Friction is an unavoidable natural phenomenon. The fuel used to reduce the friction and wear of mechanical parts each year accounts for 1/3 of the total fuel consumption. Besides, friction can cause unproductive loss of mechanical energy, sh…
Molybdenum disulfide used for nanoelectromechanical system with ultra-thin, ultra-small, ultra-low power consumption.…
Copper oxides are unusual in two respects. First, octahedral-site CuII:t6e3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and, therefore, a strong Jahn–Teller ion; consequently, CuII ions normally occupy square coplana...…
The Ti-doped Bi 2 Te 3 with concentrations 1, 3, and 5 in % Ti were synthesized using a simple powder metallurgy method. It is revealed that the optimum Ti addition in parent material changes the conduction type from undoped n-type into p-type with 1...…
