The ozonization at the vacancy defect site of the single-walled carbon nanotube has been studied by static quantum mechanics and atom-centered density matrix propagation based ab initio molecular dynamics within a two-layered ONIOM approach. Among five different reaction pathways at the vacancy defect, the reaction involving the unsaturated active carbon atom is the most probable pathway, where...

The purpose of food packaging is to preserve the quality and safety of the food it contains from the time of manufacture to the time it is used by the consumer. Recently, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology. One such development is the active food packag...

Halides were used as the precursors to prepare various kinds of materials by stripped off the halogens. Metals, metal silicides and carbon related materials could be prepared by using metal halides, silicon halides and carbon halides as the precursors. Some active metals and active meta stable species were used as stripping reagents.

Replacement of noble metals in catalysts for cathodic oxygen reduction reaction with transition metals mostly create active sites based on a composite of nitrogen-coordinated transition metal in close concert with non-nitrogen-coordinated carbon-embedded metal atom clusters. Here we report a non-platinum group metal electrocatalyst with an active site devoid of any direct nitrogen coordination ...

In this mentioned study for sea water treatment ceramic composites were made from natural alumina and adsorbent active ingredients. According to the experimental results, filters along with active agents have acceptable effects on drinking water parameters and contaminants in compare with 1053 ISIRI standard. Modular set up was made for sea water treatment tests. Water flowrate after filtration...
