Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering
Advanced Functional Materials, EarlyView.This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,

Pengaruh Jenis Poliol terhadap Pembentukan Poliuretan dari Monomer PEG400 dan MDI
Journal of Mathematical and Fundamental Sciences, 2013 The properties of polyurethane depend largely on building blocks, especially the kind of polyol. Not only pure synthetic compounds but also various natural substances such as saccharides (glucose, fructose, maltose, sucrose) and amylose can be used as ...

Advanced Functional Materials, EarlyView.Bioinspired bromination of a resilin‐derived peptide enables the fabrication of electrospun nanofibrous scaffolds that uniquely combine strain‐stiffening elasticity, proteolytic stability, and antioxidant functionality. These brominated peptide–gelatin hybrids mimic the extensibility of natural elastomers, demonstrating tunable mechanical resilience ...
