Superhydrophobic surfaces can delay icing to a certain extent, but under severe conditions, such as extremely low temperatures and high humidity, ice buildup on their surfaces can still occur. Therefore, in this study, a titanium-based photothermal anti-/deicing fabric with a superhydrophobic surface was introduced, which was impregnated with hydrophobic SiO-TiO Janus particles (H-SiO-TiO JPs) and the silicone elastomer polydimethylsiloxane (PDMS) to endow it with superhydrophobic and photocatalytic properties, and then, titanium nitride nanoparticles (TiN NPs) were deposited on the surface of the cotton fabric to provide it with photothermal properties. A TiN-coated superhydrophobic cotton fabric (TiN-SCF) integrating self-cleaning, photothermal conversion, and photocatalysis was successfully prepared.

Black carbon is a paleofire proxy that has been measured from glacial ice, snow, soils and lake sediments, though relatively few comparisons have been made with other fire indicators in sedimentary geoarchives. Microscopic charcoal, quantified from palynological microscope slides and macroscopic charcoal, quantified from wet-sieved deposits, are the most commonly applied methods for paleofire interpretation of Quaternary sediments. This research explores the down-profile patterns across three paleofire proxies (refractory black carbon, microscopic and macroscopic charcoal) and potential paleofire interpretations from a sediment core dating to the last centuries from Speke Gulf, Lake Victoria, and a young soil profile from a kopje located in the surrounding watershed in Serengeti National Park, Tanzania.

Atmospheric brown carbon (BrC) from wildfires is a key component of light-absorbing carbon that significantly contributes to global radiative forcing, but its atmospheric evolution and lifetime remain poorly understood. In this study, we investigate BrC evolution by synthesizing data from one laboratory campaign and four aircraft campaigns spanning diverse spatial scales across North America. To estimate initial conditions for evaluating plume evolution, we develop a method to parametrize the emission ratios of BrC and other species using commonly measured inert tracers, acetonitrile and hydrogen cyanide.

The chemical and mechanical instability of conventional coated decorative superhydrophobic anti-icing surfaces on propeller leading edges has been a major limitation for practical applications. Here, a self-starting, uncoated, and ultra-durable superhydrophobic anti-icing surface fabricated on silicone rubber via laser-induced ceramization microstructuring is demonstrated. The laser-processed surface achieves a water contact angle of 168° and a sliding angle of 0.

Photothermal hydrophobic surfaces offer a promising solution for mitigating ice hazards under low-temperature, high-humidity conditions via solar-driven de-icing. However, surface contamination can compromise photothermal efficiency, while fabric-applicable coatings must also provide flexibility, breathability, durability, and safe thermal regulation (≈50 °C). Current systems require further optimization to balance these demands for practical use.
