“…These results are consistent with results from other systems where sintered targets were compared to solidified targets [18]. The basic explanation is related to the relative density of the targets.…”

“…The implication of this result is that if one uses a spectroscopic technique on the plume to determine composition of an unknown sample, there could be errors due to differential scattering in the plume and the limited detection angle [18]. However, we have shown that the particulates are not affected by such plume scattering and maintain the target composition.…”

“…If we calculate n as a function of x for a range of frequencies we get a set of n-curves; the envelope of these curves gives the maximum amplification factor N which occurs at any x.

The eN Method for Transition Prediction. Historical Review of Work at TU Delft

A historical review of work at TU Delft on the e N method for transition prediction is presented. The method is shown to be applicable to boundary layers with pressure gradient, suction and separation. Some applications to airfoil design will be discussed. An explanation will be given of the reason for the success of this linear theory to "predict" the position of transition which itself is a highly non-linear phenomenon. It will also be explained why the velocity profile shape factor H is a suitable parameter to characterize stability diagrams for flows with and without suction. Finally a new database method will be presented that is based on the observation that many stability diagrams show a remarkable similarity when properly scaled and shifted. The discussion will be restricted to two-dimensional incompressible flow.

Towards Biocatalytic Synthesis of β-Lactam Antibiotics

et al. 2001

View full text Add to dashboard Cite

This review describes the remarkable transition in the manufacture of β‐lactam antibiotics, which is driven by the desire to reduce or eliminate the production of waste and the dependence on organic solvents. To this effect, traditional chemical procedures are gradually being replaced by biotransformations. The β‐lactam antibiotics industry has led the way in the introduction of biocatalysis in the fine chemicals industry by replacing the chemical multi‐step process for the penicillin nucleus 6‐aminopenicillanic acid (6‐APA) by an enzymatic one in the early 1990's. Recently, bioprocesses have been developed for the synthesis of the cephalosporin nucleus, 7‐aminodeacetoxycephalosporanic acid (7‐ADCA) from a penicillin precursor and will shortly be commercialized. Thirty years of research have now resulted in viable enzymatic procedures for coupling the β‐lactam nuclei with D‐phenylglycine side‐chains. The necessary adaptations in the synthesis of the side‐chain donors have likewise resulted in more efficient procedures. 1 Introduction 2 Semi‐Synthetic β‐Lactam Antibiotics: Industrial Production Prior to 1985 3 Biocatalytic Synthesis of β‐Lactam Nuclei 3.1 6‐Aminopenicillanic Acid 3.2 7‐Aminodeacetoxycephalosporanic Acid 4 Biocatalytic Routes to Side‐Chains 4.1 Synthesis of the Side‐Chain Building Blocks 4.2 Synthesis of Activated Side‐Chain Donors 5 Enzymatic Coupling of the Side‐Chains to the β‐Lactam Nuclei 5.1 Chemical Procedures 5.2 Enzymatic Coupling 5.3 Practical Procedures for Enzymatic Coupling6 Conclusion and Future Outlook
