All articles of this category The search for conducting organic solids and other new materials has paved the way for many discoveries in the chemistry of the chalcogen-based heterocyclic compounds. This focused interest has especially influenced the investigations into 1,3-dithiole-2-thione-4,5-dithiolate (DMIT) and i…
A large optical-aperture membrane diamond anvil cell designed for infrared spectroscopy is described. The cell offers definite advantages compared to existing systems. Other possibilities concerning x-ray diffraction analyses with the cells are mentioned.

[Fe(heidi)(H2O)]2, where H3heidi = N(CH2COOH)2(CH2CH2OH), crystallizes in a triclinic space group P̅1, with a 6.838(1), b 7.058(1), c 9.676(2) Å, α 103.29(1), β 93.58(1), γ 97.83(1)° and is a dinuclear Fe(III) compd. with the two Fe atoms linked by the alkoxide function of the ligand. The dinucleating ability of this…
A detailed study has been carried out to explain the influence of Pp^ in silicate phases and in industrial raw meals upon their mineralogical compositions. Some compositions in the lime rich portion of the CaO-SiO2-P2O5 system are studied using laboratory reactants. The results showed that the compositions lying in th…
The aim of this study is to establish which physical properties may be used, in a routine way, in order to know the efficacy rate of a treatment applied on a specific rocky substrate. Whit this purpose, two types of carbonated rocks, the limestone of Hontoria (Burgos) and the dolomite of Laspra (Asturias) have been ch…
The aim was to reproduce, in an accelerated way in the laboratory, the transformations of what is known as alkaline hydrolysis and observe the results on the properties of the system. To do this, mortars of aluminous cement were made up, a part of which underwent thermic treatment. They were then carbonated under vari…
The most aggressive situation which is responsible for most of the cases of steel reinforcement corrosion in concrete, takes place when chlorides are present in the environment. These chlorides destroy the passivating film of steel and promote the denominated pitting corrosion. In order to study the demonstrated corro…
