Summary: The use of fluorescence imaging in tumor detection and resection assistance has become increasingly popular. This study introduces tetraphenyl ethylene (TPE) and phenylboronic acid (PBA) into polyurethane to synthesize a PU-TPE-PBA (PTP) fluorescent emulsion with aggregation-induced emission (AIE) for targeted tumor imaging. The PTP emulsion, with a size of less than 50 nm, shows excellent stability and high fluorescence sensitivity. The PTP nanoparticles can be enriched in tumors and retained for longer periods due to their ability to selectively recognize and bind to sialic acid (SA), which is overexpressed in tumor cells.

Summary: This study investigated the effects of spark plasma sintering (SPS) conditions on microstructure evolution, phase transformation, and mechanical properties of lunar regolith. The results showed that sintering temperature played a dominant role in changing microstructure heterogeneity and densification, while applied pressure enhanced phase transformation and homogeneity during the sintering process. The strength of the sintered samples was approximately 10 times greater than that of typical plain concrete, suggesting the potential of SPS technology for producing property-specific building components on the lunar surface.

Summary: Amorphous TixOy with high surface area has shown higher activity as a photocatalyst in UV light-induced water splitting applications. The molecular titanium alkoxide precursor structure rearranged during hydrolysis, leading to increased connectivity of structure-building units. Upon exposure to UV light, the suspension turned dark corresponding to the reduction of Ti4+ to Ti3+. Temperature-dependent total scattering experiments showed partial ordering in the Ti-O environment below 350 degrees C, with the formation of a distorted anatase core above this temperature.

Summary: In this study, mesoporous polydopamine (mPDA) encapsulation of fluorescent nanodiamonds (FNDs) was demonstrated for efficient functionalization. The mPDA shell could be easily modified with different functional groups such as thiol-terminated methoxy polyethylene glycol (mPEG-SH), hyperbranched polyglycerol (HPG), and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS). The modified PEGylated FND@mPDA particles showed efficient cellular uptake and served as a fluorescent imaging probe for HeLa cells. Moreover, HPG-functionalized FND@mPDA was used for microRNA detection via hybridization, while the increased surface area of the mPDA shell allowed efficient loading of doxorubicin hydrochloride and its enhanced delivery with TPGS modification, resulting in high toxicity to cancer cells.

Summary: This study describes the mechanism of transformation from 2D δ-MnO2 nanosheets to γ-MnO2 nanocone morphology and reveals the role of Fe galvanic exchange reaction in this transition. The mechanistic insights into the morphology/phase transition were obtained through systematic electron microscopy studies, where the effect of local chemical composition and the oxidation state of Mn ions played key roles. This research is of great significance for understanding the growth and morphology/phase transitions of manganese oxide nanostructures, as well as the rational design of nanomaterials.

Summary: Supported metal catalysts with partial encapsulation due to strong metal-support interactions exhibit distinctive structural features that significantly impact their functionalities. The synthesis and characterization of two Pt/TiO2 models revealed differences in morphology and local structure, which influenced their electrochemical activity and stability. Encapsulation by TiO2 resulted in enhanced particle stability but decreased Pt activity due to increased H+ intercalation on titania.
