Evaporation from porous media is a key process in the hydrologic cycles, waste isolation, biological and food processes and other engineering application. Drying rate and patterns in porous media are strongly influenced by transport properties of the mediu ...
Easy does it: The unique properties of benziodoxolone alkynyl periodinane 1 and gold catalysts have allowed the development of a high yielding, operationally simple (room temperature, no dry solvents or inert conditions, commercially available catalyst) re ...
This thesis aims to find, for the first time, a direct relation between the size and morphology of small metallic nanostructures (gold in this case) supported on a metal-oxide surface to their catalytic activity. In this perspective, three main topics have ...
Calcium Aluminate Cements (CAC) are renowned in the field of construction for specific applications requiring rapid hardening and chemical resistance. These properties result from rapid exothermic reactions occurring immediately after setting. Due to the m ...
We designed block copolymer pro-amphiphiles and amphiphiles for providing very long-term release of nitric oxide (NO). A block copolymer of N-acryloylmorpholine (AM, as a hydrophile) and N-acryloyl-2,5-dimethylpiperazine (AZd, as a hydrophilic precursor) w ...
Evaporative drying of porous media is jointly controlled by external ( atmospheric) conditions and by media internal transport properties. Effects of different atmospheric potential evaporative demand on observed drying rates were studied in a series of la ...
The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...
The thermal decomposition of three synthetic copper sulfides (chalcocite (Cu2S), chalcopyrite (CuFeS2), and enargite (Cu3AsS4)) and two commercial copper concentrates has been studied on a thermobalance (T = 1173-1773 K) and an imaging furnace (T approxima ...
