In the present work, high-thickness zwitterionic polymer brushes based on imidazolium salts were successfully grafted via a novel subsurface-initiated ringopening metathesis polymerization (subsurface-initiated ROMP) from polydimethylsiloxane (PDMS), and their antifouling performance was evaluated in detail. First, an initiator-embedded PDMS was prepared via copolymerization of PDMS prepolymer and ROMP initiator, and then zwitterionic polymer brushes were grafted via subsurfaceinitiated ROMP from surface to subsurface of the PDMS due to the implanted ROMP initiator. Results from a series of characterization methods such as infrared spectroscopy, X-ray photoelectron spectroscopy, contact angle, and atomic force microscopy proved the zwitterionic polymer brushes' successful grafting. The grafting thickness of zwitterionic polymer brushes via subsurface-initiated ROMP can reach the micron scale, and the as-prepared zwitterionic polymer based surfaces showed good lubricating properties compared to traditional surfaceinitiated ROMP, which hints that polymer brushes can be grafted not only on the surface but also on the subsurface of PDMS. The protein adhesion test and biofouling assay of zwitterionic polymer brushes were tested in the laboratory, and the results indicated that the zwitterionic polymer-functionalized PDMS can effectively resist the adhesion of bovine serum albumin and algae (Porphyridium and Dunaliella) and has good anti-bacterial activity against both Escherichia coli and Staphylococcus aureus.

Multifunctional intelligent theranostics agents are promising for next-generation oncotherapy. We fabricated a tumor-microenvironment (TME)-responsive carbon nanotubes (CNTs)-based nanoplatform with T1 weighted magnetic resonance imaging (MRI)-guided synergistic photodynamic and photothermal therapy...

Organizations recently attach growing importance to sustainable development and green human resource management (GHRM), raising research interest in predicting employee green behavior (EGB). However, the potential linkage between a sense of calling and EGB is neglected. This research fills the void by examining whether, how, and when calling predicts EGB. Drawing upon self‐determination theory, we argue that by satisfying three basic psychological needs (i.e., autonomy, competence, and relatedness), a sense of calling enhances employees' prosocial motivation, which in turn promotes EGB. We further propose that calling predicts EGB more effectively for less conscientious employees. We conducted two field surveys to test the hypotheses. Both Study 1 (N = 280) and Study 2 (N = 295) confirm that calling positively affects EGB through partial mediation of prosocial motivation and that conscientiousness negatively moderates the relationship between calling and prosocial motivation as well as the indirect effect. Theoretical contributions and practical implications are discussed.
