Summary: This study presents a facile and environmentally friendly method for synthesizing C, N co-doped mesoporous TiO2 nanocrystals, using IL-assisted microwave synthesis, resulting in small-sized TiO2 with well-developed mesoporous structure and abundant C, N dopants. The material exhibits high specific-surface area, excellent hydrophilicity, elevated valence-band edges, abundant defect levels, and narrowed band-gap, leading to improved visible-light absorption, reduced photogenerated electron-hole recombination, and rapid charge transfer and surface-catalyzed reactions.

Summary: In this study, N-doped carbon-coated Fe1-xS (Fe1-xS@NC) sheets were synthesized and anchored on rGO to form Fe1-xS@NC-rGO composites. The coating of N-doped carbon on Fe1-xS surfaces improved the surface conductivity and electrochemical kinetics of Fe1-xS, facilitating the conversion between lithium polysulfides and Fe1-xS. Additionally, the N-doped carbon coating acted as a barrier to prevent the dissolution of polysulfides and loss of active ingredients. The double protection of the N-doped carbon layer and flexible rGO substrate minimized the structural damage caused by cyclic expansion and contraction. Fe1-xS@NC-rGO exhibited excellent rate performance, reversible capacity of 939.5 mA h g(-1) after 1690 cycles at a current density of 1.0 A g(-1), and outstanding charge-discharge performance and long-term cycling stability. This work demonstrates the synergistic enhancement of Fe1-xS performance and highlights the effectiveness of the synthetic strategy for carbon-based material-protected sulfides in developing superior LIB electrodes.

Summary: In this study, ionic liquid-modified multi-walled carbon nanotubes (MWCNT-IL) were used as a conductive network to form a Na3V2(PO4)2O2F-based cathode (NVOPF@MWCNT-IL). The use of MWCNT-IL allowed for the dispersion of Na3V2(PO4)2O2F crystals and the formation of uniform Na3V2(PO4)2O2F cubes. The NVOPF@MWCNT-IL cathode exhibited improved cycling stability and superior rate performance.

Summary: In this study, mussel-inspired chemistry was combined with two-dimensional HOIPs, resulting in the synthesis of a new crystal (HDA)2PbBr4. The organic cation dopamine was introduced into PDA to form (HPDA)2PbBr4. The dissolved inorganic components of layered perovskite in DMF solution, combined with H2O2, greatly facilitated the polymerization of dopamine. The resulting material, PDA-1, exhibited excellent semiconductor properties and robust adhesion, allowing for the formation of self-adhesive photoelectric coatings on various interfaces.

Summary: In this study, two Bi-IOHMs materials with different ionic liquid cations and the same anionic units were successfully synthesized and characterized. The compounds exhibit zero-dimensional ionic structures and phosphorescence at room temperature upon UV light excitation. Compound 2, with a more rigid supramolecular structure due to the variation in ionic liquids, shows a significant enhancement in photoluminescence quantum yield compared to compound 1. This work provides new insights into the luminescence enhancement and temperature sensing applications of Bi-IOHMs.

Summary: Zero-dimensional (0D) metal halides based on environmental friendliness, low cost, and earth-abundant elements have gained attention for various applications. In this study, Mn-doped 0D C4H12N2ZnX4 (X = Cl and Br) with strong green emission was developed for scintillator and white light-emitting diode (WLED) applications. Mn doping effect on the electronic structure of C4H12N2ZnX4 was investigated using spectroscopic studies and density functional theory (DFT) calculations. The results showed that Mn doping reduced the bandgap and enhanced the Mn d-d emission, resulting in high photoluminescence quantum yield (PLQY) and luminous efficacy in Mn-doped C4H12N2ZnX4-based WLEDs.

Summary: Two isostructural supertetrahedral T3 cluster-based chalcogenide compounds were synthesized using an ionic liquid-assisted precursor technique. It was found that the highly-dispersed In-Se cluster exhibited approximately 5 times higher photocatalytic H-2 evolution activity than that of the solid-state under visible light irradiation. On the other hand, the photocatalytic performance of the highly-dispersed In-S cluster was only slightly higher than that of the solid state due to its inferior visible-light absorption capability.

Summary: In this study, a new class of second-order nonlinear optical (NLO) crystals, non-pi-conjugated piperazine (H10C4N2, PIP) metal halides, represented by two centimeter-sized, noncentrosymmetric organic-inorganic metal halides (OIMHs) have been identified. H12C4N2CdI4, the first OIMH prepared, exhibits poor NLO performance due to its structure containing a CdI4 tetrahedron. However, by replacing CdI4 with a highly polarizable CdNI3 tetrahedron to obtain H11C4N2CdI3, a significant enhancement in NLO performance is achieved.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: In this study, the pore size of calcium-based metal organic frameworks (Ca-MOFs) was tunable and the fluorescence sensing towards a specific chemical substance was achieved by adjusting the pore size. The results showed that the pore size of Ca-MOFs could be finely regulated by altering the chemical structure of the coordinated amides, allowing for selective adsorption of different molecules.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
