TL;DR: This review intends to provide an update on recent progress in various applications of different MOF-based sensors on the basis of their luminescent and electrochemical responses towards small molecules, gas molecules, ions, ions), pH, humidity, temperature, and biomolecules.
Abstract: Metal-organic frameworks (MOFs) as chemical sensors have developed rapidly in recent years. There have been many papers concerning this field and interest is still growing. The reason is that the specific merits of MOFs can be utilized to enhance sensitivity and selectivity by various energy/charge transfers occurring among different ligands, ligand, and metal centers, such as from ligands to metal centers or metal centers to ligands, as well as from MOF skeletons to guest species. This review intends to provide an update on recent progress in various applications of different MOF-based sensors on the basis of their luminescent and electrochemical responses towards small molecules, gas molecules, ions (cations and anions), pH, humidity, temperature, and biomolecules. MOF-based sensors function by utilizing different mechanisms, including luminescent responses of "turn-on" and "turn-off", as well as electrochemical responses.

TL;DR: The as-prepared NiCo2 S4 nanotubes/Ni foam electrode shows a high specific capacitance, excellent rate capability, and good cycling stability, which suggests its promising application for electrochemical capacitors.
Abstract: Arrays of NiCo2 S4 nanotubes on nickel foam were prepared by means of a two-step method, and were directly applied as a binder-free supercapacitor electrode. Such a binder-free method enables intimate contact between the current collector and the active materials, and can effectively improve ion and charge transportation. As a result, the electrochemical performances of supercapacitors can be improved. The as-prepared NiCo2 S4 nanotubes/Ni foam electrode shows a high specific capacitance (738 F g-1 at 4 A g-1 ), excellent rate capability (78 % capacitance retention at 32 A g-1 ), and good cycling stability (retention capacity of 93.4 % after 4000 cycles), which suggests its promising application for electrochemical capacitors.

TL;DR: In this paper, the authors describe the various strategies that have been effectively utilised to achieve switchable and tunable fluorescence in the organic solid state, including chemical modification, molecular packing and conjugation of fluorophores.
Abstract: Organic fluorescent materials have been an integral part of recently emerged optoelectronic device technologies owing to their good photophysical properties such as high quantum yields and significant photostability. In particular, switchable and tunable solid-state fluorescence has attracted increasing attention in recent years both in the field of fundamental research and industrial applications. Unlike in solution, fluorescence in the solid state is a collective phenomenon of molecules that are commonly modulated through controlling molecular packing and the electronic conjugation of fluorophores. Several strategies, including chemical modification, have been developed to alter the fluorophore molecular arrangement in the solid state. This Review article describes the various strategies that have been effectively utilised to achieve switchable and tunable fluorescence in the organic solid state.

TL;DR: An insight is given into the characterisation of metal-mediated base pairs and into the structures of the resulting metal-modified nucleic acids.
Abstract: Metal-mediated base pairs represent an elegant way for the site-specific functionalisation of nucleic acids. In this type of base pair, the hydrogen bonds between complementary nucleobases are replaced formally by coordinative bonds to one or more transition-metal ions. This Review presents an overview of metal-mediated base pairs reported so far. It gives an insight into the characterisation of metal-mediated base pairs and into the structures of the resulting metal-modified nucleic acids. In addition, a summary of applications exploiting the formation of metal-mediated base pairs is presented. The applications include, for example, metal-ion sensors of various types, a protein sensor, and DNA-based molecular machines. Initial reports on the potential use of metal-mediated base pairs in the context of charge transfer through nucleic acid double helices are summarised as well.

TL;DR: In this paper, the thermodynamics and kinetics aspects of the iron-air battery, the operational variables and cell components are considered, and current challenges and assessing recent developments are highlighted.
Abstract: Recent interest in the iron–air flow battery, known since the 1970s, has been driven by incentives to develop low-cost, environmentally friendly and robust rechargeable batteries. With a predicted open-circuit potential of 1.28 V, specific charge capacity of <300 A h kg−1 and reported efficiencies of 96, 40 and 35 % for charge, voltage and energy, respectively, the iron–air system could be well suited for a range of applications, including automotive. A number of challenges still need to be resolved, including: efficient and moderate-cost bifunctional oxygen electrodes, low-cost iron electrodes able to decrease corrosion and hydrogen evolution, new cell designs using additive manufacturing technologies and mathematical models to improve battery performance. This Minireview considers the thermodynamics and kinetics aspects of the iron–air battery, the operational variables and cell components, thereby highlighting current challenges and assessing recent developments.
