Solid-like Slippery Surface with Excellent Comprehensive Performance.

Slippery surfaces with outstanding slippery performances have shown application prospects in various fields, including anti-icing, antifouling, droplet transportation, and fog collection. However, practical application of the existing slippery surfaces is limited by lubricating oil loss, low water-slippery ability, low surface robustness, complex processes, and high costs. To overcome these limitations, we propose a facile, low-cost method to create a solid-like slippery Al surface (SSS-Al) by mixing hydrophobic nano-ceramic coating, silicone oil, and nano-SiO, which shows excellent comprehensive performance.

[Discussion on Strengthening Medical Supplies Management on Open Platform].

We introduce the background of Shanghai medical purchasing service and supervision platform (later we call it "open platform") and the effect of its implementation. We also analyze the problems occurred by medical institutions in the management of supplies, explore how to use open platform to strengthen the management of medical supplies, further optimize the structure of supplies, standardize the clinical reasonable use and charges, and ensure the quality, safety and traceability of supplies.
