Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Enzyme‐Responsive Porous Scaffolds by Electrospinning Polyalanine

open access: yesMacromolecular Chemistry and Physics, EarlyView.
Sustainably synthesized polyalanine (PAla) was co‐electrospun with poly(ε‐caprolactone) (PCL) to create robust nanofibrous scaffolds. The inclusion of PAla dramatically increased the maximum tensile stress by 399%. These ‘smart’ scaffolds demonstrated selective degradation in the presence of human neutrophil elastase (HNE), pioneering mechanically ...

Fiber Reinforcement of Soft Spider Silk Hydrogels

open access: yesMacromolecular Rapid Communications, EarlyView.
Along the development of matrices for biomedical applications, precise tuning of the biomaterial to interact with specific cell types/tissues is essential. The fabrication of fiber mesh‐reinforced soft hydrogels made of recombinant spider silk proteins allows for the adjustment of mechanical properties and hydrogel porosity, leading to improved cell ...

Synthesis of Telechelic‐Type Polypeptides Functionalized with Aromatic Units and the Characterization of Their Structures and Thermal Properties

open access: yesMacromolecular Rapid Communications, EarlyView.
Polypeptide chains were extended from both ends of aromatic diamines by chemoenzymatic polymerization, resulting in the synthesis of telechelic polyglycines (TPG) and polyalanines (TPA). These telechelic polymers assembled into branched nanofibrils through π‐π stacking of aromatic rings, with the polymer backbones bent at the aromatic unit.
