Microscale Patterning of Ultrahigh‐Viscosity Metallic‐Polymer Composites via Embedded Droplet Writing

Advanced Functional Materials, EarlyView.
A hybrid additive manufacturing platform integrates direct droplet writing of metallic composite with VAT photopolymerization to fabricate architected soft magnetic composites. This approach enables microscale patterning of high‐viscosity materials for programmable actuators, adaptive fluidic devices, and switchable adhesives, offering tunable ...

The influence of blood glucose level on tear break up time among young adults with diabetes [PDF]

, 2018
It has been reported that diabetics are more likely to develop tear film dysfunction compared to non-diabetics. Even so, there has been very little research reported on the correlation between blood glucose level and quality of tears.

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

Advanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

Advanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

A fully automated dry eye and breakup pattern detection based on deep learning

Journal of King Saud University: Computer and Information Sciences
Dry Eye Disease (DED) is a chronic ocular condition characterized by a high prevalence rate. It arises from an imbalance between tear secretion and the evaporation of the tear film’s aqueous component, leading to tear film instability.
