Summary: Researchers have developed a method to selectively assemble mesoporous polymer/carbon on zeolite nanocrystals, creating exotic hierarchical nanostructures with diverse surface geometries. The resulting heterostructures exhibit anisotropic surface wettability and amphiphilic properties upon carbonization. These structures show superior catalytic performance in shape-selective hydrogenation reactions, yielding nearly 100% yield of amine products. The study provides a pathway for the rational construction of hierarchically porous heterostructures with specific physical and chemical characteristics for diverse applications.

Summary: This article systematically reviews the use of silica nanoparticles (Si-NPs) in polymer nanocomposites (NCs) and the role of NPs self-assembly in determining the final material properties. The dispersion and distribution of NPs, as well as the functionalization strategies of Si-NPs, are discussed. The self-organization of Si-NPs and Si-HNPs in polymer matrices and their effects on functional material properties are evaluated.

Summary: Functional mesoporous carbonaceous nanomaterials with large pores have wide accessibility and can transport chemicals efficiently in various fields including biomedical applications, gas separation, catalysis, sensing, and energy storage and conversion. The assembly of monomicelles, composed of block copolymers/surfactants and precursor species, has been used to control the nanostructure and mesoporosity of carbonaceous nanomaterials. This method allows for a high degree of control over the final product's structure, making it possible to shape the nanomaterial into unique nanostructures that are otherwise difficult to synthesize using conventional templating methods.

Summary: The study introduces a unique evaporation-induced self-assembly (EISA) strategy for four different silica nanoparticle systems obtained through peptide functionalization of the particle surface. The research shows that this EISA-based approach provides new possibilities for the design of future advanced drug delivery systems, engineered hierarchical sorbents, and nanocatalyst assemblies.

Summary: The field of advanced nanotechnology offers a wide range of nanotheranostics for treating malignant tumors. Among them, Mesoporous Silica Nanoparticles (MSNs) combined with upconversion nanoparticles have gained prominence in biomedicine research due to their remarkable properties in drug targeting, bio-imaging, and photodynamic/photothermal therapy. MSNs have versatile pore sizes, high drug loading efficiency, and can be functionalized to enhance their applicability. This article focuses on MSN-based hybrid nanotheranostics and their designing strategies, characterization, applications, efficacy, limitations, biotoxicity, as well as current challenges and future perspectives.

Summary: Mesoporous silica nanoparticles (MSN) are potential drug carriers with high drug loading capacity and degradability under biologically relevant conditions. Dissolution studies of MCM-48 MSN in the presence of proteins show that protein concentration affects the kinetics of dissolution and leads to the formation of core-shell structured particles. The results suggest that MSN dissolution kinetics is faster under typical in vitro conditions compared to full serum conditions.

Summary: We report on the fabrication of three-dimensional hierarchical core-satellite SiO2@monomicelle spherical superstructures through a previously unexplored monomicelle interfacial super-assembly route. The ultrathin single layer of monomicelle subunits with hexagon-like regular discontinuous distribution on solid spherical interfaces can be achieved, and the number of monomicelles on colloidal SiO2 interfaces can be quantitatively controlled. This strategy provides a controllable way for building multiscale hierarchical regular micro- and/or macroscale materials and devices.

Summary: This study uses a coarse-grained model and molecular dynamics simulations to investigate the formation of mesoporous silica nanomaterials. By simulating the effects of surfactants and spacers at different concentrations in the system, rapid screening of pore structures is demonstrated, followed by detailed analyses of mesoporous silica loading by reconstructing atomic structures.
