An Insight Analysis of Nano sized Powder of Jackfruit Seed

Abstract

The preparation of biodegradable nanomaterials by blending starch nanocrystals with various polymer matrices are the most active research. This work reports aspect related to nano-sized particles of jackfruit seed. This approach is simple, faster, eco-friendly, cost effective and suitable for large scale production. X-Ray Diffraction studies analyze particles size, morphology, type of starch and degree of crystallinity. The particle size is found to be 12nm, specific surface area is 625 m 2 g -1 , contains A-type starch and 32% degree of crystallinity. A morphology index (MI) is developed from FWHM of XRD data to understand interrelationship of particle size and specific surface area. MI range is from 0.50 to 0.74. It is correlated with the particle size and specific surface area. It is observed that MI has direct relationship with particle size and an inverse relationship with specific surface area. __________________________________________________________________________________________

Thermal, Structural, and Physical Properties of Freeze Dried Tropical Fruit Powder

“…The X-ray diffraction patterns of papaya, guava, and sapota are shown in Figure 6, respectively. The diffraction peaks observed in the graph are broad, which indicate that the crystallite size is small which was similar to the results obtained by Theivasanthi and Alagar [14]. The particle size of each fruit powder has been determined using Debye-Scherrer formula:…”

“…Theivasanthi and Alagar [14] studied the XRD of Jackfruit Seed and reported diffraction peaks at around 15…”

Konjac Biomolecules Assisted–Rod/Spherical Shaped Lead Nano Powder Synthesized by Electrolytic Process and Its Characterization Studies

“…The specific surface area of lead nanopowder (which is important to many of the above mentioned industries) is dependent on the interrelationship of particle morphology and size. Morphology Index (MI) is calculated from FWHM of XRD data, based on our earlier report [31]. Sample lead nanopowder, (MI) range is from 0.50 to 0.75.…”

Chemical Precipitation Synthesis of Fe, Ni, and Co Doped Zinc Sulphide Nanoparticles

“…(4.6) Some emission peaks are observed in photoluminescence spectrum. [10,11]A strong peak of FeCl 3 doped ZnS (FZ-1) at 426nm, near the band edge due to free excition emission is observed in photoluminescence spectrum. [16][17][18][19] The broad band in the region of 400-800 nm, in photoluminescence spectrum of FeCl 3 doped ZnS is related to the amount of non-stochio-chiometric intrinsic defects and the same may be due to pure Fe doped ZnS as reported.…”
