Stefan Oelmann et al.
Biomacromolecules, 20(1), 90-101 (2018-06-06)
A Passerini three-component polymerization was performed for the synthesis of amphiphilic star-shaped block copolymers with hydrophobic cores and hydrophilic coronae. The degree of polymerization of the hydrophobic core was varied from 5 to 10 repeating units, and the side chain
Thallium in organic synthesis. 43. Novel oxidative rearrangements with thallium (III) nitrate (TTN) in trimethyl orthoformate (TMOF).
Taylor EC, et al.
Journal of the American Chemical Society, 98(10), 3037-3038 (1976)
Synthesis of 8-demethyl-8-hydroxy-5-deazariboflavins
Ashton WT and Brown RD

P F Holmes et al.
Journal of biomedical materials research. Part A, 91(3), 824-833 (2008-12-04)
The synthesis of surface-modified silica nanoparticles, chemically grafted with acrylate and poly(ethylene glycol) (PEG) groups, and the ability of the resulting crosslinked coatings to inhibit protein adsorption and bacterial adhesion are explored. Water contact angles, nanoindentation, and atomic force microscopy

EJNMMI physics, 7(1), 22-22 (2020-04-24)
For multicenter clinical studies, PET/CT and SPECT/CT scanners need to be validated to ensure comparability between various scanner types and brands. This validation is usually performed using hollow phantoms filled with radioactive liquids. In recent years, 3D printing technology has
