Design of bio-inspired texturing treatments, via high power ultra-short pulse lasers, of ferritic stainless steel surfaces that inhibit the formation of bacterial biofouling on tools for hospital use and in the food industry
… which Laser-Induced Periodic Surface Structures (LIPSS) stand out. These quasi-periodic nanostructures consist of alternating ridges and valleys with a spatial period similar to or smaller than the laser wavelength used and an orientation dependent on the polarization of the laser. To generate the …

Investigating The Relationship Between Surface Topology And Functional Characteristics For Injection Moulded Thermoplastic Components
… analysed to reveal that anti-fouling LIPSS (laser induced periodic surface structures) ridges perform better to reduce bacteria cell-substrate adhesion, when compared to flat surfaces, or surfaces containing dual structures (anti-fouling ridges combined with anti-wear walls). It was …

Prebiotic photoreduction and polymerization of cysteinyl peptides.
Cysteinyl peptides likely played an important role in the prebiotic synthesis of cofactors, such as iron-sulfur clusters. However, cysteinyl peptides must be reduced in order to coordinate iron-sulfur clusters. Mixtures of ferric ions and cysteinyl peptides leads to the reduction of ferric to …

High speed mask-less laser-controlled precision micro-additive manufacture
A rapid, mask-less deposition technique for writing metal tracks has been developed. The technique was based on laser-induced chemical vapour deposition. The novelty in the technique was the usage of pulsed ultrafast lasers instead of continuous wave lasers in pyrolytic dissociation of the chemical …
