The dopant consist of nanoparticles of graphite, CuO, and ZnO, each of them added separately to co-oil in 1 wt% and 2 wt%. The data of pure co-oil are taken as the comparison. Analysis of the data reveals the values of solid and liquid specific heats and the heat of fusion related to phase transition of co-oil+dopant. In general, we found that the solid specific heat tends to decrease with dopant concentration, while liquid specific heat tends to increase with dopant concentration with a rather small variation for all type of dopant. The heat of fusion, on the other hand, decreases with the increase of dopant concentration. The temperature dependent enthalpy shows that the solid-liquid phase transition of co-oil occurred with a temperature change, which might be due to its mixture composition.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Coconut oil,Heat of fusion,Liquid-solid phase transition,Solid-liquid phase transitions,Solidification process,T-history method,Temperature dependent,Thermo-physical parameters[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]chemical dopant,coconut oil (co-oil),heat of fusion,Phase Change Material (PCM),solid and liquid specific heats,T-history method,temperature dependent enthalpy[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1204/1/012055[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
