The principles of infrared emission spectroscopy are briefly reviewed with emphasis on the aspects of its application to the study of chemisorbed species. The ma in problems of sample preparation, selection of measurement conditions and the most suitable methods of data treatment are discussed. IR emittance spectra of two typical support materials for supported metal catalysts, aJumina and sili...

alumina-supported cs3[re(c2o4)3] precursor has been synthesized  for preparation of re-cs/g-al2o3 catalyst. cs3[re(c2o4)3]  has been prepared from the reaction of recl3 with  h2c2o4.2h2o and cscl in water. the complex has been characterized by elemental analysis and various spectroscopy techniques such as ft-ir, uv-vis and 13c-nmr. the complex was supported on γ-al2o3 by column chromatography. ...

Rhenium complexes functionalised with thioester-terminated alkyl chains can be attached to gold nanoparticles to yield water-soluble, visibly luminescent Re-GNP hybrid conjugates.

A new photo-active rhenium(I) bipyridyl based rotaxane has been synthesised which by virtue of the unique interlocked structural cavity selectively senses hydrogensulfate using luminescence spectroscopy.

The replacement of one pyrazole ligand by 2-aminopyridine in previously known rhenium tricarbonyl pyrazole complexes leads to more selective anion hosts.

Potential dual-mode monopropellant/electrospray capable binary mixtures of hydroxyl ammonium nitrate with ionic liquid fuels [Bmim][NO3] and [Emim][EtSO4] are synthesized and tested for monopropellant ignition capability in a micro reactor setup. The setup is benchmarked using 30% hydrogen peroxide solution decomposed via silver catalyst. Results show similar trends, but variance in the quantit...

Multi-step electron transfer is increasingly recognized as a means for moving charge in biological systems over long distances rapidly. Many postulated multi-step mechanisms rely on the formation of organic radicals (amino-acid radicals, nucleobase radicals) as intermediate electron or “hole” carriers. In this thesis, the multi-step mechanism for electron transfer in both proteins and DNA is in...

Through comprehensive density functional calculations, we predict the stability of a rhenium-based ferrite

UNLABELLED Colloidal particle size is an important characteristic to consider when choosing a radiopharmaceutical for mapping sentinel nodes in lymphoscintigraphy. METHODS Photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM) were used to determine the particle size of antimony trisulfide and rhenium sulfide colloids, and membrane filtration (MF) was used to determi...

The photophysical and photochemical properties of the new tricarbonyl rhenium(I) complexes bound to N-heterocyclic carbene ligands (NHC), fac-[Re(CO)3(N^C)X] (N^C = 1-phenyl-3-(2-pyridyl)imidazole or 1-quinolinyl-3-(2-pyridyl)imidazole; X = Cl or Br), are reported. The photophysics of these complexes highlight phosphorescent emission from triplet metal-to-ligand ((3)MLCT) excited states, typica...
