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

Mechanics of damping for fiber composite laminates including hygro-thermal effects [PDF]
An integrated mechanics theory was developed for the modeling of composite damping from the micromechanics to the laminate level. Simplified, design oriented equations based on hysteretic damping are presented for on-axis plies, off-axis plies, and ...

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

ABSTRACT The incorporation of nanocellulose‐doped insulating paper into the material composition of a given structure has been demonstrated to enhance the material’s mechanical properties and retard the development of cracks. However, the effects of different length‐to‐diameter ratios of nanocellulose are different.
