Nanostructures have considerably higher surface areas than their bulk counterparts; thereforesurfaces often play important, sometimes even dominant, roles in the nanostructure properties. Thenanocrystalline and nanotubes have low band gaps and high carrier mobility, thus offeringappealing potential as absorption gas. Interaction between methanol molecules and carbonnanotube is investigated usin...

Manufacturing enterprises nowadays face the challenge of increasing energy price and emission reduction requirements. An approach to reduce energy cost and become environmental friendly is to incorporate energy consumption into consideration while making the scheduling plans. The research presented by this paper is set in a classical job shop circumstance, the model for the triple objectives pr...

in recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...
