Secondary chain motion and mechanical properties of γ-irradiated-regenerated cellulose films
(
Wiley-VCH Verlag
, 2017 , Article)
Regenerated cellulose films prepared using NaOH/urea solvent system were exposed to different doses of γ-radiation, ranging from 5 to 50 kGy to modify their properties. Change in relative crystallinity as a function of ...
Electrochemical performance of Ti3C2Tx MXene in aqueous media: towards ultrasensitive H2O2 sensing
(
Elsevier Ltd
, 2017 , Article)
An extensive characterization of pristine and oxidized Ti3C2Tx (T: O, OH, F) MXene showed that exposure of MXene to an anodic potential in the aqueous solution oxidizes the nanomaterial forming TiO2 layer or TiO2 domains ...
