Summary: In this study, we demonstrate a counterintuitive interplay between modes in the plasmonic system of gold nanorods, wherein energy transfers from the lower-energy longitudinal mode to the higher-energy transverse mode. The opening of this energy transfer channel is enabled by an energy upconversion process with the longitudinal mode, and the solvent environment plays a critical role. The findings provide insights into the elusive intermode interplay in plasmonic systems and offer strategies to harness hot electrons for plasmon-mediated applications.

Summary: This study demonstrates a counterintuitive interplay between different modes in the plasmonic system of gold nanorods, where energy is transferred from the lower-energy longitudinal mode to the higher-energy transverse mode. The solvent environment plays a critical role in enabling this energy transfer. Control experiments using ultrafast spectroscopy provide verification and manipulation of this phenomenon, as well as addressing the subtle intermode dynamic screening effect in this unary plasmonic system.

Summary: This study presents a simple method for fabricating Au@Pd bimetallic branched nanoparticles, which allow for tunable optical response, using polyallylamine-stabilized branched AuNPs as template cores for Pd overgrowth. The concentration of PdCl4(2-) and ascorbic acid (AA) can be manipulated to alter the palladium content, enabling the growth of a Pd shell up to approximately 2 nm thick. The presence of palladium on the surface of gold nanoparticles enhances their catalytic properties, as demonstrated through a comparison of nanoenzymatic activity.

Summary: Researchers synthesized a novel Pt(II) metallacycle (Pt1110) that can be activated with a 980 nm laser for photodiagnosis/treatment in deep tissue. Pt1110 showed significantly improved photothermal conversion and O-1(2) generation compared to the ligand itself 1, and it was capable of light-induced sterilization under safe laser irradiation. Pt1110 also had little to no toxicity to cells. When incorporated into liposomes, Pt1110 NPs effectively promoted wound healing in infection and keratitis models upon laser irradiation, observed by NIR-II fluorescence imaging. This novel metal-coordinated supramolecular material has the potential to be a universal platform for phototherapy in deep tissue.

Summary: Membrane modification with polydopamine can enhance membrane selectivity and compatibility. This study investigated the polymerization mechanism of dopamine on porous membranes and its impact on membrane performance. The results showed that polydopamine coating slightly reduced the membrane's pore size and formed aggregates on both the membrane surface and inner pores. The membrane's pore size significantly influenced the penetration and polymerization of dopamine.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
