Methods Wild type human von Willebrand factor cDNA: Von Willebrand factor cDNA was cloned from the Marathon-ready human bone marrow cDNA library (Clontech, Mountain View, CA) using the following three sets of primers: 5'-CCATCCTAATACGACTCACTATAGGGC-3’ / 5'TCAATCTCTCCTCCCTCCACCAGGAT-3' (VWF 3-3103), 5'CTCACCTTCGACGGGCTCAAATACCTG-3' / 5'-TGGGAGCTGTCGGGGACAAGACAC-3' (VWF 2925-6712), 5'-AGCGAATCGAA...

Terahertz metasurfaces with pixelated meta-atoms were designed for linear-polarization conversion and absorption. The differences between the two functionalities emerged from number arrangement of metal-dielectric combos patching some but not necessarily every pixel each meta-atom. A a meta-atom 3×3 pixels yielded polarization ratio (PCR) >0.9 over 10.20–16.08 THz band, whereas another absorpta...
