Background and objectives: Endometrial polyps in asymptomatic postmenopausal women are often incidentally found, yet only 1.51% of them are malignant. Their potential for malignant transformation has not been adequately addressed. The aim of this stu

Decomposition of hydrazinium pentafluoroaluminate under oxidative (F 2 ) conditions leads to aluminium(III) fluoride whose properties are highly dependent on the conditions used for synthesis. In the presence of anhydrous HF, which probably acts as a

The behaviour of the sol–gel prepared, amorphous solids, high surface area (HS) aluminium fluoride and magnesium fluoride in promoting room temperature dehydrochlorination of tert -butyl chloride (Bu t Cl), in their catalytic activity for the dismu

Acid–base reactions and interactions are at the heart of inorganic fluorine chemistry and are now recognised as forming a very important part of the chemistry, catalytic or non-catalytic, that occurs on inorganic fluorinated surfaces. This review t

The hydrodechlorination of CF3CCl2F over Pd and Pt supported on β-AlF3 and MgF2 with D2 gas has been investigated employing temperature programmed isotope exchange (TPIE) under static conditions. The isotope exchange observed between the H-loaded me

The preparation and characterisation of two series of fluorinated chromia aerogel materials, lightly doped with zinc(II) or magnesium(II), are described. They behave as heterogeneous catalysts for transformations of 1,1,2-trichlorotrifluoroethane und

Palladium or platinum supported on β-aluminium(III) fluoride or magnesium fluoride are effective catalysts for the conversion of the ozone-depleting compound, CCl2FCF3, to the environmentally acceptable refrigerant, CH2FCF3 (HFC-134a). The gas phase

A [ 36 Cl ] radiotracer study of the behaviour of 1,1,2-trichlorotrifluoroethane on β-aluminium(III) fluoride at elevated temperature indicates that the isomerisation of CCl2FCClF2 to CCl3CF3 occurs by an intramolecular process. Isomerisation is fol

The differences in the dynamic behaviour of 1,1,2-trichlorotrifluoroethane over fluorinated alumina or chromia catalysts at moderate temperatures are significant. Alumina-based catalysts favour the isomerization of CCl 2 FCClF 2 followed by the dismu

Conversion of CCl 2 FCClF 2 to CCl 2 FCF 3 is achieved in the temperature range, 593–713 K, under flow conditions by using the catalysts, β-AlF 3 or γ-alumina, prefluorinated with CCl 2 F 2 or SF 4 . Aluminium-based catalysts favour the formation
