Our group has been developing x-ray microcalorimeters consisting of neutron transmutation doped (NTD) germanium thermistors attached to superconducting tin absorbers. We discuss the performance of single pixel x-ray detectors, and describe an array t
We have developed a new massively-parallel radiation-hydrodynamics code (Cosmos) for Newtonian and relativistic astrophysical problems that also includes radiative cooling, self-gravity, and non-equilibrium, multi-species chemistry. Several numerical

Composite microcalorimeters using neutron transmutation-doped germanium (NTD) thermistors have been tested at hard x-ray energies. We present a broad band spectrum showing the energy resolution at 60 keV to be approximately 50 eV. The application of

Thirtyfour complexes of 1,2-bis(methylphenylarisino)ethane (dase) and 1,3-bis(methylphenylarsino)propane (dasp) have been characterised. Interesting differences are observed in the complexing properties of these chelates. Thus, with cobalt(II) halide

o -Phenylenebis(diphenylstibine) (sbsb) has been obtained from sodium diphenylstibide and o -bromophenyldiphenylstibine. The failure of other routes to this compound, and of attempts to prepare ethylenic distibines, are discussed.

Lithium dimethylphosphide prepared from lithium and PMe2Ph in tetrahydrofuran reacts with o-dichlorobenzene to produce o-phenylenebis(dimethylphosphine). Similar reactions using the appropriate o-bromophenyl derivatives o-C6H4Br(Y)(Y = NMe2, AsMe2, o

Two potentially quadridentate chelating ligands containing bismuth atoms have been synthesised: tris(o-dimethyl-arsinophenyl) bismuthine (L1) and tris(3-dimethylarsinopropyl)bismuthine (L2). Reaction of L1 with nickel(II) salts produces the essential
