Summary: Sluggish kinetics and poor structural stability are two main obstacles in the exploration of transition metal selenides (TMSs) for supercapacitors. In this study, a core-shell cobalt iron selenide (CoFe2Se4) @ cobalt nickel carbonate hydroxide (CoNi-CH) heterostructure was directly fabricated on carbon cloth. The heterostructure combines the highly conductive CoFe2Se4 for rapid electron transfer and the highly electroactive CoNi-CH for multiple redox reactions. The CoFe2Se4@CoNi-CH electrode exhibits increased specific capacity and enhanced rate capability compared to pure CoFe2Se4 and CoNi-CH. Furthermore, a hybrid supercapacitor utilizing the CoFe2Se4@CoNi-CH cathode and porous carbon anode achieves a high energy density and excellent durability.

Summary: In this study, ZnO/NiO@NC electrode material was prepared using polyvinylpyrrolidone (PVP) as a structural guide and carbon source, and annealed under an N2 atmosphere to obtain an oxygen-vacancy-rich ZnO/NiO@N-doped carbon shell (ZnO/NiO@NC). The ZnO/NiO@NC electrode exhibited the highest specific capacitance (860.00 F/g), longer charge/discharge time, and lower impedance compared to other materials at a current density of 0.5 A/g. The excellent electrochemical performance can be attributed to the formation of an effective p-n heterostructure, surface oxygen vacancies, and a rich mesoporous structure, as well as the excellent electrical conductivity of the N-doped carbon shell.

Summary: In this study, a highly sensitive biosensor system for detecting thiamethoxam residue was developed based on aptamer technology. Through 15 rounds of screening, aptamer libraries from the 5th and 9th rounds showed high affinity using the capture method. Four candidate aptamers were obtained and the aptamer Thi-5R-18 from the 5th round showed the highest affinity. A colorimetric aptasensor using Thi-5R-18 achieved an ultralow detection limit of 0.37 nM and could quantitatively detect thiamethoxam on tea leaves.

Summary: A high-performance Surface-Enhanced Raman Spectroscopy (SERS) analytical platform was developed in this study by self-assembling gold nanoparticles (AuNPs) at the three-phase liquid-liquid interface. The reduced interparticle gap resulted in dense SERS 'hot spots' with an average gap of less than 3 nm, allowing for highly sensitive detection. Despite the reduced integration time and mapping face sweep, the homogeneity of the self-assembled nanoparticle arrays was maintained. This improved high-throughput fabrication holds great promise for sensitive and reliable chemical contaminant monitoring using SERS.

Summary: Tin shows promising potential for aqueous batteries due to its multiple electron reactions, high corrosion resistance, large hydrogen overpotential, and excellent environmental compatibility. However, the efficient alkaline tin plating/stripping process has not been achieved due to high thermodynamic barrier and poor electrochemical kinetics. In this study, a highly reversible stannite-ion electrochemistry was demonstrated for the first time, leading to the development of a novel paradigm of high-energy Sn-based aqueous batteries. The alkaline tin anode exhibited low potential, high specific capacity, superb rate capability, and excellent cycling durability, which proves the feasibility of the alkaline Sn metal anode and suggests the potential of high-energy Sn-based aqueous batteries for safe, reliable, and affordable energy storage.

Summary: Metal-organic framework (MOF) compounds form highly ordered periodic porous networks by connecting metal ions or clusters with organic ligands. With high porosity, large surface area, and controllable pore size, MOFs are widely used in gas storage, catalysis, adsorption, and separation. Incorporating MOFs into SERS substrates improves sensitivity and prevents aggregation of nanoparticles. This review discusses three methods of preparing MOF-based SERS substrates and explores their applications in biosensing, environment, gases, and medical treatments. The current status and prospects of MOF-based SERS analysis are summarized.
