Summary: High-resolution perovskite quantum dots (PeQDs) arrays printed by electrohydrodynamic (EHD) inkjet printing show great application prospects in fields of micro-display. A morphology uniformization strategy using a nonpolar binary solvent system of 1,3,5-triethylbenzene and n-tetradecane is proposed to prepare the didodecyldimethylammonium bromide (DDAB)/PbBr2 passivated PeQDs inks. The high-resolution logo and miniature quick response code printed by EHD inkjet reach far higher resolution than micro-LED.

Summary: This study demonstrates high-efficiency emission depletion through surface migration using the effects of surface quenching and energy migration in nanocrystals. The researchers achieved super-resolution microscopy with low saturation intensities and sub-20 nm lateral resolution by utilizing this mechanism. The approach overcomes the limitations of high-intensity STED microscopy and offers autofluorescence-free, re-excitation-background-free imaging at significantly lower saturation intensities than conventional fluorophores.

Summary: Atomic force microscopy (AFM) is a nano-mechanical tool used for biological studies at the molecular scale, measuring surface topography, mechanical, and electrical properties. Integrating AFM with super-resolved fluorescence microscopy addresses the resolution mismatch issue, while also utilizing the label-free imaging capabilities of AFM to complement fluorescence images. Recent research highlights the importance of combining these techniques in biological research for better specificity and resolution.

Summary: This study explores water-dispersed perovskite CsPbBr3 nanocrystals as a fluorophore for single-molecule localization microscopy (SMLM). The CsPbBr3 NCs fabricated by a one-step mechanochemical method exhibit ultrahigh photoluminescence quantum yield (PLQY), frequent fluorescence blinking, proper duty cycle, and long-term photostability, achieving an extremely high location precision of around 3 nm. The spatial resolution of SMLM images depends on the size of CsPbBr3 NCs, with a size of approximately 23 nm providing clear distinction of closely spaced NCs. Furthermore, the CsPbBr3 NCs can retain their excellent fluorescence characteristics even after surface biofunctionalization, expanding the possibilities for perovskite quantum dot-based SMLM in bioimaging.

Summary: Metallic and semimetallic mesoporous frameworks have unique properties and wide applications. However, semimetallic mesoporous structures are difficult to obtain using traditional methods. In this study, monodisperse mesoporous antimony nanospheres were successfully synthesized using a selective etching route, with tunable pore sizes. The antimony nanospheres showed wide absorption in the visible to second near-infrared (NIR-II) region, with promising NIR-II photothermal performance and photoacoustic signal. These multifunctional nanospheres could be used for synergistic photothermal/chemo therapy guided by NIR-II photoacoustic imaging.

Summary: Organic electrochemical transistors (OECTs) are widely used in low power circuits, biosensors, and neuromorphic computing. However, the choice of high-performance n-type polymers for OECTs is limited. This study reports on three non-fused, planar polymer materials with increasing polar side chains, which improve the OECT performance. The research demonstrates that the performance of OECTs increases with the number of polar side chains, resulting in higher hydrophilicity and electron affinities.

Summary: The study shows that the p(T) spectra of strange (anti)hadrons produced in central Au+Au collisions can be explained by the equal velocity combination of quarks and antiquarks during hadronization. The yield ratios of different hadrons simply correlate with each other and their experimental data, except for one case at low collision energies.
