Atmospheric Doping of Stretchable Polymer Semiconductors for Skin Electronics

open access: yesAdvanced Functional Materials, EarlyView.
An atmospheric doping system using oxygen molecules in air as dopants is introduced for stretchable polymer semiconductors. The chemisorbed oxygen molecules act as acceptor, lead to increase not only the hole concentration of the semiconductor film over two orders of magnitude (3.37 × 1017 cm−3) but also electrical properties of the field‐effect ...

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

open access: yesAdvanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.

All‐Material Crosslinked Solid Polymer Electrolytes for High‐Performance and Flexible Lithium Metal Battery

open access: yesAdvanced Functional Materials, EarlyView.
A novel solid polymer electrolyte (SPE) to overcome interface instability in high‐energy‐density lithium metal batteries has been developed. By enhancing ionic conductivity, mechanical elasticity, and adhesion strength through all‐material UV‐crosslinking, the SPE ensures uniform lithium‐ion flow and stable performance—even after bending or cutting ...

Oligohistidine‐Functionalized Single‐Walled Carbon Nanotube‐Guided RNA Delivery to Improve Shoot Regeneration Efficiency in Plant Calli

open access: yesAdvanced Functional Materials, EarlyView.
The pH‐sensitive His6‐SWNTs, which is functionalized with oligohistidine, can deliver STTM396 molecules into callus cells. The STTM396–SWNT complex treatments enhance shoot regeneration efficiency by regulating the miR396‐GRF module in Arabidopsis and tomato calli.

540 Trans oro Pharyngeal Spacer for Inhalers

open access: yesWorld Allergy Organization Journal, 2012
BACKGROUND: Many of the patients suffering from bronchial asthma (BA) and COPD do not use the inhalers properly inspite of adequate education, resulting in inadequate relief. The external spacer (es) with the inhaler needs an inspiratory rate of 25 ltsmt, not portable and costly.
