Carbon Dioxide Mitigation

This paper primarily presents on carbon dioxide mitigation by marine microalgae. Among the potential marine microalgae,Nannochloropsis oculatahas been identified as a promising species which can be utilized to reduce carbon dioxide concentration via photosynthesis process. The growth ofN. oculataand lipid synthesis for biodiesel production is influenced by various aspects. The aspects that are focused in this paper include light source and intensity, temperature, carbon dioxide concentration, and photobioreactor design. Besides, emerging technologies that are able to increase the efficiency of carbon dioxide reduction were also highlighted. As a whole,N. oculatamight play a key role in reducing the global carbon dioxide emission as well as enhancing the biodiesel production.

<div> <div> <div> <p>Nowadays, the search of efficient methods able to reduce the high atmospheric carbon dioxide concentration has turned into a very dynamic research area. Several environmental problems have been closely associated with the high atmospheric level of this greenhouse gas. Here, a novel system based on the use of surface-functionalized silicon quantum dots (sf -SiQDs) is theoretically proposed as a versatile device to bind carbon dioxide. Within this approach, carbon dioxide trapping is modulated by a photoinduced charge redistribution between the capping molecule and the silicon quantum dots (SiQDs). Chemical and electronic properties of the proposed SiQDs have been studied with Density Functional Theory (DFT) and Density Functional Tight-Binding (DFTB) approach along with a Time-Dependent model based on the DFTB (TD-DFTB) framework. To the best of our knowledge, this is the first report that proposes and explores the potential application of a versatile and friendly device based on the use of sf -SiQDs for photochemically activated carbon dioxide fixation. </p> </div> </div> </div>
