The mineral is associated with shimazakiite, calcite and johnbaumite. The Vickers microhardness is 441 kg mm−2 (50 g load), corresponding to 4½ on the Mohs’ scale. The calculated density is 3.23 g cm−3. Electron microprobe analyses of kurchatovite gave empirical formulae ranging from Ca0.987(Mg1.004Fe0.020Mn0.001)Σ1.025 B1.992O5 to Ca0.992(Mg0.466Fe0.523)Σ0.989B2.013O5 based on O = 5, and kurchatovite forms a continuous solid solution in this range. The mineral is orthorhombic, Pbca, and the unit cell parameters refined from XRD data measured by a Gandolfi camera are a = 36.33(14), b = 11.204(3), c = 5.502(17) Å, V = 2239(12) Å3.Itis formed by a layer of MgO6–octahedra, a layer of CaO7–polyhedral and B2O5 consisting of two BO3–triangles. The kurchatovite from the Fuka mine was probably formed by supplying Mg and Fe to shimazakiite from hydrothermal solution at a temperature between 250 to 400 °C.

Thirty-one minerals, with nineteen distinct structure-types,contain isolated borate polyhedra. Twenty-seven minerals, with twenty-five distinct struc- ture-types, contain finite clusters of borate polyhedra. Ten minerals, with ten distinct structue-types, contain chains of borate polyhedra. Fifteen minerals, with thirteen distinct structue-types, contain sheets of borate polyhedra. Fifteen minerals, with thirteen distinct sEucture-types,contain frameworks of borate polyhedra.

  • STRONG and WEAK INTERLAYER INTERACTIONS of TWO-DIMENSIONAL MATERIALS and THEIR ASSEMBLIES Tyler William Farnsworth a Dissertati
    STRONG AND WEAK INTERLAYER INTERACTIONS OF TWO-DIMENSIONAL MATERIALS AND THEIR ASSEMBLIES Tyler William Farnsworth A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Chemistry. Chapel Hill 2018 Approved by: Scott C. Warren James F. Cahoon Wei You Joanna M. Atkin Matthew K. Brennaman © 2018 Tyler William Farnsworth ALL RIGHTS RESERVED ii ABSTRACT Tyler William Farnsworth: Strong and weak interlayer interactions of two-dimensional materials and their assemblies (Under the direction of Scott C. Warren) The ability to control the properties of a macroscopic material through systematic modification of its component parts is a central theme in materials science. This concept is exemplified by the assembly of quantum dots into 3D solids, but the application of similar design principles to other quantum-confined systems, namely 2D materials, remains largely unexplored. Here I demonstrate that solution-processed 2D semiconductors retain their quantum-confined properties even when assembled into electrically conductive, thick films. Structural investigations show how this behavior is caused by turbostratic disorder and interlayer adsorbates, which weaken interlayer interactions and allow access to a quantum- confined but electronically coupled state. I generalize these findings to use a variety of 2D building blocks to create electrically conductive 3D solids with virtually any band gap. I next introduce a strategy for discovering new 2D materials. Previous efforts to identify novel 2D materials were limited to van der Waals layered materials, but I demonstrate that layered crystals with strong interlayer interactions can be exfoliated into few-layer or monolayer materials.

  • New Mineral Names
    NEW MINERAL NAMES Bismuth jamesonite M. S. Sarrrerova, Bismuth sulfosalts of the Ustarasaisk deposits. Tru.d.y Mineralog. Muzeya Aka. Nauk S.S.S.R., N0.7, 112-116 (1955) (in Russian). Bismuth jamesonite was found as radiating aggregates of fine capillary crystals in cavities with quartz crystals in carbonate veinlets cutting arsenopyrite ore in the Ustaras- aisk deposits, western Tyan-Shan. The crystals are usually some mm. long, at times up to 1 cm. long, a fraction of a mm. in cross-section. They contain inclusions of native antimony, visible only under high magnification. A little realgar and cinnabar are associated minerals. The mineral is lead-gray, luster metallic, with one perfect cleavage. Hardness low. Under the microscope it is white, birefringent, strongly anisotropic with reddish reflections apparent only with immersion. Reflectivity 35%. Analysis by V. M. Senderova gave Bi 30.50, Sb 16.50, Pb 32.25, Fe 1.39, Cu 0.30, S.17.62, insol. 1.59; sum 100.1516,corresponding to PbS'(Bi, Sb)2S8. X-ray powder data are given. (The 26 lines given correspond very closely with those given for normal jamesonite by Berry, Mineralog. Mog.,25,597-608 (1940), except that strong lines given by Berry at 4.03 and 3.76 are not listed. M.F.) Drscussrox: The mineral is considered to be a variety of jamesonite. However, the ratio Bi: Sb:1.07:1, so that this is not a bismuthian jamesonite. The formula is given as PbS ' (Bi, Sb):Sa; the iron content given in the analysis is low for the formula generally accepted for normal jamesonite,4 PbS'FeS'3 SbrS3.

  • A Specific Gravity Index for Minerats
    A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951).

Calciborite occurs as milky white aggregates up to 1 mm in diame- ter with shimazakiite, fluorite, bornite and calcite. An electron microprobe analysis of calciborite gave an em- pirical formula (Ca0.999Mn0.001Co0.001)Σ1.001B1.999O4 based on O = 4. The unit cell parameters are a = 8.373(2), b = 13.811(8), c = 5.012(4) Å. The mineral is optically biaxial (−), α = 1.594(2), β = 1.654(2), γ = 1.672(2) and −2 2Vcalc. = 56°. The Vickers microhardness is 177 kg mm (50 g load), and the Mohs hardness number is 3.5. The measured and calculated densities are 2.88(2) and 2.881 g cm−3, respectively. The calciborite from the Fuka mine was probably formed by a reaction of boron-bearing fluids with limestone at a temperature between 250 and 300 °C. Keywords: Calciborite, Calcium borate, Skarn, Fuka INTRODUCTION Fuka mine. Calciborite, CaB2O4, is a very rare mineral of calcium bo- OCCURRENCE rates.
