HKUST-1 (HKUST ⇒ Hong Kong University of Science and Technology), [1] which is also called MOF-199, [2] is a material in the class of metal-organic frameworks (MOFs). Metal-organic frameworks are crystalline materials, in which metals are linked by ligands (so-called linker molecules) to form repeating coordination motives extending in three ...
HKUST-1 is another early example of a divalent carboxylate MOF. [4] Reported around the same time as MOF-5, HKUST-1 is a copper ‘paddlewheel’ based MOF where two copper ions form a dimeric unit with four bridging carboxylates creating a square planar geometry around two adjacent copper sites. The two copper ions in the paddlewheel ...
As one might expect, given the greater Lewis acidity of Cr(III) vs. Cu(II), MIL-101 is much more active than HKUST-1 as a catalyst for the cyanosilylation of aldehydes. Additionally, the Kaskel group observed that the catalytic sites of MIL-101, in contrast to those of HKUST-1, are immune to unwanted reduction by benzaldehyde.
Sonochemical synthesis, which allows nucleation reactions to proceed rapidly through acoustic generation of localized heat and pressure, has been explored as a way to shorten synthesis times. [ 32 ] [ 33 ] As with the case of zeolites, microwave-assisted synthesis has also been of interest for the rapid synthesis of ZIFs.
Gallium nitride (Ga N) is a binary III/V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure.
MIL-53(Cr) was the first reported member of the MIL-53 family and is built up from Cr 3+ as metal center and terephthalate (benzene-1,4-dicarboxylate) as linker molecules. [1] Based on the toolbox-like design of metal-organic framework materials, different metal centers or linker molecules can be used for the synthesis of other members of the ...
Ant Anstead is reflecting on how far his relationship with his ex-wife, Christina Haack, has come, more than four years after they split.. While appearing as a guest judge on the Feb. 19 episode ...
The HKUST Learning Commons provides ~600 seats and has 5 zones: Group Study, Open Study, Refreshment, Teaching, and The Creative Media Zone. [9] The Library and its staff were very active in supporting the university in the University Grants Committee (Hong Kong)'s Hong Kong Research Assessment Exercise of 2014. [10]
