Flow Of Dna Solutions In A Microfluidic Gradual Contraction, Shelly Gulati, Susan J. Muller, Dorian Liepmann Jan 2015

Flow Of Dna Solutions In A Microfluidic Gradual Contraction, Shelly Gulati, Susan J. Muller, Dorian Liepmann

Shelly Gulati

The flow of λ-DNA solutions in a gradual micro-contraction was investigated using direct measurement techniques. The effects on DNA transport in microscale flows are significant because the flow behavior is influenced by macromolecular conformations, both viscous and elastic forces dominate inertial forces at this length scale, and the fully extended length of the molecule approaches the characteristic channel length wc (L/wc ∼ 0.13). This study examines the flow of semi-dilute and entangled DNA solutions in a gradual planar micro-contraction for low Reynolds numbers (3.7 × 10−6 < Re < 3.1 × 10−1) and high Weissenberg numbers (0.4 < Wi < …

Peat And Coconut Fiber As Biofilters For Chromium Adsorption From Contaminated Wastewaters, Henryk Koloczek, Jaroslaw Chwastowski, Witold Zukowski Dec 2014

Peat And Coconut Fiber As Biofilters For Chromium Adsorption From Contaminated Wastewaters, Henryk Koloczek, Jaroslaw Chwastowski, Witold Zukowski

Witold Zukowski

Batch adsorption experiments were performed for the removal of chromium (III) and chromium (VI) ions from aqueous solutions using Canadian peat and coconut fiber. The Langmuir model was used to describe the adsorption isotherm. The maximum adsorption for peat reached 18.75 mg/g for Cr(III) and 8.02 mg/g for Cr(VI), whereas the value for fiber was slightly higher and reached 19.21 mg/g for Cr(III) and 9.54 mg/g for Cr(VI). Both chromium forms could be easily eluted from the materials. The adsorption of chromium forms to organic matter could be explained in terms of formation of donor-acceptor chemical covalent bound with hydroxyl …
