Besides the disadvantageous space-time yield, the risks of cross-contaminations and product loss grow fast with the complexity of the isolation procedure. A significant reduction of unit operations can be achieved by application of magnetic particles, especially if these are functionalized with affinity ligands. As magnetic susceptible materials are highly uncommon in biotechnological processes, target binding and selective separation of such particles from fermentation or reactions broths can be done in a single step. Since the magnetizable particles can be produced from iron salts and low priced polymers, a single-use implementation of these systems is highly conceivable. In this article, the principles of magnetizable particles, their synthesis and functionalization are explained. Furthermore, applications in the area of reaction engineering, microfluidics and downstream processing are discussed focusing on established single-use technologies and development potential.}, language = {en} } @article{ZientzBongaertsUnden1998, author = {Zientz, Evelyn and Bongaerts, Johannes and Unden, Gottfried}, title = {Fumarate regulation of gene expression in Escherichia coli by the DcuSR (dcuSR genes) two-component regulatory system}, series = {Journal of bacteriology}, volume = {Vol. 180}, journal = {Journal of bacteriology}, number = {No. 20}, issn = {1098-5530 (E-Journal); 0021-9193 (Print)}, pages = {5421 -- 5425}, year = {1998}, language = {en} } @article{SchwabHojdisLacayoetal.2016, author = {Schwab, Lukas and Hojdis, Nils and Lacayo, Jorge and Wilhelm, Manfred}, title = {Fourier-Transform Rheology of Unvulcanized, Carbon Black Filled Styrene Butadiene Rubber}, series = {Macromolecular Materials and Engineering}, volume = {301}, journal = {Macromolecular Materials and Engineering}, number = {4}, publisher = {Wiley-VCH}, address = {Weinheim}, issn = {1439-2054}, doi = {10.1002/mame.201500356}, pages = {457 -- 468}, year = {2016}, abstract = {Rubber materials filled with reinforcing fillers display nonlinear rheological behavior at small strain amplitudes below γ0 < 0.1. Nevertheless, rheological data are analyzed mostly in terms of linear parameters, such as shear moduli (G′, G″), which loose their physical meaning in the nonlinear regime. In this work styrene butadiene rubber filled with carbon black (CB) under large amplitude oscillatory shear (LAOS) is analyzed in terms of the nonlinear parameter I3/1. Three different CB grades are used and the filler load is varied between 0 and 70 phr. It is found that I3/1(φ) is most sensitive to changes of the total accessible filler surface area at low strain amplitudes (γ0 = 0.32). The addition of up to 70 phr CB leads to an increase of I3/1(φ) by a factor of more than ten. The influence of the measurement temperature on I3/1 is pronounced for CB levels above the percolation threshold.}, language = {en} } @article{Lassonczyk1989, author = {Lassonczyk, Beate}, title = {Fossile Bodenbildung in Nord-Somalia}, series = {Mitteilungen der Deutschen Bodenkundlichen Gesellschaft. 59 (1989), H. 2}, journal = {Mitteilungen der Deutschen Bodenkundlichen Gesellschaft. 59 (1989), H. 2}, isbn = {0343-107x}, pages = {927 -- 930}, year = {1989}, language = {de} } @article{SchoeningBiselliSelmeretal.2012, author = {Sch{\"o}ning, Michael Josef and Biselli, Manfred and Selmer, Thorsten and {\"O}hlschl{\"a}ger, Peter and Baumann, Marcus and F{\"o}rster, Arnold and Poghossian, Arshak}, title = {Forschung „zwischen" den Disziplinen: das Institut f{\"u}r Nano- und Biotechnologien}, series = {Analytik news : das Online-Labormagazin f{\"u}r Labor und Analytik}, volume = {Publ. online}, journal = {Analytik news : das Online-Labormagazin f{\"u}r Labor und Analytik}, publisher = {Dr. Beyer Internet-Beratung}, address = {Ober-Ramstadt}, pages = {11 Seiten}, year = {2012}, abstract = {"Biologie trifft Mikroelektronik", das Motto des Instituts f{\"u}r Nano- und Biotechnologien (INB) an der FH Aachen, unterstreicht die zunehmende Bedeutung interdisziplin{\"a}r gepr{\"a}gter Forschungsaktivit{\"a}ten.
