Pectin/PVA and pectin-MgO/PVA films: Preparation, characterization and biodegradation studies

Heliyon, 2023
There is a great demand to replace non-renewable materials with eco-friendly renewable materials for many applications in recent times. In the present study, such an attempt was made to substitute synthetic polymer-based films used for food packaging applications with films prepared out of renewable materials derived from waste.

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

Advanced Functional Materials, EarlyView.
A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).
