38Th RMS Program Notes
E.fu\wsoil 'og PROGRAM Thursday Evening, April 14, 2011 PM 4:00-6:00 Cocktails and Snacks – Hospitality Suite 400 (4th Floor) 6:00-7:45 Dinner – Baxter’s 8:00-9:15 THE GUALTERONI COLLECTION: A TIME CAPSULE FROM A CENTURY AGO – Dr. Renato Pagano In 1950, the honorary curator of the Museum of Natural History in Genoa first introduced Dr. Renato Pagano to mineral collecting as a Boy Scout. He has never looked back. He holds a doctorate in electrical engineering and had a distinguished career as an Italian industrialist. His passion for minerals has produced a collection of more than 13,000 specimens, with both systematic and aesthetic subcollections. His wife Adriana shares his passion for minerals and is his partner in collecting and curating. An excellent profile of Renato, Adriana, and their many collections appeared earlier this year in Mineralogical Record (42:41-52). Tonight Dr. Pagano will talk about an historic mineral collection assembled between 1861 and 1908 and recently acquired intact by the Museum of Natural History of Milan. We most warmly welcome Dr. Renato Pagano back to the speakers’ podium. 9:15 Cocktails and snacks in the Hospitality Suite on the 4th floor will be available throughout the rest of the evening. Dealers’ rooms will be open at this time. All of the dealers are located on the 4th floor.

Robinson Associate Professor of Materials Science and Engineering Dissertation Advisor Chair of Committee Mauricio Terrones Distinguished Professor of Physics, Chemistry, and Materials Science and Engineering Roman Engel-Herbert Associate Professor of Materials Science and Engineering, Chemistry and Physics Saptarshi Das Assistant Professor of Engineering, Science & Mechanics John Mauro Professor of Materials Science and Engineering Chair, Intercollege Graduate Degree Program Associate Head for Graduate Education, Materials Science and Engineering *Signatures are on file in the Graduate School iii ABSTRACT Rapid development in Semiconductor research has brought excitement and challenges. New materials have pushed both academic and industry progress forward at a fast pace. Since the discovery of one-atomic layer of graphene in 2004, tremendous efforts have been devoted to pushing its properties to meet the technology demands, establish metrics and help accomplish milestones. The family of two-dimensional materials continue to expand. Transition metal dichalcogenides (TMDs) help compensate for the zero-bandgap of graphene and greatly increase the opportunities for their applications in electronics, optoelectronics, bioelectronics and medical- related applications. To enable electronic chips with higher density and faster processing/switching speeds and address technology bottlenecks, new correlated or functionalized two-dimensional materials are being positioned under the research spotlight. -

Powell ABSTRACT Incorporation of low level radioactive waste in cementitious materials is an important waste disposal technology in practice at a U.S. DOE facility, the Savannah 99 River Site (SRS), Aiken, SC. One of the major risk drivers, technetium ( Tc) (t1/2: 2.11 x 105 y), has been immobilized in saltstone through reductive precipitation. The saltstone VII - mixture is used to achieve chemical reduction of soluble Tc O4 (aq) into relatively IV insoluble Tc species (oxides and sulfides) via the Fe/S based compounds in the slag component. -
Re Sulfides from Zhelos and Tokty-Oi Intrusions (East Sayan, Russia)
Article Re Sulfides from Zhelos and Tokty-Oi Intrusions (East Sayan, Russia) Tatiana B. Kolotilina 1,*, Aleksey S. Mekhonoshin 1 and Dmitriy A. Orsoev 2 1 A.P. Vinigradov Institute of Geochemisry Siberian Branch of Russian Academy of Science, 664033 Irkutsk, Russia 2 Geological Institute Siberian Branch of Russian Academy of Science, 670047 Ulan-Ude, Russia * Correspondence: [email protected].; Tel.: +7-3952-42-4601 Received: 1 July 2019; Accepted: 6 August 2019; Published: 7 August 2019 Abstract: Re sulfides were discovered in Cu–Ni–platinum-group elements (PGE) ores of the Zhelos and Tokty-Oi intrusions. These intrusions can be considered as products of the mantle superplume responsible for Rodinia’s break-up. The mineral compositions were determined in situ in polished samples. Electron microprobe analyses were mostly consistent with a general formula of (Cu,Fe,Mo,Os,Re)5S8, (Cu,Fe,Mo,Os,Re)4S7, and (Cu,Fe,Mo,Re)S2. One of the major features of Re sulfide from the Zhelos intrusion is its high osmium content. The ΣMe/S ratio for a part of our data is consistent with that of the tarkianite. Re sulfides from the Tokty-Oi have a ΣMe/S ratio similar to those in rheniite or dzeskazganite, but differ from them by the presence of Fe and Cu and the metal-to-metal ratio. The localization of the Re sulfide within the chalcopyrite suggests its crystallization from the residual Cu-rich liquid. Keywords: rhenium; Re–Cu–Fe ± Mo ± Os sulfide; Cu–Ni–PGE deposit; immiscible sulfide liquid; Zhelos; Tokty-Oi; East Sayan; Russia 1. -

ABSTRACT The chemical and physical properties of rhenium render it a highly demanded metal for advanced applications in im- portant industrial fields. This very scarce element occurs mainly in ores of porphyry copper-molybdenum deposits as- sociated with the mineral molybdenite, MoS2, but it has also been found in granite pegmatites and quartz veins as well as in volcanic gases. Molybdenite is a typical polytype mineral which crystal structure is based on the stacking of [S- Mo-S] with molybdenum in prismatic coordination by sulphide anions; however, it is not yet clearly established if rhe- nium ions replace Mo4+ cations in a disordered way or else, if such replacement gives rise to dispersed nanodomains of a rhenium-rich phase. -

CINNABAR (Mercury Sulfide) Minerals | by Name | by Class | by Groupings | Search | Sulfides
CINNABAR (Mercury Sulfide) Minerals | By_Name | By_Class | By_Groupings | Search | Sulfides THE MINERAL CINNABAR ● Chemistry: HgS, Mercury Sulfide ● Class: Sulfides and Sulfosalts ● Uses: primary ore of mercury, a pigment and as a minerals specimen. ● Specimens Cinnabar is a colorful mineral that adds a unique color to the mineral color palette. Its cinnamon to scarlet red color can be very attractive. Well shaped crystals are uncommon and the twinned crystals are considered classics among collectors. The twinning in cinnabar is distinctive and forms a penetration twin that is ridged with six ridges surrounding the point of a pryamid. It could be thought of as two scalahedral crystals grown together with one crystal going the opposite way of the other crystal. Cinnabar was mined by the Roman Empire for its mercury content and it has been the main ore of mercury throughout the centuries. Some mines used by the Romans are still being mined today. Cinnabar shares the same symmetry class with quartz but the two form different crystal habits. PHYSICAL CHARACTERISTICS: ● Color is a bright scarlet or cinnamon red to a brick red. ● Luster is adamantine to submetallic in darker specimens. ● Transparency crystals are translucent to transparent. ● Crystal System is trigonal; 32 ● Crystal Habits: individual, well formed, large crystals are scarce; crusts and crystal complexes are more common; may be massive, or in capilary needles. Crystals that are found tend to be the six sided trigonal scalahedrons that appear to have opposing three sided pyramids. It also forms modified rhombohedrons, prismatic and twinned crystals as discribed above. ● Cleavage is perfect in three directions, forming prisms.
