“…One possible exception is that of the triple point T 3 for which an approach had to be made (see section 3.4) in the absence of direct experimental data. Other triple points of sulfur are known at higher pressures and temperatures [38][39][40] but the analysis of these are out of the scope of this paper.…”

“…The standard deviation is r(q ' ) = 1.635 kg Á m À3 , and r = 1.000. With these two equations (37) and (38), and the Wagner equation (4) the enthalpy of vaporization per mass unit D g ' h is easily obtained as function of temperature from the Clapeyron equation (5). This function is shown in figure 4(d) where the values calculated by West [33] are also represented.…”

“…The most extensive investigation of the P-T behavior of S has heen made by Vezzoli, et al [402][403][404][405][406]. Following examination of data from over 700 runs, they reported a diagram of "stability fields" which designates the p-T regions in which twelve different phases of solid Sexist [403,405].…”

Data on polymorphic phase changes and variation of melting temperature of the elements with pressure have been compiled and critically evaluated. Emphasis has been placed on work done at pressures exceeding 1 kbar. Pressure-temperature phase diagrams showing first•order solid•solid phase boundaries and/or melting curves derived from the best available data are given for 58 elements. In• formation on the crystal structures of high•pressure polymorphs is also reviewed. Those elements that exist in the gaseous state at room temperature and pressure are not included.

“…However, in a series of papers, Vezzoli, Dachille, and Roy first showed otherwise in definitive P-T phase equilibrium diagrams [G. C. Vezzoli and R. J. Zeto, unpublished data] [25][26][27] (Fig. Albeit, the first law of material science states that ''structure determines propertie's, where one found liquid regions in the T-P space, with very different properties-hence structures-it was strictly taboo to discuss ''polymorphism'' in liquids.…”

This paper demonstrates how glass has provided one of the earliest, and still rare, examples of controlled use of science at the nanolevel in a well‐established gigatechnology. The glass community—from the Venetian glass makers (and the science of luminaries such as Michael Faraday and Isaac Newton) down through major industrial successes such as glass–ceramics—are examples of excellent nanoengineers practicing clever applications of manipulation of matter at the nano and subnano scale. This paper describes the evolution of the understanding of nanoheterogeneity of the structure (and composition of virtually all useful glasses) that has been the key evolutionary “invention” in this process. It then makes the case that glass (and polymer) technology has an enormous advantage over all of the nanomaterial technologies that are confronted with the enormous barrier of assembling large numbers of very small particles into useful products on a large scale, as recognized by the recently anointed patron saint of the present nanofever, Richard Feynman, in his only paper in the field. Finally, this paper introduces glass scientists to a radically new opportunity via a totally new way to convert crystalline matter into glasses (noncrystalline solids)—for all scientists interested in the glassy state.
