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 selflubricating 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 (τ ice ) under lowlight and dark conditions. The τ ice 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 τ ice 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.
In recent years, the fabrication of hydrophobic materials and their excellent applications in oil spill cleanup has attracted widespread attention. Herein, we report the rapid and straightforward preparation of ZnCo 2 O 4 nickel foam by hydrothermal synthesis. The prepared sample surfaces possess excellent superlipophilicity and superhydrophobicity after modification by stearic acid, so it can efficiently absorb light and heavy oil in water, and the absorption efficiency is over 99%. Besides, the unmodified ZnCo 2 O 4 nickel foam could be subjected to effective oil-water separation at standard temperature and pressure, and its separation efficiency can be more than 97.4%. After 20 continuous filtration cycles, it can maintain stable high separation efficiency and even work under harsh environmental conditions, like acid, alkali, salt solution, high and low temperature, and ultraviolet radiation. Compared with other methods of manufacturing hydrophobic materials, this method is facile, lower cost, environmentally durable, and highly efficient. Therefore, the as-prepared ZnCo 2 O 4 nickel foam has good application value in treating oily wastewater.
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
