Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

(3+1)D Printing of Core–Clad Waveguide by Two‐Photon Polymerization
Low‐loss, single‐mode core–clad optical waveguides are fabricated using a novel (3+1)D multiphoton polymerization technique in a hybrid resin. Precise laser power control and multi‐pass exposure enable refractive index engineering and reduce scattering. Raman spectroscopy confirms the correlation between polymerization and index change.

This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber
Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for
