The objective of this study was the evaluation of the production of base oils for lubricants of biological origin using vegetable and used frying oils as feedstock.The production method was based on a two-stage transesterification process.Initially, fatty acid methyl esters were obtained via methanolysis (first stage), click here and they were used
Summary: Hybrid lead halide ABX3 perovskite solar cells (PSCs) have emerged as a strong competitor to the traditional solar cells with a certified power conversion efficiency beyond 25% and other remarkable features such as light weight, solution processability, and low manufacturing cost.Further development on the seattle seahawks socks efficiency
In the light of ongoing land use changes, it is important to understand how multitrophic communities perform at different land use intensities.The paradox of enrichment predicts that fertilization leads to destabilization and extinction here of predator-prey systems.We tested this prediction for a land use intensity gradient from natural to highly
