Summary: The study found significant seasonal differences in sub-3 nm particle concentrations in the atmosphere in Hyytiala, Finland, as well as notable diurnal and seasonal differences in aerosol precursor vapor concentrations. This suggests that both highly oxygenated organic molecules (HOMs) and sulfuric acid play a significant role in new particle formation in the boreal forest, with potential seasonal differences in the formation pathways that need further investigation.

Summary: This study successfully achieved the hydrothermal synthesis of small and rounded fluorescent nanodiamonds, which is of significant interest for various applications, particularly in biology. The creation of color centers, specifically nitrogen-vacancy and silicon-vacancy color centers, in the grown nanodiamonds validated the cubic diamond structure. This novel growth technique holds great promise for demanding applications in biology due to its simplicity and ability to grow high-quality diamonds.

Summary: This study demonstrates that light metals can generate optical responses comparable to noble metal nanoclusters, but at shorter wavelengths. The synthesis of size-uniform sub-3 nm aluminum nanocrystals with photoluminescence in the ultraviolet range, and the partial modulation of the photoluminescence, suggest new frontiers for nanocluster research with light metals.

Summary: The study demonstrates the impact of sub-3nm particle formation and growth on particle number in the atmosphere over Hyderabad, India. New particle formation events often lead to growth of particles to larger than 10 nm, but not all events exhibit this feature. Various meteorological factors and air mass direction differ between NPF&G and NPF events, potentially influencing the condensational growth of organic vapors.

Summary: This study reports the successful synthesis of uniformly sized and ultrafine Cu2O platelets, which exhibit excellent performance and stability for the visible light driven photocatalytic reduction of N-2 to NH3. The high activity is attributed to long-lived photoexcited electrons in trap states, an abundance of exposed active sites, and the underlying support structure.

Summary: In this study, a new catalyst for ambient CO2 electroreduction (CER) was developed by attaching sub-3 nm Cu particles onto perovskite oxides. The strong metal-support interactions (SMSIs) between Cu and perovskite enabled efficient and stable conversion of CO2 to C2+. This catalyst showed comparable or better performance than most reported Cu-based heteronanostructures, with significant improvements in activity, selectivity, and stability.

Summary: This study demonstrates quantitative control over asymmetric polymer grafting on triangular Au nanoprisms based on polymer scaling theory. The authors show that polymers can selectively adsorb onto nanoparticle surfaces already partially coated by other chains, resulting in the formation of patchy nanoparticles with broken symmetry. These asymmetric nanoparticles exhibit intriguing plasmonic properties and their formation can be accurately predicted by a developed theory.
