Damaged surfaces self-replenish their chemical composition by the spontaneous re-orientation of functional groups chemically bonded to the polymer network. The repair of the surface chemistry leads to the recovery of surface functionality. This self-replenishing approach is suitable to recover many surface-related properties and constitutes a major breakthrough in extending the service life-time of functional materials.

As a global challenge, marine biofouling is causing serious economic losses and adverse ecological impacts. In recent years, a variety of promising and environmentally friendly anti-fouling strategies have emerged, among which the excellent anti-fouling performance of bionic autocrine coatings has been recognized. However, bionic autocrine coatings still suffer from uncontrollable secretion behavior, poor mechanical stability, and poor abrasion resistance.

We have developed a new scanning probe approach for the delivery of a gas-phase reactant to the surface of an electrocatalyst through a self-replenishing bubble located at the end of a scanning probe. This approach enables local electrocatalytic rates to be detected under very-high mass transport rates due to the small distance between the gas-phase reactant in the bubble and the electrocatalyst surface. Here we report experiments for the delivery of carbon dioxide to a gold ultramicroelectrode surface using a micron-scale nanopipette.

Article Synopsis
- The study addresses the challenges of using nanozymes for cancer therapy due to limited substrates like HO and O in the tumor microenvironment (TME).
- Researchers developed a novel MnO@PtAuRu nanoreactor that combines a hollow MnO core with tiny PtAuRu nanoclusters to enable self-propelling and cascading catalytic reactions for better tumor treatment.
- The nanoreactor not only produces hydroxyl radicals for enhanced chemodynamic therapy but also protects the nanoclusters during circulation and interacts with tumor-specific elements, making it a promising strategy for effective cancer therapy.

Slippery liquid-infused porous surfaces (SLIPSs) inspired by have attracted much attention owing to their potential application in various cutting-edge fields. However, the performance of SLIPSs is impeded by surface damage and lubricant depletion, thereby limiting their further application. Herein, a UV-responsive slippery surface (SMEMG) was fabricated by introducing the UV-responsive functional group coumarin into the polymer side chain through random copolymerization, followed by crosslinking, curing and impregnation with vegetable oil.

Titanium dioxide (TiO), by its tribological behavior, is known as a solid lubricant. TiO as a solid lubricant, together with tungsten disulfide (WS) and molybdenum disulfide (MoS) decreases friction and excessive wear. By compacting TiO powder, pellets are formed.
