Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

Materials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Recent Advances in Cryogel Applications for Musculoskeletal Regeneration

Medicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Nested‐Sphere Structure Stabilizes High‐Performance Lithium‐Rich Manganese‐Based Oxide Cathodes

National Materials, EarlyView.
A nested‐sphere architecture is engineered in LMO by tuning oxygen partial pressure during sintering. This structure features internal buffer spaces, which effectively accommodate volume changes and dissipate localized stress during charge–discharge. The cathode delivers 308 mAh g−1 at 0.1°C and achieves 93.4% voltage retention after 300 cycles at 1°C.

Sanitary risk in the handling of home‐prepared enteral formulations: A cross‐sectional assessment of microbiological contamination and food safety

Nutrition in Clinical Practice, EarlyView.
Abstract Background Studies show increased use of home enteral nutrition (HEN) owing to its benefits. However, knowledge about the sanitary risks of handling home‐prepared formulas remains limited despite their high contamination rates. This study aimed to assess the sanitary risks in the handling of home‐prepared enteral formulations by analyzing ...
