Bio-Stiumlants Extend Shelf Life and Maintain Quality of Okra Pods
Abstract Abstract Okra (Abelmoschus esculentus L.), a tropical annual crop, is a highly perishable vegetable. Okra pods deteriorate rapidly after harvesting. The pods undergo physical and physiological changes that diminish storability and quality. The purpose of this study was to investigate the effect of bio-stimulants on the storability and quality of okra pods stored at 4 °C and 25 °C ... Read more

Effects of Thickness and Ag Layer Addition on the Properties of ZnS Thin Films
Zinc sulfide (ZnS) thin films, with different thicknesses and different silver (Ag) middle layer thickness, were prepared on glass substrates using thermal evaporation. The structural and optical properties of ZnS thin films were characterized by X-ray diffraction and UV-VIS-NIR spectrophotometer. The X-ray diffraction analyses indicated that ZnS films have cubic structure with (111) preferential orientation, whereas the diffraction patterns sharpen ... Read more
