Vm–MSI: a Vancomycin–Antimicrobial Peptide Conjugate Combating Resistant Bacteria and Broadening the Antimicrobial Spectrum

open access: yesAdvanced Science, EarlyView.
A series of vancomycin‐antimicrobial peptide conjugates is synthesized and evaluated to identify the optimal combination. Vm‐MSI, selected from multiple candidates, exhibited potent activity against vancomycin‐resistant and Gram‐negative bacteria by disrupting membranes and inducing oxidative stress, thereby expanding vancomycin's antibacterial ...

Encapsulating Textiles with Dynamic Covalent Networks for Sustainable and Efficient Oil Spill Cleanup

open access: yesAdvanced Science, EarlyView.
By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...

Novel Phosphazenium Tetrafluoroborate Dopant Enables Efficient and Thermally Stable n‐Doped Organic Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on
