Identification of Molecular Fluorophore as a Component of Carbon Dots able to Induce Gelation in a Fluorescent Multivalent-Metal-Ion-Free Alginate Hydrogel
Kasak P.; Danko M.; Zavahir S.; Mrlik M.; Xiong Y.; Yousaf A.B.; Lai W.-F.; Krupa I.; Tkac J.; Rogach A.L.... more authors ... less authors ( Nature Publishing Group , 2019 , Article)We introduce a simple approach to fabricate fluorescent multivalent metal ion-free alginate hydrogels, which can be produced using carbon dots accessible from natural sources (citric acid and L-cysteine). Molecular fluorophore ... -
Morphology analysis
Popelka, A.; Zavahir, S.; Habib, S. ( Elsevier , 2020 , Book chapter)This chapter is dedicated to the surface morphology and topography analyses of various types of polymers in terms of their structural conformations and resulting material structures. The morphology of polymers includes ... -
Polyzwitterionic Hydrogels in Engines Based on the Antipolyelectrolyte Effect and Driven by the Salinity Gradient
Zavahir S.; Krupa I.; Almaadeed S.A.; Tkac J.; Kasak P. ( American Chemical Society , 2019 , Article)In this paper, we propose and investigate an original approach to energy conversion based on polyzwitterionic hydrogels, which exhibit an antipolyelectrolyte effect that enables them to swell in salt water and shrink in ... -
Ti3C2Tx mxene-based light-responsive hydrogel composite for bendable bilayer photoactuator
Zavahir S.; Sobol?iak P.; Krupa I.; Han D.S.; Tkac J.; Kasak P.... more authors ... less authors ( MDPI AG , 2020 , Article)Soft actuators based on hydrogel materials, which can convert light energy directly into mechanical energy, are of the utmost importance, especially with enhancements in device development. However, the hunt for specific ...
