As the largest developing country in the world, China is urgently in short of energy and natural resources. However, biological resources such as crop residues are burnt in the field, which cause serious environmental pollution. Still it is not clear how much storage and potential of these huge...

The quantum conductance of two kinds of carbon nanotube quantum dots (CNQD) composed of (5,5) and (10,0) tubes, namely (10,0)/(5,5)/(10,0) and (5,5)/(10,0)/(5,5) with different quantum sizes, are calculated. It is shown that for (10,0)/(5,5)/(10,0) CNQD, one on-resonant peak at the Fermi energy...

We have theoretically studied electric-field-domain dynamics and current self-oscillations in dc-biased negative-effective-mass (NEM) p <Superscript> + </Superscript> pp <Superscript> + </Superscript> diodes. The formation and traveling of electric-field domains in the diodes are investigated in detail with a realistic treatment of the scatterings...</superscript></superscript>

In this paper, we establish the upper semicontinuity and lower semicontinuity of solution mappings to a parametric generalized strong vector equilibrium problem with setvalued mappings by using a scalarization method and a density result. The results improve the corresponding ones in the...

The ground source heat pump can reduce electrical energy requirements for the heating of buildings by up to 70% compared with electrical resistive heating; however, the cost of ground loop installation can be a disincentive to their use. Foundation structures, such as concrete piles, are...

Project tasks: Perform the necessary testing and development to demonstrate that the amount of binder in coal logs can be reduced to 8% or lower to produce logs with adequate strength to eliminate breakage during pipeline transportation, under conditions experienced in long distance pipeline...
