Chemical Constituents from Stem Bark and Roots of Clausena anisata
(2012-11)
Phytochemical investigations on the stem bark and roots of the tropical shrub Clausena anisata
led to the isolation and characterization three carbazole alkaloids: girinimbine, murrayamine-A and
ekeberginine; two peptide ...
Synthesis and characterisation of the unsubstituted dipyrrin and 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene: improved synthesis and functionalisation of the simplest BODIPY framework
(2013)
An improved and scalable synthesis of the unsubstituted
4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported
parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a- ...
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 ...
Synthesis of natural products containing the pyrrolic ring
(2010)
This review provides an overview of the synthetic chemistry that has been utilised to prepare
natural products containing a pyrrolic ring.
Conversion of F-BODIPYs to Cl-BODIPYs: Enhancing the Reactivity of F-BODIPYs
(2013-01)
A new method for the synthesis of Cl-BODIPYs from F-BODIPYs is reported, merely requiring
treatment of the F-BODIPY with boron trichloride. Cl-BODIPYs are exploited as synthetic
intermediates generated in situ for the ...
Thermal conductivity of (Er1-xYx)(2)Ti2O7 pyrochlore oxide solid solutions
(2012-08)
The thermal conductivities of pyrochlore oxide solid solutions of general formula
(Er1-xYx)(2)Ti2O7 with 0 <= x <= 1 have been determined for high-quality single crystals
aligned along the [110] direction, over the ...
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 ...
Investigations into the nucleophilic meso-substitution of F-BODIPYs and improvements to the synthesis of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene.
(2011)
A series of three F-BODIPYs, with varying levels of steric crowding about the meso-position were
selected to investigate nucleophilic meso-substitution of F-BODIPYs. The synthesis of one of these
F-BODIPYs, 4,4-difluor ...
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 ...
Thermal, vibrational, and thermoelastic properties of Y2Mo3O12 and their relations to negative thermal expansion
(American Physical Society, 2014-07-21)
Y2 Mo3O12, a material that exhibits negative thermal expansion (NTE) from 10 to 1173 K, offers an excellent opportunity to examine relationships between NTE and other physical properties over a wide temperature range. We ...
