Summary: Polypropylene (PP)/talc composites are widely used in various industries, but the demand for more efficient and environmentally friendly materials is increasing, leading to the exploration of new reinforcements. Graphene nanoplates (GNP) offer a good alternative due to their ability to enhance properties and optimize processes. This study investigated the effects of adding different weight percentages of GNP to PP/talc composites and found that it led to improvements in various properties such as flow behavior, mechanical strength, and electrical conductivity.

Summary: Both graphene and carbon nanotubes can improve the crosslinking density, reduce rolling resistance, and wet-skid resistance of NR composites. Compared to CNTs, graphene degrades manufacturing safety and cure rate, but exhibits a higher reinforcing effect in terms of tensile strength, modulus, and hardness. Additionally, graphene/NR composites show better aging resistance than CNTs/NR. On the other hand, CNTs can improve manufacturing safety and cure rate, maintain higher tear strength, and provide better tensile fatigue and wear resistance, as well as lowering rolling resistance while maintaining higher wet-skid resistance in comparison to graphene.

Summary: Novel carbon nanostructures, carbon nanobuds and nanoballs, have been successfully synthesized on the surface of graphene using the electrochemical method. Under a certain potential, carbon nanobuds are grown in situ on the surface of graphene, and with the increase of potential, these nanobuds grow into nanoballs and exfoliate from the graphene surface. Graphene undergoes oxidation at higher potentials, resulting in the formation of graphene oxide fragments.

Summary: This study developed a wave absorbing material by loading polyaniline onto the surface of carbon nanotube bundles in Buckypaper and using epoxy resin as the matrix. The research demonstrated that the three-dimensional porous structure of the Buckypaper allows for high content addition of carbon nanotubes and uniform dispersion in the epoxy resin. The addition of polyaniline improved impedance matching and loss mechanisms, as well as the mechanical strength of the material through the interaction between noncovalent bonds and surface electrons.

Summary: The technique for synthesizing poly (methyl methacrylate) (PMMA) using graphene nanoplatelets (GNPs) has been improved to enhance the elastic properties of the polymer. The addition of GNPs at 2 wt% by mass increased compressive strength by 42.7% and Rockwell hardness by 19.9%. The structural changes due to the addition of GNPs were found to be uniquely linked to improvements in elastic parameters of the PMMA/GNPs nanocomposite.

Summary: Considerable amounts of coal fly ash (CFA) are produced annually without proper utilization. Alkali-activated CFA was introduced to prepare ceramics to treat neodymium-contaminated soil, and its effect on the properties of the ceramics was investigated. The alkali activation of CFA led to a desilication reaction and the generation of new phases rich in sodium, enhancing the mechanical properties of the ceramics. The alkali-activated CFA exhibited higher bulk density and homogeneous distribution of Nd ions in the matrix compared to untreated CFA.

Summary: C/C-ZrC-SiC composites with La-doped ZrC-SiC-ZrSi2 coatings containing different La contents were prepared. The ablation behaviors of the composites under oxyacetylene flame were studied, and the effects of La2O3 addition on the microstructure and phase composition evolution were investigated. The results showed that the composites with 15 wt% La2O3 exhibited better ablation resistance due to the formation of a dense oxide layer consisting of m-ZrO2, t-ZrO2, and Zr0.9La0.1O1.95 phases.

Summary: SiO2 interface was introduced into SiCnws/BSAS ceramic to enhance high-temperature electromagnetic absorption. By changing the SiO2 content, the interface structure was tailored, leading to increased polarization loss. The optimized SiCnws/SiO2-BSAS ceramic demonstrated enhanced electromagnetic absorption at 873 K with an effective absorption bandwidth of 4.1 GHz. The electromagnetic absorption mechanism was analyzed from the perspectives of electron transport and space charges. This heterointerface design strategy offers a new method for developing high-temperature electromagnetic absorption materials.

Summary: Lead is commonly used for X/gamma ray shielding and dosage reduction, but improper recycling can lead to serious hazards. On the other hand, recycling lead from high metal content gamma-ray shielding materials can serve as a secondary metal source and contribute to regulated accumulation and environmental protection. This study focuses on the recovery of lead from waste flexible Vinyl-Methyl-Silicone based gamma-ray shielding materials, with analysis of the effects of pyrolysis temperature and heating rate. Optimum conditions resulted in a lead recovery rate of 57.40 wt% at a pyrolysis temperature of 300°C for 15 minutes, producing a solid product consisting mainly of lead and lead oxides.
