Abstract: Abstract Adsorption phenomena have several technological applications such as desiccants, catalysts, and separation of gases. Their uses depend on the textural properties of the solid adsorbent and the type of the adsorbed liquid or gas.… read more here.

DOI: 10.1016/j.optlaseng.2017.07.012
Abstract: Before a contour can be laser cut the laser first needs to pierce the material. The time taken to achieve piercing should be minimised to optimise productivity. One important aspect of laser pierci ... read more here.

DOI: 10.1016/j.optlastec.2020.106221
Abstract: Abstract We analyse how the frequency bands influence the independence of speckle index values from the level of illumination in a dynamic laser speckle analysis. Specifically, we study how the temporal speckle deviation index is… read more here.
