Pharmaceutical impurities and degradation products: Uses and applications of NMR techniques
(Elsevier, 2014-04)
Current standards and regulations demand the pharmaceutical industry not only to produce highly pure drug substances, but to achieve a thorough understanding of the impurities accompanying their manufactured drug substances ...
Impurity states in the narrow band-gap semiconductor n-type InSb
(1996)
We investigate impurity pair and triad formations in the narrow band-gap semiconductor n-doped InSb. It is found that in the region of the band-gap energy, Eg = 0.23 eV, at 0 K, the effects of such clusters play a relevant ...
The two-impurity Anderson model: An effective medium approach
(2002-03-01)
The two-impurity Anderson model is solved within a effective medium approach. All impurity parameters are modelled via Slater atomic orbitals. Impurity spectral densities and spin correlation functions are readily computed. ...

Raw sugarcane classification in the presence of small solid impurity amounts using a simple and effective digital imaging system
(2019-01-01)
Specific amounts of solid impurities in raw sugarcane need to be detected before raw materials are carried into mills. Solid impurities come from the plant, e.g., green and dry leaves and soil. This study proposed to ...
Three-body bound states of two bosonic impurities immersed in a Fermi sea in 2D
(2016-04-01)
We consider two identical impurities immersed in a Fermi sea for a broad range of masses and for both interacting and non-interacting impurities. The interaction between the particles is described through attractive ...
Hydrostatic pressure, impurity position and electric and magnetic field effects on the binding energy and photo-ionization cross section of a hydrogenic donor impurity in an InAs P¨oschl-Teller quantum ring
