Aug 19, 2021
Tripodal ligands with main group bridghead units are well established in coordination chemistry and single-site organometallic catalysis. Although a large number of tris(2-pyridyl) main group ligands [E(2-py)3] (E = main group...
Bond graph-based filtered inversion of multivariable physical systems
Roger F Ngwompo
Jan 01, 2012
In a variety of fields, system inversion is often required in order to determine inputs from measured or for desired outputs. However, inverse systems are often non-proper in the sense that they require differentiators in their...
Dynamic Interfacial Adhesion through Cucurbit[n]uril Molecular Recognition.
Supramolecular building blocks, such as cucurbit[n]uril (CB[n])-based host-guest complexes, have been extensively studied at the nano- and microscale as adhesion promoters. Herein, we exploit a new class of CB[n]-threaded highly...
