Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

An Anticoagulant Coating Based on a Block Phosphocholine Copolymer for Potential Applications in Blood Contact Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
Anticoagulant properties are critical for blood‐compatible materials, and anticoagulant coatings are a common key issue for blood‐contacting medical devices. In this study, a block copolymer poly(2‐methacrylenoxyethyl phosphocholine‐b‐glycidyl) (PMPC‐b‐GMA) is synthesized, using reversible addition‐fragmentation chain transfer polymerization (RAFT) and
