Sensors, Vol. 17, Pages 755: The Combination of Micro Diaphragm Pumps and Flow Sensors for Single Stroke Based Liquid Flow Control

03-Apr-2017 | Jenke, Christoph ; Pallejà Rubio, Jaume ; Kibler, Sebastian ; Häfner, Johannes ; Richter, Martin ; Kutter, Christoph, Sensors, 2017

With the combination of micropumps and flow sensors, highly accurate and secure closed-loop controlled micro dosing systems for liquids are possible. Implementing a single stroke based control mode with piezoelectrically driven micro diaphragm pumps can provide a solution for dosing of volumes ...

How Does Predation Affect the Bioaccumulation of Hydrophobic Organic Compounds in Aquatic Organisms?

31-Mar-2015 | Xinghui Xia; Husheng Li; Zhifeng Yang; Xiaotian Zhang; Haotian Wang, Environmental Science & Technology, 2015

It is well-known that the body burden of hydrophobic organic compounds (HOCs) increases with the trophic level of aquatic organisms. However, the mechanism of HOC biomagnification is not fully understood. To fill this gap, this study investigated the effect of predation on the bioaccumulation of ...

Development of a Partition-Controlled Dosing System for Cell Assays

15-Nov-2010 | Nynke I. Kramer; Frans J. M. Busser; Mattheus T. T. Oosterwijk; Kristin Schirmer; Beate I. Escher; Joop L. M. Hermens, Chemical Research in Toxicology, 2010

Hydrophobic and volatile chemicals have proven to be difficult to dose in cell assays. Cosolvents are often needed to dissolve these chemicals in cell culture medium. Moreover, the free concentration of these chemicals in culture medium may diminish over time due to metabolism, evaporation, and ...
