A comprehensive study of the upcycling of litchi chinensis waste into a sustainable transesterification catalyst.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Biodiesel has gained popularity in the past decade and now serves in the forefront as a renewable fuel substitute to fossil fuel in the transportation sector. The current investigation aims at producing a low-cost transesterification catalyst from litchi residue, generated as a waste from the food processing industries. The catalyst was utilized for biodiesel formation from jatropha curcas oil. Advanced analytical tools were used to thoroughly characterize both the catalyst and the final product. The catalyst characterization results established the presence of Ca and K as active metal components. Utilizing one-factor-at-a-time approach, the influence of reaction parameters on the catalytic transesterification process was rigorously investigated. An impressive biodiesel yield of 99.4% along with a fatty acid methyl ester (FAME) conversion rate of 99.5% was attained under optimal reaction conditions characterized by a methanol to oil ratio of 1:7.5, a catalyst loading of 5 wt%, a reaction duration of 150 min, and a temperature of 65 °C. Furthermore, the kinetics and thermodynamics of the reaction was evaluated and the activation energy of the process was calculated to be 37.01 KJmol
