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

open access: yesQuality 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.

Hierarchically Biporous Wick Vapor Chamber With Micro/Nano Condenser for Exceeding 600 W/cm2 Heat Dissipation

open access: yesSmall, EarlyView.
An integrated vapor chamber couples a hierarchically biporous copper wick with a micro/nano‐textured superhydrophobic condenser to form a self‐sustained liquid–vapor loop. The device dissipates extreme heat fluxes above 600 W/cm2, even when the condenser is above the heater, by overcoming the permeability‐capillarity trade‐off in conventional vapor ...

Exploiting Device Deformability for Fluid and Particle Manipulation

open access: yesSmall, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures

open access: yesSmall, EarlyView.
Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

open access: yessteel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of
