【题目】DMetal-organicframeworks (MOFs) are compounds(化合物)that are set to solve some tough challenges:producingwater in the desert, removing greenhouse gases from the air andstoring dangerousgases more safely.T heArizona desert is really dry. Anyone stuckin it without water woulddie from ...
Compounds and molecules are built from elements composed of at least two atoms joined with a chemical bond. Learn how elemental personalities build...
For one thing, they are complex and giant molecules and are different from low molecular weight compounds like, say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thousand thousands. These...
. Bromine, like its neighbours chlorine and iodine in the periodic ( = of period ) table, has molecules made up of two atoms each. In these liquid elements, the molecules are close together, but not so crowded;they can pass lightly by one another.1.All elements are made up of ....

aArylboron compounds are invaluable reagents in synthetic organic chemistry1 for constructing diverse functional molecules via Suzuki–Miyaura coupling,2 Petasis reaction,3 etc. While a variety of arylboron compounds can be prepared by a reaction of aryl Grignard reagents (or aryllithiums) wi 正在翻译...
【解题思路】根据画线短语前的"These crysalline(结晶的)groups ofmetals.. can be made into materials with an extremely high absorptionabilty, atracting specific molecules to their surfaces"可知,这些由有机分子连接在一起的金属结品群可被制成吸收能力极高的材料,以吸引特定分子到它们的表面,即金属有机...
Of the three domains of living things, which have prokaryotic cells, and which have eukaryotic cells? What are the minimum required structures for all cells? Draw and label a cell membrane. What type of molecule is most of this membrane made o...
Compounds accumulating in the media would therefore originate from the myotubes. Lipidomic profiling confirmed that the conditioned media was exogenous palmitate-free (Supplementary Fig. 1b). This conditioned media was transferred to naive differentiated C2C12 myotubes (Fig. 1a). Conditioned media from ...
