A carbon nanotube field-effect transistor (CNTFET) is a field-effect transistor that utilizes a single carbon nanotube (CNT) or an array of carbon nanotubes as the channel material, instead of bulk silicon, as in the traditional MOSFET structure. There have been major developments since CNTFETs were first demonstrated in 1998.
The Digital Invoice Customs Exchange (DICE) is a revenue protection idea developed to prevent tax evasion methods such as sales suppression in domestic trade and missing trader fraud, transfer pricing in cross-border trade. As such, the implementation of this idea enables Revenue Authority to have advance notice of every commercial transaction.
The electronic properties of individual CNT fibers (i.e. bundle of individual CNT) are governed by the two-dimensional structure of CNTs. The fibers were measured to have a resistivity only one order of magnitude higher than metallic conductors at 300 K (27 °C; 80 °F). By further optimizing the CNTs and CNT fibers, CNT fibers with improved ...
A single-walled carbon nanotubes (SWCNT) can be envisioned as strip of a graphene molecule (a single sheet of graphite) rolled and joined into a seamless cylinder.The structure of the nanotube can be characterized by the width of this hypothetical strip (that is, the circumference c or diameter d of the tube) and the angle α of the strip relative to the main symmetry axes of the hexagonal ...
CNT lengths range from less than 100 nm to 0.5 m. [1] Individual CNT walls can be metallic or semiconducting depending on the orientation of the lattice with respect to the tube axis, which is called chirality. MWNT's cross-sectional area offers an elastic modulus approaching 1 TPa and a tensile strength of 100 GPa, over 10-fold higher than any ...
The booming U.S. stock market will help keep the dollar expensive as global investors pour money into America, a foreign exchange strategist said. But the politics of any trade deals that the ...
Pet microchips help reunite lost animals with their owners. A Texas company suddenly closed, leaving pet owners worried about their pet's welfare.
UML class diagram depicting a invoice. Electronic invoicing (also called e-invoicing or einvoicing) is a form of electronic billing.E-invoicing includes a number of different technologies and entry options and is usually used as an umbrella term to describe any method by which a document is electronically presented from one party to another, either for payment [1] or to present and monitor ...
