Sustainable hydrothermal synthesis of carbon dots from cyanobacterial and microalgal biomass residues

Maria Teresa Araujo Pinheiro, Emerson Andrade Sales, Claude Yéprémian, Nguyêt-Thanh Ha Duong et autres

We report a sustainable and straightforward hydrothermal synthesis of carbon dots (CDs) derived from biomass residues of the microalga Chlorella vulgaris and the cyanobacterium Leptolyngbya boryana . Three feedstocks were investigated: C. vulgaris post-lipid extraction (CVR), untreated L. boryana biomass (LBB), and …

Separability and harmony in ecumenical systems

Sonia Marin, Luiz Carlos Pereira, Elaine Pimentel, Emerson Andrade Sales

Abstract The quest of smoothly combining logics so that connectives from different logics can co-exist in peace has been a fascinating topic of research. In 2015, Dag Prawitz introduced a natural deduction system for an ecumenical first-order logic, unifying classical and intuitionistic …

Fast Micro-Pyrolysis of Myristic Acid in the Presence of Fresh and Equilibrium FCC-Type Catalysts

Noyala Fonseca, Alan Silva dos Santos, Yiu Lau Lam, R. Fréty et autres

The production of truly sustainable biofuels involves many challenges, from the choice of raw materials to the rational use of reagents and catalysts. In the present study, the catalytic fast micro-pyrolysis of a model fatty molecule myristic acid was performed over fresh …

Basicity-tuned graphitic carbon nitride supported MgO heterogeneous catalysts for efficient transesterification of groundnut oil to biodiesel

K. Vignesh, Donato Alexandre Gomes Aranda, Emerson Andrade Sales, B. M. Jaffar Ali

Quality and quantity of biodiesel derived from oil depend on the type of feedstock and the transesterification process. To maximize biodiesel production efficiency and ensure the desired fuel quality, it is crucial to develop and optimize feedstock-specific production processes. This study reports …
