Summary: The synthesis of carbon black/silica colloidal composites using a surface adsorption methodology was performed in this study, with the use of a unique surfactant for enhancing surface activity. Characterization studies, including morphological analysis, chemical extraction study, and energy dispersive x-ray analysis, were conducted to validate the results. The adaptation of a simple, low-cost, and environmentally friendly process for promoting the synthesis of CB/silica composite material was encouraged based on the uniform distribution of silica in the composite aggregates.

Summary: Water-soluble nonionic surfactant, C12E5, was found to spontaneously bloom to the surface of hydrophobic polyisoprenes, generating hydrophilic surfaces. The depth profiles were quantified using neutron reflectometry (NR) and the surface properties were characterized using contact angle analysis and atomic force microscopy (AFM). Despite resistance to dissolution, water exposure altered the wettability of the surface, revealing two distinct populations of surfactant on the polyisoprene film surface, with one population being laterally inhomogeneous.

Summary: Mesoporous silica was successfully synthesized using geothermal water from the Onuma Geothermal Power Plant in Japan for the first time. Cetyltrimethylammonium bromide (CTAB) was used as an organic template for the synthesis, resulting in efficient recovery of supersaturated silicic acid from the geothermal water. The monosilicic acid in geothermal water plays a crucial role in the formation of mesoporous silica, which can contribute to preventing silica scale formation in geothermal power plant piping systems and serve as an industrial resource.

Summary: The adsorption of polymers on the surface of mesoporous silica nanoparticles allows for versatile adhesion between hydrogels or biological tissues. However, when the number of nanoparticles deposited exceeds a critical threshold, thick multilayers form at the interface and decrease the adhesion strength. To overcome this limitation, spherical aggregates were prepared by spray drying, resulting in stronger cohesion between nanoparticles. The adhesion energy with these supraballs was significantly enhanced compared to nanoparticles, and corrugated interfaces stabilized by supraballs contributed to the largest adhesion enhancement.

Summary: In this study, L-lysine modified mesoporous silica nanoparticles (MS@Lys NPs) were synthesized for the delivery of the anticancer drug curcumin (Cur) to cancer cells. The functionalization of L-lysine groups onto the mesopore channel surfaces of MS@GPTS NPs was achieved through a ring-opening reaction. The structural properties of MS@Lys NPs were examined using various instrumental techniques. The drug loading and pH-responsive drug delivery behavior of MS@Lys NPs were investigated using curcumin as a model drug, and their cytocompatibility and cell uptake behavior were evaluated using MDA-MB-231 cells. The results suggest that MS@Lys NPs have potential for pH-responsive drug delivery in cancer therapy.

Summary: The study reveals that mesoporous silica nanoparticles (MSNs) are formed at the interface of the biphasic water-surfactant-triethanolamine-tetraalkoxysilane (TAOS) quaternary system. The hydrophobic TAOS undergoes spontaneous microemulsification to generate microdroplets and direct micelles, which determine the size of the particles and pores. The dendritic morphology with conical pores is identified as an intermediate species that transforms into regular MSNs as the microemulsion collapses due to continuous consumption of TAOS. The significant impact of microemulsion on the growth mechanism is thoroughly investigated and termed tetraalkoxysilane-assisted self-emulsification templating.

Summary: A two-photon excited ratiometric fluorescent pH sensor was developed by combining L-cysteine-protected AuNCs (Cys@AuNCs) with fluorescein isothiocyanate (FITC). The sensor showed a large dynamic range for pH measurement and had potential for sensitive quantitation of pH in living cells under two-photon excitation. In addition, the synthesized Cys@AuNCs exhibited excellent photoactivated peroxidase-like activity, promising for rapid colorimetric biosensing and control of catalytic reactions by photostimulation.

Summary: In the past several decades, noble metal nanoclusters (NMNCs) have gained development as an emerging class of luminescent materials due to their superior photo-stability and biocompatibility. However, their luminous quantum yield is relatively low and the physical origin of the bright photoluminescence (PL) of NMNCs remains unclear, limiting their practical application. This mini-review comprehensively introduced the effect of each component (metal core, ligand shell, and interfacial water) on the PL properties of NMNCs and proposed a model in which structural water molecules dominate the p-band intermediate state to give a unified understanding on the PL mechanism of NMNCs and future developments.

Summary: The controversy over the emission center of metal nanoclusters has been ongoing. In this study, gold nanoclusters with multiple emission peaks were synthesized using aggregation-induced emission and a ligand-exchange strategy. The photoluminescence is independent of the excitation wavelength and is from supramolecular clusters formed by the assembly of functional groups on the nanoconfined surface of an individual gold nanocluster.

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.
