Black art

Gettering is a black art. It consists in forcing selected impurities (typically, transition metals) to diffuse toward unimportant regions of tlie device. This is often done by creating precipitation sites and perfoniiing heat treatments. The precipitation sites range from small oxygen complexes to layers such as an A1 silicide. The foniiation of such a... 

The balancing of a rotor certainly has changed from a black art with the introduction of more sophisticated equipment. While it is now much more scientific, it certainly is not a job for the novice. For several obvious...

As it carries the baggage of this considerable period of time, some new to the industry find it difficult to understand. With terms such as spew, mould dope, pig, drug room and cracking all having their own rubber-related meaning, it is little wonder that the industry is regarded by outsiders as a Black Art. 

Unfortunately, until component-based development becomes the norm and until project managers understand the economics of buying the kinds of domain-independent components described earlier, we will still be building many of them. If most of the elements of the technical architecture are already implemented, then estimating the development time for business functions becomes much less like a black art. 

Few terms have been more commonly used and abused in the scientific literature than nano. However, if one is able to sift through the vast amounts of nano literature, there are also numerous reports that are of both academic and commercial importance. This is particularly true for the field of catalysis in which rapid progress is being made that has transformed this once black art into a science, which is understood on a molecular and even atomic level. These gains have been particularly driven by the fields of surface and nanomolecular science with improvements in instrumentation and experimental techniques that have facilitated scientists observations on the nano-size scale.

As with gas—liquid systems, chemical engineering theorists have almost exclusively concerned themselves with the creation of surface area (drop formation), usually relating surface area creation to the expenditure of power raised to an index of around . These expressions are entirely empirical and of only guidance value in the absence of essential experimentation data. Drop coalescence remains a black art.

Several years ago the subject was regarded as a "black art". Now the technology allows the production of a uniform, high quality product that is free from failure. Much of the science behind the technology remains cloaked in uncertainty, but it is sure to become an important part of future developments. Today, environmental concerns have an impact on all aspects of commerce. Rubber-to-metal bonding is no exception, so the process is changing to reflect these concerns. 

My next decision required more thought. I had two options—I could wait there in my cell until I was taken down to appear before the tribunal, taking the risk that it would send me straight back up to the torturers. If that happened, my ensuing experiences were likely to be both unpleasant and prolonged, since I had no idea where my master had gone and to confess to assisting him in the black arts would be suicide. 

This text is intended to be a guide for both the novice to preparative HPLC, and as an aid to the chemical engineer planning to introduce this black art into the industrial environment. 

Too many chromatographic texts dwell heavily on a theoretical and mathematical complexity that bears little relevance to what you actually need to do in order to practice preparative HPLC. Hopefully this book will describe how to practically go about a preparative separation. It is designed to guide the reader through the choice of equipment and chromatographic modes with minimal fuss and with reference to only relevant formulae. Much of the black art will be removed by the hints and tips of a practitioner with over 20 year s experience in many modes of chromatographic separation.
