Carbon nanotubes (CNT) are produced from a rare variety of natural vein graphite (VG) distinctive to Sri Lanka using electric arc discharge. Electric arc-discharge produces both single walled and multi walled nanotubes. The products are characterized using high resolution electron microscopy and Raman spectroscopy for verification and validation.Keywords

The deficiency of nutrients during the early plant growth stages diminishes plant development, leading ultimately to lower crop yields. In this context, nanotechnology has been used to develop advanced seed coatings with sustainable and precise release properties to deliver supplements to the plant effectively. Zinc-doped hydroxyapatite–urea nanoparticles were synthesized and incorporated into a seed coating. This system enhanced plant growth, yield and root–shoot nutrient content in Zea mays seeds. The nanohybrid is futuristic as a macro– micro plant nutrient delivery agent and opens up new opportunities to explore the suitability of metal-doped hydroxyapatite nanoparticles in agriculture.Keywords
