Poly(3‐hexylthiophene) (P3HT) is widely shown to have considerable advantages in photovoltaic cells, including excellent electrical performance, but its fragility remains a challenge for material applications and processing of stretchable devices. Herein, high‐molecular‐weight highly regioregular poly(3‐substituted thiophene) with disiloxane moieties the side chains (P3SiT) synthesized. An investigation molecular structure physical properties self‐supported cast films P3SiT reveals flexible...

We propose a near-field optical transducer using triangular antenna and thin film structure (wing) to efficiently generate an near magnetic head. A finite-difference time-domain calculation showed that the was generated at apex of when dimensions wing were optimized for efficient delivery surface plasmon excited on antenna. The calculated light utilization efficiency (ratio between absorbed power in recording medium input power) 8%. temperature distribution medium, field distribution,...

In electronic devices, thermal management, such as heat dissipation, is challenging. Therefore, polymer composites including thermally conductive fillers with high conductivities, low weights, and flexibility processability have attracted attention. particular, a conductivity in the thickness direction via filler alignment important. this study, we aligned isotropic, nanodiamond (ND) using an ice-templating method achieved dimensional stability direction. Notably, was 3 times higher than...

Celluloses have attracted much attention as sustainable and abundant materials. Herein, we focus on nanocomposites based the oxidation-treated nano-sized fibrillated celluloses, namely TOCNs. The silver nanoparticles (AgNPs) were prepared in TOCN aqueous dispersion. Generally, AgNPs are quickly agglomerated after preparation. For inhibition of agglomeration AgNPs, it is required that under chelation TOCN, followed by reduction therein. Therefore, possessed nano-scaled radii aligned along...
