In this work, a fabrication process for implantable electrodes using a Cyclic Olefin Copolymer (COC) substrate and a SU-8 passivation layer was presented. COC and SU-8 were shown to be suitable for implantable neural electrodes due to their biocompatibility, chemical resistance, and thermal stability. The electrodes were successfully patterned on the COC film, and the SU-8 passivation layer was coated while maintaining site-opened via photolithography. The photocrosslinking lamination of the substrate and passivation layer was used to produce electrodes with fine line widths of 20um without applying heat.

Organic nucleophile-assisted natural seawater electrolysis has emerged as a promising strategy for green hydrogen production by significantly reducing energy consumption. Among Ni-based electrocatalysts, NiMoO has drawn attention for its activity in both oxygen evolution reaction (OER) and urea oxidation reaction (UOR). However, its practical application is hindered by severe surface passivation, particularly at industrial current densities (e.

The introduction of two-dimensional (2D) perovskite layers on top of three-dimensional (3D) perovskite films enhances the performance and stability of perovskite solar cells (PSCs). However, the electronic effect of the spacer cation and the quality of the 2D capping layer are critical factors in achieving the required results. In this study, we compared two fluorinated salts: 4-(trifluoromethyl) benzamidine hydrochloride (4TF-BA·HCl) and 4-fluorobenzamidine hydrochloride (4F-BA·HCl) to engineer the 3D/2D perovskite films.

Quantum dots (QDs) converted to micro light-emitting diodes (LEDs) have emerged as a promising technology for next-generation display devices. However, their commercial application has been hindered by the susceptibility of QDs to photodegradation when directly exposed to an open environment. Here, we develop functional ligand zinc bis[2-(methacryloyloxy)ethyl] phosphate (Zn(BMEP)) to passivate QD surface anions through a phosphine-mediated surface reaction.

Perovskites have a large number of intrinsic defects and interface defects, which often lead to non-radiative recombination, and thus affect the efficiency of perovskite solar cells (PSCs). Introducing appropriate passivators between the perovskite layer and the transport layer for defect modification is crucial for improving the performance of PSCs. Herein, two positional isomers, 1-naphthylmethylammonium iodide (NMAI) and 2-naphthylmethylammonium iodide (NYAI) are designed.

Anode-free sulfide-based all-solid-state lithium metal batteries (ASSLMBs), which eliminate the need for a lithium metal anode during fabrication, offer superior energy density, enhanced safety, and simplified manufacturing. Their performance is largely influenced by the interfacial properties of the current collectors. Although previous studies have investigated the degradation of sulfide electrolytes on commonly used copper (Cu) and stainless steel (SS) current collectors, the impact of spontaneously formed surface oxides, such as copper oxide (CuO/CuO) and chromium oxide (CrO), on interfacial stability remains underexplored.
