Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

Polymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Moisture Absorption in Highly Porous Closed‐Cell Polymeric Foams

Polymer Engineering &Science, EarlyView.
The conventional one‐dimensional hindered diffusion model has been extended into a new Void Filling Hindered Diffusion Model. By quantifying the moisture stored within closed‐cell pores, this model successfully captures the distinct absorption behaviors observed across varying foam thicknesses.

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

Small, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...
