Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.

Molecularly Mediated Assembly of Metal Nanoparticles With Multifunctional Interfaces for Selective Detection of Small Gas Molecules

Small, EarlyView.
This work demonstrates a conceptual framework of three types of cooperative interaction pathways in molecularly assembled nanoparticle chemiresistors. Their relative contributions depend on nanoparticle composition, linker chemistry, film architecture, and analyte identity, modulating the effective tunneling barrier (Φ), interparticle spacing (d), and ...

Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

Structural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

American Journal of Medical Genetics Part A, Volume 200, Issue 9, Page 2067-2079, September 2026.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.
