an essential requirement for an operating pem fuel cell is providing proper water content in the membrane. to avoid water flooding an appropriate water balance is required. here, an analytic model of a planar membrane humidifier for pem fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. a n...

Abstract Scientific publications and newsfeeds recently focused on flushable wet wipes their role in sewage system blockages. It is stated that although products are marked as flushable, they do not disintegrate after being disposed of via the toilet. In this work it shown wetlaid hydroentangled lose initially good dispersive properties during storage condition. As a consequence, we suggesting ...

Abstract Designing a feasible in vitro enzyme cascade is challenging task that often preceded by optimization steps. Computational methods can increase the efficiency of process providing deeper insight into system. In this study, bottlenecks farnesyl pyrophosphate‐producing were determined combination silico modeling and wet‐lab experiments. ATP precursor‐isomerizing isopentenyl diphosphate δ ...

graduate school to study biology. At first, it was as if I was starting over, taking classes I had bypassed as an undergraduate, such as Introductory Organic Chemistry. But my motivation to master a new field made the experience enjoyable rather than frustrating. Moreover, I was captivated by the science. In my biology classes, I felt I was being offered gold nuggets of information that earlier...
