Electrolytes play a crucial role in the performance of electrochemical energy storage systems, such as batteries and supercapacitors. Their main function is to act as a medium for ion transport between the electrodes, which is essential for the charge and discharge processes. Beyond this, the electrochemical performance of the device is strongly affected by the various properties of the electrolytes such as its ionic conductivity, chemical, thermal and electrochemical stability, chemical compatibility, etc. The intrinsic limitation of the aqueous electrolytes such as its decomposition as high voltage operations led to the development of better electrolytes for batteries and supercapacitors. This included non-aqueous electrolytes, inorganic solid-state electrolytes, and gel polymer electrolytes. This feature article summarises the various approaches to designing a highly efficient electrolyte for the targeted application along with the suitable device fabrication strategy adopted in the current literature to meet the balanced electrochemical performance with the liquid device.

An efficient method for the synthesis of [18F]-difluoromethylated alkanes has been developed by combining [18F]radiofluoride with monofluoroalkyl triflates. This method uses [18F]KF/K2.2.2. as the fluorine source. It features synthetic simplicity without tedious precursor preparation, high RCC and RCY, good functional group tolerance, and is silver salt-free, providing potential for developing new PET agents.

We report an unanticipated catalytic performance for ethanol dehydration in dealuminated Beta zeolite with framework aluminum species at levels as low as 120 ppm. The residual aluminum species playeda dominant role, as proved by IPA-TPD, an n-butanol probe reaction, and DFT calculations.

A novel Pd/NBE-catalyzed intermolecular dehydrobicyclization of heteroaryl iodides for the synthesis of polycyclic nitrogen-containing heterocycles is reported. In this work, the N-protected aryl carbamoyl chloride serves as a source of acylation. The products resulting from the direct C–H functionalization of heteroaryl iodides are smoothly obtained without catalyst poisoning by heteroatom.

We develop a Bi-assisted pyrolysis method to fabricate rich-edge N-doped carbon anchored with Fe active sites using Fe-doped Bi-MOF as a precursor. During pyrolysis, Bi aggregation forms edge-rich nanobelts, while the subsequent Bi evaporation generates mesopores, increasing edge-hosted Fe site density. The resulting catalyst exhibits superior intrinsic activity and selectivity for CO2-to-CO, outperforming in-plane Fe single sites.

Conventional macroaggregated albumin (MAA) often fails to accurately simulate the biodistribution of 90Y microspheres in hepatic artery perfusion scintigraphy due to density mismatch. By mineralizing MAA, we developed lightly mineralized MAA (L-MAA) and highly mineralized MAA (H-MAA) with controlled densities, which enable a more accurate simulation of the biodistribution of resin and glass microspheres.

A regioselective rhodium(III)-catalyzed C-H bond naphthylation of weak-coordinating aryl esters with bicyclic olefin compounds has been demonstrated. This present protocol is well compatible with a variety of aryl esters as well as bicyclic olefins. The methodology produced highly valuable ester-functionalized 2-naphthylated products in good to excellent yields. A feasible reaction mechanism involving directing group assisted C–H activation was proposed and supported by competitive experiments and deuterium labelling studies.

A gliding arc plasmatron (GAP) was proposed for efficient degradation of mixed microplastics (MPs) under simplified and adaptable conditions. Complete degradation of MPs can be achieved within 2–4 minutes, with non-hazardous CO₂ as nearly the only gas product. The catalyst-free GAP system, with its simplicity and compatibility with distributed renewable energy supply, offers a sustainable solution for MPs treatment.
