The high-quality aspects of magnified X-ray images recorded using MIRRORCLE-6X are reported. MIRRORCLE-6X is inherently suitable for hard X-ray imaging owing to its magnified projection X-ray imaging, micrometre-size X-ray source point, wide radiation emission angle, X-ray spectrum ranging from 10 keV to 6 MeV, natural refraction contrast imaging and high flux output. Images produced with 11x geometrical magnification display a sharply enhanced edge effect when generated using a 25 microm rod electron target. Image contrast is enhanced 2x owing to refraction when compared with absorption contrast images. An imitation tumour implanted in a human chest phantom was made clearly visible by using edge enhancement on images. Soft tissue becomes highly visible as a natural consequence of refraction contrast when using hard X-rays for imaging. The authors believe that novel imaging provided by MIRRORCLE makes it a superior instrument for medical diagnosis.
The IH NMR spectra of guest molecules. n-paraffins (n-C,H,, , n-C6Hl, , n-c.,H16, n-GHzo, and n-C,H,), were measured in poly(y-benzyl-L-glutamate) liquid crystalline solution. The methylene signal of n-paraffins is a doublet due to magnetic dipole-dipole interaction. These results suggest that an n-paraffin takes predominantly the extended form in the restricted molecular motion state and that its long axis orients in the same direction as the helical axis of poly(y-benzyl-L-glutamate) parallel to the magnetic field. The results are compared with the molecular motion and conformation of n-paraffins in a-chloronaphthalene.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
