The Journal of the Society of Chemical Industry, Japan, 1962 ポリエチレンテレフタレートを溶融点以下の高温で固体の状態で減圧加熱し,重縮合反応が進行することを確認し,得られた重合物が通常の溶融重合によって得られたものとほとんど変らぬことを分別によって確かめ,既報で報告した熱風中固相での160～180℃での急激な化学的挙動の変化が,分解反応でなく,重縮合反応の形で急激に速くなることが見出された。また予想したように,チップ状から粉末状に表面積を増すことによって,反応速度がいちじるしく大きくなることを確認し,EG拡散が律速段階であろうと推論した。また,この方法で溶融法で得られにくい高重合度のものが得られる。

A Ceramic Network for Hybrid Solid Electrolyte Lithium Metal Batteries
Advanced Science, EarlyView.An in‐plane aligned Ta‐LLZO ceramic network exhibits superior performance compared to conventional fillers, including single ceramic fibers and particles. The tortuosity within the polymeric phase of hybrid solid electrolytes is identified as a key parameter governing lithium‐ion transport pathways and dendrite suppression.

Advanced Science, EarlyView.A universal paradigm resolves the trade‐off between ambient stability and barrier properties in organic persistent luminescent (OPL) polymers. By interlocking chromophores within a high‐barrier MXD6 matrix, we achieved no Pre‐photoactivation OPLs with exceptional long‐term stability in water.

Advanced Science, EarlyView.A regenerative molecular sensing platform that co‐localizes surface‐enhanced Raman spectroscopy (SERS) sensing and nanocavitation‐based actuation. Femtosecond‐laser triggered nanocavitation produces thermomechanical forces to locally regenerate SERS‐active nanogaps in protein‐rich biofluids while preserving optical performance.

Biodegradable Acoustic Targeting for Ultrasound‐Supported Gene Therapy (BATUS) in Glioblastoma
Advanced Science, EarlyView.ABSTRACT Glioblastoma (GBM) remains one of the most challenging brain malignancies due to the restrictive nature of the blood–brain barrier (BBB), which severely limits effective drug and gene delivery. To overcome this, we introduce Biodegradable Acoustic Targeting for Ultrasound‐Supported Gene Therapy (BATUS), a modular platform that enables safe ...

Gel‐Amin for Improving Extracellular Recordings of Cardiomyocytes in a 3D Microphysiological System
Advanced Electronic Materials, EarlyView.This work combines a conductive collagen‐based hydrogel with a laser‐cut and assembly technique to fabricate microphysiological systems that improve extracellular recordings of cardiomyocytes in 3D on microelectrode arrays. The inclusion of choline acrylate into GelMA imparts a higher electrical conductivity and improves the signal‐to‐noise ratio of on‐
