Scanning transmission x-ray microscopy STXM

NEXAFS experiments on NOM can be conducted in several modes that differ in the type of detected particle and objectives of the experiment transmission (X rays transmitted through the sample), fluorescence (fluorescent X rays due to absorption of the X-ray beam), or electron yield (photo-emitted electron) (Sparks, 2003). Alternatively, the techniques can be divided into full-field applications such as transmission X-ray microscopy (TXM) and X-ray photoemission electron microscopy (PEEM), in comparison to scanning techniques such as scanning transmission X-ray microscopy (STXM) and scanning photoemission microscopy (SPEM) that provide spatial information of elemental forms. 

PMMA-POSS15 cyclopentyl-POSS) as compatibilizer, using scanning transmission X-ray microscopy (STXM) and scanning probe microscopy (SPM) methods was examined.

During the past few decades, much prt ess has been made in the field of microscopic techniques based on spectroscopy. One such method is scanning transmission X-ray microscopy (STXM) which permits the nondestmctive chemical mapping of heterogeneous polymers (including polymer alloys) through different specimen...
