Sono‐Anatomy and Histology of the Deep Fasciae in the Upper Limb

Journal of Ultrasound in Medicine, EarlyView.
The deep fascia of the upper limb represents a pivotal anatomical structure essential for effective force transmission, dynamic compartmentalization and musculoskeletal stability. Its composition (rich in type I collagen fibers) enables both mechanical resilience and functional adaptability, crucial for the upper limb's complex movements.

Corrosion‐Protection of T122 Steel Using g‐C3N5‐Embedded Epoxy Coatings

Materials and Corrosion, EarlyView.
Study evaluates g‐C3N5 (CN) reinforced epoxy coatings on T122 steel in NaCl and H2SO4. Electrochemical tests revealed that 2% loading maximizes corrosion resistance by blocking pores and limiting ion diffusion, increasing Rp and Rn. Optimized CN content enhances epoxy coating performance overall system durability material. ABSTRACT Corrosion‐protection

A Technology‐First Framework for SDG Implementation in Carbon‐Based Economies: Empirical Evidence and Policy Implications

Sustainable Development, EarlyView.
ABSTRACT Only 17% of Sustainable Development Goal indicators are globally on track, yet the structural conditions explaining this failure remain inadequately theorised for fossil‐fuel‐dependent economies. This study develops and empirically tests a four‐layer loop framework of Technology, Well‐being, Social Equity, and Sustainability closing through ...
