Summary: Magnesium-ion batteries (MIBs) are potential next-generation energy storage systems with high security and theoretical energy density. However, the lack of cathode materials with high specific capacity and cyclic stability hampers the development of MIBs. This study proposes a template-based strategy to fabricate metal-organic framework-derived CuS quantum dots encapsulated in porous carbon nanorods, which exhibit remarkable performance in magnesium storage.

Summary: A reliable synthetic approach was reported for the in-situ growth of Co-based ZIF-67 on electrospun nanofibers, followed by carbonization and sulfurization to form Co1-xS hollow polyhedrons anchored on multichannel carbon nanofibers (Co1-xS/MCF) for LIBs and SIBs. The resulting binder-free Co1-xS/MCF anode demonstrated advanced electrochemical properties for both LIBs and SIBs, attributed to the unique multichannel nanostructure and Co1-xS hollow polyhedrons providing active sites and reducing structural strain.

Summary: The development of photo-enhanced lithium-ion batteries, where exposing the electrodes to light results in higher capacities, higher rate performance or self-charging, has recently gained substantial traction. The challenge in these devices lies in the realisation of photo-electrodes with good optical and electrochemical properties. Herein, we propose copper-hexahydroxybenzene as the active photo-electrode material which both harvests light and stores energy. This material was mixed with reduced graphene oxide as a conductive additive and charge transfer medium to create photo-active electrodes. Under illumination, these electrodes show improved charge storage kinetics resulting in the photo-accelerated charging and discharging performance (i.e. specific capacities improvement from 107 mA h g(-1) to 126 mA h g(-1) at 200 mA g(-1) and 79 mA h g(-1) to 97 mA h g(-1) at 2000 mA g(-1) under 1 sun illumination as compared to dark).

Summary: Leveraging size effects, a prototypal porphyrinic MOF material Fe-MOF-525 was successfully synthesized using an ambient and fast secondary building unit (SBU)-assisted synthesis (SAS) route. Fe-MOF-525(SAS)/ITO, an electrochemical biosensor, was constructed by integrating Fe-MOF-525(SAS) as a thin film on a conductive indium tin oxide (ITO) surface. Synergistic confluence of modular MOF composition, analyte-specific redox metalloporphyrin sites, and crystal downsizing enabled benchmark voltammetric uric acid (UA) sensing with wide linear range, high sensitivity, and low detection limit.

Summary: Metal-organic frameworks (MOFs) have been used for catalyzing the oxygen evolution reaction (OER), but the critical factors determining OER performance are still not well understood. In this study, an isoreticular series of Ni-carboxylate-type MOFs was chosen to investigate the effects of carboxylate linker length and linker-linker pi-pi interactions on MOF degradation and reconstruction. The results showed that the linker controlled the transformation of MOF into different nickel hydroxide phases, which correlated the composition of Ni-MOF with the OER activity of the derived metastable nickel hydroxide phases.

Summary: The morphological changes and composition of the solid-electrolyte interphase layer of Si nanowires cycled in ethylene-carbonate (EC)/diethyl-carbonate (DEC) with different additives were investigated using experimental microscopic and spectroscopic techniques. Scanning electron microscopy and optical spectroscopy revealed that the presence of fluoroethylene carbonate (FEC) and vinylene carbonate (VC) additives preserved the nanowire morphology better compared to the additive-free electrolyte. Furthermore, the FEC additive mitigated amorphization of silicon and limited degradation of the LiPF6 salt.

Summary: Fabricating smart humidity-responsive actuators that can convert the potential of humidity into other forms of energy is crucial in the intelligence age and energy crisis. In this study, a flexible porous organic cage that can undergo reversible structural transformation upon humidity stimulation is successfully fabricated by using a polymer (PIM-1) as a matrix. The inherent porosity of PIM-1 significantly enhances the performance of the resulting actuator. These actuators can perform bionic motions and output stable voltage-level power when coupled with a piezoelectric film.

Summary: Gas or vapor-induced phase transformations in flexible coordination networks (CNs) have the potential to outperform their rigid counterparts for separation and storage applications. Ligand modification has been used to alter the properties of these materials, but they have received less attention compared to rigid CNs. In this study, a family of Zn2+ CNs with variable flexibility was investigated, and it was found that the substituent moieties attached to a linker influenced both the structure and gas sorption properties of the networks. Some networks exhibited reversible transformation from small pore to large pore phases. The insights from this study can be applied to other classes of CNs.

Summary: Compared to rigid physisorbents, switching coordination networks offer promise for gas/vapour storage and separation due to their improved working capacity and thermal management properties. X-dmp-1-Co, a coordination network exhibiting switching enabled by transient porosity, is the parent member of a family of transiently porous coordination networks [X-dmp-1-M] (M = Co, Zn, and Cd). Each member exhibits different threshold pressures for CO2, H2O, and CH4, with tuning attributed to differences and changes in metal coordination spheres and ligand rotation.

Summary: In this study, a new N-donor carboxylate linker, β-(3,4-pyridinedicarboximido)propionate (PyImPr), was used to synthesize Cd(PyImPr)(2)via two different methods, resulting in 2D or 3D supramolecular isomers. Crystal structure analysis revealed that both isomers consist of the same carboxylate bridged rod building block (RBB), and the ethylene moiety of PyImPr enabled structural flexibility. Furthermore, analysis of the Cambridge Structural Database (CSD) provided insights into the relative frequency of RBB topologies in related ML2 coordination networks.

Summary: Accurate monitoring of battery cell state of charge (SoC) and state of health (SoH) is demonstrated using a surface-mounted sensor that detects small changes in cell volume through monitoring the changes in electrical resistance of a graphene film. Rapid SoC determination without interruption to cell operation is enabled by extracting the relationship between sensor resistance and cell SoC/voltage. The sensor also detects early indications of irreversible cell expansion due to common cell failure modes, allowing mitigating steps to be taken.
