We review our recent work on the deterministic (top down) micro/nano structuring and stochastic (random) micro/nano texturing of polymeric materials for a variety of applications. We create polymeric microfludics/microsystems using plasma processing as well as 'smart' polymer surfaces with controlled wetting and optical properties. First, fabrication of polymeric micro-nanosystems and microfluidics using standard photolithography followed by plasma etching is proposed as an alternative method for polymer microfabrication. Second, plasma induced polymer nanoroughening (nanotexturing) is proposed as an extremely attractive methodology to control the wetting properties of polymers and create superhydrophilic or hydrophobic or robust superhydrophobic polymer surfaces. These surfaces may in addition possess controlled optical properties, such as antireflectance combined with good transmittance. Third, ordered spontaneously formed structures are created on plasma processed polymers. Potential applications are discussed.

Development of a Cleaning Validation Method for MICRO® A07 Citric Acid Cleaner Using HPLC-CAD
AbstractA high performance liquid chromatography (HPLC) method with a Corona Charged Aerosol detector for the cleaning validation of MICRO* A07 Citric Acid Cleaner residue has been developed. The pooled average repeatability of 3 replicates at 6 concentration levels expressed as RSD was 1.3 % while the pooled average intermediate precision (intra-day repeatability in 3 days) of 3 replicates at 6 concentration levels was 2.4 %. Simulated maximum allowable carryover (MAC) was calculated by using 10 ppm of MICRO®...
Steel Fire Sprinkler Tank Inspection Case Study
These images show the steel fire sprinkler tank before any preparation work and then after preparation. The steel fire sprinkler tank was fully relined with Acothane DW. A Logistics company in Berkshire recently had an R.O.V Inspection carried out on their Fire Tank, we also provided them a sprinkler tank maintenance. The sprinkler tank inspections confirmed significant amounts of corrosion to numerous areas of the internal substrate. The overall size of the fire sprinkler tank is approximately 9.2m diameter x...

The challenge of safety and health in micro and small enterprises: what can be done?
A high-level policy seminar, ‘Micro and small enterprises (MSEs) in Europe: How can we make sure they are safe, healthy and productive places to work?’, was organised by EU-OSHA in Brussels in June, with representatives from the European Parliament and the European Commission, social partners and other key actors and academic experts. Discussions focused on how to ensure the health, safety and well-being of the millions of European citizens who work in MSEs, as well as the role of MSEs in the...
