Porous wood-based lignocellulosic material is modified by incorporating into its pore matrix a bonded silica filling. The system and method overcome the problems inherent in traditional manual injection that is characterized by poor reproducibility, human fatigue, and low throughput. Preferably locations in the interaction zone are mapped to two-dimensional display screen locations. A cholesteric liquid crystal color filter layer is at the display region and the first non-display region is on the light absorption layer. After removing methanol and CO2 from the product stream, unprocessed hydrocarbons are mixed with the hydrocarbon containing gas fro reprocessing through the reactor. Preferred embodiments of the present invention provide improved methods for TEM sample creation, especially for small geometry TEM lamellae.
