A rechargeable ZAB was assembled using a NiCo<sub>2</sub>O<sub>4</sub>3DOM spinel displaying an open circuit potential of 1.44 V, power density 101 mW cm<sup>−2</sup>, and high durability during charge/discharge cycling (being operated for 21 h).
In this work, atomically substituted three-dimensionally ordered macroporous (3DOM) spinels based on Co and Mn (MnCo2O4 CoMn2O4) were synthetized used as cathodic electrocatalysts in a primary Zn-air battery. Scanning/transmission electron microscopy images show 3DOM structure for both materials. Skeleton sizes of 114.4 140.8 nm surface areas 65.3 74.6 m2 g-1 found MnCo2O4 CoMn2O4, respectively. The increase area higher presence Mn3+ Mn4+ species the CoMn2O4 material improved battery...
The use of three-dimensional flow-through nanoporous electrodes and the merging a air-breathing cathode were explored successfully applied in formic acid nanofluidic fuel cell. effects concentration, reaction stoichiometry catalyst mass loading investigated, resulting power densities ranging from 28 to 100 mW cm(-2).

Defects and interface engineering in layered double hydroxides (LDH) are crucial for the rational search functional electrocatalysts. Despite known enhancement of LDH activity by oxygen vacancies (Ov), a formal exploration how vacancy content influences electrocatalytic properties is lacking. Herein, density theory (DFT) calculations were employed to investigate impact Ov (1–5%) on electronic structure, NiFe LDH, coupling with heteroatom-doped carbon. Calculations revealed that states...
Our work describes the green synthesis of silver sulfide nanoparticles (Ag2S NPs) and their formulation into polycaprolactone fibers (PCL), aiming to improve multifunctional biological performance PCL membranes as scaffolds. For this purpose, an extract rosemary (Salvia rosmarinus) was employed a reducing agent for Ag2S NPs, obtaining irregular NPs clusters 5-60 nm, with characteristic SPR absorption at 369 nm. successfully incorporated by electrospinning using heparin (HEP)...
The search for cost‐effective, high‐performance bifunctional catalysts Zn‐air batteries (ZABs) requires extensive research into precious‐metal‐free materials. This study provides insight the synergy between nickel cobaltite and P,N‐doped carbon modified through interface engineering by inducing oxygen vacancies in spinel non‐metallic heteroatoms material. NiCo2O4 with various vacancy levels was synthesized via an ethylene glycol‐assisted solvothermal route. resulted significant changes...
The modification of catalytic activity through the use metallic promoters is a key strategy for optimizing performance, as electronic factors play crucial role in regulating behavior.

A good correlation...
Solid polymer electrolytes (SPEs) are gaining attention as viable alternatives to traditional aqueous in zinc–air batteries (ZABs), owing their enhanced performance and stability. In this study, anion-exchange solid (A-SPEs) were synthesized via electrophilic aromatic substitution reactions. Thin films prepared using the solvent casting method characterized proton nuclear magnetic resonance (¹H-NMR), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA). The...
A membraneless nanofluidic fuel cell with flow-through electrodes that works several fuels (individually or mixed): methanol, ethanol, glycerol and ethylene-glycol in alkaline media is presented.

Well-ordered, homogenous cube-shaped highly ordered Pd, without other geometries, was obtained by chemical reduction in aqueous media employing ascorbic acid, polyvinylpyrrolidone and sodium bromide as the reducing agent, surfactant additive, respectively. The X-ray diffraction (XRD) patterns exhibited a face-centred cubic structure with an average crystallite size of 11.5 nm. Transmission electron microscopy (TEM) images showed homogeneous distribution Pd nanoparticles (namely nanocubes)...
