High‐temperature thermionic electron emission from different types of individual suspended carbon nanotubes (CNTs) in a homemade chip is studied. When collecting emission electrons with an external electrode, it is found that the collecting electric field influence the transport current in the CNTs, and the thermionic electron emission deviated from the traditional thermionic electron emission model...
In petroleum and petrochemical industry, spillage and overflow of petroleum products produce crude oil on the ground, which is soil environment problem. Some ingredients in the oil, especially PAHs, can be accumulated in agricultural products to enter the food chain, and, may produce “three cause” effects (teratogenic, cancer, mutation), which is harmful to both human health and ecological environmental...
