Photons as Working Body for Photovoltaic Devices: Conversion of Photon to Electron from a Simplified Perspective

Advanced Theory and Simulations, Volume 9, Issue 1, January 2026.
In this work two models to study the photovoltaic response of solar cells are reported. The first model considers the bandgap effect to quantify the conversion of photons into electrons that makes up the photocurrent in the maximum electrical output power condition. The second model quantifies photocurrent in the short circuit condition from the energy

Neem oil (Azadirachta indica) as a promising feedstock for biolubricant production: enzymatic synthesis, process optimization, and molecular studies

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 237-252, January/February 2026.
Abstract The fuel industry remains closely tied to oil‐based fuels. This relationship is responsible for increasing greenhouse gas emissions. Biofuels are an alternative to petroleum‐based fuels that could make industrial production lines more sustainable.

A “crise dos refugiados” na Europa – entre totalidade e infinito

Comunicação e Sociedade, 2019
O eu e o outro. A totalidade e o infinito. Ou seja, a totalidade como o discurso do eu, que apaga o outro; e o infinito como o discurso do outro, que limita e impõe reservas ao discurso da totalidade. É numa relação face a face que eu encontro o outro, o

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1948-1969, November/December 2025.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Hydrogen production by Enterobacter cloacae via dark fermentation using an agroindustrial residue, cashew apple bagasse

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 4, Page 1207-1218, July/August 2025.
Abstract The use of biomass for the production of hydrogen gas (H2) offers a promising pathway toward sustainable energy systems. However, effective H2 production is still hindered by technological challenges, particularly in selecting appropriate feedstocks and optimizing production processes.

Enhancing Dietary Diversity and Nutritional Security Through Farm Production Diversity: Evidence From Rain‐Fed Regions in Southern Punjab, Pakistan

Food and Energy Security, Volume 14, Issue 3, May/June 2025.
ABSTRACT Farm production diversity is widely recognized as a critical factor in enhancing household dietary quality, yet limited empirical evidence exists on its role in addressing food and nutrition security among smallholder farmers in Pakistan, particularly in rain‐fed regions. These areas face unique challenges, including climate variability, water
