Optical characterisation and vision quality assessment of two myopia control contact lenses

Ophthalmic and Physiological Optics, Volume 45, Issue 5, Page 1142-1150, July 2025.
Abstract Purpose This investigation examined the image and vision quality of two commercially available daily disposable myopia control soft contact lenses. Methods Wavefront errors were measured with an SHS Ophthalmic aberrometer for two myopia control soft contact lenses: a coaxially designed dual‐focus lens (omafilcon A, CooperVision MiSight® 1 day,

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

Advanced Materials Technologies, Volume 10, Issue 11, June 5, 2025.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

Shape‐Selective Molecular Separations Enabled by Rigid and Interconnected Confinements Engineered in Conjugated Microporous Polymer Membranes

Advanced Science, Volume 12, Issue 22, June 12, 2025.
Conjugated microporous polymer membranes with narrowly distributed network pores are prepared by diffusion‐modulated electropolymerization. This approach precisely controls the monomer diffusion and coupling processes, regulating the crosslinking degree to prevent broad aggregate pores and microporous defects.
