Summary: Step-shaped adsorption-desorption of gaseous payloads by flexible metal-organic frameworks can facilitate the delivery of large usable capacities with reduced energetic penalties. The multivariate linker approach is a powerful tool for tuning the phase change behavior of flexible frameworks. In this work, a multivariate framework was developed with a considerably reduced threshold pressure and desirable adsorption-desorption profile for efficient storage and delivery of weakly physisorbing species.

Summary: The study investigates the structural environment of V-IV ions doped in the metal-organic framework DUT-5(Al) using electron paramagnetic resonance (EPR), revealing four different vanadium-related spectral components. Various experimental techniques, such as Q-band Electron Nuclear Double Resonance (ENDOR), SEM, EDX, XRD, and FTIR, are utilized to investigate the origin of these components. Simulations based on the experimental data successfully reproduce the spectra and provide insights into the contribution of different vanadyl species in relation to V-concentration.

Summary: In this study, a palladium catalyst loaded on a hydrogen storage support-Pd/LaNi5 was synthesized and its catalytic property in reversible hydrogen storage of N-ethylcarbazole (NEC) was investigated. The results showed that the catalytic performance of 1 wt%Pd/LaNi5 was significantly better than that of Pd/Al2O3 with the same Pd loading. This improvement was attributed to the ample lattice hydrogen bonding sites and fast bulk hydrogen diffusion kinetics of LaNi5.

Summary: This review article focuses on supercapacitor electrode materials based on composites of metal-organic frameworks (MOFs) and conductive polymers (CPs). The combination of MOFs and CPs is an effective strategy to enhance the electrochemical performance of electrode materials. MOFs have unique properties such as high porosity and large surface area, but their low electrical conductivity limits their energy storage applications. CPs, on the other hand, have controllable conductivity and mechanical properties, making them attractive for supercapacitor applications. The review discusses hybridization strategies and provides a summary of recent advances in MOF@CP hybrids.

Summary: Metal-organic frameworks (MOFs) provide great opportunities for gas uptake, storage, and separation due to their porosity, chemical tunability, and flexibility. The MUF-16 family, with exceptional gas adsorption properties, including selective uptake of carbon dioxide, shows flexibility upon the adsorption of hydrocarbon gases. Through in situ synchrotron X-ray and neutron diffraction, we identified the framework-gas interactions and utilized inelastic neutron scattering and calculations to understand the dynamics of the flexibility. C-3 hydrocarbons effectively bridge hydrogen-bonded carboxyl dimers in the framework, leading to pore expansion and inhibition of certain framework motions.

Summary: In this study, a reversible three-dimensional framework that binds ammonia by cooperative insertion into its metal-carboxylate bonds to form a dense, one-dimensional coordination polymer is reported. This unusual adsorption mechanism provides considerable intrinsic thermal management and, at high pressures and temperatures, cooperative ammonia uptake gives rise to large working capacities. The threshold pressure for ammonia adsorption can further be tuned by almost five orders of magnitude through simple synthetic modifications, pointing to a broader strategy for the development of energy-efficient ammonia adsorbents.

Summary: Traditional energy decomposition analysis (EDA) methods can explain the decomposition of non-covalent electronic binding energies, but they neglect entropic effects and nuclear contributions to the enthalpy. In order to reveal the chemical origins of trends in free energies of binding, we introduce the concept of a Gibbs decomposition analysis (GDA). By coupling the absolutely localized molecular orbital treatment of electrons in non-covalent interactions with the simplest possible quantum rigid rotor-harmonic oscillator treatment of nuclear motion at finite temperature, we can decompose enthalpic and entropic contributions to the free energy of association. The results show enthalpic trends that generally track the electronic binding energy and entropic trends that reveal the increasing price of loss of translational and rotational degrees freedom with temperature.

Summary: The process of separating oxygen from air to create oxygen-enriched gas streams is important in both industrial and medical fields. However, existing technologies for this process are energy-intensive and require infrastructure. This study demonstrates that a metal-organic framework, Al(HCOO)3 (ALF), can effectively adsorb oxygen at near-ice temperatures, with good time-dependent selectivity. ALF exhibits a high oxygen adsorption capacity of approximately 1.7 mmol/g at 190K and atmospheric pressure, and approximately 0.3 mmol/g at salt-ice temperatures of 250K. ALF shows potential as a low-cost option for oxygen separation applications.

Summary: The exclusive capture of carbon dioxide (CO2) from hydrocarbon mixtures is crucial in the petrochemical industry. A new study introduces a ultramicroporous material, ALF, which can selectively capture CO2 from hydrocarbon mixtures with high capacity and efficiency. The material's unique pore chemistry allows for molecular recognition of CO2 by hydrogen bonding, while rejecting other hydrocarbons.

Summary: Evidence has been found for a spin liquid state in the triangular-lattice material NaRuO2, where the cooperative interplay of spin-orbit coupling and correlation effects produce a fluctuating magnetic ground state. Low-temperature spin excitations in NaRuO2 generate a metal-like term in the specific heat and a continuum of excitations in neutron scattering, resembling spin liquid states found in triangular-lattice organic magnets. Further cooling leads to a crossover into a highly disordered spin state with persistent fluctuations.
