Summary: Optical image encryption technology provides valuable applications in information storage and protection by controlling emission using specific wavelengths. In this study, sandwiched heterostructural nanosheets consisting of perovskite frameworks and polycyclic aromatic hydrocarbons were investigated. These nanosheets exhibited blue emissions under UVA-I irradiation, but showed different photoluminescent properties under UVA-II. The emission in Tp-PSK was attributed to fluorescence resonance energy transfer, while photoquenching was observed in Py-PSK due to competitive absorption. The unique photophysical features of these nanosheets in a narrow UV window were exploited for optical image encrypting.

Summary: Cationic-type dimetal diselenium perchlorate molecular metal chalcogenide complexes (M2Se2(ClO4)(2), M = Mn, Zn, and Sn) were developed and applied to stabilize colloidal quantum dots (QDs). The resulting M2Se2-PbS QDs were used to fabricate near-infrared photodetectors with low dark current densities, high responsivity, and excellent specific detectivity. In addition, hybrid-type QD films using cationic and anionic MCC-PbS QDs achieved a high external quantum efficiency.

Summary: High-quality colloidal nanocrystals can be synthesized in hydrocarbon solvents with alkanoates as the common organic ligand. Water molecules with a similar number of surface alkanoate ligands are found at the inorganic-organic interface for all types of colloidal nanocrystals studied. Carboxylate ligands are coordinated to the surface metal ions, and the first monolayer of water molecules bonds to the carboxylate groups of alkanoate ligands through hydrogen bonds. Additional monolayer(s) of water molecules can be adsorbed through hydrogen bonds to the first monolayer of water molecules. The water-enriched structure of the inorganic-organic interface of high-quality colloidal nanocrystals plays a crucial role in their synthesis, processing, and properties.

Summary: This study investigates the role of ZnCl2 as an additive in the synthesis of InAs nanocrystals (NCs) using tris(dimethylamino)arsine. It is found that ZnCl2 not only improves the size distribution of InAs NCs, but also acts as a ligand to passivate their surface. The addition of a Zn precursor enables the subsequent growth of a ZnSe shell, resulting in InAs@ZnSe core@shell NCs with high quantum yield.

Summary: By introducing sodium dodecyl sulfate (SDS), PQDs with excellent properties were synthesized, effectively suppressing the efficiency roll-off of QLEDs. The SDS-based PQDs films showed enhanced radiative recombination, reduced trap density, and increased carrier mobility, leading to balanced charge carriers at high current density and significantly suppressed efficiency roll-off. QLEDs fabricated with SDS-capped PQDs exhibited improved maximum brightness and external quantum efficiency, with EQE roll-off optimized in the thickness of emitting layer, achieving a prominent achievement in this strategy.

Summary: Transition metal oxides have shown promise as cathode materials for high-capacity and high-voltage divalent batteries. However, the slow kinetics of divalent cation intercalation into the oxide host remains a major challenge. In this study, spinel-type MgxMn3-xO4 nanocrystals with different Mg/Mn ratios were selectively synthesized and their ability to shuttle Mg2+ ions was investigated. The results suggest that both the size of the nanocrystals and the Mg/Mn ratios play a role in the observed behavior.

Summary: In this study, the capacity decay mechanism of Zn-MnO2 batteries with manganese acetate as an electrolyte additive was demonstrated. It was found that zinc hydroxide sulfate has a beneficial effect on the battery capacity, but the product ZnMn3O7·2H₂O converted from basic zinc sulfate is an irreversibility inert material leading to rapid capacity fading. Notably, with an increased low cutoff voltage, the battery showed a high capacity and excellent stability. This research provides a new perspective for the development of Zn-MnO2 batteries.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
