Summary: The study introduces a new method for evaluating pore structures in carbon materials, using high-pressure CO2 adsorption isotherms to determine the pore size distribution in both micro- and mesopores. By utilizing Monte Carlo simulations and meso-canonical ensemble methods, capillary condensation transitions in mesopores were successfully predicted, demonstrating the feasibility of the technique in micro-mesoporous carbon materials.

Summary: The study synthesized porous methacrylate-modified FDU-12/poly(methyl methacrylate) and amine-modified FDU-12/Nylon 6 nanocomposites, which were applied as novel adsorbents for removing Pb(II) from aqueous media. Results showed that the adsorption process followed the pseudo-second-order kinetic model, and the Langmuir isotherm provided the best fit for the equilibrium data with maximum adsorption capacities of 99.0 and 94.3 mg g(-1) for the two adsorbents, respectively.

Summary: Cementitious materials have a complex pore structure, with microscale pores having a significant impact on material strength. The influence function shows that the effect of pores on strength increases with pore size, particularly at larger sizes. Microscale pores should be avoided to improve material strength.

Summary: Mesoporous graphitic carbon nitride (GCN-500) effectively degrades tetracycline (TC) antibiotic under solar light irradiation, exhibiting a 2.13 times improvement in photoactivity compared to bulk GCN. The enhanced photoactivity is attributed to its high porosity, optical absorption properties, and efficient charge carrier separation.

Summary: A programmable shear-induced dynamic assembly approach was developed to synthesize mesoporous carbon nanospheres with tunable core-shell structures and gradient pore systems. The micelle structures in the system can be adjusted by changing shear force and a programmatically proceeded synthesis process results in intelligent assembly of multimodal mesostructures. The resultant carbon nanospheres exhibit high capacity and ultra-long cyclic life for sodium-ion storage, showing potential for innovative applications.

Summary: The compressional behavior of i-AlCuFe quasicrystal under high pressure conditions was investigated, showing continuous decrease in d-spacing with pressure but without structural phase transformations or amorphization. The study helps expand our understanding of the stability of icosahedrite at very high pressure and supports the evidence of natural quasicrystals surviving in the history of the Solar System.

Summary: The carbon concentration in the upper mantle controls melt formation and volatile outflux, with heterogeneous distribution suggesting varying extents of mantle metasomatism. The depth of melt formation in the upper mantle is positively correlated with carbon enrichment, indicating a key role of carbon in driving plate tectonics.

Summary: Through the analysis of mantle xenoliths and thermodynamic modeling, this study reveals the stable conditions for the pargasite-phlogopite assemblage in a harzburgite matrix and the impact of K-Na-OH rich fluids on the ultramafic system. Understanding the species equilibrium in the mantle under high temperature and pressure conditions, a model is proposed to explain the reduced oxygen fugacity in a peridotite metasomatized ambient.

Summary: This experimental study documents the formation of strongly ultrabasic and ultracalcic melts through the interaction of melilititic and basanitic melts with calcite. The results indicate that carbonate assimilation by natural ultrabasic melts can occur at shallow depths and result in lime-rich melt compositions. The study also highlights the limitations of using olivine composition to infer the characteristics of the melt.

Summary: This study reports the first natural occurrence of Fe-bearing aluminous bridgmanite in the Katol L6 chondrite, with a composition closely matching those synthesized in high-pressure experiments. The mineral coexists with majorite and metal-sulfide intergrowths, and has a significantly higher Fe3+/Sigma Fe ratio compared to coexisting majorite, in agreement with experimental studies. Textural observations and comparisons with laboratory experiments suggest that the Katol bridgmanite formed directly from chondritic melt generated by a shock event at pressures of around 23 to 25 gigapascals.
