    Notes: A new type of reactor, an attrition bioreactor, was tested to achieve a higher rate and extent of enzymatic saccharification of cellulose than is possible with conventional methods. The reactor consisted of a jacketted stainless-steel vessel with shaft, stirrer, and milling media, which combined the effect of the mechanical action of wet milling with cellulose hydrolysis. The substrates tested were newsprint and white-pine heartwood. The performance of the reactor was excellent. The extent and rate of enzymatic hydrolysis could be markedly improved over other methods. The power consumption of the attrition bioreactor was also measured. The cellulase enzyme deactivation during attrition milling was not significant.

    Ethanol fermentation with cell recycling: Computer simulation (1983)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A mathematical model for glucose-to-ethanol fermentation at high yeast cell concentrations was developed. The feasibility of improving fermenter productivity over that of a conventional continuous-stirred-tank fermenter by using multiple stage reactors and yeast cell recycling was predicted by computer simulation. The optimum size distribution for multistage fermentors was obtained for different glucose feedstream concentrations and different glucose conversion levels. Productivity increases over a single-stage reactor ranged from 1.2-2.0 times. The use of yeast cell recycling to increase cell concentration and productivity increases of over 4.0 times that of a system without recycling.

    Magnetic order tuned by Cu substitution in Fe_{1.1−z}Cu_{z}Te (2012)
    American Physical Society (APS)

    Publication Date: 2012-07-03
    Description: Author(s): Jinsheng Wen, Zhijun Xu, Guangyong Xu, M. D. Lumsden, P. N. Valdivia, E. Bourret-Courchesne, Genda Gu, Dung-Hai Lee, J. M. Tranquada, and R. J. Birgeneau We study the effects of Cu substitution in Fe 1.1 Te, the nonsuperconducting parent compound of the iron-based superconductor, Fe 1+ y Te 1− x Se x , utilizing neutron scattering techniques. It is found that the structural and magnetic transitions, which occur at ∼ 60 K without Cu, are monotonically depressed ... [Phys. Rev. B 86, 024401] Published Mon Jul 02, 2012
