The competitive NMDA antagonist CPP protects substantia nigra neurons from MPTP-induced degeneration in primates [PDF]

, 1993
Degeneration of nigrostriatal dopaminergic neurons is the primary histopathological feature of Parkinson's disease. The neurotoxin MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) induces a neurological syndrome in man and non-human primates very ...

1-Ammonio-1-phosphonopentane-1-phosphonic acid

Acta Crystallographica Section E, 2008
The title compound, C5H15NO6P2, was obtained by the reaction of pentanenitrile with PCl3 followed by the dropwise addition of water. The asymmetric unit contains one molecule, which exists as a zwitterion with a positive charge on the –NH3 group ...

Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

Advanced Electronic Materials, EarlyView.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...
