Crown jewels

The crown jewel in the application of the sulfoxide method to the assembly of natural products is the synthesis of a pentasaccharide from the antibiotic moeno-mycin A, wherein each glycosidic bond was formed in a stereocontrolled manner by one variant or another by the sulfoxide method (Scheme 4.63) [373],... [Pg.262]

The Aluminum Crown Jewels. In this chest, carefully preserved by die Aluminum Company of America at Pittsburgh, are the original buttons of die metal made by Charles M Hall in Oberlin, February 23, 1886 (left), die larger ones made by Hall in December, 1886 (center), and the first button or ingot (right) produced by the Aluminum Company of America... [Pg.605]

The next scene of the aluminum drama is laid in the United States. Henri Sainte-Claire Deville s process had made the metal a commercial product, but it was still expensive. Charles Martin Hall, a student at Oberlin College, inspired by the accounts which Professor F. F. Jewett had given of his studies under Wohler, decided that his supreme aim in life would be to devise a cheap method for making aluminum. In an improvised laboratory in the woodshed, and with homemade batteries, he struggled with this problem. On February 23,1886, this boy of twenty-one years rushed into his professors office and held out to him a handful of aluminum buttons. Since these buttons led to a highly successful electrolytic process for manufacturing aluminum, it is small wonder that the Aluminum Company of America now treasures them and refers to them affectionately as the crown jewels A beautiful statue of the youthful Charles M. Hall, cast in aluminum, may now he seen at Oberlin College (11, 55). [Pg.606]

Within an instant I was at Versailles. Benjamin Franklin was in conference with the king and queen of France. The royal couple were elaborately gowned in crowns, jewels, satins, and furs. Franklin, however, had a better sense of humor, and the members of the entourage were giving him their attention. [Pg.37]

Spinel is another simple oxide mineral. It is commonly seen today as a synthetic and may be any color. Natural red spinel was most prized as a gem, and usually was used as an imitation of ruby. Some notable pieces in the British and Russian crown jewels include large uncut spinels. These crystals are a deep red color and are distinctive because of their rough octahedral shape. [Pg.31]

A typical HTS campaign may require hundreds of thousands of samples delivered daily. Thus it is necessary to have all neat (solid) samples in liquid form in order to prepare and deliver them quickly. The first process in compound management to support HTS is dissolution of all solid samples into solutions—a process known as solubilization that makes samples readily available for biological testing. Another advantage to centralized compound solubilization, even for post-HTS activities, is to preserve the samples and reduce waste of the crown jewels. Compound solubilization usually requires (1) selection of solvent, (2) determining concentration and volume, (3) weighing of solids, and (4) solubilization. [Pg.195]

In light of such an impressive litany, it is no wonder that Herrington referred to the SSC as this national treasure. (He has also called it this crown jewel of science. ]... [Pg.190]

Chemical structure registration is an important activity that is necessary for drug discovery. The structures that have been developed by a pharmaceutical company constitute the "crown jewels" of chemical information, and they must be properly and securely archived. The registration process usually involves the process of extracting, cleaning, transforming, and loading the data—sometimes term ECTL. [Pg.377]

Before chemists developed inexpensive ways to produce pure aluminum, it was considered a somewhat precious metal. In fact, in 1855, a bar of pure aluminum metal was displayed at the Paris Exposition. It was placed next to the French crown jewels ... [Pg.7]

The museum trustees received requests for the safe-keeping of items of outstanding importance from numerous institutions and private individuals, and the quarry soon became a fabulous national treasure-house. Apan from artefacts from Bloomsbury and Kensington, Westwood also held collections from the Bodleian Library, the Imperial War Museum, and the Free French Museum of National Antiquities. Among the individual items to spend the war years in Wiltshire were the Rubens Ceiling from the Whitehall banqueting hall, the Crown Jewels, the Charles I statue from Whitehall and the bronze screen from the Henry VII Chapel in Westminster Abbey. [Pg.138]

A necklace containing the Hope Diamond. The Hope diamond has been linked with ill fortune including the maiden voyage of the Titanic. The dark blue diamond was, however, already in America at the time of that voyage. It appeared mysteriously in London in the early nineteenth century and is believed to have been recut from a large diamond (13.8 g) stolen from a museum housing the French crown jewels in 1792. Its last owner, Henry Winston, donated it to the Smithsonian Institution in Washington, D.C. with the wish that it formed part of a collection to rival that in the Tower of London. [Pg.110]

The explosive mixtures using nitromethane are the crown jewels of this section, the meat for our stew, if you will. The reasons for the primacy of the nitromethane formulas are twofold. First of all, the explosives produced using nitromethane are exceedingly powerful. They are much more powerful than the hydrazine based recipe just given, and they can even exceed the performance one would get from such staples of military hardware as C-4 or even pure RDX. [Pg.129]

The British Crown Jewels date from Charles II and so are relatively modem. Sadly, the Royal Sceptre lacks a magnificient rock crystal orb, which is the ancient emblem of divine kingship because it represents the priestly ability to compass the sun." The orb in the Royal Sceptre is often referred to as the Star of Jacob because in the prophecy of Balaam, the Sceptre represents the Messiah ... [Pg.125]

While the English Crown Jewels lack a rock crystalorb, the Honours of Scotland include such an orb in the Royal Sceptre of King James IV. Either Pope Innocent VII in 1491 or Pope Alexander VI in 1494 presented the Royal Sceptre to hum along with a Golden Rose. [Pg.125]

As the prerogative of royalty, purple has created a mystique for amethyst that elevated it above other types of quartz crystals. Coveted by Catherine the Great and embedded in the British Crown Jewels, amethyst was once considered a... [Pg.138]
