Article Abstract
In situ electron holography is used to observe changes of electric-potential distributions in an amorphous lithium phosphorus oxynitride (LiPON) solid-state electrolyte when different voltages are applied. 2D phase images are simulated by integrating the 3D potential distribution along the electron trajectory through a thin Cu/LiPON/Cu region. Good agreement between experimental and simulated phase distributions is obtained when the influence of the external electric field is taken into account using the 3D boundary-charge method. Based on the precise potential changes, the lithium-ion and lithium-vacancy distributions inside the LiPON layer and electric double layers (EDLs) are inferred. The gradients of the phase drops at the interfaces in relation to EDL widths are discussed.

A CuFeO/NiCo-LDH heterojunction electrochemical sensor (LDH: layered double hydroxide) was developed for the sensitive detection of tetracycline (TC). The sensor was constructed by integrating ZIF-67-derived nanocage NiCo-LDH on nickel foam with CuFeO, forming a p-n heterojunction that enhanced electron transfer and TC adsorption. The sensor exhibited bilinear detection ranges (0.

Accelerating the rate-limiting surface Fe(III)/Fe(II) redox cycling is pivotal for efficient iron-mediated Fenton-like decontamination, yet conventional reductants (e.g., toxic hydroxylamine, thiosulfate) suffer from secondary toxicity, self-quenching, and heavy metal leaching.

Achieving precise control of materials synthesis is a cornerstone of modern manufacturing, driving efficiency, functionality, and device innovation. This review examines the roles of transmission electron microscopy (TEM) and neutron scattering (NS) in advancing our understanding of these processes. TEM offers atomic-scale insights into nucleation, growth, and phase transitions, while NS provides an analysis of reaction pathways, phase evolution, and structural transformations over broader length scales.

To advance the commercial utilization of aqueous electrochemical devices for grid-scale energy storage, it is crucial to address the current limitations related to energy density and cycle stability. Indeed, the lack of high-performance cathodes is still an obstructive issue, not to mention the limited capacities related to the monotonic cation intercalation/deintercalation mechanism. Fortunately, conversion chemistries with redox reactions bring a new dimension, where materials with multiple valence states facilitate multi-electron redox reactions, offering the potential for high-energy-density storage.

Facing the massive energy consumption of over 200 TWh y of chlor-alkali industry, developing high-activity and durable non-precious CER (chlorine evolution reaction) catalysts is urgently needed to address the high overpotentials and suppress the dissolution high-valance metal species. Herein, a carbon quantum dots functionalized trimetallic Fe/Co/Ni spinel oxide nanotube architecture (FCNO@CQDs) is constructed, featuring t-to-π* π-backbonding for dramatically enhanced CER activity and stability. The reverse electron flow from Co d-obritals to the vacant CQDs' π* orbitals can upshift the d-band center for enhanced intermediate adsorption, while stabilizing high-valent Co centers via increased bond order.
