Biomass transfer efficiency
WebAchieving high mechanical performances in nanocomposites reinforced with lamellar fillers has been a great challenge in the last decade. Many efforts have been made to fabricate synthetic materials whose properties resemble those of the reinforcement. To achieve this, special architectures have been considered mimicking existing materials, such as nacre. … WebCalculating efficiency of biomass transfers The efficiency of biomass transfer is a measure of the proportion of biomass transferred from a lower trophic level to a higher one.
