This paper reports on the fabrication and experimental characterisation of improved design AC eletroosmotic micropumps. Since the first study and analysis of AC electroosmosis by Ramos et al. [1], many devices have been fabricated and tested [2]. The basic ...
Numerical investigation of the unsteady flow patterns around the bucket can be helpful to improve the Pelton turbine efficiency. In fact, by studying the loss mechanisms in the flow, one can optimize the bucket design. For this purpose, an accurate investi ...
Solar-driven non-stoichiometric thermochemical redox cycling of ceria for the conversion of solar energy into fuels shows promise in achieving high solar-to-fuel efficiency. This efficiency is significantly affected by the operating conditions, e.g. redox ...
The thermochemical emission of alkali metals from biomass samples and two organic salts was investigated for the first time using a novel combination of a th ermogravi metric analyzer with a jet flow condenser attached to a surface ionization detector. Thi ...

High-purity HSO3Cl is prepd. at a high space-time yield by mixing and reacting gaseous HCl with SO3 dissolved in ClSO3H, contg. 0.3-1.4% SO3 at 70-100 Deg in a venturi tube at 1-1.1 mol HCl/mol SO3. Thus, into the throat of a vertical venturi tube was fed ...
