Summary: It is crucial to enhance the thermoelectric properties of n-type thermoelectric materials, Ag2Se, through nanoscale hybridization and this method is more effective than conventional alloying or ion-doping methods. A series of n-type Ag-0: Ag2Se materials were successfully prepared through a surfactant-free, aqueous solution-based method under ambient conditions, allowing for control over phases and compositions using silver nanoparticles. By optimizing the synthetic process, an optimal excess of Ag-0 was determined and the thermoelectric properties were improved. The achieved ZT values in this study are higher than those reported for beta-Ag2Se synthesized via wet chemistry methods at room temperature.

Summary: This study offers insights into the utilization and quantification of thermoplasmonic properties in gold nanorod arrays and demonstrates their practicality in various photothermal processes. The thermochromic studies show that the surface temperature of the arrays can reach approximately 250 degrees C within 15 minutes of irradiation, which is independently validated with infrared thermometric imaging studies. The research also reveals that the maximum impact of surface temperature is observed when substrates are adsorbed onto the arrays.

Summary: The aim of this paper is to examine the influence of global mood on cryptocurrencies trading activity. By constructing a real-time language-free proxy of sentiment based on songs chosen by investors, the study finds that music sentiment is a reliable indicator of individuals' mood swings. Interestingly, the research shows a negative and significant correlation between music sentiment and trading volume as well as price volatility, which is not influenced by recall bias or specific cryptocurrencies, and is robust to listeners' preferences. The effect persists for up to four lags in price volatility and reverses on day 3 for trading volume.

Summary: Researchers prepared large-yield stable CsPbBr3@Cs4PbBr6 core-shell nanocrystals by adjusting the initial ratio of Cs/Pb using one-pot route. The growth process of CsPbBr3@Cs4PbBr6 nanocrystals was analyzed, and their stability was evaluated under atmospheric conditions, showing excellent stability compared to pure phase CsPbBr3 nanocrystals. A writable fluorescent ink developed by mixing CsPbBr3@Cs4PbBr6 nanocrystals with thermoplastic polyurethane exhibited excellent heat-resistance stability under multiple heating-cooling cycles, providing alternative options for the commercial development of perovskite materials.

Summary: The discovery of the animal thermosensory channel TRPV1, which was awarded the 2021 Nobel prize, shares notable features with the higher plant thermosensory channel CNGC2/4. Both channels respond to changes in plasma membrane fluidity induced by temperature, leading to hyperphosphorylation of the HSF1 transcription factor via a specific heat-signaling cascade.

Summary: In this paper, core-shell structured CsxWO3@TiO2 was prepared by coating CsxWO3 nanoparticles with TiO2. The crystal structure and optical properties of the material were studied. The results showed that TiO2-coated CsxWO3 exhibited good stability in actual environment, and its transparent heat shielding performance decreased with the increase in TiO2 shell thickness. This work provides a new route to promote the applications of tungsten bronze as heat shielding materials.

Summary: This study investigates the size-dependent change of electronic band structure in CuFeS2 nanoparticles. Experimental results show that the optical resonance absorption peak shifts towards longer wavelengths and the optical band gap becomes smaller as the particle size decreases. Theoretical modeling supports these findings, revealing the size dependence of the band structure, particularly the change in the intermediate band (IB). The shifts in the optical resonance peak position are attributed to a tri-band quantum confinement effect, resulting in the expansion of both the valence band (VB) to IB and the IB to conduction band (CB) gaps with decreasing particle size. The transitions between the IB and CB have a minor role in the optical spectrum. The linear optical Lorentzian model predicts that the optical resonance peak can be tuned across the visible range by partially filling the IB, lowering the CB, or expanding the IB.

Summary: Trivalent lanthanides are commonly used in sodium yttrium fluoride nanocrystals to improve their optical properties. At low dopant concentrations, large lanthanides exhibit an anisotropic distribution in the hexagonal yttrium sublattice, suggesting the formation of one-dimensional dimers or chains. Our research indicates that the concentration quenching threshold of beta-NaYF4 nanocrystals is lower than that of their cubic counterparts, and the anistropic distribution can be modulated by microstrain management via alkali metal codoping. Understanding dopant distribution in inorganic crystals may lead to the development of new materials and properties in the future.

Summary: Inorganic halide perovskite quantum dots have been widely used as efficient active materials in optoelectronic applications. In this work, we coupled a layer of perovskite quantum dots to dielectric Mie resonators to simultaneously exploit the Purcell effect and increase light extraction, resulting in an 18-fold increase in luminescence. Our numerical simulations and experimental measurements revealed the interplay of these two effects and provided guiding principles for maximizing the output intensity of quantum emitters and classical emitters in perovskite-based optoelectronic devices.

Summary: To address vacancy problems in the production of high-quality nanoscale crystals, we developed a convenient strategy involving lattice reconstruction and dynamic metal complex docking to produce ultrasmall and bright core-shell upconversion nanoparticles. By utilizing lanthanide ion-oleic acid complexes during post-annealing in solution, we effectively removed vacancies in the nanocrystals and minimized surface quenching, leading to improved performance. Our strategy offers insights into lattice engineering and presents a general method for purifying functional nanocrystals for various applications, such as single-molecule tracking, quantum optics, and energy conversion.

Summary: This article introduces a method based on lithographically patterned perovskite nanocrystal arrays to measure the radiation vectors from X-rays to visible light. By modifying nanocrystal arrays with specific orientations, three-dimensional light-field detection and spatial positioning of light sources can be achieved. Three-dimensional object imaging and visible light and X-ray phase-contrast imaging are also demonstrated by combining pixelated nanocrystal arrays with a color charge-coupled device. The ability to detect light direction beyond optical wavelengths through color-contrast encoding could enable new applications.

Summary: Flexible perovskite-based X-ray detectors have great potential for imaging due to their high sensitivity, low detection limit, low-cost, and large-area fabrication. However, their inefficient X-ray-to-current conversion has been a challenge. In this study, an integrated, self-powered X-ray detector based on CsPbBr3 quantum dots and a MAPbI(3) photoelectric conversion layer embedded with perylene diimide molecules was fabricated. The detector showed improved performance with enhanced sensitivity and a stable output over bending cycles.

Summary: This study reports the direct observation of ultralong-lived upconversion luminescence by coupling molecular triplet orbitals to lanthanide-doped nanocrystals. Nanohybrids capable of producing ultralong upconversion lifetimes up to 1.37 s and tunable color output are constructed, surpassing the intrinsic lifetime of lanthanide ions by a factor of 4500. In addition, direct activation of the triplet state by exciton from the 4f levels is observed, significantly reducing the required photon energy for stimulation of the triplet state compared to the process involving intersystem crossing.
