The chemical process industry aims particularly at energy, capital expenditure and variable feedstock cost savings due to fierce global competition, the Kyoto Protocol and requirements for sustainable development. Increasingly conceptual process design methods are used in the industry to achieve these aims. They are used in: • existing processes to renew parts; • process re-designs based on exi...

Novel electrodes are needed for direct ethanol fuel cells with improved quality. Hierarchical engineering can produce catalysts composed of mesocrystals with many exposed active planes and multi-diffused voids. Here we report a simple, one-pot, hydrothermal method for fabricating Co3O4/carbon/substrate electrodes that provides control over the catalyst mesocrystal morphology (i.e., corn tubercl...

Cubic, octahedral, and rhombic dodecahedral Cu2O nanocrystals bound by respectively {100}, {111}, and {110} facets were successfully employed to catalyze the [3 + 2] cycloaddition reaction for the regioselective synthesis of 3,5-disubstituted isoxazoles. Surfactant-free nanocrystals having the same total surface area were used for the catalysis. Strongly facet-dependent organocatalytic activity...

Flame Spray Pyrolysis (FSP) is a well investigated high temperature aerosol technique for synthesizing nano-sized metal oxide catalysts of almost all metals and transition metals by gas-to-particle conversion (Teoh et al. 2010). However, specific designs of multi-component catalysts and the controlled dispersion of catalytic material on the support are limited with this approach. Double Flame S...

Introduction:  Gifted and talented students are the main customers and driving force of the education system, therefore, the existence of a permanent mechanism based on their demands, expectations, and problems seems necessary to improve the education system. Method: This qualitative study was done using conventional content analysis. The participants were 23 gifted and talented students of Te...
