Effect of graphene nanoparticles on engine operated using simarouba

open access: yesJournal of Mines, Metals and Fuels, 2022
In the present study, simarouba biodiesel suspended with graphene nano particles was prepared. Prepared combination is mixed with diesel to form test samples. Ultraviolet–visible (UV-V) spectrometry was used for characterizing the dispersion. Tests were carried out on a single-cylinder, water-cooled and computerized 4-stroke diesel engine.

Physiological and Growth Responses of Tropical Dry Forest Tree Seedlings to Water and Nutrient Additions: Comparisons Between Nitrogen Fixers and Non‐Fixers

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
This study examined the physiological and growth responses of tropical dry forest tree seedlings to water and nutrient additions, comparing nitrogen (N)‐fixing and non‐fixing species. The results showed that N‐fixing species responded more strongly to nutrient addition, accumulating significantly more biomass and increasing height growth rate. Overall,
