Cotton is one of the most important raw materials for textile and clothing production.

Deep eutectic solvent mediated synthesis and fabrication of a WO3–MgO nanocomposite as an electrode material for energy storage applications

“…6a), confirming the presence of UV absorbing MgO nanoparticles. 27 The indirect band gap energies of WO 3 nanoparticles and WO 3 –MgO samples are obtained from the Tauc plot of F ( R ) vs . photon energy ( hν ), which is derived from the Kubelka–Munk function as follows 28 :where R denotes the reflectance values of the samples.…”

The optical bandgap energies could be determined from the tangent drawn to the curve obtained by plotting (F(R)hu) 1/2 vs. photonic energy (hu) (Fig.…”

Synthesis and Characterization of Polypyrrole-Protected Y2O3 Binary Composite: A Promising Electrode Material for Supercapacitors

“…Additionally, a nearly identical diffraction pattern showing a small deviation of peaks from Y 2 O 3 was seen for the PPy-Y 2 O 3 composite material, revealing the homogenous participation of both PPy and Y 2 O 3 phases in the nanocomposite. The optimal interaction between the various phases in the nanocomposite is demonstrated by a minor change in a few peak positions [33,34].…”
