Fracture of the Passive Film on Reinforcing Steel in Concrete Under Mechanical Loading
Materials and Corrosion, EarlyView.Bending load induces a flexural crack in reinforced concrete specimen. Above the critical load inducing crack, a macro cell corrosion current is recorded by steel coupons embedded in the concrete. The macro cell current corresponds to the rupture of the passive film. ABSTRACT This study investigates the fracture of the passive film on reinforcing steel

Macromolecular Rapid Communications, EarlyView.We employ freeform printing of thermo‐responsive poly(2‐oxazoline) to directly fabricate suspended sacrificial vascular templates within Organ‐on‐a‐chip devices. This enables circular, perfusable channels down to 200 µm without post‐processing.

Advances in GPCRs Associated With Wnt Signaling Within the Auditory System
Medicine Bulletin, EarlyView.ABSTRACT G protein‐coupled receptors (GPCRs) that interact with the Wnt signaling pathway are pivotal for auditory system homeostasis, as they orchestrate inner ear development, hair cell (HC) regeneration, and hearing preservation. Frizzled (FZD) receptors, the core Wnt‐related GPCRs, bind Wnt ligands and co‐receptors (e.g., LRP5/6) to activate both ...

Anisotropic Initial Damage and Its Effect on Tensile Response of Plain Concrete
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Damage is often described as isotropic, implying that a scalar value describes its initial state. However, the prior micro‐cracking pattern at points of an existing building, that is, the initial damage, may be oriented by a preload. The degradation of the Volume Element due to oriented preloads shall be described as anisotropic and ...

Investigation of the flexural properties of reinforced concrete beams strengthened by externally bonded steel plates. [PDF]
, 1980 It is sometimes necessary to strengthen in situ concrete structures. Externally bonded plate reinforcement has been successfully applied to structures with subsequent satisfactory performance.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.
