A brazen band of robbers raids the New York Metropolitan Museum. Their target? The Prince's Emblazoned, an elaborate suit of armor rumored to be of surpassing occult significance. To ensure their escape, the thieves release an unprecedented weapon: a mist that turns men to stone. The Challenger Foundation, a team of dysfunctional and unorthodox superheroes, is called in to help. Led by the 900-year-old alchemist called the Promethean, the team must unravel the mystery of the fossilization solution and confront the architect of the plot, a deadly supernatural enemy thought dead for more than a century. Copper Knights and Granite Men is a witty and suspenseful superhero adventure that draws from the King in Yellow mythos and taps the secret occult history of North America. This first entry in the Challenger Confidential series contains the 66 page novelette, plus interior illustrations and a 33 page appendix exploring the Ascension Epoch universe.
This thesis describes the first and long-sought successful synthesis of a new pyrazole-expanded porphyrin, a higher analog of porphyrin. This "Siamese-Twin Porphyrin" provides two conjoined porphyrin-like coordination spheres, thus being able to accommodate two metal ions within the same ligand. In her thesis, Lina Blusch not only explains the challenging synthesis and characterization of the ligand system, but also its application to the synthesis of homo- and hetero-bimetallic Ni and Cu complexes. She observes interesting metal-metal-interactions in the complexes, that lead to a non-innocent multistep redox chemistry. The ligand system and its complexes show an intriguing twisted geometry, giving rise to helical chirality and other fascinating properties. This study explores the first steps and opens up a new chemistry of expanded porphyrins with the potential to biomimetic applications.
As William Sheldon eloquently put it in Penny Whimsy, Old copper, like beauty, appears to possess a certain intrinsic quality or charm...[with] an almost living warmth and personality not encountered in any other metal...You see rich shades of green, red, brown, yellow, and even deep ebony: together not elsewhere matched in nature save perhaps in autumn leaves...Early coppers are rich in die varieties, cracked dies, imperfect and unusual planchets, misstruck coins and other minor variations...It is therefore not surprising that to some extent the different die varieties are recognizable by characteristic color and surface texture, as well as by die breaks, peculiarities of the planchet and so on. New Jersey State Coppers shows that never were these words more true than in the case of the coins struck for New Jersey by Thomas Goasby, Albion Cox, Walter Mould, and Matthias Ogden from 1786 until as late as 1790. By way of introduction, the authors fully discuss the often tumultuous history of the New Jersey copper coinage and its creators alongside the equally compelling story of the men, like Dr. Edward Maris, who first appreciated the "living warmth and personality" of the coins and formed the great collections of the nineteenth and twentieth centuries. Every known New Jersey die variety is presented in minute detail with lavish enlarged full-color illustrations, condition censuses, as well as commentary on die states and other notable features. The authors also include such supplementary material as the original documents related to the eighteenth- century coining venture, imitations created for the collector market in the nineteenth century, as well as suggestions for developing a personal collection. New Jersey State Coppers will surely become the primary tool for the study of this coinage and the basis for deepening the understanding and appreciation of its charm as old copper.
