Large-scale production of oxymethylene dimethyl ethers
… by replacing fossil diesel fuel if their production is based on sustainable methanol. Various process concepts for their production were proposed and investigated, but most of them prevail signifcant bottlenecks, which prevent their demonstration and scale-up in the near future. One of the …

Large scale production of single wall carbon nanotubes
… developed into viable technologies. Current production levels are too low to meet the needs of manufacturers looking to develop products based on SWNTs. This is especially true for those looking to make structural polymer composites. Thus there is a need for large-scale production of SWNTs. …

Asynchronous stochastic learning curve effects in a large scale production system
Large scale production systems contain dynamically unequal distributing lead times and improvement rates. This has made it very problematic to statistically predict the ability of global partners to meet common deadlines simultaneously This system behavior can be attributed to the effects of …

Large-scale production and characterization of an engineered human olfactory receptor
… are the olfactory (smell) receptors - a large, highly related class of sensory G-protein coupled receptors that function together combinatorially to allow discrimination between a wide range of volatile and soluble molecules. However, the structural and functional mechanisms of these …

Potential sources for the large scale production of human protein C
… of protein C from alternative sources for the large-scale production and downstream recovery of highly purified and biologically active hPC. The partial characterization of the protein with respect to post-translational modifications which are essential for functionally active, was also …

Replacement of homogeneous acids in the conversion of meta-phenylenediamine to resorcinol by Heterogeneous Analogues
… A number of different processes for the production of resorcinol are available with each synthesis route having intrinsic advantages and disadvantages that differ from one process to another. A viable route to resourcinol in South Africa is via meta-dinitrobenzene due to the large-scale …
