Hot-Carrier Stressing of NPN Polysilicon Emitter Bipolar Transistors Incorporating Fluorine [PDF]
, 2003 The effects of fluorine on the hot-carrier induced degradation in low-thermal-budget polysilicon emitter NPN bipolar transistors have been examined. Forward Gummel plots, base emitter (BE) diode characteristics, and stress currents were measured during ...

Direct electrophilic N-trifluoromethylthiolation of amines with trifluoromethanesulfenamide
Beilstein Journal of Organic Chemistry, 2013 The CF3SN moiety is a substituent with interesting properties. However, there is no easy synthetic access to molecules bearing this group. The trifluoromethanesulfenamide is a new reagent for the electrophilic trifluoromethylthiolation which reacts ...

Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]
, 1985 The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.

Flavin Catalysts in Organic Synthesis
Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Modulating NHC catalysis with fluorine
Beilstein Journal of Organic Chemistry, 2013 Fluorination often confers a range of advantages in modulating the conformation and reactivity of small molecule organocatalysts. By strategically introducing fluorine substituents, as part of a β-fluoroamine motif, in a triazolium pre-catalyst, it was ...

Direct Regioselective para‐Fluorination via I(I)/I(III) Catalysis
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.A direct, para‐selective fluorination by I(I)/I(III) catalysis is disclosed that does not require substrate pre‐functionalization. This strategy leverages the Leonard link inherent to phenylpropanoate and phenylpropanamides to promote a spirocyclization/para‐selective sequence. The C3‐side chain maps onto a range of common drug scaffolds and allows the
