Zinc (Zn) doped hematite (α-Fe2O3) nanoparticles with varying concentrations (pure, 2%, 4% and 6%) were synthesized via sol-gel method. The influence of divalent Zn ions on structural, optical dielectric behavior studied. X-ray diffraction (XRD) pattern samples indexed to rhombohedral R3c space group 14–21 nm crystallite size. lattice parameter (a c) values increase upto decrease afterwards. surface morphology prepared explored using transmission electron microscopy (TEM). band gap measured...

Rice is a major staple food across the world in which wide variations nutrient composition are reported. improvement programs need germplasm accessions with extreme values for any nutritional trait. Near infrared reflectance spectroscopy (NIRS) uses electromagnetic radiations NIR region to rapidly measure biochemical of and agricultural products. NIRS prediction models provide rapid assessment tool but their applicability limited by sample diversity, used developing them. spectral...
