Single-electron devices can be built using a metal nanoparticle as an island between two electrodes: one electron at a time is passing the nanoparticle "island" between the electrodes = the island behaves as a Coulomb blockage. When a Pb nanoparticle is used in a device, each Coulomb staircase step is measured to be 0.52 eV (the radius of Pb particle is 4.2 nm).a) Calculate what is the maximum temperature (in K) where the Coulomb blockage phenomenon can be observed for a such a Pb nanoparticle single-electron device (hint: thermal energy kBT)?b) What is the maximum temperature where the Coulomb blockage phenomenon can be observed for a bulk Pb electrode with 1.0 cm2 surface area (capacitance of bulk lead is 16.1 μF/cm2)?

"the periodic table is arranged in order of atomic number."

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
