Summary: This study designs a room-temperature reaction to trap reaction intermediates in the prenucleation stage of ZnSe QDs and provides evidence that both nonclassical and classical pathways are necessary for explaining the nucleation and growth of aqueous-phase QDs.

Summary: This study provides a detailed description of the transformation pathway of CdSe nanospecies from one absorption doublet to another, as well as the role of precursor compounds in enabling this transformation. The research also sheds light on the structural nature and evolutionary behavior of these nanospecies with sharp doublets in optical absorption.

Summary: Electrical resistivity measurements and X-ray diffraction studies of a dual-layered organic conductor (ET)(4)ZnBr4(1,2-C6H4Cl2) demonstrate abrupt changes at 320K, with polymorphic transformation at T-p around 320K. Anharmonic effects are observed in the crystal structure in the 260-315K range, and splitting of ethylene groups of ET is observed near the phase transition at 315K, indicating disordering of ET in the low-temperature phase. The final rearrangement of the crystal structure from triclinic to tetragonal occurs above 315K.

Summary: Lamellar silver thiolates exhibit reversible temperature-dependent optical transitions from blue to near-infrared, with the structural flexibility of Ag-MPA being responsible for these transitions. The polymer-like nature of Ag-MPA allows for scalability of the reaction and easy processing for a wide range of applications.

Summary: Converting and patterning high-quality perovskite quantum dots (PQDs) into flexible thin films is important for solid-state optical applications. However, their poor stability and low quantum efficiency after film formation hinder their usability. This study demonstrates an in situ synthesis strategy to prepare long-term stable CsPb(Br0.3I0.7)(3)@poly(methylmethacrylate) (PMMA) PQDs fibers with thermal responsive fluorescence performance, which can rapidly and reversibly quench and recover between heating and cooling cycles. This temperature-reversible luminescence characteristic not only deepens the understanding of perovskite material's temperature-dependent phase transition behavior but also broadens their applications in various temperature-responsive fields.

Summary: A hybrid blue phase liquid crystal material with a wide blue phase temperature range of over 40K was prepared and its optical, electro-optical, and dielectric properties were investigated. The hybrid material, which contained cadmium telluride quantum dots in polymer stabilized blue phase liquid crystals, showed significantly improved thermal stability compared to other blue phase liquid crystal systems. In addition, the present work also observed a substantial reduction in operating voltage, improvement in transmittance, and increased Kerr constant with a threefold increase in dielectric permittivity in quantum dots doped polymer stabilized blue phase liquid crystals. The examined hybrid materials with wide blue phase temperature range and superior electro-optical properties are expected to be important for various photonic applications.

Summary: This article discusses the research on promoting the selective production of colloidal semiconductor metal chalcogenide (ME), magic-size clusters (MSCs), or quantum dots (QDs). The study reveals that the size of precursors determines the evolution pathways of MSCs and QDs. The addition of carboxylic acid can regulate the self-assembly behavior of the precursors, leading to directed evolution of either MSCs or QDs.

Summary: Inorganic-organic (IO) hybrid semiconductors are fascinating optoelectronic materials due to their unique crystal structure, wide range of crystal phases, tunable bandgap, optical exciton characteristics, and optoelectronic properties. This study investigates the digitized intercalation process and dynamic structural deviations/evolution in mixed IO hybrid systems, resulting in the formation of 2D or 3D hybrid networks. Real-time photoluminescence monitoring reveals the progressive shift of exciton energies, providing insight into the nature of multiphase crystal packings in IO hybrid semiconductors.

Summary: By blending two different types of quantum dots to control electrical properties, films containing Ag2Se intraband quantum dots were prepared and p-n heterojunction diodes with strong rectifying characteristics were successfully fabricated. The peak specific detectivity at 4.5 mu m measured an orders of magnitude improvement compared to the previous generation of intraband quantum dot detectors at room temperature.

Summary: In this study, we combine the concepts of a Weyl scaling invariant dark energy action and the gravastar theory. By utilizing the Tolman-Oppenheimer-Volkoff equation, we investigate the structure and dynamics of gravastars. Our Mathematica notebooks demonstrate that the structural changes of gravastars are determined by the action and equation of state, and the radii at which these changes occur are not predetermined. Additionally, we calculate the effects of a very small black hole wind using a relativistic extension of standard pressure-driven isothermal stellar wind theory.

Summary: A systematic study was conducted on the Ag+-ion conducting behavior in AgI-loaded mesoporous aluminas (MPAs) in the sub-10 nm region. The highest conductivity was found when AgI was loaded into MPA with pore diameter of 7.1 nm (7.2 x 10-4 S cm-1 at 25 °C).

Summary: Recent advances in circuit quantum electrodynamics have enabled the observation of inelastic collisions between single microwave photons and instantons, offering insights for research in other quantum field theoretical contexts. The study also indicates that the inelastic scattering probability can significantly exceed the impact of conventional Josephson quartic anharmonicity and mach order-unity values.
