Cl-BODIPYs: a BODIPY class enabling facile beta-substitution
(2012-01)Cl-BODIPYs, synthesized in high yields from dipyrrins under air- and moisture-free conditions, are extremely facile to substitution at boron compared to their corresponding F-BODIPYs, opening up a new route to BODIPYs ... -
Classifying donor strengths of dipyrrinato/aza-dipyrrinato ligands
(2019)A parameter is reported by which to use 13C NMR chemical shifts to measure and predict the donor capabilities of N^N dipyrrinato and aza-dipyrrinato ligands chelating in L^X fashion. The results enable the rationalisation ... -
A Combinatorial Investigation of Fe-Si-Zn Thin Film Negative Electrodes for Li-ion 1 Batteries (Preprint)
(IOP Publishing, 2014-12-04)Thin-film Fe-Si-Zn libraries were investigated as negative electrode materials for Li-ion batteries using combinatorial and high-throughput techniques. X-ray diffraction and electron microprobe measurements were used to ... -
A Combinatorial Investigation of Fe-Si-Zn Thin Film Negative Electrodes for Li-ion 2 Batteries (Preprint)
(IOP Publishing, 2014-11-07)Sodium-ion batteries have the potential to be a low cost, sustainable replacement for lithium-ion batteries in large scale energy storage. The lack of practical negative electrode materials limit the development of Na-ion ... -
Combinatorial Investigations of Ni-Si Negative Electrode Materials for Li-Ion Batteries
(IOPscience, 2015-06-30)Sputtered thin films in the Ni-Si system (0 ≤ x ≤ 0.65 in NixSi1-x) were studied for use as anode materials in Li-ion cells. All compositions were found to be amorphous. The Ni in Ni-Si films was found to suppress the ... -
Combinatorial Study of the Si-Sn-O System as Negative Electrode Materials in Li-Ion Cells
(The Electrochemical Society, 2015-11-17)SixSnyO1-x-y films with 0.45 < x < 0.80, 0.05 < y < 0.35, and 0.05 < (1-x-y) < 0.40 have been prepared using a magnetron sputtering method. All compositions had an amorphous structure and good capacity retention. Reversible ... -

Density-operator theory of orbital magnetic susceptibility in periodic insulators
(2011-08)The theoretical treatment of homogeneous static magnetic fields in periodic systems is challenging, as the corresponding vector potential breaks the translational invariance of the Hamiltonian. Based on density operators ... -
Designing glass with non-dispersive stress-optic response
(Elsevier, 2016-02-01)The dispersion of the stress-optic response of a series of barium and lead phosphate glasses is measured using an ellipsometric method. It is found that the barium glasses display consistently positive dispersion with ... -
Deuteration and Tautomeric Reactivity of the 1-Methyl Functionality of Free-base Dipyrrins
(Organic and Biomolecular Chemistry, 2017)Regioselective reactivity of the 1-methyl group of free-base dipyrrins is explored, including discussion of tautomerism to provide exocyclic alkenyl reactivity. Deuterium is installed such as to generate dipyrrins substituted ...
