Summary: By using the theory of absorbing Markov chains, the mechanisms that control the shapes of crystals with penta-twinned structures were explored. Different types of products, including decahedra, nanorods, and nanowires, were predicted based on the morphology of the seed. The model was validated by comparing the predicted nanowire morphologies with experimental results.

Summary: Ternary plasmon Ag/CuInS2/BiVO4 S-scheme core-shell heterostructures with decahedral morphology were synthesized using hydrothermal, solvothermal, and photodeposition strategies. The combination of these strategies increased the specific surface area and provided sufficient surface-active spots for the photocatalytic reaction. Under visible light irradiation, the photocatalytic degradation rate of plasmon Ag/CuInS2/BiVO4 for Bisphenol A in water was up to 98.8%, with a hydrogen yield of 6.493 mmol h-1, several times higher than that of pristine ones. The quantum efficiency at 420 nm light was 11.3%. Meanwhile, it exhibited a strong inhibitory effect on Escherichia coli and Staphylococcus aureus in water due to the unique broad-spectrum bactericidal effect of Ag nanoparticles and the bactericidal effect of reactive oxygen radicals. The robust photocatalytic performance can be attributed to the particular S-scheme core-shell heterojunction favoring spatial charge separation, the surface plasmon resonance of Ag nanoparticles extending long wavelength light response, and obvious photothermal effect. This study presents a new tactic for manufacturing efficient S-scheme heterojunction photocatalysts for solar energy conversion.

Summary: This study demonstrates the fabrication of Pd-Au asymmetric nanopyramids through seed-mediated growth, showcasing two asymmetric growth modes initiated by symmetry breaking arising from slow reduction kinetics. The manipulation of aspect ratio and tip sharpness of the nanopyramids was achieved by introducing Ag+ ions into the growth solution.

Summary: Using polysaccharide nanocrystals as fillers in biodegradable polyesters can create completely biodegradable nanocomposites. The study found that chitin nanocrystals and cellulose nanocrystals have completely different effects on the crystallization of poly(epsilon-capro-lactone) (PCL). Chitin nanocrystals retard the nucleation and overall crystallization process of PCL, while cellulose nanocrystals promote nucleation and accelerate crystal growth.

Summary: This study presents a method for the facet-controlled synthesis of nanocrystals with an ultrathin shell made of a nearly equimolar RuRhPdPt quaternary alloy, showing greatly enhanced activity toward ethanol oxidation. The core-shell nanocubes demonstrate good thermal and electrochemical stability in terms of both geometrical shape and elemental composition, making them a promising candidate for various thermal and electrochemical reactions. The synthetic approach can potentially be extended to fabricate multimetallic catalysts with enhanced activities.

Summary: Water-soluble nonrare metal Ag-Sn-S nanocrystals (ATS NCs) were synthesized at room temperature using the interfacial nucleation mechanism. The synthesized ATS NCs exhibited a band gap of 2.32 to 2.59 eV, giving them a high redox ability and very high photocatalytic degradation rate. The interfacial regulation of acid protonation on the surface of ATS NCs resulted in more defect states, which improved the photocatalytic oxidation degradation efficiency. The ATS NCs showed potential for practical treatment of large-scale industrial wastewater.

Summary: Lead halide perovskite nanocrystals (LHP NCs) have great potential in optical sources, photovoltaics, and sensor fields. This Perspective summarizes representative attempts to achieve controlled synthesis of LHP NCs. By changing the synthesis method, LHP NCs with kinetic dominance and size tunability can be obtained. Undesired ripening effects can be eliminated, and homogeneous size distribution can be achieved through rational ligand selection and solvent engineering.

Summary: This study establishes a theoretical criterion based on the classical nucleation theory to predict non-reciprocal nucleation using Ag-Cu alloys as examples. It is found that in hypoeutectic alloys, the beta-Cu phase acts as a more effective nucleation substrate for the alpha-Ag phase, while in hypereutectic alloys, the opposite is observed. This non-reciprocal nucleation phenomenon is reflected in the solidification process of the alloys.

Summary: Photocatalytic glass-ceramics with metallic Ag, semiconductor AgBr, and hybrid metal-semiconductor Ag-AgBr nanostructures were synthesized using low-temperature Na+-Ag(+ )ion exchange. The spectral features and photocatalytic performance of the nanostructures in the silicate glass matrix were investigated. Glass-ceramics with hybrid metal-semiconductor nanostructures exhibited one order of magnitude higher photocatalytic activity compared to those with metallic and semiconductor nanostructures. The hybrid metal-semiconductor nanostructures allow for an enhancement of the net density of photogenerated hot electrons.

Summary: In this study, the first synthesis of aqueous-phase CdTe magic-size clusters (MSCs) was reported, which were found to evolve from nonabsorbing precursor compounds (PCs). CdCl2 and Na2TeO3 were used as the Cd and Te sources, while l-cysteine acted as a ligand and NaBH4 as a reductant. By adding butylamine to a reaction mixture at 5°C, CdTe MSCs were obtained. The self-assembly of Cd and Te precursors, followed by the formation of Cd-Te covalent bond inside each assembly, resulted in one CdTe PC, which quasi-isomerized to one CdTe MSC in the presence of butylamine. Fragmentation of PCs at higher temperatures such as 25°C assisted the nucleation and growth of CdTe quantum dots. A novel approach was introduced to synthesize aqueous-phase CdTe PCs, which subsequently transformed into CdTe MSCs in the presence of primary amines.
