Promising nanotechnology-enabled sensors, monitoring devices and analytical instruments continue to advance toward commercialization for diverse industrial, environmental, medical and military applications— but hurdles remain.
Use Exponential Functions to Correlate Temperature Dependence Asymptotic exponential equations may provide a more-accurate or easier-to-use representation of a property’s temperature dependence than commonly used polynomial expressions.
Dynamic process modeling based on non-uniformly sampled data and multiple sampling runs, even for nonlinear systems, can be performed using spreadsheet implementations of the weighted-least-squares (WLSQ) and Runge-Kutta WLSQ methods.
Issues such as sterility, isolation and contamination must be considered when choosing seals for use in biotech and pharmaceutical processes. This overview describes common types of seals and offers guidance on selecting the appropriate seal for...
Understanding when and why mixing fails in the laboratory is often the only way of avoiding a similar failure in a production-scale reactor. Here we examine mixing in stirred-tank reactors and provide guidance on scale-up.
