Summary: A growth model based on monomer diffusion dynamics was proposed to synthesize colloidal InAs QDs with a size over 9.0 nm and a narrow size distribution. By controlling the diffusion dynamics, the authors were able to overcome the size limitation of nanocrystal growth in solution and extend the spectral coverage of InAs QDs beyond 1S(max) of 1600 nm.

Summary: This study reports a method for synthesizing high-quality and size-tunable InSb CQDs using commercially available precursors and under standard colloidal synthesis conditions. By changing the surface ligands of the CQDs, an increase in excited-state lifetime, efficient carrier multiplication, and slower carrier annihilation are observed. This work overcomes a major challenge in synthesizing high-quality InSb CQDs and opens up new possibilities for Pb- and Hg-free CQDs in SWIR applications.

Summary: In this study, a facile and rapid surface-plasma-induced method was used to synthesize a 2D/0D/2D hybrid nanostructure of N,S co-doped carbon dots intercalated few-layer MoS2/graphene nanosheets as a catalyst for the hydrogen evolution reaction (HER). The ternary composite of NSCD@MoS2/G showed superior catalytic activity, low onset potential, and high stability, with evidence of large catalytic edge sites and electrical coupling. This approach opens up new possibilities for the synthesis of efficient heterostructures with potential energy-related applications.

Summary: Fluorescent silicon quantum dots (SiQDs) with excellent properties have attracted attention for nitrite detection. The green-emitting SiQDs exhibit selectivity, good water dispersibility, and stability for potential routine analysis in food samples. The sensor displays a significant linear relation between fluorescence quenching efficiency and the concentration of NO2-.

Summary: Green fluorescent carbon quantum dots were successfully synthesized using a hydrothermal method, and the addition of SnCl5·5H2O catalyst significantly reduced the pyrolysis reaction time and resulted in a higher quantum yield. Additionally, these green fluorescent carbon quantum dots exhibited selective quenching by NO2- ions and showed a good linear relationship within a certain concentration range.

Summary: This study investigated the formation of nutrient Chia plant as a carbon source for the production of CQDs through a hydrothermal strategy, as well as analyzing their biological distribution and cytotoxicity. The obtained CQDs showed satisfactory fluorescence and quantum yield under optimal conditions, while confirming their non-toxicity and colloidal stability in various physiological conditions. Additionally, the biological distribution of CQDs was tested through in vivo experiments in rats, demonstrating their cost-effectiveness, biocompatibility, and bioavailability for potential medical imaging applications.
