Remarkable effect of l-Ascorbic acid on crystal morphology, structural, crystalline perfection, optical, photoluminescence and dielectric properties of Zinc(tris) thiourea sulphate (ZTS) single crystals

Large size growth of Zinc(tris) thiourea sulphate (ZTS) crystals has been successfully done through slow solvent evaporation technique in presence of l-Ascorbic acid (LAA).The possibility of any extra phase due to presence of LAA was ruled out through structural analysis.The deviation in lattice parameters and shift ecoflow cheap in peaks position

Free radical exposure creates paler carotenoid-based ornaments: a possible interaction in the expression of black and red traits.

Oxidative stress could be a key selective force shaping the expression of colored traits produced by the primary animal pigments in integuments: carotenoids and melanins.However, the impact of oxidative stress on melanic ornaments has only recently been explored, whereas its role in the expression of carotenoid-based traits is not fully understood.
