Quantum Dot:
Patent
number 60-985-841 is for a quantum dot that only emits and absorbs three wavelengths of light. The quantum dot is engineered to have three different electron energy levels: E₁=0.60 eV, E₂ = 2.53 eV, and E3 = 4.15 eV. The quantum dot contains a
electron.

Report your result in nanometers (nm).
One molecule of ATP provides 0.3 eV when used by the cell. Photosynthesis in a typical plant uses 8 photons at the nominal wavelength of 525 nm to produce 1 ATP. What percentage of the light energy is converted into chemical energy in the form of ATP? Give your answer to 2 significant digits.

Concentrate on lead element. All isotopes are listed in the table. Isotope masses are listed in AMU (atomic mass unit) and value of AMU is given in Physical Constants section below this document together with other physical constants.
An ionizing laser is directed onto the lead block under test such that the ionized atoms (or isotopes) leaves the lead block with an initial kinetic energy of 1 eV. The direction is conically upward but sure that the cone is larger than the entrance hole to the accelerator section. The ionized isotopes are in form. That is only a single electron is missing in lead ions. The number of ionized isotopes entering into the accelerator region corresponds to a ion current.
These ions are accelerated with a constant DC voltage in the acceleration chamber which is in the form of two parallel metal plates that have a hole in both bottom and top.
Then the ions enter to velocity selector region. In this region both electric and magnetic fields are applied. Next…

- Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. One potential application of nanotechnology is the construction of artificial cells. The simplest cells would probably mimic red blood cells, the body's oxygen transporters. For example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. If the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive.
