Thermodynamic and kinetic modeling of the protection of mammalian cells against ethanol‐induced damage by extracts of Jatropha curcas (Euphorbiaceae)

Engineering Reports, Volume 1, Issue 5, December 2019., 2019
Jatropha curcas extracts protect mammalian cells against damage by ethanol. A thermodynamic modeling of protection based on extract concentrations is presented. Optimization of protection could be done using the proposed model. The medicinal plant Jatropha curcas exerts beneficial effects against ethanol toxicity in humans.

Non‐Hydrothermal Synthesis of MCM‐41‐Type Catalysts Modified With Zirconia and Tungsten Oxide for the Esterification of Levulinic Acid With Ethanol

ChemistrySelect, Volume 11, Issue 8, 25 February 2026.
Ordered mesoporous silica MCM‐41, synthesized through a simple and rapid non‐hydrothermal method, was functionalized with ZrO2 and WO3 for catalytic application in the esterification of levulinic acid with ethanol. The incorporation of these oxides yielded active and stable acidic heterogeneous catalysts that maintained their catalytic activity for 180

About the Influence of Doping Approach on the Alkali Metal Catalyzed Slow Pyrolysis of Xylan

Journal of Chemistry, Volume 2019, Issue 1, 2019., 2019
In this study, we highlighted how the catalytic effect of alkali metals on xylan pyrolysis is strongly affected by the adopted doping approach. Thermogravimetric and pyrolysis tests, up to 973 K and at a heating rate of 7 K/min, were conducted on a set of potassium‐ or sodium‐doped xylan samples containing controlled amounts of KCl or NaCl introduced ...

Assessing Renewable Energy Supply for Brazilian Ethanol‐to‐Jet Plants

SCI Sustainability, Volume 2, Issue 1, January 2026.
ABSTRACT Ethanol is the leading global biofuel, but it faces the challenge of diversifying its use into hard‐to‐electrify sectors such as aviation. The Ethanol‐to‐Jet (EtJ) process, which converts ethanol into hydrocarbons for sustainable aviation fuels (SAF), is forecast to be a key SAF pathway for scaling up soon.

Syngas obtained by microwave pyrolysis of household wastes as feedstock for polyhydroxyalkanoate production in Rhodospirillum rubrum

Microbial Biotechnology, Volume 10, Issue 6, Page 1412-1417, November 2017., 2017
The effects of using syngas obtained by microwave pyrolysis of municipal wastes as feedstock on the physiology and PHB production of Rhodospirillum rubrum were investigated demonstrating the robustness of this bacterium as biocatalyst. Summary The massive production of urban and agricultural wastes has promoted a clear need for alternative processes of

Impacts of the Recent Expansion of the Sugarcane Sector on Municipal per Capita Income in São Paulo State

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
The aim of this study is to evaluate the impacts of this expansion on the income of people in the state’s districts and towns. Beginning with a breakdown of the main determinants of per capita income, a spatial dynamic panel model is proposed. The proportion of adults in the municipal population, the labour force utilization rate, and the average ...

Social Awareness as a Catalyst for Biochar Adoption in the Agricultural and Forestry Sectors

GCB Bioenergy, Volume 17, Issue 10, October 2025.
Review on the state‐of‐the‐art in the topic of social awareness for biochar application in the agricultural and forestry sectors. We individuated the main barriers to biochar adoption and defined the possible steps to foster its application. ABSTRACT Biochar, a carbon‐rich material produced from the pyrolysis of organic matter, has garnered attention ...
