life (Figure 4鈥 1): (O 2 ) supports respiratory metabolism; CO 2 is the source of carbon for photosynthesis; N 2 is an essential element of proteins; S is essential for protein and vitamin synthesis; and P is incorporated into many organic molecules and essential for metabolic energy use...
hydrosphere, and lithosphere (Schlessinger 1997). The main processes can be understood as the biosphere’s storage or release of energy by uptaking or liberating molecular species with essential components

The main biogeochemical cycles involve different molecular species whose composition provides the essential elements for both building polymeric structures and the biochemical transduction of energy in cells, like C, N, S, P, and O. The biogeochemical cycles are activated when the biosphere couples to...

Each layer receives different influences from the energy sources available, but interrelate as a whole, to form weather patterns experienced on the surface. When it comes to level 2 energies, the most variable are solar UV outputs, which have large potential to alter climate cycles. Solar UV ...
In Japan, a deep relationship with nature and a refined aesthetic sensibility are seen as essential components for engaging with these cycles. The Pavilion invites reflection on what can be discovered within the endless cycle of life, where there is no clear beginni...
These opposing reactions function as a mutually regulating system that enables better metabolic regulation and fine-tuned utilization of energy and biomolecules (Figures 1A and 1B). Such systems ensure the availability of essential substrates even if they are not available from external sources, thus ...
The elements of carbon, hydrogen and oxygen, and the basic nutrient elements nitrogen, phosphorus and sulphur, are essential for life on earth. The term ‘global biogeochemical cycles’ is used for describing the transport and transformation of these substances in the global environment. In recent ...
(e.g. naphthalene, indole, pyridine, quinoline, etc.), due to its inherent stability owing to the aromaticity, harsher reaction conditions are often needed for the dearomatization of benzene ring, especially the dearomative cycloadditions. Photocatalysis is the most typical strategy for the ...
