“…[41][42][43] Specifically, during the electrochemical deposition, the electrical force applied to the ITO electrode first facilitated the formation of gold seeds while TWEEN-20, a non-ionic surfactant, inhibited the diffusion of gold ions onto the seed surface. [44,45] This phenomenon ultimately delays the overall deposition process. To prove this hypothesis, we varied the concentrations of TWEEN-20 during electrochemical deposition and monitored the changes in the morphology of gold nanoparticles (Figure 1a; Figure S1a,b, Supporting Information).…”

Deoxyribonuclease‐I (DNase‐I), a representative endonuclease, is an important biomarker for the diagnosis of infectious diseases and cancer progression. However, enzymatic activity decreases rapidly ex vivo, which highlights the need for precise on‐site detection of DNase‐I. Here, a localized surface plasmon resonance (LSPR) biosensor that enables the simple and rapid detection of DNase‐I is reported. Moreover, a novel technique named electrochemical deposition and mild thermal annealing (EDMIT) is applied to overcome signal variations. By taking advantage of the low adhesion of gold clusters on indium tin oxide substrates, both the uniformity and sphericity of gold nanoparticles are increased under mild thermal annealing conditions via coalescence and Ostwald ripening. This ultimately results in an approximately 15‐fold decrease in LSPR signal variations. The linear range of the fabricated sensor is 20–1000 ng mL−1 with a limit of detection (LOD) of 127.25 pg mL−1, as demonstrated by spectral absorbance analyses. The fabricated LSPR sensor stably measured DNase‐I concentrations from samples collected from both an inflammatory bowel disease (IBD) mouse model, as well as human patients with severe COVID‐19 symptoms. Therefore, the proposed LSPR sensor fabricated via the EDMIT method can be used for early diagnosis of other infectious diseases.

“…Electrodeposition is an inexpensive, simple, and binder‐free method for the preparation of manganese‐based materials. Owing to its high selectivity, high efficiency, low byproducts, and easily adjustable current and voltage for the synthesis process, it has been receiving more and more attention in recent years 31–33 . Moreover, because the material synthesized by this method has good adhesion to the collector fluid, there is no need to add adhesives and conductive agents to the collector fluid 34 .…”

Regeneration of spent lithium manganate into cation‐doped and oxygen‐deficient MnO₂ cathodes toward ultralong lifespan and wide‐temperature‐tolerant aqueous Zn‐ion batteries

Manganese-based compounds have been regarded as the most promising cathode materials for rechargeable aqueous zinc-ion batteries (AZIBs) due to their high theoretical capacity. Unfortunately, aqueous Zn-manganese dioxide (MnO 2 ) batteries have poor cycling stability and are unstable across a wide temperature range, severely limiting their commercial application. Cationic preinsertion and defect engineering might increase active sites and electron delocalization, which render the high mobility of the MnO 2 cathode when operated across a wide temperature range. In the present work, for the first time, we successfully introduced lithium ions and ammonium ions into manganese dioxide (LNMO d @CC) by an electrodeposition combined with low-temperature calcination route using spent lithium manganate as a raw material. The obtained LNMO d @CC exhibits a high reversible capacity (300 mAh g −1 at 1 A g −1 ) and an outstanding long lifespan of over 9000 cycles at 5.0 A g −1 with a capacity of 152 mAh g −1 , which is significant for both the high-value recycling of spent lithium manganate batteries and highperformance modification for MnO 2 cathodes. Besides, the LNMO d @CC demonstrates excellent electrochemical performance across wide temperature
