Summary: This paper investigated the material properties of polypropylene (PP) nanocomposites filled with multi-walled carbon nanotubes (MWCNTs) and found that the addition of MWCNTs affects the melt shear viscosity, specific volume, thermal conductivity, mechanical properties, and electrical properties of the materials. The study revealed that increasing MWCNT loading results in higher melt shear viscosity, lower specific volume, thermal conductivity below 0.35 W/m·K, and the nanocomposite becomes electrically conductive at 3 wt.% loading.

Summary: In this study, the relationship between the morphology of immiscible blends containing polymer hybrid particles and extensional rheological properties was investigated. The length of polymer brushes grafted from graphene oxide particles (GO) affected the extensional rheological properties, with longer brushes leading to decreased elongational viscosity at low rates and increased viscosity at high rates. The findings suggest that polymer brush length plays a significant role in the coalescence and formation of elongated domains.

Summary: The dual-epoxide modification of ZrP nanoplatelets results in the formation of ZrP-g-PMMA nanocomposites with different polymer brush structures. The modification reduces the surface energy of ZrP and improves the configurational entropy of grafted polymer chains, allowing the penetration of matrix PMMA chains into the grafted brush layer. The rheological behavior of the nanocomposites can be tuned by adjusting the loading of nanoplatelets or the grafting characteristics at the interface between ZrP and PMMA matrix.

Summary: It has been found that the mechanical properties of thermoplastic semi-crystalline polyimides can be enhanced by a strong structural ordering near single-walled carbon nanotubes (SWCNTs). In this study, a comparative analysis of computer simulations and experimental measurements was performed to investigate the rheological properties of nanocomposites based on thermoplastic semi-crystalline polyimide R-BAPB synthesized with SWCNTs. The results show that the viscosity of SWCNT-filled R-BAPB increases in the melt state due to the structural ordering near SWCNTs. Additionally, the orientation of polyimide chains near the SWCNT surface leads to anisotropic rheological properties and improved mechanical characteristics of the nanocomposites in the glassy state.

Summary: This paper describes the preparation of metallocene polypropylene (mPP) composites filled with carbon nanotubes (CNTs) using a twin-screw extruder. The crystallization behavior, mechanical properties, and rheological behavior of the composites were characterized. The results showed that the addition of CNTs improved the crystallizability of mPP and increased the initial crystallization temperature and crystallization temperature. The yield stress and elastic modulus also increased with increasing CNTs concentration. SEM images revealed better dispersion and adhesion of CNTs in the polymer matrix. Rotational rheometer results indicated increased interactions between CNTs and mPP.

Summary: This study aims to investigate the effects and mechanisms of CNT length, diameter, and functional groups on the rheological behaviors of cementitious composites. The results show that the addition of CNTs results in a decrease in flow index and an increase in critical shear rate. CNTs with sub-micrometer length and small diameter enhance the yield stress and reduce the viscosity of cementitious composites. The influence of CNT functional groups on the viscosity depends on their water absorption and dispersion properties. The adsorption and entanglement effects of CNTs, related to their length, diameter, and functional groups, play a crucial role in the rheological behaviors of cementitious composites.

Summary: Recently, MXene-based wearable hydrogels have become promising candidates for epidermal sensors due to their softness and unique properties. However, it is challenging to achieve reliable sensing performance and prolonged service life due to MXene oxidation in water-containing hydrogels. To address this issue, catechol-functionalized poly(vinyl alcohol) (PVA-CA)-based hydrogels are proposed to inhibit MXene oxidation, resulting in rapid self-healing and superior strain sensing behaviors. The PVA-CA-MXene hydrogel demonstrates potential for real-time motion monitoring and accurate signal classification using deep learning models.

The kinetic and isothermal examinations showed that the adsorption of Pb2+ followed pseudo 2nd order and Langmuir models. Furthermore, the optimized sample demonstrated superior adsorption selectivity for Pb2+ ions in a multi-metallic system compared to other ions.

Summary: To increase the capacitance of an inorganic electrode material, CoFe-layered double hydroxide (LDH) was grafted onto the surface of hexagonal-flower-like NiCo2O4. Various composites with different Co/Fe ratios were grown directly on Ni foam using the hydrothermal method. The composite with a Co/Fe molar ratio of 1:2 (NiCo2O4 @Co1Fe2-LDH) exhibited the best electrochemical performance, with a specific capacitance of 2595 F g-1 at a current density of 1 A g-1. The composite prevented aggregation of CoFe-LDH, leading to high specific capacitance and good stability. The electrode was used in a packaging asymmetric capacitor, resulting in a maximum energy density of 27.33 Wh kg-1 at a power density of 800 W kg-1 and an excellent capacitive retention of 96% even after 5000 charge-discharge cycles.

An equation is proposed to determine the strength of HNT composites with an imperfect interphase and an HNT network. The relationships between B and Lc, HNT size, and percolation start are analyzed. The lowest Lc, lowest percolation start point, slimmest and longest HNTs, and highest interfacial shear strength yielded the highest B values and the toughest samples.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
