“…Tin and lead paints peel off with time, exposing the surface underneath to microbial attacks, as in the case of ship hulls. Antimicrobial films and bacteria repellent surfaces produced by incorporating photocatalytic materials, titanium oxide, nano particle coating, carbon nanotubes, bioactive glass and other metal oxide nano particles avoid the formation of bacterial colonies [4]. However, most of these are highly toxic and their disposal is an environmental threat.…”

Micro-nano patterns created directly over solid surfaces to combat microbial activity help in preventing hospital-acquired infections. This Letter is focused on defining surface topologies by laser patterning over solid surfaces. Studies on designing surface topologies and bacterial culture have been carried out and the feasibility of micro scale features in restricting bacterial growth has been investigated. The effects of the engineered roughness index and contact angle are discussed. Contact angle measurement over patterned surfaces using a novel computer vision-based technique is demonstrated and the effect of contact angle on bacterial adhesion has been presented. The results obtained show that the designed micro scale geometries can effectively reduce the growth of bacteria on the said surfaces.

A novel sequential processing approach to fabricate versatile fibres containing encapsulated materials is presented. It is based on developing highly porous fibres, to be filled with functional materials and coated with protective layers. Applicability of the approach to develop porous poly(methyl methacrylate) (PMMA) fibres with encapsulated antibacterial salts within a coating is demonstrated. The salt was introduced to the fibre via a sacrificial solvent. Desired solvent properties to ensure successful filling was discussed. The salt was encapsulated via spray coating. The coating characteristics were tuned via vapour treatment to facilitate controllable radial salt release. Large volume axial release was also achieved due to the axial pore connectivity. Compared to state-of-the-art methods to produce fibres with functional material inclusions such as emulsion electrospinning, the method presented herein, due to its sequential processing nature, offers greater freedom in material selection and thus broad applications of the fibres.

Extract-Transform-Load (ETL) programs are used to load data into data warehouses (DWs). An ETL program must extract data from sources, apply different transformations to it, and use the DW to look up/insert the data. It is both time consuming to develop and to run an ETL program. It is, however, typically the case that the ETL program can exploit both task parallelism and data parallelism to run faster. This, on the other hand, makes the development time longer as it is complex to create a parallel ETL program. To remedy this situation, we propose efficient ways to parallelize typical ETL tasks and we implement these new constructs in an ETL framework. The constructs are easy to apply and do only require few modifications to an ETL program to parallelize it. They support both task and data parallelism and give the programmer different possibilities to choose from. An experimental evaluation shows that by using a little more CPU time, the (wall-clock) time to run an ETL program can be greatly reduced.
