8 ott 2024 · Reductive depolymerization typically involves external H 2 or hydrogen donor solvent (e.g., methanol, ethanol, and isopropanol) to convert lignin into aromatic hydrocarbons. However, this method faces challenges due to the high reaction temperature required and the necessity of external H 2 [27, 28].

5 giorni fa · Hidden biological processes can affect how the ocean stores carbon. Microscopic organisms in the ocean play a key role in removing carbon dioxide from the atmosphere. A new study unveils a hidden biological factor that could change our understanding of how this process works, and make climate change predictions more accurate.
22 set 2024 · Two science buildings adorn the Stanford University campus in Palo Alto; the best, 2003’s James H. Clark Center, wraps three low buildings around a grassy central court and floats a red metal canopy 4 feet above the trio.
(DOI: 10.1145/280811.281023) The Geometry Engine[1] is a special-purpose VLSI processor for computer graphics. It is a four-component vector, floating-point processor for accomplishing three basic operations in computer graphics: matrix transformations, clipping and mapping to output device coordinates.
