Abstract: Novel imidazolium salts of formula (I) are described in which R is a C1-C14 alkyl group, optionally substituted by one or more fluorine atoms, or a C2-C18 alkoxyalkyl group, R? is an alkyl group containing at least 8 carbon atoms, at least 6 of which are partially or entirely fluorinated, R? is hydrogen or C1-C3 alkyl, Z is an organic or inorganic anion, and Q is further defined. The compounds of formula (I) are liquid crystals over a wide temperature range, and are characterized by high conductivity, hydrophobicity and stability. These properties made them ideally suitable for use in devices based on electrochemical reactions, such as solar cells, fuel cells, electrochemical sensors, lithium batteries and capacitors, etc.

Abstract: A method for cutting an underwater structure below the level of the seabed on which it is installed is described. The method has the following steps: positioning cutting means and penetrating means associated with the cutting means in close proximity to the underwater structure to be cut, at the intersection region between the structure and the seabed; causing both the penetrating means and the cutting means associated therewith to penetrate into the seabed in a substantially longitudinal direction to a portion of the structure which is embedded in the seabed; and actuating and driving the cutting means and the penetrating means in a substantially perpendicular direction to the embedded portion so as to cut the structure below the level of the seabed. An apparatus for carrying out the method is also described.

Abstract: The present invention relates to a process for the preparation of materials with nanometric dimensions and controlled shape, based on titanium dioxide. The invention also relates to a process for the preparation of titanium dioxide nanorods and nanocubes with anatase phase composition, which are highly suitable for photocatalytic use, in particular for applications involving photovoltaic cells, for example Dye Sensitized Solar Cells (DSSC), photoelectrolysis cells and tandem cells for the conversion of solar energy and the production of hydrogen.

Abstract: A machine for cutting structural members is described. The machine has an endless travelling wire and a frame arranged around a structural member to be cut. The travelling wire and frame have longitudinal track with carriages with at least one pulley carrying at least one cutting segment. The longitudinal tracks are adapted to be engaged via motion means in arcuate guide slots.

Abstract: The method relates to the manufacture of a reinforced diamond-coated cable for cutting structures and materials of steel, concrete, steel and concrete, stone materials or the like, in which such diamond-coated cable comprises a plurality of outer strands (101) of metal material such as steel or the like wound in a helix around an inner central strand (201) and a series of sheaths (2) inserted along such outer strands (101) and having on their external profiles (202) projecting members of strongly abrasive materials such as industrial diamonds or the like.

Abstract: A method is provided for cutting and removing underwater pipelines. The method comprises (a) determining the position of the underwater pipeline to be removed;(b) positioning, on the line a guide for positioning a cutter and a device for recovering the cut pipe sections, the guide being able to be repositioned along the line and being stably connected to a boat intended to collect the recovered sections; (c) guided positioning of the cutter and guided positioning of the device for recovering the cut pipe; (d) cutting of the pipe section of predetermined length and subsequent removal of the section by using the device for recovering the cut pipe; (e) transfer of the pipe section recovered by the recovery device to the boat; and (f) repositioning of the guide along the remaining line portion to be removed and repetition of the preceding steps(c) to(e) until the underwater pipeline has been completely removed. An apparatus for implementing this method is also provided.

Abstract: A method for the cutting of underwater structures below the level of the sea bottom on which they are installed, comprises determining an ideal plane of cutting, having considered the characteristic features of the structure i.e. its morphology and its positioning on the bottom, the shape and consistency of the bottom itself, and the depth below the level of the bottom at which the cut must be effected; positioning and anchoring of a cutter in proximity of the cutting area; obtainment of at least one perforation or boring in proximity of the structure through the bottom at least up to the predetermined level for the cutting of the structure, along a direction parallel to the cutting direction and preferably lying on the cutting plane; and introduction of the cutter inside the perforation or boring and cutting of the structure. An apparatus for carrying out the method is also provided.
