Hydrogen-assisted nannochloropsis sp. microalgae biodiesel to operate cleaner diesel engines.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The need to find sustainable energy sources has taken the center stage in the light of the growing energy global requirements. The renewable energy sources have also taken much interest in biofuels, as they promise to add renewable and environmentally benign sources of energy. The feedstock used in biodiesel is usually a wide range of inexpensive feedstock. In the current research, a new synthesis method using a feedstock with a green microalga, namely, Nannochloropsis sp. is defined. According to the authors, bio-diesel blends based on this microalgal source would help in producing less toxic fuels, increase the functionality, and at the same time, minimize emissions. The present paper examines production of biodiesel using Nannochloropsis sp. a microalga with high calorific value thus qualifying as a feedstock. After one hour of ultrasonication at 500 Hz frequency, the recovery of bio-oil was around 720 mL. Afterwards, the resulting bio-oil was undergone to a single-pot transesterification with sodium hydroxide as the catalyst in methanol to extract the bio-oil with an extraction efficiency of 92%. Nuclear magnetic resonance spectroscopy, gas chromatography-mass spectrometry, and Fourier-transform infrared spectroscopy were used to determine physicochemical properties of the resultant biodiesel ensuring it was suitable as a fuel. The combustion stability of the resulting B20 + 7.5H
