Anti-icing properties of femtosecond laser-induced nano and multiscale topographies

چکیده

Abstract Surfaces covered with micro, nano and multiscale topographies are the subject of significant interest due to their ice-repellency properties in last decade. Ultrafast laser processing is becoming a widely used clean manufacturing technique fabricate ordered on metallic surfaces over relatively large areas. In this work, single-tier two-tier were fabricated stainless steel one-step femtosecond impart anti-icing response. Droplet freezing frost formation treated examined at −10 °C compared lubricant-impregnated superhydrophobic nanoparticle-coated ones. While hydrophilic nanoscale topography has accelerated droplet performed worse than untreated surfaces, hydrophobic counterparts increased time by nearly two times. Overall, significantly delayed both surfaces. Furthermore, sustained its response even after being subjected 25 abrasion cycles, while only nanoparticle-coating lost functionality 10 cycles. Therefore, such robust devoid any coatings can enable underpin many industrial applications where ice accumulation results performance degradation, e.g. aerospace, refrigeration, air-conditioning energy applications.

Toward nano- and microprocessing in glass with femtosecond laser pulses

In this paper, we report on the refractive index changes and vacancies that are induced in silica glass by the irradiation of ultrashort laser pulses. We fabricated waveguides, couplers, and gratings by the filamentation of femtosecond laser pulses. We demonstrate the formation and the movement of sub-micrometer or nanometer vacancies, called voids. We show the formation of three-dimensional sh...

Biocidal properties of anti-icing additives for aircraft fuels.

The biocidal and biostatic activities of seven glycol monoalkyl ether compounds were evaluated as part of an effort to find an improved anti-icing additive for jet aircraft fuel. Typical fuel contaminants, Cladosporium resinae, Gliomastix sp., Candida sp., Pseudomonas aeruginosa, and a mixed culture containing sulfate-reducing bacteria were used as assay organisms. Studies were carried out over...
