Fluorescence Imaging has been developed as a nondestructive method for assessing fruit and vegetable qualities and attributes. There are many attributes can be accessed using a laser based fluorescence imaging such as chlorophyll content and other pigments responsible for fruit colors and ripeness. The assessment of these attributed depends on the wavelength of excitation lasers used. This rese…
Activated carbon were prepared from shell of Terminalia cattapa. The shell of Terminalia cattapa were carbonized by conventional carbonization for 3 hours. The ratio of mass percentase of carbon granular : KOH is 2 : 1. The mixtures of carbon granular and KOH were soaked in 200 mL boilong water for 12 hours, 24 hours and 36 hours. Respectivaly and subseguent by irradiated with output power of 6…
