Distearoylphosphatidylcholines labeled with gem-difluoro groups at selected positions of the fatty acid chains have been prepared. These lipids were incorporated into sonicated vesicles and were examined by fluorine nuclear magnetic resonance spectroscopy. All spectra are characterized by two well-separated fluorine resonances. Paramagnetic ions added to the exterior solution of vesicles of flu...

We investigated the chlorine plasma reaction with graphene and graphene nanoribbons and compared it with the hydrogen and fluorine plasma reactions. Unlike the rapid destruction of graphene by hydrogen and fluorine plasmas, much slower reaction kinetics between the chlorine plasma and graphene were observed, allowing for controlled chlorination. Electrical measurements on graphene sheets, graph...

We demonstrate the possibility to tune the electronic transport properties of graphene mono-layers and multi-layers by functionalisation with fluorine. For mono-layer samples, with increasing the fluorine content, we observe a transition from electronic transport through Mott variable range hopping (VRH) in two dimensions to Efros-Shklovskii VRH. Multi-layer fluorinated graphene with high conce...

New synthetic methods and fluorinated reagents have been developed,that facilitate the introduction of fluorine or fluorocontaining units into small building blocks, designer compounds, and materials of new and often surprising properties. However,in spite of all these advances, we are still lacking sufficient insight into the fundamental aspects of fluoro-organic chemistry,particularly in the ...

An omega-fluorine-labeled oxyethylene thiol ligand, F(CH2CH2O)2CH2CH2SH, was synthesized, characterized and incorporated into mixed self-assembled monolayers with CH3(OCH2CH2)3SH onto a planar gold substrate and onto 2 nm gold nanoclusters. The fluorine-labeled nanocluster was self-assembled onto gold substrates using alkane dithiol (HS(CH2)nSH; n = 5, 8, 11) and oxyethylene dithiol (HS(CH2CH2O...

A comprehensive study is made of the behavior and effects of fluorine in n-polysilicon layers. The polysilicon is deposited in a conventional low pressure chemical vapor deposition furnace on ~100! silicon wafers, implanted with 1310 cm F and 1310 cm As and annealed at 850, 950, 1015, and 1065 °C. Sheet resistance, transmission electron microscopy ~TEM!, and secondary ion mass spectroscopy are ...

Intensive investigations during the last years have shown that metabotropic glutamate receptors are involved in numerous neurodegenerative diseases such as M. Parkinson, M. Alzheimer and M. Huntington as well as other central nervous system disorders including neurogenic pain, epilepsy, depression and drug addiction. The neurobiological basis of these impairments is, however, still not well und...

The generated resist based defects on the template in addition to the presence of particles and contaminants is critical for ultraviolet curing of nanoimprint lithographic fabrication. This procedure is proven to be suitable for advanced resist material design under the process conditions. Nanoimprint resist material containing an ultraviolet reactive fluorine surfactant was developed to modify...
