“…These products are similar to petroleum fuels, such as gasoline and diesel, and are therefore, considered to be fully compatible with the automotive industry. 14 For Rodionova et al 15 biofuels are energy-enriched chemical products, generated through thermochemical or biochemical processes or derived from the biomass of living organisms by complex reactions. They can be classified into two categories: primary and secondary biofuels.…”

The characterization of the physical-chemical properties and the thermal behavior of oilseed fruits for biofuels production has gained interest in the scientific community and society more generally, in particular with regard to their use as partial replacements for fossil fuels and for the possible reduction of air pollutants that cause problems for human health, animals, and plants. These oilseed fruits, which are rich in lipids, triglycerides, fatty acids, carotenoids, and other greasy compounds, can be transformed into solid, liquid, and gaseous products by different thermochemical conversion processes (conventional combustion, pyrolysis, oxy-fuel combustion, gasification and transesterification). This review investigates the different oleaginous feedstocks commonly found in the forests and plantations of Brazil -for example, olive stones, palm fruits, babassu coconut, macauba fruits, tucumã seeds and soybeans, and the respective residues generated from biofuel production and manufacturing processes. The main opportunities and challenges associated with the use of biofuels produced from these oilseed fruits lie in the fact that internal combustion engines using fossil fuels do not need to undergo modifications and mechanical adaptations to operate, and there is no corrosion risk and / or deterioration of metallic parts. Biofuels produce less greenhouse gas, or their pollution is considered neutral. Finally, the native forests of Brazil and the world present a vast number of different oleaginous species that still need be studied because they have excellent potential to be used as biofuels, as they are renewable energy sources and are sustainably eco-friendly.

Influence of osmolytes on the stability of thylakoid‐based dye‐sensitized solar cells

et al. 2019

Summary In recent years, there has been considerable interest in incorporating naturally occurring components of the photosynthetic apparatus into man‐made solar cells, because of the high quantum efficiency of photosynthetic reaction centers. One hurdle to overcome regarding the use of native membranes in these devices is their limited lifespans. In this study, we used stabilizers to increase the long‐term viability of biomolecules in vitro, thereby alleviating this challenge. In this regard, it is known that osmolytes, such as glycine betaine (GB) and sucrose, preserve photosynthetic activity in isolated photosystems. Upon investigation of the thermal protection properties of GB and sucrose in thylakoid‐based dye‐sensitized solar cells, we report that the addition of GB and sucrose to the thylakoid photosensitizer maintains nonzero photocurrent in the thylakoid‐based solar cell upon heating to 50°C. At 50°C, the GB‐containing cell displayed about a fourfold increase in photocurrent than the control cell, in which the photocurrent was decreased to nearly zero. The addition of 0.5M and 1M sucrose has respectively caused nearly 40% and 70% increases in photoinduced electron transfer activity over the control at 35°С. Similarly, though to a lesser extent, 1M GB caused an approximate 40% increase in electron transfer activity as well. Moving forward, this approach will be extended to alternative membrane protein isolation strategies, allowing for an accurate comparison with traditional detergent‐isolated complexes, with the ultimate goal of developing a cost‐effective and sustainable solar cell.

Advances in Nanocatalyst Design for Biofuel Production

The exploitation of nanocatalysts, at the boundary between homogeneous and heterogeneous catalysis, offers new efficient ways to produce renewable biofuels in environmentally friendly conditions. Specifically, biodiesel and high density fuels have been chosen as major topics of research for the design of catalytic nanomaterials. As solid‐state catalysts, they are recyclable, and their nanometric particle size enables high activities that approach those of homogeneous catalysts. In addition, they offer novel and unique catalytic behaviors not accessible to solids above the nanometer range. Furthermore, the use of magnetically active materials has led to the development of nanocatalysts easily recoverable through the application of magnetic fields. In this Minireview, the latest achievements in the production of advanced biofuels using stable, highly active, cheap and reusable nanocatalysts are described.
