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...

Mode switching in causally dynamic hybrid bond graphs
The causally dynamic hybrid bond graph is extended to the case of mode-switching behaviour. Mode-switching 'trees' of switches and elements are historically used by bond graph practitioners to represent elements with...
Hydrogen-Bond-Assisted Symmetry Breaking in a Network of Chiral Metal-Organic Assemblies.
Herein we elucidate the interplay of chiral, chelate, solvent, and hydrogen-bonding information in the self-assembly of a series of new three-dimensional metal-organic architectures. Enantiopure ligands, each containing H-bond...
