Summary: This study directly observed the formation of ultra-small Au clusters in the presence of PAA-Na, which coalesce to form nanocrystals corresponding to the size of Au-13 cluster. Molecular dynamics simulations revealed that gold has greater stability in an aqueous environment compared to other cluster sizes, providing atomistic details of growth by cluster coalescence.

Summary: The coupling of W18O49 and Au in W18O49-Au heterostructures enhanced the light absorption and carrier separation ability of this dual-plasmonic system, leading to highly enhanced performance for nitrophenol hydrogenation. The rate constant of W18O49-Au reached 0.2044 min(-1), which was 12 and 102 times higher than that of Au and W18O49, respectively. The hot electron injection process from W18O49 to Au, demonstrated by single-particle photoluminescence (PL) spectroscopy, was found to be beneficial for boosting the catalytic performance.

Summary: By analyzing observations from the MMS and ARTEMIS P1 spacecraft, it was found that the terrestrial foreshock is an important source region of ESMHs at 1 au, while some ESMHs come from the upstream undisturbed solar wind. The generation of these ESMHs can be explained by the electron vortex magnetic hole.

Summary: Single-pixel cameras offer a promising alternative to multi-pixel sensors for mid-infrared (MIR) imaging. In this study, a MIR single-photon computational imaging method with a single-element silicon detector is demonstrated, employing nonlinear structured detection and upconversion detection. Advanced algorithms enable MIR image reconstruction under sub-Nyquist sampling and photon-starving illumination. This single-pixel upconversion imaging paradigm provides simplicity, single-photon sensitivity, and room-temperature operation, opening up new possibilities for sensitive imaging at longer infrared wavelengths or terahertz frequencies.

Summary: A series of compounds P1-P4 with terminal alkynyl sites connected to a phosphonium group via different K-conjugated linkers have been synthesized. These compounds are efficient push-pull emitters and exhibit bright fluorescence in blue and near-UV regions. Using P1-P4 as alkynyl ligands, a series of homoleptic bis-alkynyl Au(I) complexes 1-4 were obtained. The complexes show bright phosphorescence and dual emission, with dominant phosphorescence in most cases.

Summary: Plasmon-enhanced electrochemiluminescence (ECL) at the single-nanoparticle (NP) level was investigated using ECL microscopy. An ordered array of gold nanoparticles (Au NPs) was used, allowing for high-throughput characterization and a strong dependence of ECL intensity on Au NP configurations was observed. It was demonstrated that small Au NPs (<40nm) quenched the ECL of Ru(bpy)(3)(2+)-TPrA, while large Au NPs (>80nm) enhanced it due to localized surface plasmon resonance (LSPR). The coupling effect of neighboring Au NPs further increased the ECL intensity. The results were supported by Finite Difference Time Domain (FDTD) simulations. This plasmon-enhanced ECL microscopy provides a reliable tool for screening electrocatalytic activity at the single-particle level.

Summary: Understanding the nanoscale mechanism of calcium silicate hydrate (C-S-H) transformation during cement hydration is crucial for achieving desired properties in concrete. Through multimodal transmission electron microscopy (TEM), this study reveals that C-S-H rapidly nucleates at boundaries and then grows, with the development of C-S-H fibrils categorized into needle elongation and texture densification stages. The growth rate of C-S-H needles is estimated to be 7 nm/min, accompanied by a decrease in intrinsic porosity and thickening of C-S-H lamella. Electron diffraction analysis demonstrates the homogenization of C-S-H throughout hydration. These findings enhance our understanding of hydration mechanisms at a fundamental level.

Summary: pH-responsive capsules were developed through interfacial photo-cross-linking with thymine-functionalized parent polymer particles. The hydrophilicity of the capsule polymers played a critical role in achieving controlled release of encapsulated molecules. P(St-2VP-VBT) showed pH-responsive release behavior, with release under basic conditions due to thymine deprotonation and increased hydrophilicity, and also responded to acidic pH due to pyridine protonation. Dual pH-responsive capsules were successfully created using P(St-2VP-VBT) particles.

Summary: Researchers have achieved near-unity singlet fission by assembling Pc chromophores on nanosized CdTe quantum dots, leading to suppression of triplet-triplet annihilation and efficient light-harvesting. The unique arrangement of Pc on the quantum dots surface plays a key role in realizing the singlet fission, with rapid dissociation of triplet pairs contributing to long-lived triplets.

Summary: This study describes the synthesis of gold nanoclusters functionalized by peptide dendron thiolate ligands to form a hydrogen bonding supramolecular reaction field. The prepared nanoclusters act as efficient photocatalysts for oxidative cyclization, with dynamic transformation of hydrogen bonds between ligands playing a key role in accelerating the reaction. The concept introduced in this work allows for tuning reactivities and selectivities of metal nanocluster catalysts using supramolecular reaction fields created with dendritic thiolate ligands.

Summary: Localized surface plasmon resonance (LSPR)-induced hot-carrier transfer is an attractive option for efficient energy conversion, particularly in the infrared (IR) range. By using femtosecond transient absorption measurements, the researchers observed the dynamics of LSPR-driven hot holes in CuS nanocrystals (NCs) and CuS/CdS hetero nanocrystals (HNCs). In CuS NCs, hot holes relax through multiple pathways, populating two trap states before decaying. In CuS/CdS HNCs, the hot holes are transferred to the CdS phase through plasmon-induced transit hole transfer (PITCT) and relax in a longer timescale. This study provides important insights into controlling LSPR-induced relaxation in semiconductors.
