Living organisms growth and release immobilized in an assembled dipeptide hydrogel.

Self-assembled dipeptide hydrogel provides three-dimensional networks through noncovalent interactions for the embedment and the release of multiple biocomponents as well as for the growth of live cells. Here we demonstrate that Caenorhabditis elegans (C. elegans) as model organisms can be immobilized with significant vital signs in N-fluorenylmethoxycarbonyl diphenylalanine (Fmoc-FF) dipeptide hydrogel.

Efficient recovery of bisphenol A from aqueous solution using KCO activated carbon derived from starch-based polyurethane.

Endocrine-disrupting compounds (EDCs) are increasingly polluting water, making it of practical value to develop novel desirable adsorbents for removing these pollutants from wastewater. Here, a simple cross-linking strategy combined with gentle chemical activation was demonstrated to prepare starch polyurethane-activated carbon (STPU-AC) for adsorbing BPA in water. The adsorbents were characterized by various techniques such as FTIR, XPS, Raman, BET, SEM, and zeta potential, and their adsorption properties were investigated comprehensively.
