Spatial chromatography
-
Spatial comprehensive two-dimensional liquid chromatography (xLC×xLC) may be an efficient approach to achieve high peak capacities in relatively short analysis times, thanks to parallel second-dimension separations.

Conventional one-dimensional column-based liquid chromatographic (LC) systems do not offer sufficient separation power for the analysis of complex mixtures. Column-based comprehensive two-dimensional liquid chromatography offers a higher separation power, yet suffers from instrumental complexity and long analysis times.

Although our knowledge about diatom photosynthesis has made huge progress over the last years, many aspects about their photosynthetic apparatus are still enigmatic. According to published data, the spatial organization as well as the biochemical composition of diatom thylakoid membranes is significantly different from that of higher plants.

The distribution of fifteen polycyclic aromatic hydrocarbons (PAHs) indicated from USEPA as priority pollutants was studied in surface sediments (0 - 20 cm) of coastal wetland area of Can Gio district, Hochiminh City. PAHs were recovered from the sediments by solvent extraction and then analyzed by means of high performance liquid chromatography system. Total concentrations of the ∑PAHs in the range 5 – 38 ng/g dw were detected, and a distinct spatial trend was observed.

This book is unique because it concentrates on work designed and built by emerging and newly defined practices that, with a do-it-yourself attitude, regularly pioneer techniques and experiment with fabrication processes on a small scale. The means by which these projects were realized are within the reach of many practitioners and students. Here, the architectural project is a form of applied design research. These architects seek to leverage digital design and manufacturing for perceptual, spatial, and formal effect.
