成果简介	NOVELTY - Enhancement in thermal conductivity of bio-nanofluids involve synthesising carbon nanospheres from biomass-based precursors, where biomass-based precursor is obtained from the eight different wastes namely Samanea saman, C.allerya atropurpurea, Magnolia champaca seed pods, Acacia auriculiformis, oil palm leaves, Caesalpinia Sapan, onion peel, and arecanut and these precursors labelled as SI to S8. The procedure for synthesizing carbon nanospheres from precursors SI to S8 involves removing the biomass or biowaste material from the plant, washing, and then drying in the sun to remove moisture and create a dried substance. The material is ground and passed through a vibratory sieve shaker equipped with a 35-250 pm mesh to obtain a fine powder. The obtained powder undergoes pyrolysis in a quartz tube furnace with a continuous nitrogen gas flow at approximately 700-900℃, resulting in a carbon residue. USE - Method for enhancement in thermal conductivity of bio-nanofluids. ADVANTAGE - The method exhibits negative zeta potential values ranging from -45.6-(-17.0) milliVolt for the samples SI to S8, respectively, signifying stability, crucial for enhancing the thermal conductivity of nanofluids and excellent viscosity characteristics with low pumping power requirements, enhances thermal conductivity and stability of nanofluids using biomass-derived carbon nanospheres and heat transfer efficiency by increasing the effective surface area for thermal interactions. DETAILED DESCRIPTION - Enhancement in thermal conductivity of bio-nanofluids involve synthesising carbon nanospheres from biomass-based precursors, where biomass-based precursor is obtained from the eight different wastes namely Samanea saman, C.allerya atropurpurea, Magnolia champaca seed pods, Acacia auriculiformis, oil palm leaves, Caesalpinia Sapan, onion peel, and arecanut and these precursors labelled as SI to S8. The procedure for synthesizing carbon nanospheres from precursors SI to S8 involves removing the biomass or biowaste material from the plant, washing, and then drying in the sun to remove moisture and create a dried substance. The material is ground and passed through a vibratory sieve shaker equipped with a 35-250 pm mesh to obtain a fine powder. The obtained powder undergoes pyrolysis in a quartz tube furnace with a continuous nitrogen gas flow at approximately 700-900℃, resulting in a carbon residue. The carbon residue is then washed with a 0.1 Molar hydrochloric acid solution and neutralised using distilled water. The material is dried at 50-100℃, formed spherical carbon nanoparticles. The otained spherical carbon nanoparticles are then used to prepare a product.
