ABSTRACT Stimuli-responsive hydrogels have attracted much interest recently [1]. In this paper, we report a pH- and electrolyte-responsive hydrogel based on a crosslinked poly(aspartic acid). The lightly crosslinked, high molecular weight sodium polyas-partate impart extremely high water absorbency and can be used as a superabsorbent [2], It is derived

Adsorption of Amino Acids, Aspartic Acid, and Lysine onto Iron-Oxide Nanoparticles
, 2016Understanding the adsorption of amino acids (AAs) onto magnetic iron-oxide nanoparticles (SPIONs) is important not only for the preparation of the aqueous suspensions, but also for understanding the interactions at the bionano interface.

The thermal copolymerization of aspartic acid and glutamic acid
Archives of Biochemistry and Biophysics, 1960Abstract Thermal condensation of aspartic acid and glutamic acid yields copolymeric products. In typical reactions for periods of 6 hr. or less, mean molecular weights range from 5000 to 25,000. The products are largely polyimides which are convertible by mildly alkaline treatment to materials which are fully linear peptides.

Oxovanadium(iv) complexes of salicyl-l-aspartic acid and salicylglycyl-l-aspartic acid
Dalton Transactions, 2005The dipeptide and tripeptide analogues salicyl-L-aspartic acid (Sal-L-Asp) and salicylglycyl-L-aspartic acid (SalGly-L-Asp) were synthesized and their protonation and complex formation with V(IV)O2+ were studied in aqueous solution through the use of pH-potentiometry and spectroscopic (UV-Vis, CD and EPR) techniques. The phenolate terminus proved to be
