Experimental Investigation on Spirogyra Biodiesel With Di‐Tert‐Butyl Peroxide as a Cetane Booster
Energy Science &Engineering, Volume 13, Issue 6, Page 3328-3341, June 2025.Engine tested with third‐generation biodiesel. Cetane improver di‐tert‐butyl peroxide was added to improve combustion. The emissions analysis indicated a 53.8% CO decrease and a 9.1% NO rise to 24.9%. ABSTRACT This study investigates the impact of incorporating 30% spirogyra algae biodiesel (SBD30) with di‐tert butyl peroxide (DTBP) as a cetane booster

ChemistryOpen, Volume 14, Issue 5, May 2025.Aromatic hydrocarbons are widely used solvents in chemical processes. Due to concerns about toxicity to the environment and human health, the introduction of more sustainable alternative solvents is highly desirable. In this work, the use of dl‐limonene was explored to develop formulations containing carnauba wax as a release agent in the production of

Nano Select, Volume 6, Issue 3, March 2025.The SEM shows a non‐uniform distribution of grains, while XRD indicates unit cell expansion. Al3+ ions predominantly occupy the B‐site, whereas other ions are distributed in both the sites of the nano spinel ferrites. The coercivity is attributed to the overlapping of single and multiple magnetic domains. The highest dye degradation occurred 75 minutes

Autoignition flames transfer matrix modeling
, 2019 Modern gas turbines need to fulfill increasingly stringent pollutants emission targets. Ansaldo Energia GT26 and GT36 respond to this by means of the lean-premixed combustion technology and a sequential combustion system. In particular, the second combustion chamber relies on the autoignition principle for flame stabilization.
