Summary: The proposed study demonstrates that increasing the weight percentage of nano- and micro-TiC hard particles significantly improves the hardness, impact, creep, and tensile strength of the composite material. However, when the ratio of these particles exceeds a certain threshold, it leads to agglomeration and air bubble formation, resulting in a decrease in these properties.

Summary: The extensive use of non-biodegradable plastic products has caused significant environmental issues. Biodegradable polymers offer a solution but face challenges, which researchers are addressing by incorporating bentonite clay into polymeric matrices. However, achieving complete dispersion of nanoclays remains a challenge. Various methods are used to prepare polymer-clay nanocomposites for versatile industrial applications. Combining bentonite clay with other fillers can reduce production costs. This work reviews the development, challenges, and future directions of bentonite clay-based composites with biodegradable polymers.

Summary: A hybrid architecture (LDH@PZE-Fe) was synthesized for flame retardant epoxy resin through intercalation by surfactant and interfacial modification by ferric decorated and amino groups-containing polyphosphazene (PZE). The introduction of 2.5 wt% LDH@PZE-Fe enabled the EP/LDH@PZE-Fe composite to achieve UL-94 V-0 rating with a LOI value of 27.5%. The superior flame retardancy of EP/LDH@PZE-Fe was attributed to its combined action in both condensed and gaseous phases. Additionally, EP/LDH@PZE-Fe showed satisfactory impact strength and enhanced glass transition temperature due to good compatibility with EP matrix.

Summary: Nanocrysatalline copper ferrite exhibits distinct photocatalytic properties, but suffers from high recombination rate of photogenerated electrons and holes due to its narrow bandgap. This study demonstrates that Al3+ doping can reduce the recombination rate and enhance the availability of charge carriers in doped CuFe2-xAlxO4 nanoparticles. Doping with Al3+ leads to a decrease in lattice parameter and increased sintering and crystallite size. However, the surface morphology becomes more homogeneous with a narrower size distribution. The optical properties also show a decrease in photoluminescence signal, indicating a lower recombination rate. Therefore, Al3+ doping increases transition time and improves the efficiency of charge carriers for potential photocatalytic applications.

Summary: In this study, polymer-based synthetic receptors incorporating Ag-ZnS microspheres in molecularly imprinted poly(methacrylic acid-co-ethylene glycol dimethacrylate) (MIPs) were designed for the gravimetric detection of human serum albumin (HSA). The MIPs with a methacrylic acid and ethylene glycol dimethacrylate volume ratio of 3:2 exhibited enhanced HSA sensitivity in the concentration range of 5-200 ng/mL. The quartz crystal microbalance (QCM) based gravimetric sensors achieved a remarkably low limit of detection (LOD = 0.364 ng/mL). The Ag-ZnS@MIPs/QCM sensors showed high selectivity for HSA compared to other proteins. Therefore, the gravimetric quantification of HSA enables a highly sensitive, selective, and label-free detection mechanism with a limit of quantification down to 1.1 ng/mL.

Summary: Amberlite IRN-78 resin with iron was used as a hybrid resin for silica removal from borated water in nuclear power plants. The hybrid resin contained 0.84 wt % iron compounds. In batch experiments, 1 g of the hybrid resin removed 60 mg silica from 1 ppm borated water in 120 min. The efficiency of the hybrid material depended on resin quantity, silica concentration, and pH, and Freundlich and Temkin isothermal adsorption played dominant roles.
