Heterocyclic nitrogen-containing compounds in hamanatto.

open access: yesJOURNAL OF THE SOCIETY OF BREWING,JAPAN, 1985
香気成分として重要な含窒素環状化合物の浜納豆における種類及び含量を測定した。ジクロロメタンによる直接溶媒抽出法により塩基性抽出画分を調製し, FTD装備のGC及びGC-MS分析により同定定量した。11種類のピラジン, ピリジン, N-メチルピロリドン, ベンゾチアゾール, 2-アセチルピロールが検出された。ピラジン化合物の総含量は629 ppbであった。閾値との比較より, ピラジン化合物が浜納豆の香気に寄与している可能性があることが示唆された。

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...

CORE: Cholesterol Altered Lipid Nanoparticles for Splenic Expression of mRNA Payloads

open access: yesAdvanced Healthcare Materials, EarlyView.
In this paper researchers introduce CORE LNPs, a new class of lipid nanoparticles engineered to redirect mRNA expression away from the liver and into the spleen, a key immune organ. By combining chemical design with computational tools, they created cholesterol analogs that enable precise spleen‐targeted expression, providing greater applications for ...
