Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Secondary add-on IOL implantation for pseudophakic residual ametropia in high myopes – A case series

Indian Journal of Ophthalmology. Case Reports, 2023
High Myopic cataract patients receiving low-powered or negative powered intraocular lenses (IOLs) after phacoemulsification, often have residual hyperopic refractive errors and remain dissatisfied. Implantation of add-on IOL is one of the easy options to

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Complications of laser in situ keratomileusis (LASIK)

Kerala Journal of Ophthalmology
Laser-in-situ-keratomileusis (LASIK) is one of the most commonly done refractive surgeries round the globe. It has become a popular technique of refractive surgery because of lower postoperative discomfort, early visual rehabilitation and decreased post ...

Intraoperative Complications of LASIK and SMILE

, 2022
In parallel to recent advances in laser technology, safety and efficacy of corneal refractive surgery have been significantly improved. For instance, flap-related complications of laser in situ keratomileusis (LASIK) have been significantly decreased ...

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...
