Strange materials

In the late seventeenth and early eighteenth centuries, alchemists began to doubt the idea that there were only four main elements. Their laboratory experiments uncovered a variety of strange materials that did not seem to fit the ancient pattern. For instance, alchemists discovered that they could produce airs or gases in their laboratories by burning different kinds of materials like wood and metals. According to the ancient classification, all of these gases should be the same element, but they acted differently when they were themselves burned. 

Similarly strange tilings happen to other materials. Above 5 GPa, CO spontaneously polymerizes the... 

The crystal quality depends on (1) inclusions that determine the content of impurities, and (2) shape and size distribution to which filterability of crystals is related. Formation of detrimental inclusions is caused by incorporation of strange bodies (gas, liquid, or solid) into the crystal. Any dirt, rust, or other fines in the solution can result in incorporation of these materials into the crystals. The mother liquor can also adhere to the crystal surface or can be... 

Hagley Museum and Library is the richest repository of material about Carothers scientific career. Marjorie McNinch was particularly helpful during my visit. Hagley s collection includes the correspondence between Carothers and Du Pont about his hiring, Carothers notebooks, Carothers letters to his close friend, John R. Johnson and transcripts of interviews conducted with Carothers associates by David A. Hounshell and John Kenley Smith, Jr., and by Adeline C. Strange. 

This article outlines the food contact legislation in the UK that applies to plastic articles and materials that come into contact with food. Key requirements are that materials must not transfer chemicals to food in quantities that cause a hazard to human health, or cause the food to become tainted with a strange taste or odour. The regulations also set out testing conditions that enable compliance with the requirements to be demonstrated. 

In our scenario, we consider a purely hadronic star whose central pressure is increasing due to spin-down or due to mass accretion, e.g., from the material left by the supernova explosion (fallback disc), from a companion star or from the interstellar medium. As the central pressure exceeds the threshold value Pq at static transition point, a virtual drop of quark matter in the Q -phase can be formed in the central region of the star. As soon as a real drop of Q -matter is formed, it will grow very rapidly and the original Hadronic Star will be converted to and Hybrid Star or to a Strange Star, depending on the detail of... 

In experimental scienee there is no substitute for experienee, but if certain procedures are followed and adapted, a number of pitfalls can be avoided. The following sections are written for the benefit of beginners in topography, as this is a field relatively strange to practitioners of diffraction. While most of the material here can already be found in the literature these works are out of print and much exists now only in the folklore. 

Oo-koo-he " He was barely able to believe his ears. It must have been incredible to him that this strange, weak creature, like something from another world, should directly inquire after a secret tradition of his people. I have no idea how many cultural conventions were overlooked, but after a bit more conversation, or what passes for conversation between people who share no common language, I was sure that he would try to help me. Days later, on my twenty-fifth birthday, I was brought a tarry goo wrapped into little leaf packets. I was never able to obtain a hallucinogenic experience from this material, but later analysis by the chemists of the Karolinska Institute in Stockholm confirmed the presence of di-methyltryptamine. Demetrius had been as good as his name. 

The quest for higher transition temperatures in superconductors took a strange turn when ceramic materials, possessing good, room-temperature metallic conductivity, were investigated. A study of simple binary compounds such as ZrN (Tc = 10.7 K), NbC (Tc =...
