Energy confinement and transport of H-mode plasmas in tokamak

open access: yesEnergy confinement and transport of H-mode plasmas in tokamak
Hモードプラズマのエネルギー閉じ込め特性のプラズマ密度依存性,プラズマ形状効果,不純物ガス導入の効果及びコアプラズマの熱流束の影響をそれぞれ解明した。また国際マルチマシンデータベースを用いて、JT-60UにおけるHモードの閉じ込め特性の他装置との比較を行った。高密度領域では、ペデスタル肩の温度の低下に伴って、コア部の温度勾配特性長を一定に保つように中心部温度が低下した。高三角度化及びアルゴン注入によるHモードについても、ペデスタル温度の上昇が炉心プラズマの閉じ込めを決定することがわかった。また炉心プラズマの熱流束が増加しても、温度勾配特性長を一定に保つように熱拡散係数が増大した。国際マルチマシンデータベースを用いた検討では、高三角度化が将来のトカマク炉において適した運転手法であることを示した。

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Self‐Hybridized Exciton‐Polariton Photodetectors From Layered Metal‐Organic Chalcogenolates

open access: yesAdvanced Functional Materials, EarlyView.
Self‐hybridized exciton‐polariton photodetectors are demonstrated using high refractive index mithrene, eliminating the need for top mirrors. This simplified architecture enables tunable sub‐bandgap photodetection via lower exciton‐polariton states and enhanced carrier transport through ultrafast polariton group velocities.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.
