Reaction of Silk Fibroin with Diazomethane

Textile Research, 1940
The reactive groups in silk are intimately related to the absorp tion of moisture, acids, alkalies, or dyes, and to physical properties such as extensibility and tensile strength. A large proportion of these gorups are present in silk fibroin in the form of hydroxyl groups of the amino acid tyrosine.

Biomimetic self-assembly of tetrapeptides into fibrillar networks and organogels [PDF]

, 2008
The self-assembly features of a family of tetrapeptides inspired in silk structure are presented. An exhaustive study of the influence of the terminal alkyl chain length in this process is undertaken. Scanning electron microscopy (SEM), wide-angle X-ray

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Thiolated Polymers in 3D Bioprinting: Control of Gelation

Advanced Materials, EarlyView.
Thiolated polymers are established as programmable bioinks for 3D bioprinting, integrating versatile crosslinking chemistries with redox‐responsive control. This work demonstrates how molecular design and external triggers define gelation kinetics, printability windows, and structural fidelity, enabling stable, high‐resolution constructs and advancing ...

Macroporous Silk Fibroin Cryogels

Biomacromolecules, 2013
Silk fibroin cryogels with remarkable properties were obtained from frozen fibroin solutions (4.2-12.6%) at subzero temperatures between -5 and -22 °C. This was achieved by the addition of ethylene glycol diglycidyl ether (EGDE) into the cryogelation system.
