Analytical characteristics of a multilayer dispersion element (2d = 60 A) in the determination of fluorine in minerals by electron microprobe

The analytical characteristics of a W/Si multilayer dispersion element (MLDE) with a nominal 2d spacing of 60,~ are assessed and compared with those of a conventional thallium acid phthalate (TAP) crystal for the determination of fluorine in silicate and phosphate minerals by electron microprobe. Measured count rates for fluorine were found to be up to fourteen times higher using the MLDE compa...

Introduction of fluorine and fluorine-containing functional groups.

Over the past decade, the most significant, conceptual advances in the field of fluorination were enabled most prominently by organo- and transition-metal catalysis. The most challenging transformation remains the formation of the parent C-F bond, primarily as a consequence of the high hydration energy of fluoride, strong metal-fluorine bonds, and highly polarized bonds to fluorine. Most fluori...

Organo - Fluorine Chemical Science Inventing the Fluorine Future 2012 Helmut

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...
