The formation of ice due to global climate change poses challenges across multiple industries. Traditional anti-icing technologies often suffer from low efficiency, high energy consumption, and environmental pollution. Photothermal and hydrophobic surfaces with nano-micro structures (PHS-NMSs) offer innovative solutions to these challenges due to their exceptional optical absorption, heat conversion capabilities, and unique surface water hydrophobic characteristics. This paper reviews the research progress of PHS-NMSs in their anti-icing applications. It introduces the mechanisms of ice prevention, fabrication methods, and pathways for performance optimization of PHS-NMSs. The anti-icing performance of PHS-NMSs in different application scenarios is also discussed. Additionally, the paper provides insights into the challenges and future development directions in this field.

Metal complexes have long played a pivotal role in analytical chemistry due to their ability to detect and separate ions through the synergistic interaction between metal centers and ligands. This functionality can be further enhanced by integrating metal complexes non-covalently with various media, such as materials or separation platforms. Over the past four decades, the author has explored metal complex systems, including thiacalixarene-lanthanide(III) complexes, diradical platinum(II) complexes, and MOF-74, which exhibit a broad spectrum of functionalities spanning analytical applications to theranostics.

The treatment of ammonia nitrogen wastewater (ANW) has garnered significant attention due to the ecology, and even biology is under increasing threat from over discharge ANW. Conventional ANW treatment methods often encounter challenges such as complex processes, high costs and secondary pollution. Considerable progress has been made in employing solar-induced evaporators for wastewater treatment.

Activated carbon and other carbon-based materials are common photothermal materials, but their traditional production methods are energy-intensive, driving the search for low-energy alternatives. This study investigates spent coffee grounds (SCG) as a sustainable photothermal material. Rich in melanin, SCG was combined with chitosan (CS) to create a photothermal composite via hydrolysis and photo-crosslinking.

Traditional phenolic resins (PF) are extremely widely applied in industrial and daily life due to their low cost and outstanding adhesion. However, they are also limited by the toxicity of phenol and formaldehyde as well as the petroleum-based origin at the same time. Herein, a comprehensive strategy for the development of formaldehyde-free lignin-based furfural resin (LFR) with dual functions for adhesive and photothermal conversion materials was presented.
