Characterization of the complete chloroplast genome of Wisteriopsis reticulata (Fabaceae): an IRLC legumes.

The inverted repeat-lacking clade (IRLC) species are characterized by the loss of an IR region in their plastomes, which has long been of great interest. Wisteriopsis reticulata is one of the members of the tribe Wisterieae, which belongs to Fabaceae and is well-known as IRLC. Here, we reported and characterized the complete chloroplast genome of W. reticulata using the genome skimming approach. The chloroplast genome is 132,477 bp in length and lacks one copy of IR region. The genome encoded 112 unique genes including 89 protein-coding genes, 29 transfer RNA genes and four ribosomal RNA genes. Phylogenetic results supported the monophyly of the tribe Wisterieae (IRLC) and confirmed that W. reticulata belongs to the genus Wisteriopsis.

Facilely Fabricated Self-Lubricated Photothermal Coating with Long-Term Durability and External-Replenishing Property for Anti-Icing/Deicing.

Icing has a severe negative impact on daily life and equipment stability. The slippery liquid-infused porous surface (SLIPS) has been widely studied for icephobicity. However, loss of lubrication leads to the failure of icephobicity. In this work, a self-lubricating photothermal surface (SLPS) based on multiwalled carbon nanotubes (MWNTs) and silicone oil was fabricated by a facile preparation method to realize passive anti-icing/deicing and active deicing simultaneously. SLPS can inhibit frost formation, delay freezing, and reduce ice adhesion strength (τice) under low-light and dark conditions. The τice value of SLPS-5-2 was 5.82 kPa in the absence of light at -20 °C. MWNTs improve the oil locking ability and inhibit oil loss, enhancing durability. The τice value of SLPS-5-2 remained within 20 kPa during 30 icing cycles. Meanwhile, SLPS has the excellent external replenishment capability to recover icephobicity. In addition, SLPS shows excellent photothermal deicing performance to melt frost, droplets, and ice layer quickly. Icing can be removed fast due to the oil layer. Silicone oil enhances the lateral heat transfer, improving the photothermal deicing. This all-in-one integration of the self-lubricating and photothermal effect finally boosts icephobicity compared to the traditional SLIPS or individual photothermal materials toward environmentally compatible and solar-driven icephobicity.
