Hierarchical Conducting Bridging Network for Accelerated Charge Transport and Structural Stabilization of Li‐Mn‐Rich Cathodes

Battery Energy, Volume 5, Issue 4, July 2026.
A hierarchically conducting bridging network (HCBN) addresses the sluggish kinetics and structural instability of lithium‐manganese‐rich oxide cathodes. This 3D architecture ensures electrochemical reaction uniformity and provides mechanical buffering against internal stress.

Semen Quality and DNA Fragmentation After Limited Testicular Sperm Extraction in Non‐Azoospermic Men With ART Failure: A Retrospective Matched Cohort Study

Health Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims Testicular sperm extraction (TESE) is sometimes used in non‐azoospermic men with persistent infertility, particularly in cases of high sperm DNA fragmentation index (DFI) or repeated intracytoplasmic sperm injection (ICSI) failure.

Characterization of Air and Ozone Micro‐Nano Bubbles and Their Impacts on Physicochemical Attributes, Total Phenolic Content, and Natural Microbial Load of Fresh “Fan Retief” Guava During Storage

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT Chlorine‐based water treatment for fresh produce has diverse limitations including the production of disinfectant‐by‐product residue. Thus, this study characterized and investigated the impact of micro‐nano bubble (MNB) water (air and ozone (O3)) on the quality attributes of guava fruit during storage.

Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.
