A simple nanoimprinting method creates arrays of ferroelectric polymer structures suitable for low-cost, non-volatile memories. With the development of nanoimprinted high-quality ferroelectric nanomesa arrays, it seems that we now have all the necessary ingredients to print inexpensive, disposable organic memory chips. Figure 1. The nanoimprinting method and the two ways it can be used in non-v...

The term 'ultrapure water' is a common way to define water used for on-line treatments: it refers to the absence of chemical, organic and microbiological contamination. To be more accurate in definition, every known and potential contaminant has to be fixed at its limit value. AAMI recommendations and various Pharmacopoeias have set limits for dialysate based on traditional dialysis treatments,...

This paper presents an interesting contrast between foggy and hazy periods of various AMS variables indicating degree of OA oxidation or volatility. The results are likely to be of particular interest to the AMS community, but some of the findings are also of general interest to those investigating secondary organic aerosol formation. Although the data is interesting, in my view the author’s wa...

The U.S. FDA [1] process validation guidance document released in 2011 increased the emphasis on continued process verification: “ongoing assurance is gained during routine production that the process remains in a state of control”. Until recently, in a washing system, conductivity analysis was the only on-line method used to monitor the quality of the final rinse water. Now, developments in th...
