Modification of Graphitic Carbon Nitride with Hydrogen Peroxide
Nanomaterials, 2020 Graphitic carbon nitride (GCN) was synthetized by heating melamine and then it was thermally exfoliated for 1–3 h in air. Both bulk and exfoliated GCN nanomaterials were treated in the 10–30% aqueous solutions of H2O2 for us to study their modification ...

New fluorescent pH sensors based on covalently linkable PET rhodamines [PDF]
, 2012 A new class of rhodamines for the application as indicator dyes in fluorescent pH sensors is presented. Their pH-sensitivity derives from photoinduced electron transfer between non-protonated amino groups and the excited chromophore which results in ...
