A nanoporous carbon-loaded cement composite that conducts electricity. The nanoporous carbon-loaded cement composite can be used in a variety of different fields of use, including, for example, a structural super-capacitor as an energy solution for autonomous housing and other buildings, a heated cement for pavement deicing or house basement insulation against capillary rise, a protection of concrete against freeze-thaw (FT) or alkali silica reaction (ASR) or other crystallization degradation processes, and as a conductive cable, wire or concrete trace.

Electron conducting carbon-based cement

The invention relates to a method for manufacturing macroscopic fibers of titanium dioxide (TiO) by continuous extrusion in a one-way flow, to the macroscopic fibers of TiOthat can be obtained by such a method, to the use of said fibers in heterogeneous photocatalysis for decontamination of organic pollutants from gaseous environments, and to a method for decontaminating gaseous environments, in particular air, using such fibers.

A process is provided for preparing an inorganic material in the form of an alveolar monolith of a silica matrix where the monolith includes interconnected macropores. The process includes at least one step of mineralizing an oil-in-water emulsion formed from droplets of an oily phase dispersed in a continuous aqueous phase and in which colloidal solid particles are present at the interface formed between the continuous aqueous phase and the dispersed droplets of oily phase. Such materials obtained according to this process may be used, especially for separative chemistry and filtration, for performing chemical reactions catalyzed in heterogeneous phase, as thermal or phonic insulators, or as templates for manufacturing controlled-porosity carbon skeletons.
