In recent years, more and metal oxides have been finding critical tribo-catalytic applications. Presently, we explored the conversion of H2O CO2 using Co3O4 nanoparticles obtained some surprising results. an as-received 150 mL glass reactor enclosed with 10 H2O, 0.10 g nanoparticles, 1 atm CO2, a Teflon magnetic rotary disk, obse...

exploratory bouts in a novel environment? The only way to find out will be to record chronically across multiple units and cortical layers during the actual behavior and plasticity process. Finally, how such a shift in excitatory–inhibitory balance might be achieved is of interest. The brevity of the exploratory behavior required for bidirectional map changes is suggestive. Remarkably, just 4 m...

Solid state recycling (SSR) is a new approach for making metals more efficient with respect to remelting-based approaches. Friction stir consolidation (FSC) solid-state process that employed recycle metallic scraps. Until now, single-step FSC was applied recycled metal chips. During the approach, critical processes parameters, especially processing time and rotational speed, are considered vita...

Global warming and depletion of resources have fueled research towards innovative building materials low environmental impact high performance engineering properties. Porous glass-ceramics were synthesized using municipal solid waste incinerator (MSWI) bottom ash (BA) as a starting material. BA was initially milled then vitrified, purification step, by direct microwave heating, characterized gl...

Stirring rates in heterogeneous catalytic reactions have an effect on reaction rates. When conducting small-scale surveys using a single central stir plate, reaction vessels in different positions experience slightly levels and patterns of agitation. We probed this by running the same 40 times, varying rate (fast/slow) and vial position two 3D printed holders. found variability conversion (meas...

There are many industrial situations where rods are used to stir a fluid, or where rods repeatedly stretch a material such as bread dough or taffy. The goal in these applications is to stretch either material lines (in a fluid) or the material itself (for dough or taffy) as rapidly as possible. The growth rate of material lines is conveniently given by the topological entropy of the rod motion....

In the context of a bioreactor, cells are sensitive to cues from other cells and mechanical stimuli from movement. The ability to provide the latter in a discrete fluidic system presents a significant challenge. From a prior finding that the location of the focus of a laser below particles relative to the beam axis producing a pushing effect in a predominant lateral sense, we advance an approac...

A  facile  effective  stirring  aging  at  room  temperature  prior  to  conventional  hydrothermal treatment was employed in the template-free synthesis of micro- and nano-crystalline sodalites with  two  different  initial  gel  compositions.  The  effect  of  initial  Si/Al  molar  ratio,  NaOH concentration and stirring aging time were investigated on the morphology and particle size of the...
