Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups
(Univ Sao Paulo Fac Odontologia Bauru, 2014-07-01)
Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel ...
Further insight on recombination losses in the intrinsic layer of a-Si:H solar cells using computer modeling tools
(American Institute of Physics, 2017-05)
Recombination losses of a-Si:H based p-i-n solar cells in the annealed state are analyzed with device computer modeling. Under AM1.5 illumination, the recombination rate in the intrinsic layer is shown to be controlled by ...

Tin O2n-1 Magnéli phases studied using density functional theory
(2014-07-31)
Defects in the rutile TiO2 structures have been extensively studied, but the intrinsic defects of the oxygen-deficient TinO2n-1 phases have not been given the same amount of consideration. Those structures, known as Magnéli ...
