Summary: Inorganic perovskite nanocrystals (IPNCs) have excellent optoelectronic properties, but anion migration during LED preparation and small-scale syntheses have been a problem. To address this, CsPbBr3 was synthesized in the form of nanoplatelets using only Br as the anion to eliminate anion migration and enable large-scale synthesis. The synthesis was performed at room temperature under ambient conditions. The obtained IPNPL exhibited a high photoluminescence quantum yield (PLQY) of 78% at 460 nm, and LEDs fabricated using IPNPLs showed an electroluminescence peak at 461 nm. This synthetic method has the potential to commercialize IPNCs and contribute to the next-generation display market.

Summary: Multiscale micro-nano fibrous structures are a research area in material science that has gained attention in recent years. These structures, found in nature's materials, exhibit unique properties such as mechanical behaviors, high surface area to volume ratio, and multiscale biological functionalities. By systematically studying the mechanical effects of each constituent, we demonstrate the biomimetics of a multiscale composite material system and its influence on mechanical behavior. Fabrics made from various materials were characterized to understand the structure-function relationship in multiscale biomimetic constructs (MSBCs).

Summary: The nanoscale-cavity effect significantly increases the emission efficiency of inserted QDs and enhances the FRET efficiency, particularly for radiating dipoles in QWs oriented perpendicular to the sidewalls of the nano-holes. This effect modifies the radiation behavior of light emitters inside a nano-hole through the Purcell effect, resulting in stronger far-field emission.

Summary: The coupling of terahertz optical techniques to scattering-type scanning near-field microscopy (s-SNOM) has opened up new possibilities for studying nanoscale phenomena in wide bandgap materials. In this study, researchers successfully demonstrated s-SNOM using blue light, which allowed for the generation of terahertz pulses directly from bulk silicon with nanoscale resolution. This breakthrough enables the extraction of spectroscopic information that is not obtainable with near-infrared excitation, providing a new realm of possibilities for studying wide-bandgap materials.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor. The activation energy of methane dissociation is also affected by the Al-Al distance.
