The PNIPAAm and PSA hydrogel films were prepared by means of in situ photopolymerization directly inside the fluidic channel of a microfluidic chip fabricated by combining Si and SU-8 technologies. The swelling/shrinking properties and height changes of the PNIPAAm and PSA films inside the fluidic channel were studied at temperatures of deionized water from 14 to 36 °C and different pH values (pH 3-12) of Titrisol buffer, respectively. Additionally, in separate experiments, the lower critical solution temperature (LCST) of the PNIPAAm hydrogel was investigated by means of a differential scanning calorimetry (DSC) and a surface plasmon resonance (SPR) method. Mass-flow measurements have shown the feasibility of the prepared hydrogel films to work as an on-chip integrated temperature- or pH-responsive microvalve capable to switch the flow channel on/off.}, language = {en} } @article{CanzoneriKruegerZangetal.2006, author = {Canzoneri, M. and Kr{\"u}ger, R. and Zang, Werner and Biselli, Manfred}, title = {Atmungsaktivit{\"a}t von S{\"a}ugerzellen: Kontinuierliche Onlineermittlung im Sch{\"u}ttelkolben}, series = {BIOforum. 3 (2006)}, journal = {BIOforum. 3 (2006)}, isbn = {0940-0079}, pages = {45 -- 47}, year = {2006}, language = {de} } @inproceedings{CapitainHeringTippkoetteretal.2016, author = {Capitain, C. and Hering, T. and Tippk{\"o}tter, Nils and Ulber, R.}, title = {Enzymatic polymerization of lignin model compounds and solubilized lignin in an aqueous ethanol extract}, series = {New frontiers of biotech-processes (Himmelfahrtstagung) : 02-04 May 2016, Rhein-Mosel-Halle, Koblenz/Germany}, booktitle = {New frontiers of biotech-processes (Himmelfahrtstagung) : 02-04 May 2016, Rhein-Mosel-Halle, Koblenz/Germany}, publisher = {DECHEMA}, address = {Frankfurt am Main}, pages = {151 -- 152}, year = {2016}, language = {en} } @article{CapitainRossJonesMoehringetal.2020, author = {Capitain, Charlotte and Ross-Jones, Jesse and M{\"o}hring, Sophie and Tippk{\"o}tter, Nils}, title = {Differential scanning calorimetry for quantification of polymer biodegradability in compost}, series = {International Biodeterioration \& Biodegradation}, volume = {149}, journal = {International Biodeterioration \& Biodegradation}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0964-8305}, doi = {10.1016/j.ibiod.2020.104914}, pages = {In Press, Article number 104914}, year = {2020}, abstract = {The objective of this study is the establishment of a differential scanning calorimetry (DSC) based method for online analysis of the biodegradation of polymers in complex environments. Structural changes during biodegradation, such as an increase in brittleness or crystallinity, can be detected by carefully observing characteristic changes in DSC profiles. Until now, DSC profiles have not been used to draw quantitative conclusions about biodegradation. A new method is presented for quantifying the biodegradation using DSC data, whereby the results were validated using two reference methods. The proposed method is applied to evaluate the biodegradation of three polymeric biomaterials: polyhydroxybutyrate (PHB), cellulose acetate (CA) and Organosolv lignin. The method is suitable for the precise quantification of the biodegradability of PHB. For CA and lignin, conclusions regarding their biodegradation can be drawn with lower resolutions. The proposed method is also able to quantify the biodegradation of blends or composite materials, which differentiates it from commonly used degradation detection methods.}, language = {en} } @article{CapitainWagnerHummeletal.2021, author = {Capitain, Charlotte and Wagner, Sebastian and Hummel, Joana and Tippk{\"o}tter, Nils}, title = {Investigation of C-N Formation Between Catechols and Chitosan for the Formation of a Strong, Novel Adhesive Mimicking Mussel Adhesion}, series = {Waste and Biomass Valorization}, volume = {12}, journal = {Waste and Biomass Valorization}, publisher = {Springer Nature}, address = {Cham}, issn = {1877-265X}, doi = {10.1007/s12649-020-01110-5}, pages = {1761 -- 1779}, year = {2021}, language = {en} } @article{CehreliAkpinarTemizArtmannetal.2015, author = {Cehreli, Ruksan and Akpinar, Hale and Temiz Artmann, Ayseg{\"u}l and Sagol, Ozgul}, title = {Effects of Glutamine and Omega-3 Fatty Acids on Erythrocyte Deformability and Oxidative Damage in Rat Model of Enterocolitis}, series = {Gastroenterology Research}, volume = {8}, journal = {Gastroenterology Research}, number = {5}, issn = {1918-2813}, doi = {10.14740/gr683w}, pages = {265 -- 273}, year = {2015}, language = {en} } @article{CesariRennekampffVinterstenetal.2004, author = {Cesari, Francesca and Rennekampff, Verena and Vintersten, Kristina and Vuong, Lam Giang and Seibler, Jost and Bode, J{\"u}rgen and Wiebel, Franziska F. and Nordheim, Alfred}, title = {Elk-1 knock-out mice engineered by Flp recombinase-mediated cassette exchange}, series = {Genesis : The Journal of Genetics and Development}, volume = {38}, journal = {Genesis : The Journal of Genetics and Development}, number = {2}, issn = {1526-968X}, doi = {10.1002/gene.20003}, pages = {87 -- 92}, year = {2004}, language = {en} } @article{CheenakulaHoffstadtKrafftetal.2022, author = {Cheenakula, Dheeraja and Hoffstadt, Kevin and Krafft, Simone and Reinecke, Diana and Klose, Holger and Kuperjans, Isabel and Gr{\"o}mping, Markus}, title = {Anaerobic digestion of algal-bacterial biomass of an Algal Turf Scrubber system}, series = {Biomass Conversion and Biorefinery}, volume = {13}, journal = {Biomass Conversion and Biorefinery}, publisher = {Springer}, address = {Berlin}, issn = {2190-6823}, doi = {10.1007/s13399-022-03236-z}, pages = {15 Seiten}, year = {2022}, abstract = {This study investigated the anaerobic digestion of an algal-bacterial biofilm grown in artificial wastewater in an Algal Turf Scrubber (ATS). The ATS system was located in a greenhouse (50°54′19ʺN, 6°24′55ʺE, Germany) and was exposed to seasonal conditions during the experiment period. The methane (CH4) potential of untreated algal-bacterial biofilm (UAB) and thermally pretreated biofilm (PAB) using different microbial inocula was determined by anaerobic batch fermentation. Methane productivity of UAB differed significantly between microbial inocula of digested wastepaper, a mixture of manure and maize silage, anaerobic sewage sludge, and percolated green waste. UAB using sewage sludge as inoculum showed the highest methane productivity. The share of methane in biogas was dependent on inoculum. Using PAB, a strong positive impact on methane productivity was identified for the digested wastepaper (116.4\%) and a mixture of manure and maize silage (107.4\%) inocula. By contrast, the methane yield was significantly reduced for the digested anaerobic sewage sludge (50.6\%) and percolated green waste (43.5\%) inocula. To further evaluate the potential of algal-bacterial biofilm for biogas production in wastewater treatment and biogas plants in a circular bioeconomy, scale-up calculations were conducted. It was found that a 0.116 km2 ATS would be required in an average municipal wastewater treatment plant which can be viewed as problematic in terms of space consumption. However, a substantial amount of energy surplus (4.7-12.5 MWh a-1) can be gained through the addition of algal-bacterial biomass to the anaerobic digester of a municipal wastewater treatment plant. Wastewater treatment and subsequent energy production through algae show dominancy over conventional technologies.}, language = {en} } @article{ChristophBahrenbergVryetal.2008, author = {Christoph, Thomas and Bahrenberg, Gregor and Vry, Jean de and Englberger, Werner and Erdmann, Volker A. and Frech, Moritz and K{\"o}gel, Babette and R{\"o}hl, Thomas and Schiene, Klaus and Schr{\"o}der, Wolfgang and Seibler, Jost and Kurreck, Jens}, title = {Investigation of TRPV1 loss-of-function phenotypes in transgenic shRNA expressing and knockout mice}, series = {Molecular and Cellular Neuroscience}, volume = {37}, journal = {Molecular and Cellular Neuroscience}, number = {3}, issn = {1044-7431}, doi = {10.1016/j.mcn.2007.12.006}, pages = {579 -- 589}, year = {2008}, language = {en} } @article{ClaessenGrefenMangetal.2010, author = {Claessen, O. and Grefen, Dana and Mang, Thomas and Dikland, H.
