Magnetic array-templated method for fabrication of polymer nanoporous films (2020)
Journal Article
Ng, J. K. G., Rybchenko, S. I., & Lukaschuk, S. (2020). Magnetic array-templated method for fabrication of polymer nanoporous films. Nano Express, 1(1), 010044. https://doi.org/10.1088/2632-959X/ab970b

This paper describes the development of a novel method of producing nanoporous polymeric membranes in a cost-effective and reproducible manner. The novelty of the technique hinges on the exploitation of a new type of sacrificial material & structures...

Non-stationary regimes of surface gravity wave turbulence (2013)
Journal Article
Bedard, R., Lukaschuk, S., & Nazarenko, S. (2013). Non-stationary regimes of surface gravity wave turbulence. JETP Letters, 97(8), 459-465. https://doi.org/10.1134/S0021364013080055

We present experimental results about rising and decaying gravity wave turbulence in a large laboratory flume. We consider the time evolution of the wave energy spectral components in ω- and k-domains and demonstrate that emerging wave turbulence can...

Gravity wave turbulence in wave tanks: Space and time statistics (2009)
Journal Article
Lukaschuk, S., Nazarenko, S., McLelland, S., & Denissenko, P. (2009). Gravity wave turbulence in wave tanks: Space and time statistics. Physical review letters, 103(4), Article ARTN 044501. https://doi.org/10.1103/PhysRevLett.103.044501

We present the first simultaneous space-time measurements for gravity wave turbulence in a large laboratory flume. We found that the slopes of k and ω wave spectra depend on wave intensity. This cannot be explained by any existing theory considering... Read More about Gravity wave turbulence in wave tanks: Space and time statistics.

Laboratory studies of near-grazing impulsive sound propagating over rough water (2008)
Journal Article
Qin, Q., Lukaschuk, S., & Attenborough, K. (2008). Laboratory studies of near-grazing impulsive sound propagating over rough water. The Journal of the Acoustical Society of America, 124(2), EL40-EL44. https://doi.org/10.1121/1.2947627

Acoustic impulses due to an electrical spark source (main acoustic energy near 15 kHz) have been measured after propagating near to the water surface in a shallow container resting on a vibrating platform. Control of the platform vibration enabled co... Read More about Laboratory studies of near-grazing impulsive sound propagating over rough water.

Surface tension: Floater clustering in a standing wave (2005)
Journal Article
Falkovich, G., Weinberg, A., Denissenko, P., & Lukaschuk, S. (2005). Surface tension: Floater clustering in a standing wave. Nature, 435(7045), 1045-1046. https://doi.org/10.1038/4351045a

How do waves affect the distribution of small particles that float on water? Here we show that drifting small particles concentrate in either the nodes or antinodes of a standing wave, depending on whether they are hydrophilic or hydrophobic, as a re...
