Summary: The dynamic formation process of SBA-15 using hexane as a swelling agent is investigated through in situ SAXS technique. The micelles transform rapidly from spherical to cylindrical shapes and self-assemble into a hexagonal structure. The growth of SBA-15 involves two distinct processes related to the formation of micelles and superlattices. The methodology developed here holds promise for widespread applications in the in situ X-ray scattering observation of various chemical reaction processes, paving the way for the design and synthesis of complex functional materials.

Summary: The synthesis of mesoporous silica nanoparticles (MSNs) for nanomedicine applications is influenced by various experimental factors and lacks reproducibility. This study used pH measurements and light diffusion monitoring to investigate the early stages of MSNs synthesis. The results revealed two hydrolysis regimes before nanoparticle formation, and the condensation reaction only initiated after silicate-surfactant micelle aggregation. Factors like stirring strength and presence of sodium hydroxide carbonates significantly affected the kinetics and size of MSNs formation, requiring careful control for reproducibility. The study proposed a formation mechanism that emphasized the interplay between chemical and physicochemical processes in this complex system.

Summary: We report a strategy for the synthesis of chiral mesoporous silica nanospheres with molecular-scale-like chirality. The functionalization of micelles with chiral amide gels leads to the growth of molecularly chiral silica sols, which self-assemble into dendritic large mesoporous silica nanospheres with molecular chirality. The resulting chiral mesoporous silica shows abundant large mesopores, high pore volumes, high surface areas, and exhibits notable optical activity. It also displays good chiral stability and exhibits significant inhibition of β-amyloid protein aggregation formation and cytotoxicity.

Summary: Nanopores have various applications in biocatalysis, drug delivery, and sensing devices. The interaction between biomacromolecules and surfaces is influenced by nanopore diameter, which is important for their infiltration into porous materials. We present a novel approach for synthesizing large-pore mesoporous silica thin films (MTF) through supramolecular templating and phase separation using block copolymers. The tunability of pore size distribution is achieved through reversible addition-fragmentation chain transfer (RAFT) polymerization.

Summary: This work presents a programmed stimuli-responsive poly(N-isopropylacrylamide)-carbon dot (PNIPAM-CD) hybrid nanogels for nanotheranostic applications. The hybrid nanogels enhance tumor accumulation and penetration by enlarging their particle size and generating heat and reactive oxygen species (ROS) upon deep-red-light irradiation. The pH-responsive charge reversal and temperature-dependent hydrophilic/hydrophobic conversion characteristics improve cellular internalization. The overexpressed glutathione (GSH) triggers further cleavage of the partially degraded hybrid nanogels for rapid elimination.

Summary: The first organic long persistent luminescence (OLPL) system based on carbon dots (CDs) with a duration of over 1 hour has been developed. The CDs-based system, named m-CDs@CA, can be easily fabricated using a household microwave oven and exhibits long persistent luminescence under ambient conditions and even in aqueous media. The successful composition of CDs and CA, the formation of exciplexes and long-lived charged-separated states were confirmed by various characterizations. Covalent bond formation between CA and CDs was found to play a key role in activating long persistent luminescence and preventing its quenching from oxygen and water. This work provides new insights for the development of rare-earth-free and robust OLPL materials.

Summary: Extensive research has been carried out on multifunctional theranostic agents for cancer treatment. In this study, ferrocene-carbon dot-crosslinked nanoparticles were designed and fabricated for specific and enhanced chemotherapy. These nanoparticles not only inherit the properties of carbon dots but also demonstrate chemodynamic therapy selectively in tumor microenvironment due to the presence of ferrocene. The enlarged particle size of the nanoparticles facilitates their accumulation at tumor sites and results in improved antitumor outcomes. The combination of photothermal therapy and chemodynamic therapy shows a synergistic therapeutic effect. This study provides a facile approach to fabricate multifunctional theranostic nanoplatforms and emphasizes the benefits of synergizing therapeutic modalities for cancer therapy.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
