Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Life cycle assessment of biodiesel synthesis from waste cooking oil using bifunctional heterogeneous catalyst

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...

Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.

Bridging the Gap: Student Voices on Recruitment and Retention in Ecology

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Students entering ecology and environmental science face a variety of challenges, including limited awareness of career paths, lack of mentorship, and difficulties connecting with peers and faculty. These challenges are often amplified for students from marginalized backgrounds, who may also encounter microaggressions, underrepresentation, and
