Summary: Bimetallic Au@Pt/Au NPs with triple-layered core-shell structure were successfully prepared and characterized. The single Au@Pt/Au NPs exhibited size-dependent properties for vol-tametric response and electron-transfer rate, and showed excellent electrocatalytic activity, long-term tolerance, and anti-toxicity compared with traditional Pt catalyst. This work provides new insight into conventional electrocatalysis and offers a platform for designing entirely new catalysts at single NPs level.

Summary: By changing the shape and composition, the plasmon-enhanced optical properties of nanomaterials can be controlled. In this study, Au/PbS/Au nanostars with multiple tips were synthesized using a gentle approach, and their SERS activity, SHG, and photocatalytic performance were explored. The Au/PbS/Au nanostars exhibited broad spectral responses and enhanced local electric fields, leading to improved SERS activity and photocatalytic efficiency.

Summary: The study investigated the causes of single-molecule fluorescence spectral heterogeneities and found that they were influenced by structural rigidity and environmental changes. Factors such as system noise uncertainty and environmental polarity were ruled out. The rotational flexibility of N,N-dialkylated groups was found to contribute to the heterogeneities.

Summary: Heterobimetallic single chain nanoparticles were synthesized and used as recyclable homogenous catalysts. These nanoparticles consist of two metals, Au(i) and Y(iii), with different functionalities, enhancing the flexibility of the catalytic system. The catalytic activity of Au(i)/Y(iii)-SCNPs as homogenous and recyclable catalysts was demonstrated in the hydroamination of aminoalkynes, bridging the gap between homogeneous and heterogeneous catalysis.

Summary: In this study, atomically precise gold nanoclusters are embedded in natural polysaccharide carrageenan to create a hydrogel platform for single near-infrared light-triggered photothermal and photodynamic antibacterial therapy. The embedded nanoclusters exhibit thermal effects and singlet oxygen generation under near-infrared light, enabling rapid elimination of bacteria. The carrageenan endows the hydrogel with gelation characteristics and wound microenvironment regulation, promoting wound healing. The hydrogel demonstrates excellent antibacterial activity and biocompatibility, offering an alternative strategy for battling bacterial infections without antibiotics.

Summary: The study investigates the effects of shape and interaction parameters on the plasmonic properties of Au-Cu alloy nanoparticles, revealing a significant shift of the plasmon resonance peak from visible to infrared regions, along with linear and exponential decay variations. The observations support the universal exponential decay behavior and establish correlations between shape and interaction parameters with aspect ratio and interparticle separation, verifying the model's applicability universally.

Summary: This study demonstrates that coating single crystalline Ag nanoparticles with a thin polycrystalline Au layer weakens the particles and leads to more homogeneous deformation. The research further reveals that particle weakening at low strains is attributed to the plasticity confinement in the polycrystalline shell, while at higher strains it is initiated by the plasticity within the Ag core.

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.
