1. An Overview of the Photocatalytic H2 Evolution by Semiconductor-Based Materials for Nonspecialists
The solar-to-chemical energy conversion is promising to tackle sustainability challenges toward a global future. The production of H2 from sunlight represents an attractive alternative to the use of carboniferous fossil fuels to meet our energy demands. In this context, the water splitting reaction photocatalyzed by semiconductors that can be excited under v

2. Sugarcane inoculated with endophytic diazotrophic bacteria: effects on yield, biological nitrogen fixation and industrial characteristics
Abstract: The growing need for the use of clean energy has led society to seek alternatives to fossil fuels in order to less pollute the environment. Sugarcane has been known to produce enough biomass and to have associative microorganisms, such as plant growth-promoting bacteria (PGPB), which have the potential to improve the yield of crops. The objective

3. Análise do processo de dessalinização solar com ênfase no método de umidificação e desumidificação
RESUMO A falta de água é um problema que afeta muitas regiões do nosso planeta, especialmente ilhas e locais de clima muito seco. Especialistas dizem que essa situação irá se agravar e que, em 2025, cerca de 1,8 bilhão de pessoas sofrerão com essa escassez. Embora métodos tradicionais de dessalinização sejam alternativas bem conhecidas e implantad

4. Economic and Environmental Analysis of Pellets’ Production in Rio Pardo Watershed, Brazil
ABSTRACT Economic and environmental aspects of residues energetic use in Brazil are extremelly important. In one hand, the country is today a recognized bioenergy producer in a global scenario; on the other, it is still struggling to provide a reliable renewable energy supply to rural communities. Local demand could be supplied through small investments usin

5. NI-MO SUPPORTED NANOPOROUS GRAPHENE AS A NOVEL CATALYST FOR HDS AND HDN OF HEAVY NAPHTHA
ABSTRACT Reducing sulfur and nitrogen compounds is essential in producing clean fuels for providing a green environment. In this regard, a novel nanocatalyst has been proposed for Hydrodesulfurization (HDS) and Hydrodenitrogenation (HDN) of heavy naphtha. To this end, Ni-Mo was loaded on nanoporous graphene (Ni-Mo/NG) through the incipient wetness impregnati

7. CÉLULAS SOLARES DE PEROVSKITAS: UMA NOVA TECNOLOGIA EMERGENTE
Solar energy has been considered as an important source of clean and safe energy to overcome the problems associate to the burn of fossil fuels (e.g. climate changes, pollution, health problems, etc.). In the area of photovoltaics, devices that convert solar energy into electricity, perovskites solar cells (PSC) have attracted great attention due to their ra

9. Agricultura familiar e expansão da cana-de-açúcar sobre áreas de culturas anuais no Estado de Goiás a partir da safra 2005/06 / Family farming and sugarcane expansion over areas of annual crops in Goiás State from the 2005/06 harvesting season
Sugarcane ethanol, considered a major source of clean energy, is an option for changing the energy matrix of Brazil and also the world, contributing to the reduction in consumption of fossil fuels. In Brazil, Goiás State is one of the sugarcane expansion s frontiers to meet the growing demand for biofuels. But this expansion means sugarcane mills could take

10. Refinery production planning and scheduling: the refining core business
Intelligent production planning and scheduling are of paramount importance to ensure refinery profitability, logistic reliability and safety at the local and corporate levels. In Brazil, such activities play a particularly critical role, since the Brazilian downstream model is moving towards a demand-driven model rather than a supply-driven one. Moreover, ne
