Summary: The study investigates the manipulation of stoichiometry in single-crystal VO2 beams using liquid-assisted growth. The presence of liquid V2O5 precursor submerges VO2 crystals and stabilizes their stoichiometric phase, while the uncovered crystals are oxidized by the growth atmosphere. By controlling the exposure time of VO2 to the atmosphere, different phases of VO2 can be selectively stabilized, allowing for the spatial management of multiphase structures in single VO2 beams.

Summary: Proton-coupled electron transfer (PCET) is a fundamental process in chemistry and has applications in various areas. In this Account, ongoing efforts in the Matson Laboratory to understand PCET processes at the surface of Lindqvist-type polyoxovanadate clusters are discussed. The project aims to provide atomistic resolution of H atom uptake and transfer at transition-metal oxide surfaces. The studies evaluate the reactivity of molecular metal oxides and provide design principles for materials applications.

Summary: Ca2+ acts as a structure-directing agent to transform melon-based carbon nitride to crystalline CaPHI with ordered pore channels, extended visible light absorption, and altered band structure as compared to KPHI. Protons can replace Ca2+ atoms in CaPHI to enhance porosity without disrupting crystal structure. The proton-exchanged PHI frameworks exhibit high adsorption affinity for CO2 and exceptional performance for selective carbon capture.

Summary: In this paper, a catalyst based on mixed-valence polyoxovanadate metal-organic framework (V-Cd-MOF) was reported, which can selectively oxidize aromatic alcohols to aldehydes with high yield and selectivity under additive-free conditions. The dual active sites in the polyoxovanadate cluster are responsible for the excellent catalytic performance observed.

Summary: In this study, a MOF-based adsorbent, Ni-MOF-BD, was synthesized with ethanephilic environment by incorporating dense alkyl groups into its pores. Experimental results showed that Ni-MOF-BD exhibited a high C2H6 adsorption capacity of 88.9 cm(3).g(-1) and a C2H6/C2H4 adsorption capacity ratio of 137%. Molecular simulation study suggested that the alkyl groups inside the pores contributed to the enhanced C2H6 selectivity through strong van der Waals interactions.

Summary: Spin crossover behavior in thin films of nanocrystalline particles formed by laser-mediated evaporation of cryogenically frozen suspension has been significantly altered, with a decrease in cooperativity attributed to laser-induced desorption effects. The observed changes have implications for future studies on cooperative spin transitions in laser-engineered nanocrystalline films.

Summary: Transition metal-driven small molecule activation is essential for the production of fuels and chemicals or energy supply. The use of multimetallic catalysts, where two or more metal centers act in synergy to activate and transform the substrate(s), is widespread both in nature (metalloenzymes) and (bio)inorganic chemistry. Benefits of this strategy in terms of catalytic performances result from cooperation between different metals to bind and activate a single substrate, to activate different substrates reacting together, or with one assisting metal tuning the reactivity of the active metal center.

Summary: By immobilizing dirhodium paddlewheels within metal-organic polyhedra (MOP) and assembling them into supramolecular structures, the catalytic properties of the catalysts are enhanced, particularly for the selective photochemical reduction of carbon dioxide to formic acid. The supramolecular structures exhibit higher catalytic activity per Rh atom compared to the molecular sub-unit Rh-MOP or Rh-metal-organic framework (Rh-MOF), with high turnover frequencies and production rates.

Summary: In this study, a series of bipyridine-based CTFs were synthesized with a well-controlled sequence of specific building blocks, allowing for the tailoring of physicochemical features. A direct correlation between the bipyridine content and material properties was demonstrated, and an optimal balance was found for photocatalytic hydrogen evolution reaction. Under visible light irradiation and in the presence of a platinum cocatalyst, the material exhibited high HER production rates.

Summary: Immobilizing well-defined homogenous (electro)catalysts onto conductive supports is an attractive strategy for designing advanced functional materials for energy conversion. This study introduces a pyrene anchoring group on a PNP-pincer Ir-I complex and compares its CO2 reduction activity with two pyrene-free reference complexes in DMF/water mixtures. Surprisingly, all three catalysts produce HCOO- instead of CO as the main product in homogeneous conditions. After immobilization on carbon nanotubes (CNTs), the complex is still capable of driving CO2 reduction and producing HCOO- with lower overpotential in aqueous media.

Summary: Drug delivery systems (DDSs) derived from biocompatible carriers are attractive for sustained drug release. In this work, we used porous metal-organic frameworks (MOFs) MIL-100(Fe) and MIL-53(Fe) as carriers/DDSs for two poorly soluble drugs HCT and DAP. The drug-loaded MOFs showed high loading capacity and sustained release up to 72 h under simulated physiological conditions, with no significant cytotoxicity observed.
