By Suwas Nikumb, Peter Serles, and Evgueni Bordatchev As seen in ICALEO 2017 and LIA TODAY Nature is a bountiful source of inspiration to advance innovative surface functionalities, processes, and technologies for engineering materials. For example, the super-hydrophobic surface characteristic of the lotus leaf can be recreated by mimicking the microstructure and surface energy […]

Using UV Laser Surface Treatment to Modify the Wettability Characteristics of Polyamide 6,6 and its Effects on Osteoblast Cell Activity
By: David G. Waugh and Jonathan Lawrence Wolfson School of Mechanical and Manufacturing Engineering, Loughborough University, UK Lincoln School of Engineering, University of Lincoln, UK The need for biological implants grows year upon year and it has been realized that there is a drive within the biomedical industry for cheaper and easier to manufacture products. This […]
Surface Plasmon Polaritons for Micro and Nano-Texturing of Metal Surfaces
BY: L. Mellor, S.P. Edwardson, W. Perrie, G. Dearden, K.G. Watkins Laser Group, Department of Engineering, The University of Liverpool, Liverpool L69 3GQ, UK A study has been carried out on the production of micron and sub-micron features on the surface of a range of metallic materials through laser illumination. Possible application areas for such […]
Texturing structures of Ti films by multiple femtosecond laser pulses
By: Yongguang Huang Femtosecond laser texturing has proved to be a particularly powerful method for creating a wide variety of surface structures on the metal films, such as a hollow microbump-nanojet sturcture and disk-column-nanodroplet structure on the gold films. The process of femtosecond laser texturing does not rely on material removal, but on hydrodynamic flow […]
Ultra Short Pulse Laser Generated Surface Textures for Anti-Ice Applications in Aviation
Ultra short pulses can align nanoscale components within a complete device. Also can adjust free form mirrors by micro shockwave bending.
