उदाहरण वाक्य
मोबाइल
- In photosynthetic purple bacteria the antenna complexes function as light-harvesting systems that absorb light radiation and transfer the excitation energy to the periplasmic domain.
- When the excited molecule has a nearby neighbour molecule, the excitation energy may also be transferred, through electromagnetic interactions, from one molecule to another.
- He experimented on fission isomers ( e . g . excitation functions, excitation energies, isomeric yield, half-life measurements, angular correlations ).
- It appears in green sulfur bacteria and mediates the excitation energy transfer from light-harvesting chlorosomes to the membrane-embedded bacterial reaction center ( bRC ).
- The best way to handle this problem is to keep a set of discrete levels at low excitation energies and a set of binned levels at high energies.
- Ruthenium complexes typically have large Stokes shifts, and therefore have low energy emission wavelengths and small zero-zero excitation energies, when compared to iridium complexes.
- It has been found, however, that the chemiluminescence intensity corrected for quantum yield decreases as the singlet excitation energy of the fluorescent molecule increases [ 6 ].
- Using this measurement method, the dielectric constant may exhibit a resonance at certain frequencies corresponding to characteristic response frequencies ( excitation energies ) of contributors to the dielectric constant.
- Particles produced in process 1 ) will have higher energies than those due to process 2 ), because in the latter process the excitation energy is in part degraded.
- Unfortunately this can not be done easily because there is similar response to the feeding of adjacent levels when they are at high excitation energies where the level density is high.
- He has written extensively on the topic of Photosynthesis, including on the role of chlorophyll in Photosynthesis, light absorption, excitation energy transfer, and how plants make oxygen.
- In other words, the excimer formation is a crucial step needed for efficient transformation of the atomic excitation energy to the radiation energy in an ultra-high pressure environment.
- For example, a solid with two identical phonons does not have exactly twice the excitation energy of a solid with just one phonon, because the crystal vibration is slightly anharmonic.
- Under changing light conditions, the reversible phosphorylation of light harvesting chlorophyll a / b binding proteins ( LHCII ) represents a system for balancing the excitation energy between the two photosystems.
- Clark, David D .; Kostroun, V . O .; Siems, Norman E . Identification of an isomer in silver-110 at 1-keV excitation energy.
- "' Cooperative luminescence "'is the radiative process in which two excited ions simultaneously make downward transition to emit one photon with the sum of their excitation energies.
- At lower excitation energy ( see neutron evaporation ), the effect of the shell will be enhanced and ground-state nuclei can be expected to have relatively long half-lives.
- In cold fusion reactions, the produced fused nuclei have a relatively low excitation energy ( ~ 10 20 MeV ), which decreases the probability that these products will undergo fission reactions.
- There are further parameters influencing the luminescence of thermographic phosphors, e . g . the excitation energy, the dopant concentration or the composition or the absolute pressure of the surrounding gas phase.
- One isotope, 229 Th, has a nuclear isomer ( or metastable state ) with a remarkably low excitation energy, recently measured to be 7.6 ?0.5 eV.
