Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

Advanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|

Investigating the improvement of Degradation Resistant with the Addition of SDBS Anionic Surfactant to PEO polymer

MATEC Web of Conferences, 2018
Polyethylene Oxide (PEO) is one of the most common drag reduction agents. However, its ability to reduce drag in turbulent flow decreases with the time due to the degradation of its molecules.

Potentiometric Determination of Anionic Surfactants in Formulations Containing Cocoamidopropyl Betaine

International Journal of Electrochemical Science, 2012
The application of surfactant sensor based on hexadecyltrioctadecylammonium tetraphenylborate (HTA-TPB) for the potentiometric titration of anionic surfactant (SLES) in the presence of amphoteric surfactant (CAPB) is described.

Separation of cationic surfactants from a large amount of anionic surfactants with anionic exchange.

BUNSEKI KAGAKU, 1984
陽イオン界面活性剤の定量にはオレンジIIなどの陰イオン性色素とのイオン会合体抽出による吸光光度法があるが,試料中に陰イオン界面活性剤が共存する場合は,これが定量を妨害するため.あらかじめ除去する必要がある.著者らは,陰イオン交換樹脂によりこれを吸着除去する方法を検討し,良好な結果を得た.アンバーライトIRA-401のCl型樹脂15mlをガラス管(内径12mm,長さ250mm)に詰めて陰イオン交換樹脂カラムとし,これに流速1ml/minで試料を水溶液のまま通し,その後50%メタノール水溶液で洗浄すると,陰イオン界面活性剤は陰イオン交換樹脂に完全に吸着され,陽イオン界面活性剤は流出液中に分離される.これをオレンジIIを用いる吸光光度法(以下オレンジII法とする)によって定量する.本法により ...

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Potentiometric Surfactant Sensor with a Pt-Doped Acid-Activated Multi-Walled Carbon Nanotube-Based Ionophore Nanocomposite

Sensors
Two new surfactant sensors were developed by synthesizing Pt-doped acid-activated multi-walled carbon nanotubes (Pt@MWCNTs). Two different ionophores using Pt@MWCNTs, a new plasticizer, and (a) cationic surfactant 1,3-dihexadecyl-1H-benzo[d]imidazol-3 ...

Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Physicochemical Reinforcement Unlocks Sterilization‐Stable Anisotropic Hydrogels for Cell‐Compatible Mock Arteries

Advanced Healthcare Materials, EarlyView.
ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)
