The synthesis, growth and structure of a novel organic third order nonlinear optical (NLO) crystal namely, N,N,N′,N′-tetramethylethylenediammonium-bis(4-nitrophenolate) (TMEDA4NP) is presented.
Self-assembled PEGylated poly(l-valine) hydrogels with combinational α-helix and β-sheet secondary structures represented new biomaterial scaffolds in biomedical fields including but not limited to 3D cell culture.
