Synthesis of symmetric meso-H dipyrrin hydrobromides from 2-formyl pyrroles
(Synlett, 2014)The reaction of 2-formyl pyrroles in acidic methanol gives the corresponding symmetric, meso-H 4,6-dipyrrin hydrobromides. This convenient strategy involves initial deformylation under the acidic conditions, followed by ... -
Synthesis, Lithium Insertion and Thermal Stability of Si–Mo Alloys
(The Electrochemical Society, 2020-10-05)Li insertion was investigated in SixMo100−x (90 ≥ x ≥ 70, Δx = 10) alloys prepared by mechanical ball milling. X-ray diffraction (XRD) and quantitative phase analysis were used to analyze phase compositions of these Si–Mo ... -
Synthesis, properties and reactivity of BCl2 aza-BODIPY complexes and salts of the aza-dipyrrinato scaffold
(Royal Society of Chemistry, 2020-02-25)The synthesis and characterisation of the BCl2-chelated complexes of both archetypal aza-dipyrrin sub- types are presented. A stepwise halogen exchange, leading to a mixed-halide Cl–B–F intermediate, is implicated in the ... -

Synthetic studies toward the kempane diterpenes. Construction of a key tricyclic intermediate
(2005)A synthetic sequence is described for construction of the tricyclic portion (35) of kempane diterpenes. The central stereochemistry was established by a Diels-Alder addition of 2,6-dimethyl-para-benzoquinone to a 5-membered, ... -

Technique for determination of accurate heat capacities of volatile, powdered, or air-sensitive samples using relaxation calorimetry
(2006-09)We introduce a four-step technique for the accurate determination of the heat capacity of volatile or air-sensitive samples using relaxation calorimetry. The samples are encapsulated in a hermetically sealed differential ... -
Temperature dependence of thermal conductivity enhancement in single-walled carbon nanotube/polystyrene composites
(2010-02)The thermal conductivity of single-walled carbon nanotube (SWCNT)/polystyrene composites, prepared by a method known to produce a uniform distribution of SWCNT bundles on the micrometer length scale, was measured in the ... -
Temperature dependent lattice misfit and coherency of Al3X (X = Sc, Zr, Ti and Nb) particles in an Al matrix
(Elsevier, 2015-05-01)The lattice coherency and critical radii for Al3X precipitates in an aluminum matrix were computed using first-principles methods. From density functional perturbation theory and the quasi-harmonic approximation, the unit ... -
