Developing a novel antibacterial coating system for marine corrosion and fouling control.

Microbial-influenced corrosion and marine biofouling have become a thorny problem restricting the effective long-term operation of marine engineering. In this study, a novel antibacterial coating system for marine corrosion and fouling control was developed to integrate and improve the antibacterial performance. The coating system was composed of an epoxy primer and a low surface energy organosilicon/polyurethane topcoat, while quaternary ammonium salt (QAS) was added as an antimicrobial agent.

Dual Stimulus Responsive GO-Modified Tb-MOF toward a Smart Coating for Corrosion Detection.

Smart-sensing coatings that exhibit multistimulus response, rapid indication, and reusability are in urgent need to effectively enhance the practicability of coatings while accurately detecting metal corrosion. In this work, a reusable corrosion self-reporting coating with multiple pH and Fe stimulus responses was first constructed by the integration of a composite fluorescent probe into the resin matrix. This composite sensor was constructed by combining a lanthanide metal-organic framework (Ln-MOF) based on terbium and trimeric acid (HBTC) with graphene oxide (GO) nanosheets (GO@Tb-BTC).

Phase separation of S-RNase promotes self-incompatibility in Petunia hybrida.

Self-incompatibility (SI) is an intraspecific reproductive barrier widely present in angiosperms. The SI system with the broadest occurrence in angiosperms is based on an S-RNase linked to a cluster of multiple S-locus F-box (SLF) genes found in the Solanaceae, Plantaginaceae, Rosaceae, and Rutaceae. Recent studies reveal that non-self S-RNase is degraded by the Skip Cullin F-box (SCF)-mediated ubiquitin-proteasome system in a collaborative manner in Petunia, but how self-RNase functions largely remains mysterious.

SnF -Catalyzed Formation of Polymerized Dioxolane as Solid Electrolyte and its Thermal Decomposition Behavior.

Polymerized-dioxolane(P-DOL) is of potential as a solid-polymer-electrolyte(SPE) due to its high Li -conductivity, good compatibility with Li-metal and desired preparation method of in situ polymerization in cells. In this study, SnF was demonstrated not only to be an efficient catalyst for the polymerization of DOL at room temperature, but also an effective additive for improving interfacial wettability and suppressing dendrite through the reaction with Li-metal and the formation of LiF/Li Sn based composite solid electrolyte interlayer(SEI). Using the SnF polymerized P-DOL containing 1 M LiTFSI as SPE(P-DOL-SPE), obviously denser Li-deposition was obtained, and the all-solid-state(ASS) Li/LiFePO cell delivered stable cycling over 350 cycles at 45 °C.
