Article Synopsis
- Researchers have developed a new type of supported organic nanofabric using small-molecule organic nanowires and nanotrees, created through a combination of vacuum and plasma techniques.
- These nanofabrics can be formed at low temperatures on various substrates, resulting in flexible three-dimensional structures with unique wetting and anti-icing properties.
- The nanofabric exhibits high water contact angles over 150° and can delay freezing for over 2 hours at -5 °C, making it suitable for applications like slippery liquid-infused porous surfaces (SLIPS).
Article Synopsis
- * A new method using ultrathin plasma polymer encapsulation at room temperature enhances stability against water and moisture without compromising performance.
- * Encapsulated solar cells show minimal absorbance change even after 30 days in humid conditions and maintain performance when immersed in water, suggesting a significant step toward reliable solar energy technology.
We present a low-temperature versatile protocol for the fabrication of plasma nanocomposite thin films to act as tunable emitters and optical gain media. The films are obtained by the remote plasma-assisted deposition of a 4-(dicyano-methylene)-2-methyl-6-(4-dimethylamino-styryl)-4H-pyran (DCM) laser dye alongside adamantane. The experimental parameters that determine the concentration of the dye in the films and their optical properties, including light absorption, the refractive index, and luminescence, are evaluated.

The methodology is based in the formation of parallel micrometric crack patterns when polydimethylsiloxane foils coated with tilted nanocolumnar SiO2 thin films are manually bent. The SiO2 thin films are grown by glancing angle deposition at room temperature.
