Minerals Named in Honour of the Collaborators of the A.E New Data on Minerals. М., 2005. Vol. 40 125 UDC 549:069. MINERALS NAMED IN HONOUR OF THE COLLABORATORS OF THE A.E. FERSMAN MINERALOGICAL MUSEUM Svetlana N. Nenasheva Fersman Mineralogical Museum RAS, Moscow, [email protected] Almost three hundred years history of existence and development of the Fersman Mineralogical Museum is close- ly connected with names of widelyknown scientists who made an important contribution to development of min- eralogy. Names of 28 outstanding mineralogists, collaborators of the Museum, became a part of the history of min- eralogy forever. 23 mineral species, 9 mineral varieties, and stonyiron meteorites, pallasites, were named in their honour. In the article the scientific interests and attainments of collaborators of the Museum, whose names were conferred to minerals, are briefly described; also brief characteristic of these mineral species and varieties is given. 28 photos, 100 references. A history of foundation and development of sils (in all nearly 3000 samples), were written the Fersman Mineralogical Museum is closely by M.V. Lomonosov. M.V.

    1469 The Canadian Mineralogist Vol. 43, pp. 1469-1487 (2005) BORATE MINERALS OF THE PENOBSQUIS AND MILLSTREAM DEPOSITS, SOUTHERN NEW BRUNSWICK, CANADA JOEL D. GRICE§, ROBERT A. GAULT AND JERRY VAN VELTHUIZEN† Research Division, Canadian Museum of Nature, P.O. Box 3443, Station D, Ottawa, Ontario K1P 6P4, Canada ABSTRACT The borate minerals found in two potash deposits, at Penobsquis and Millstream, Kings County, New Brunswick, are described in detail. These deposits are located in the Moncton Subbasin, which forms the eastern portion of the extensive Maritimes Basin. These marine evaporites consist of an early carbonate unit, followed by a sulfate, and fi nally, a salt unit. The borate assemblages occur in specifi c beds of halite and sylvite that were the last units to form in the evaporite sequence. Species identifi ed from drill-core sections include: boracite, brianroulstonite, chambersite, colemanite, congolite, danburite, hilgardite, howlite, hydroboracite, kurgantaite, penobsquisite, pringleite, ruitenbergite, strontioginorite, szaibélyite, trembathite, veatchite, volkovskite and walkerite. In addition, 41 non-borate species have been identifi ed, including magnesite, monohydrocalcite, sellaite, kieserite and fl uorite. The borate assemblages in the two deposits differ, and in each deposit, they vary stratigraphically. At Millstream, boracite is the most common borate in the sylvite + carnallite beds, with hilgardite in the lower halite strata. At Penobsquis, there is an upper unit of hilgardite + volkovskite + trembathite in halite and a lower unit of hydroboracite + volkov- skite + trembathite–congolite in halite–sylvite. At both deposits, values of the ratio of B isotopes [␦11B] range from 21.5 to 37.8‰ [21 analyses] and are consistent with a seawater source, without any need for a more exotic interpretation.

  • Design Rules for Discovering 2D Materials from 3D Crystals
    Design Rules for Discovering 2D Materials from 3D Crystals by Eleanor Lyons Brightbill Collaborators: Tyler W. Farnsworth, Adam H. Woomer, Patrick C. O'Brien, Kaci L. Kuntz Senior Honors Thesis Chemistry University of North Carolina at Chapel Hill April 7th, 2016 Approved: ___________________________ Dr Scott Warren, Thesis Advisor Dr Wei You, Reader Dr. Todd Austell, Reader Abstract Two-dimensional (2D) materials are championed as potential components for novel technologies due to the extreme change in properties that often accompanies a transition from the bulk to a quantum-confined state. While the incredible properties of existing 2D materials have been investigated for numerous applications, the current library of stable 2D materials is limited to a relatively small number of material systems, and attempts to identify novel 2D materials have found only a small subset of potential 2D material precursors. Here I present a rigorous, yet simple, set of criteria to identify 3D crystals that may be exfoliated into stable 2D sheets and apply these criteria to a database of naturally occurring layered minerals. These design rules harness two fundamental properties of crystals—Mohs hardness and melting point—to enable a rapid and effective approach to identify candidates for exfoliation. It is shown that, in layered systems, Mohs hardness is a predictor of inter-layer (out-of-plane) bond strength while melting point is a measure of intra-layer (in-plane) bond strength. This concept is demonstrated by using liquid exfoliation to produce novel 2D materials from layered minerals that have a Mohs hardness less than 3, with relative success of exfoliation (such as yield and flake size) dependent on melting point.

  • Synthesis and Adsorption Behavior of Microporous Iron-Doped Sodium Zirconosilicate with the Structure of Elpidite
    Article Synthesis and Adsorption Behavior of Microporous Iron-Doped Sodium Zirconosilicate with the Structure of Elpidite Emad Elshehy Nuclear Materials Authority, P.O. Box 530, El-Maadi, Cairo 11728, Egypt; [email protected]; Tel.: +20-10-0819-7997 Abstract: Decontamination of water from radionuclides contaminants is a key priority in environ- mental cleanup and requires intensive effort to be cleared. In this paper, a microporous iron-doped zeolite-like sodium zirconosilicate (F@SZS) was designed through hydrothermal synthesis with various Si/Zr ratios of 5, 10, and 20, respectively. The synthesized materials of F@SZS materials were well characterized by various techniques such as XRD, SEM, TEM, and N2 adsorption–desorption measurements. Furthermore, the F@SZS-5 and F@SZS-10 samples had a crystalline structure re- lated to the Zr–O–Si bond, unlike the F@SZS-20 which had an overall amorphous structure. The fabricated F@SZS-5 nanocomposite showed a superb capability to remove cesium ions from ultra- dilute concentrations, and the maximum adsorption capacity was 21.5 mg g–1 at natural pH values through an ion exchange mechanism. The results of cesium ions adsorption were found to follow the pseudo-first-order kinetics and the Langmuir isotherm model. The microporous iron-doped sodium zirconosilicate is described as an adsorbent candidate for the removal of ultra-traces concentrations of Cs(I) ions.
