^|^zeta;-Potential of Polyvinyl Alcohol Fibers
Kobunshi Kagaku, 1958 ピニロンCのアンモニヤおよびエチレンジアミンによるアミノ化繊維, 熱処理PVA繊維のアミノアルデハイドジエチルアセタールによるアミノ化繊維のζ-電位を前報までにおいて述べた方法に準じて測定した。これらの繊維は一般に純水中で負の電位を示し, 相当量のHClを結合して電位は0となり, さらにHCl結合量, 水溶液中のHCl濃度が大となると正の電位を示す。しかし繊維のアミノ基含有率, 膨潤度によりHCl水溶液中のζ-電位は変化する。ビニロンCのアミノ化繊維は架橋結合のため膨潤度は小であるにかかわらず正の電位は小である。これらの結果は繊維の非晶部分に存在する解離電荷と吸着アニオンのζ-電位に及ぼす効果について以前の考察に従って理解される。

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors
Advanced Materials, EarlyView.A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

MJERENJE I PRIMJENA ZETA-POTENCIJALA
Rudarsko-geološko-naftni zbornik, 1992 Elektrokinetički ili zeta-potencijal važan je parametar dvojnog električnog sloja i predstavlja jednoznačnu karakteristiku električnih svojstava na kontaktu faza čvrsto-tekuće i tekuće-plinovito. U radu su opisane elektrokinetičke pojave koje pri tom kontaktu nastaju, kao i metode mjerenja potencijala. Prikazane su promjene vrijednosti zeta-potencijala

Advanced Materials, EarlyView.Oppositely charged single enzyme nanogels (SENs) phase‐separate into bi‐enzymatic coacervate microdroplets, acting as both scaffold and functional units. By tuning SEN ratios, these coacervates create specific microenvironments that enable selective small‐molecule enrichment and efficient intermediate diffusion.

THE INFLUENCE OF MODACRYL IN COTTON SAMPLES ON ZETA POTENTIAL
, 2011 Potencial zeta je eksperimentalno določljiva veličina in je rezultat delovanja elektrokinetičnih pojavov. Nanaša se na spremembo potenciala na strižni površini med premikajočim in mirujočim delom difuzne dvojne plasti.
