A Body Conformal Ultrasound Receiver for Efficient and Stable Wireless Power Transfer in Deep Percutaneous Charging

open access: yesAdvanced Materials, EarlyView.
Implantable devices rely on batteries that demand surgical replacement, posing risks, and financial burdens. Ultrasound energy transfer (US‐ET) offers a revolutionary wireless alternative but struggles with efficiency. The presented dielectric‐ferroelectric‐boosted US‐TENG (US‐TENGDF‐B) is thin, flexible, and biocompatible that provides high‐efficiency

Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells

open access: yesAdvanced Materials, EarlyView.
A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Formulation and Characterization of Novel Ionizable and Cationic Lipid Nanoparticles for the Delivery of Splice‐Switching Oligonucleotides

open access: yesAdvanced Materials, EarlyView.
Lipid nanoparticles (LNPs) of unconventional composition and defined structures are investigated as small oligonucleotide carriers. A composition is identified that outperforms Onpattro in cargo delivery to HeLa cells. The structure of these LNPs resembles a micellar cubic phase not commonly associated with high‐performing LNPs.
