Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Phase Transformations from Nanocrystalline to Amorphous (Zr₇₀Ni₂₅Al₅)_100-xW_x (x; 0, 2, 10, 20, 35 at. %) and Subsequent Consolidation

Nanomaterials, 2021
Glasses, which date back to about 2500 BC, originated in Mesopotamia and were later brought to Egypt in approximately 1450 BC. In contrast to the long-range order materials (crystalline materials), the atoms and molecules of glasses, which are ...

Mechanical Alloying Effect in Immiscible Cu-Based Alloy Systems. [PDF]

Journal of Korean Powder Metallurgy Institute, 2003
The mechanical alloying effect has been studied on the three Cu-based alloy systems with a positive heat of mixing. The extended bcc solid solution has been formed in the Cu-V system and an amorphous phase in the Cu-Ta system. However, it is round that a mixture of nanocrystalline Cu and Mo Is formed in the Cu-Mo system.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Progress of compatibilization methods in polymer blends

Cailiao gongcheng, 2019
Compatibilization of immiscible polymer blends is by far the most general and efficient strategy to convert multiphase polymer blends with poor miscibility into high performance polymer alloys. The concept and necessity of compatibilization of immiscible

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Wire-arc directed energy depositing high-ductility Cu-10Fe immiscible alloy with a hierarchical microstructure

Smart Materials in Manufacturing
In this work, a thin-wall Cu-10Fe (10 wt%) immiscible alloy component is fabricated by wire-arc directed energy deposition (WA-DED), leveraging the high energy absorption of the electric arc for copper alloys and its high deposition rate.
