Characterisation of PMMA microfluidic channels and devices fabricated by hot embossing and sealed by direct bonding
In this study we fabricated a silicon-based stamp with various microchannel arrays, and demonstrated successful replication of the stamp microstructure on poly methyl methacrylate (PMMA) substrates. We used maskless UV lithography for the production of the micro-structured stamp. Thermal imprint lithography was used to fabricate microfeatured fluidic platforms on PMMA substrates, as well as to ...
متن کاملCotreatment of sewage and septage in waste stabilization ponds.
A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge. The monitoring program was divided in two phases. The results of the first...
متن کاملSeptage treatments to reduce the numbers of bacteria and polioviruses.
Disposal of the pumped contents of septic tanks (septage) represents a possible means of dissemination of enteric pathogens including viruses, since persistence of enteroviruses in septic tank sludge for greater than 100 days has been demonstrated. The risk of exposure to potentially infectious agents can be reduced by disinfecting septages before their disposal. Of the septage disinfectants ex...
متن کاملModelling Sealed Containers in Z
Physical means of securing information, such as sealed envelopes and scratch cards, can be used to achieve cryptographic objectives, including ones that are hard or impossible by electronic means. So far, descriptions of such mechanisms have been informal, and as a consequence so has the associated reasoning. This paper3 takes a formal methods approach to these physical cryptography primitives....
