Definition of Biogas Biogas is a renewable energy source generated through the anaerobic digestion of organic materials by microorganisms in the absence of oxygen. This process transforms biodegradable waste into a combustible gas mixture primarily composed of methane (CH4) and carbon dioxide (CO2). Biogas production not only offers an effective waste management solution but also […]
Definition of Topological Semimetals Topological semimetals are an intriguing class of materials situated at the intersection of condensed matter physics, quantum mechanics, and materials science. Unlike conventional semiconductors, these materials exhibit partially filled conduction and valence bands, allowing electrons to move between them with minimal energy input. The incorporation of topological principles reveals that certain […]
