Development of UVB LED Lighting System Based on UV Dose Calculation Algorithm to Meet Individual Daily UV Dose

UV LED lighting for automated crystal centring

A direct outcome of the exponential growth of macromolecular crystallography is the continuously increasing demand for synchrotron beam time, both from academic and industrial users. As more and more projects entail screening a profusion of sample crystals, fully automated procedures at every level of the experiments are being implemented at all synchrotron facilities. One of the major obstacle...

UV Index and UV dose distributions for Australia ( 1997 - 2001 )

Calculating UV Dose for UV/AOP Reactors Using Dose/Log as a Water-Quality Metric

A method for scale up of UV/AOP reactors is outlined that uses bench scale testing to determine the UV dose required per log destruction (DL) of a particular contaminant. This can then be used in CFD Modeling to size a full-scale UV reactor and to test the reactor in performance trials. Methods for calculating dose based on the path length distribution in a UV reactor are given.

Bioassay and dose measurement in UV disinfection.

A bioassay method was developed to measure the average intensity within a UV disinfection reactor. The survival of spores of Bacillus subtilis was determined as a function of UV dose to prepare a standard curve. Spores were added to unknown systems, and the survival rate was used to determine the average intensity. A modification was used for flow-through reactors by which spores were injected ...

UV-LED photopolymerised monoliths.

For the first time photopolymerisation of polymer monoliths has been realised with UV-light emitting diodes (LEDs) as light source and demonstrated with polymethacrylate monoliths created in fused silica capillaries and plastic chips.
