Could silicon be a plausible substitute for carbon in alien biochemistry?5 answersSilicon-based life is not a plausible option in any environment, including water-rich environments, due to the limited chemical capacity of silicon and the formation of ubiquitous silica. While there have been speculations about the possibility of silicon-based life in scientific works and science fiction, the physical and chemical properties of carbon and silicon, as well as their compounds, have been compared, showing mutual dependence of carbon and silicon circulations. The idea of extraterrestrial life based on silicon has intrigued scientists, but on Earth, carbon is the main building block of life. The uniqueness of life on our planet is attributed to the structure and mechanisms of carbon-based biomolecules, and the existence of silicon-based compounds is still a widely discussed hypothesis. Alternate biochemistries based on elements other than carbon, such as silicon and germanium, have been considered, but the underlying biochemistry on Earth is primarily carbon-based.

What weak base to react with silicon?3 answersSilicon can react with weak bases such as alkoxide bases and Lewis bases. Alkoxide bases have been used in high temperature heterogeneous reactions to prepare mono- and dialkoxysilanes with good yields. On the other hand, Lewis bases like 2,2’-bipyridine (bpy) and 1,10-phenanthroline (phen) have been used to form Lewis base adducts of Si(N3)4, which are thermally stable and can be handled safely. These Lewis base adducts can be synthesized by treating the disodium salt of hexaazidosilicate with the respective Lewis bases. Therefore, both alkoxide bases and Lewis bases can be used to react with silicon, depending on the specific reaction and desired product.

Does the silicon granulometry affect the hydrogen production?5 answersThe granulometry of silicon does affect the production of hydrogen. The porosity of silicon plays a role in determining the volume of hydrogen released when silicon interacts with water. An increase in silicon porosity leads to a reduction in the total volume of hydrogen produced. However, the use of silicon fine particles, formed by pulverizing silicon chips or grinding debris, can still generate hydrogen in practical amounts. Additionally, the reaction of generating hydrogen from silicon powder and an aqueous solution can be used to produce hydrogen, and the by-products of this reaction can be utilized in other applications. Therefore, the granulometry of silicon, whether in the form of fine particles or porous silicon, can impact the efficiency and volume of hydrogen production.

Does the reaction of Si with water in acidic media generate hydrogen?5 answersThe reaction of Si with water in acidic media does not generate hydrogen. Si sludge, which is generated through the manufacturing process of Si wafer, was found to contain impurities such as Al compounds that hindered hydrogen generation. However, Si nanopowder, fabricated by the bead milling method, reacts with water to generate hydrogen even in neutral pH regions. The reaction rate for hydrogen generation greatly increases with pH, indicating that hydroxide ions are the reacting species. Si nanopowder easily reacts with water to generate hydrogen, and the hydrogen generation rate strongly depends on the pH value of the solution. Si-based agents, consisting of crystalline Si, can generate a high amount of hydrogen by reacting with weak alkaline solutions. In summary, Si can generate hydrogen when reacting with water in neutral or weak alkaline pH regions, but not in acidic media.
