Summary: While previous studies on the interaction between nanoparticles and biological barriers mainly focus on the static state, this research investigates the fluid dynamics of nanoparticles and their impact on encountering biological hosts. The researchers successfully synthesized badminton-like Fe3O4&mPDA Janus nanoparticles and studied their stable fluid posture and motion characteristics. The results show that these nanoparticles have reduced blood vessel wall encountering frequency and longer blood half-life compared to conventional spherical nanoparticles.

Summary: Gas-phase synthesis techniques offer a scalable approach to production of metal nanoparticles, but directed assembly is challenging due to fast particle diffusion rates. This study explores the use of an electromagnetic-levitation technique to generate metal nanoparticle aggregates with altered fractal properties, competing with random Brownian forces. Ferromagnetic metals form chain-like aggregates, while paramagnetic metals form compact aggregates with higher fractal dimensions.

Summary: Understanding the role of each plasmon decay channel is crucial for studying the plasmon-exciton interaction in nanoscale plexciton hybrids. In this study, we investigate the influence of chemical interface damping (CID) on the plasmon-exciton coupling by using single-particle spectroscopy. Our findings show that CID reduces the plasmon-exciton coupling strength and can be controlled by modifying the nanoparticle's surface.

Summary: Thiolate-protected metal nanoclusters (TPNCs) have garnered significant interest for their stability, precise structure, and physicochemical properties. Through computational studies, strong correlation between metal-sulfur and sulfur-ligand bond dissociation energies has been identified, providing a pathway for predicting TPNC ligand removal energetics. Computational results also shed light on the kinetic favorability of breaking S-R over M-S bonds in certain complexes, aiding in the targeted design of TPNC catalysts.

Summary: In this study, a thiolate (SR)-protected Au-36 Ag-2 (SR)(18) nanocluster with low ligand coverage and a core composed of three icosahedral (I-h) units is reported for efficient catalyzing hydrogen evolution reaction (HER). The Au-36 Ag-2 (SR)(18) exhibits high catalytic activity at lower overpotentials due to its low ligand-to-metal ratio, low-coordinated Au atoms and unfilled superatomic orbitals. This study provides a new strategy for constructing highly active catalysts from inert metals by pursuing atomically precise nanoclusters and controlling their geometrical and electronic structures.

Summary: This study reports a metal-precise rod-shaped Au42(SCH2Ph)32 with a high aspect ratio of the hexagonal-close-packed Au20 kernel, which exhibits intense longitudinal absorption and effective photothermal conversion at low concentrations. The findings demonstrate that Au42 nanorods inherit the longitudinal excitation similar to metallic-state nanorods. This work highlights the potential applications of Au42 nanorods in photothermal converters, biomedical therapy, photoacoustic imaging, and photocatalysis.

Summary: Surfactants play critical roles in various technological applications, but there are limited methods available for quantitatively studying their adsorption at interfaces. In this study, we demonstrate a direct observation of surfactant adsorption using surface-enhanced Raman scattering (SERS). The results are compared with conventional interfacial tension measurements and thermodynamic theory, providing a research platform to explore structure-function relationships and design new surfactant species.

Summary: The doping of nanoparticles with impurities to create silicon nanoclusters has shown limitations for particles smaller than 5 nm due to surface tension. Thermodynamic calculations reveal a critical size for nanoparticles, below which it becomes impossible to introduce impurities. These calculations were applied to various doping scenarios and showed agreement with experimental results in scientific literature.

Summary: In this study, we experimentally demonstrated that heat-dissipation power driven by ferromagnetic resonance (FMR) in superparamagnetic nanoparticles can lead to highly localized incrementation of targeted temperatures. The generated power is extremely high and robustly correlated with the intrinsic material parameters. Additionally, we found that the magnetization-dissipation-driven temperature increments can be reliably manipulated by extremely low strengths of applied AC magnetic fields.

Summary: Anomalous growth rate reduction and composition divergence are observed in m-plane AlGaN grown at low temperature with increasing aluminum flux. Indium surfactant assisted epitaxy (ISAE) significantly mitigates these effects, enabling high-quality AlGaN growth at 565°C. The phenomena are attributed to the loss of nitrogen and gallium due to aluminum adatoms site-blocking effects, and can be reduced by TEM imaging of high-quality (In)AlGaN/InGaN MQWs.

Summary: Mid-infrared intersubband transitions in strain-balanced m-plane (In)AlxGa1-xN/In0.16Ga0.84N (0.19 <= x <= 0.3) multi-quantum wells are reported for the first time in the range of 3.4-5.1 µm (244-360 meV). The experimental intersubband energies are better reproduced by calculations using the local-density approximation than the Hartree-Fock approximation. The effect of charge density, quantum well width, and barrier alloy composition on the intersubband transition energy is investigated to evaluate the potential of this material for practical device applications.

Summary: Growth of wurtzite ScxAl1-xN (x<0.23) on c-plane GaN at high temperatures alters the lattice constants due to defects, while ScAlN grown below a certain temperature exhibits uniform alloy distribution and reduced defect density. The lattice constant of low-temperature ScAlN varies with composition and can be used to estimate alloy composition. Lattice-matched Sc0.18Al0.82N/GaN multi-quantum wells grown under these conditions show strong near-infrared absorption lines, confirming their advantageous optical and electronic properties.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
