Semi-Closed Oxy–Fuel Combustion Power Cycles with CO2 Recirculation
With the increases in organic fuel prices and growing legislative restrictions aimed at increasing environmental safety and reducing the carbon footprint, the task of increasing thermal power plant efficiency is becoming more and more topical. Transforming combusting fuel thermal energy into electric power more efficiently will allow the reduction of the fuel cost fraction in the cost structure and decrease harmful emissions, especially greenhouse gases, as less fuel will be consumed. There are traditional ways of improving thermal power plant energy efficiency: increasing turbine inlet temperature and utilizing exhaust heat. An alternative way to improve energy efficiency is the use of supercritical CO2 power cycles, which have a number of advantages over traditional ones due to carbon dioxide’s thermophysical properties. In particular, the use of carbon dioxide allows increasing efficiency by reducing compression and friction losses in the wheel spaces of the turbines; in addition, it is known that CO2 turbomachinery has smaller dimensions compared to traditional steam and gas turbines of similar capacity.

Lattice Boltzmann Method: Nuclear Reactor
Nuclear engineering requires computationally efficient methods to simulate different components and systems of plants. The Lattice Boltzmann Method (LBM), a numerical method with a mesoscopic approach to Computational Fluid Dynamic (CFD) derived from the Boltzmann equation and the Maxwell–Boltzmann distribution, can be an adequate option.

Photolyase Current Applications
The photolyase family consists of flavoproteins with enzyme activity able to repair ultraviolet light radiation damage by photoreactivation. DNA damage by the formation of a cyclobutane pyrimidine dimer (CPD) and a pyrimidine-pyrimidone (6-4) photoproduct can lead to multiple affections such as cellular apoptosis and mutagenesis that can evolve into skin cancer. The development of integrated applications to prevent the negative effects of prolonged sunlight exposure, usually during outdoor activities, is imperative.

Integrated Treatment of Agro-industrial Waste
This document reports a synthetic description of a research work in which a new integrated treatment was defined for the production of biofuel and the recovery of phosphorus compounds from agro-industrial residues. As the first step of the proposed process, anaerobic co-digestion was carried out to produce biogas by exploiting raw waste mixtures. Afterwards, the residual digestates were converted to syngas using supercritical wet gasification (SCWG. Finally, the liquid phases from SCWG were treated to recover the phosphorus content as MgKPO4×6H2O crystals. This integrated treatment could be a suitable approach to exploit agro-wastes because it can produce biofuel and valuable chemicals and generates a residual effluent with a very low polluting load
