Experimental and computational methods for studying relaxation of aluminosilicate glasses: A review

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 6, June 2025.
Abstract Relaxation plays a critical role in all glasses, especially those that undergo heat treatments for industrial applications. However, the fundamental mechanisms of relaxation are still poorly understood, especially in industrially relevant glasses such as aluminosilicate systems.

Crack paths under mixed mode loading [PDF]

open access: yes, 2008
Long fatigue cracks that initially experience mixed mode displacements usually change direction in response to cyclic elastic stresses. Eventually the cracks tend to orient themselves into a pure mode I condition, but the path that they take can be ...

Efficient Autonomous Dew Water Harvesting by Laser Micropatterning: Superhydrophilic and High Emissivity Robust Grooved Metallic Surfaces Enabling Filmwise Condensation and Radiative Cooling

open access: yesAdvanced Materials, Volume 37, Issue 18, May 5, 2025.
Laser micropatterning is presented as a promising technology in the search for autonomous dew water harvesting materials. Laser‐grooved metallic surfaces achieve simultaneously high infrared emissivity and superhydrophilicity, which gives them self‐cooling properties under atmospheric radiative deficit and the ability to condense water in an efficient ...

Better 3D Inspection with Structured Illumination Part I: Signal Formation and Precision

open access: yes, 2015
For quality control in the factory, 3D-metrology faces increasing demands for high precision and for more space-bandwidth-speed-product SBSP (number of 3D-points/sec). As a potential solution, we will discuss Structured-Illumination Microscopy (SIM).

Orbital-angular-momentum dependent speckles for spatial mode sorting and multiplexed data transmission [PDF]

open access: yesarXiv, 2023
Characterizing the orbital angular momentum (OAM) of a vortex beam is critically important for OAM-encoded data transfer. However, in typical OAM-based applications where vortex beams transmit through diffusers, the accompanying scattering effect tends to be either deliberately prevented, or characterized and then modulated actively based on complex ...
