kinds of Ti-MOFs with different morphologies were prepared and tested for adsorbing different dyes. It was found that the truncated octahedron Ti-MOFs showed the best removal efficiency for the cationic dye methylene blue. The adsorption process was exothermic and followed a pseudo-second-order/Freundlich isotherm model. The results also showed that the adsorption performance was dependent on the facet orientation, with truncated octahedron Ti-MOFs exhibiting the highest adsorption capacity among the three morphologies. This research provides a highly efficient adsorbent for industrial dye wastewater remediation.

Summary: It was found that various carcinogenic dyes in water bodies are difficult to degrade due to their stability, causing extended pollution. To tackle this issue, two metal-organic framework materials (MOF 1 and MOF 2) were synthesized and characterized. Based on their structural characteristics, two cationic MOF material skeletons (MOFs I and II) were designed and obtained through calcination to remove free components. The adsorption capacity of MOF I for Congo Red was found to be 2922.8 mg g-1. The adsorption process follows the pseudo-second-order kinetic model and Freundlich isotherm model. Electrostatic interactions and hydrogen bond were identified as the main factors promoting the adsorption of Congo Red dyes on MOF I. Therefore, MOFs I and II are considered as promising adsorption materials for efficient removal of hazardous organic aromatic pollutants.

Summary: This work proposed a method to achieve the optimum design of a corona ring on a 132 kV composite non-ceramic insulator string using two optimization methods: the Imperialist Competitive Algorithm (ICA) and Grey Wolf Optimisation (GWO). The electric field distribution in the model geometry was obtained by finite element analysis of a composite non-ceramic insulator string with and without a corona ring. The results showed that the minimum electric field magnitude along the insulator string was lower using optimization techniques compared to without using optimization techniques by between 3.724% and 3.827%.

Summary: Polybutylene terephthalate (PBT) hybrid nanocomposites reinforced with synthetic wollastonite nano-fibers (SWN) and graphene oxide (GO) were prepared by melt compounding. The study investigated the effect of GO content on the properties of PBT/SWN/GO nanocomposites. The hybridization of SWN and GO improved the mechanical, thermal, and tribological properties, but the poor interaction between GO and PBT matrix limited the reinforcing effect of SWN.

Summary: In this study, biocomposite films were prepared from biodegradable polylactic acid (PLA), silica, and empty fruit bunch fiber (EFB), and their properties for food packaging were investigated. The addition of silica improved the thermal properties of the PLA composite film but reduced its light transmission. The use of TEFB fibers improved the interfacial bonding force between natural fillers and PLA, and adding organic silica increased the water vapor diffusion (WVP) while inorganic silica reduced the WVP of the composite film. The PLA/EFB composite films reinforced with natural fiber and silica showed better packaging performance than existing polyethylene films.

Summary: Polyoxymethylene (POM) nanocomposites reinforced with synthetic wollastonite nanofibers (SWN) showed improved mechanical, thermal, and flammability properties as the aspect ratio of SWN increased. Higher aspect ratio SWN resulted in increased tensile strength, Young's modulus, and impact strength in POM nanocomposites. However, lower aspect ratio SWN performed better in flame retardancy, with delayed time to ignition and decreased peak heat release rate.
