Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains

open access: yesAdvanced Materials Technologies, EarlyView.
Conventional ophthalmic lens manufacturing discards up to 97% of material through subtractive processes. The Cookie Cutter algorithm extends Fluidic Shaping to arbitrary rim geometries. The framework prescribes a spatially varying boundary height that, under neutral buoyancy and surface tension, shapes curable polymer into spherocylindrical lenses that

Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

open access: yesAdvanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Zinc Chloride–Polyethylene Oxide Gel Polymer Electrolytes for Wearable and Flexible Energy Storage Applications

open access: yesAdvanced Materials Technologies, EarlyView.
We investigate gel polymer electrolyte ZnCl2‐PEO as energy storage materials in flexible electrochemical capacitors, aiming to provide new insights into energy solutions for low‐powered portable electronics. ABSTRACT We prepared and evaluated the properties of hydrated ZnCl2‐Polyethylene oxide (PEO) gel polymer electrolyte (H‐GPE) for flexible ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

open access: yesAdvanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
