Detection and Manipulation of Interaction Between Magnetic DyPc2 Molecules and Superconducting Pb(111) Surface

open access: yesAdvanced Materials Interfaces, EarlyView.
The research focuses on the interaction between the magnetic DyPc2 molecules and the superconducting Pb(111) surface. A complex quantum spin system is observed in both DyPc2 molecules embedded in the self‐assembled monolayer and those scattered atop it, where Kondo screening and superconducting pairing coexist and compete.

IR Spectroscopic Studies on Water Confined in an Isoreticular MOF Series–Influence of the Metal and Linker Functionality

open access: yesAdvanced Materials Interfaces, EarlyView.
Mono‐ and bimetallic isoreticular MOF‐74 analogs with different ratios of Mg2+ and Ni2+ and linkers of different sizes and functionalities are synthesized and loaded with water. With the help of IR spectroscopy, semiquantitative conclusions are drawn regarding the prevalence of differently ordered water species in dependence on the confinement and ...

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.

Aqueous Synthesis of Poly(ethylene glycol)‐Amide‐Norbornene‐Carboxylate for Modular Hydrogel Crosslinking

open access: yesAdvanced Materials Interfaces, EarlyView.
An all aqueous synthesis of poly(ethylene glycol)‐amide‐norbornene‐carboxylate (PEGaNBCA) is developed via reacting carbic anhydride with amino‐terminated PEG. PEGaNBCA is readily crosslinked into hydrogels by click chemistries. PEGaNBCA crosslinked thiol‐norbornene hydrogels are hydrolytically stable but can be rendered hydrolytically labile through ...

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
