Fractal Anatomy of Human Organs: A Narrative Review of Structure, Function, and Clinical Perspectives

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Fractal geometry describes complex, self‐similar patterns that repeat across spatial scales and is increasingly recognized as relevant in anatomical research. Indeed, the fractal organization is consistently observed in respiratory, cardiovascular, gastrointestinal, nervous, renal, hepatic, and dermatological systems.

Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

open access: yesCarbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Electronic Modulation of Pt Nanoparticles Induced by Defective TiN Promotes Highly Efficient Hydrogen Evolution

open access: yesCarbon Energy, EarlyView.
A nonequilibrium high‐temperature shock method was used to load Pt nanoparticles onto nitrogen vacancy‐rich TiN, enabling strong EMSI modulation. The Pt@TiN‐VN catalyst shows high HER activity (15.99 A mgPₜ⁻¹ at 100 mV) and 60‐h stability. Nitrogen vacancies optimize charge transfer and Pt–H bonding, offering insights into defect‐engineered ...
